Unable to install OctoLapse on Octo4a with OctoPrint Version 1.8.7

[Cedric9602]

What were you doing when the problem occurred

I have tried to install OctoLapse the last days but was not successfull at it.. If i try to install it directly via the plugin repository I receive the folloing error: × python setup.py egg_info did not run successfully. │ exit code: 1

Via the link https://github.com/FormerLurker/Octolapse/archive/refs/heads/devel.zip I get the following errors × python setup.py bdist_wheel did not run successfully. │ exit code: 1 ... compilation terminated. error: command 'gcc' failed with exit code 1

I am really new to OctoPrint and did search really long to help myself but I am out of ideas now.. I already installed a ton of packages via the web terminal of Octo4a: apk add cmake apk add py3-setuptools apk add py3-wheel apk add py3-pip apk add py3-pillow apk add gcc apk add build-base apk add alpine-sdk apk add clang apk add py3-clang

pip3 install clang pip3 install --upgrade pip setuptools wheel pillow tornado pip3 install libevent-dev pip3 install ez_setup

What should have happened?

Install should work

What happened instead?

Mentioned errors

Operating System running OctoPrint and Octolapse

Octo4a 1.2.4 on NVIDIA Shield with Android 7

Browser and version of browser, operating system running browser

Microsoft Edge

If any more information is needed please tell me :) I would really like to take some cool OctoLapse timelapse recordings

Thanks in advance!

It's not only the typo in required pillow version, gcc in Alpine Linux 3.17 (base of Octo4a) won't compile pillow and can't be downgraded

[FormerLurker]

@9cento, have you tried installing the devel build? I just promoted this to master and added a release (check for updates in the Software Update plugin in OctoPrint). I've gotten several reports of success with Octo4a, and am hoping this isn't something new.

[9cento]

@FormerLurker I tried the devel branch yesterday if I remember correctly, without success, but I will try the new main release asap and thank you for your celery response

[9cento]

@FormerLurker Sadly, still similar issues. I tried the new OctoLapse-0.4.3 with Octo4a-1.2.4 (who had success with the installation of OctoLapse probably runs an older version of Octo4a but I can't downgrade since there's no Android 11 compatibility in the previous releases) and Octoprint-1.8.7, all of this runs on top of an Alpine Linux virtual environment that enables Octo4a to work by default. The Alpine Linux version is 3.17.1, the build-base package is 0.5-r3 and the gcc version is 12.2.1_git20220924-r4 (which as far as I can tell is the root cause of the problem since it won't compile anything as you will see in the log). I hope you can find a solution and thanks for your effort, very appreciated. Here's the full log straight from Octoprint itself: Log on Pastebin since it is very long.

[FormerLurker]

Did you go to the settings in the octo4a app and check the box that says "install plugin extras" ?

[9cento]

@FormerLurker yes I did and it went smooth. I hope it's not an incompatibility between Android 11 and Alpine Linux 3.17 because that would be a major pain in the a$$

[FormerLurker]

I will look at the log when I have some time, but my guess is that there is some issue with the compiler (maybe it isn't installed? No clue)

[9cento]

@FormerLurker thanks for your time. As for the compiler I verified and it's there, it just doesn't work as expected, I also force-reinstalled it but still same problem

[FormerLurker]

I did find this during a brief scan (am mobile ATM): gcc: fatal error: cannot execute 'cc1plus': execvp: No such file or directory

[9cento]

@FormerLurker also checked it and all ok, checked even the PATH environment variables and it's all on spot, I'm pretty much lost at this point

[FormerLurker]

You could try compiling the c manually and see how that goes. If you get a binary out of it, I can walk you through a manual install. Worst case maybe we learn something? I will spend some time researching tomorrow.

[9cento]

@FormerLurker I'm afraid my knowledge stops right before that lol so I'll do my own research but I can't guarantee I will nail it

[FormerLurker]

Understood. Did you try this:

apk add g++

??

[9cento]

@FormerLurker yep, it's in place

[FormerLurker]

Ok. I am on discord with the same username. Hit me up tomorrow at around 11CT and we can debug. In the meantime, see if you can try a manual compile. I realize that is a big ask, but you may gain some additional insight that could prove useful.

[9cento]

@FormerLurker uhm this is very strange: if I run as # gcc helloworld.c -o helloworld I get -ash: gcc: Permission denied, but if I run /usr/bin/gcc helloworld.c -o helloworld it compiles smoothly, the same applies to g++. After this I double-checked my PATH and /usr/bin is indeed there. Finally I run find / -name gcc 2>/dev/null just to check for potential conflicting gcc packages and it printed the following: /usr/libexec/gcc /usr/lib/gcc /usr/bin/gcc It's worth to mention that /usr/libexec and /usr/lib are NOT in my PATH, frankly I don't know if it's supposed to be like that.

@FormerLurker ok partial progress: I managed to get gcc to work in the ssh shell by just prompting gcc instead of /usr/bin/gcc by adding alias gcc='/usr/bin/gcc to etc/profile (applied this very same dirty fix for g++), this way I was able to complile my example by just prompting gcc helloworld.c -o helloworld. Then I tried to reinstall again OctoLapse-0.4.3 via Octoprint's plugins manager by manually adding the new url, sadly it bitched again about gcc: fatal error: cannot execute 'cc1plus': execvp: No such file or directory (I guess I'll dig more into that now). Just for the sake of it I also tried to install the plugin via the ssh shell but same result, will report back if there will be any new findings

@FormerLurker I think we are almost there: I managed to fix gcc: fatal error: cannot execute 'cc1plus': execvp: No such file or directory with a symlink, now I'm getting this: gcc -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Os -fomit-frame-pointer -g -O2 -Os -fomit-frame-pointer -g -O2 -Os -fomit-frame-pointer -g -O2 -DTHREAD_STACK_SIZE=0x100000 -fPIC -DIS_PYTHON_EXTENSION=1 -I/usr/include/python3.10 -c octoprint_octolapse/data/lib/c/extruder.cpp -o build/temp.linux-armv8l-cpython-310/octoprint_octolapse/data/lib/c/extruder.o -O3 -std=c++11 In file included from octoprint_octolapse/data/lib/c/extruder.cpp:2: octoprint_octolapse/data/lib/c/logging.h:3:10: fatal error: string: No such file or directory 3 | #include <string> | ^~~~~~~~ compilation terminated. error: command 'gcc' failed with exit code 1 As you can see now the problem is no longer related to the actual execution capability of the gcc command in general but it rather resides in how that manages the code which is trying to (finally!) compile. So I was thinking that maybe if g++ is used to compile instead of gcc the installation could go trough, correct me if I'm wrong, but I don't know how to force such behavior (messing with the source code is probably needed but sadly it's out of my scope). That's all from me for now, do your tricks and let me know once you'll have time, no need to hurry obviously 🤗

@FormerLurker Yet another update: managed to force the use of g++ instead of gcc but it didn't change a thing, same error.

[FormerLurker]

@9cento, looks like there is some progress! How did you 'force' the use of g++? Did you do this maybe:

export CXX=g++

before installing?

Let's try a c++ file instead of a c file and see if you can compile that with g++. Create a file named hello_world.cpp and fill it with the following content:

#include <iostream>
#include <string>

int main() {
    std::string greeting = "Hello, World!";
    std::cout << greeting << std::endl;
    return 0;
}

Then compile it with the following command: g++ -o hello_world hello_world.cpp

And run it (if the compilation was successful) with this: ./hello_world

You'll notice that I included here, which is failing during the Octolapse install.

Fyi, I'm online (FormerLurker#5525) if you want to chat instead. I may delete this line, so copy the username :)

[9cento]

@FormerLurker username copied for future reference, but for now I'd prefer to talk here even if it's less pratical, just in case someone will find himself in the same spot with this obscure issue. To compile with g++ I temporarily forked the repo and put self.compiler.set_executable("compiler_so", ["g++"]) in setup.py, I don't know how but it did the trick (thanks ChatGPT lol) because when it printed the usual error it cited g++ instead of gcc. As for the hello_world.cpp file, it compiled and run no problem.

[FormerLurker]

So, for some reason, the compiler is unable to locate the standard libraries, but only when running it through octoprint. V strange. Perhaps this is masking some other issue?

When you installed g++, did you include the python dev libraries: apk add g++ python3-dev I'm guessing there would be a different error message than a missing string library....

Have you tried running setup.py for Octolapse manually? You should be able to activate the virtual environment and run setup.py yourself. This guide for getting started with plugin development should explain some of the nuance.

[9cento]

Nope, same thing from the ssh shell.

Yep, that's all on place.

Yeah same error sadly.

I'm really sorry I don't understand much of what is described above but I think I have the same issue. I'm putting my pluginmanager console log here in case it might help. I appreciate all the hard work being done...Thanks. plugin_pluginmanager_console.log

Basically we're fucking around and trying to find out, btw thanks for your contribution!

[yaukari2]

was a solution found?

[9cento]

was a solution found?

Personally, I wasn't able to find a workaround and gave up on the thing. You may want to ask @FormerLurker if there are any news on that.

[FormerLurker]

I just need to replicate the issue, which probably means purchasing some hardware. If anyone has any suggestions or steps to reproduce the issue on some common hardware, that would be helpful.

I am also considering submitting the octolapse C++ extensions to pypi so it can be installed via PIP, or creating some GitHub runner to make precompiled binaries for all of the common platforms. Anyone with experience in doing either of these would be my hero, as the compilation steps have always been an issue for me. I do have CI for the Arcwelder c++ using cmake, so it is possible, and I believe that GitHub now supports some arm compilation.

[9cento]

@FormerLurker I can't remember right now if I already tried that but give Androd Studio's AVD emulator a try, just as a reminder the issue manifests on Android 11 only so keep that in mind and thanks in advance as always

[9cento]

@FormerLurker ok good news: I can confirm that the issue is replicable on Android Studio's AVD emulator with Android 11 so no extra physical hardware is needed to troubleshoot it. Also, I'm almost sure that it's not even a cpu architecture/instructions related problem since during octo4a installation it baked an x86 bootstrap for Alpine Linux while so far we've only tested the thing on Arm based devices. Now it's up to you my friend, my knowledge stops here, so sadly I can't probably be of much help any further, but anyway feel free to hit me up here or on Discord for whatever!

[9cento]

@FormerLurker sorry to bother you, I just wanted to know if there are any updates on this issue

[FormerLurker]

Thanks for the nudge! Unfortunately, not yet. I will try to make progress this weekend. Please keep pestering me.

[9cento]

Please keep pestering me.

Man I went radio silent for like a month, nobody is pestering you

[chis54]

I posted in another issue thread (https://github.com/FormerLurker/Octolapse/issues/911#issuecomment-1595942980 and log posted with comment) and the issue may be related to what you were discussing here. I am running Octo4a v1.2.5 on a Pixel 5 with Android 13. Other plugins install and run just fine.

[calif94577]

I think I am having the same issue. Here is the error, too long to comment here. https://pastebin.com/NXpUAbPi

[BaTaTaAdb]

Same issue here. Bump ^

Please keep pestering me.

I don't think that was sarcasm I think he legit wanted you to stay on top of him so he doesn't forget.

@FormerLurker Any progress? Saw on the issue linked 3 comments above this that someone made a fork that might be working? No sure. Thanks!

[BaTaTaAdb]

Hey. I've been researching and found that by installing an older version of octolapse I got it to install on my huawei P40 lite with the latest octo4a version. Found it on #888.

install it using the following link: https://github.com/a-c-m/Octolapse/archive/refs/heads/master.zip

Tested it out and it works flawlessly! It's the only version that I got working so for now I'll keep using it. If you have any luck with another Octolapse build let me know!

[shashwat001]

After 3 days of effort I am able to install it. Enable ssh and install the package as follows. pip install "https://github.com/FormerLurker/Octolapse/archive/master.zip"

It will start with following error:

gcc: fatal error: cannot execute 'cc1plus': execvp: No such file or directory

Resolution is to add cc1plus to path. Find the location of cc1plus using the command /usr/bin/gcc --print-prog-name=cc1plus and either add the path to PATH envvar, or symlink cc1plus to an existing path.

Next error would be

gcc -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Os -fomit-frame-pointer -g -O2 -Os -fomit-frame-pointer -g -O2 -Os -fomit-frame-pointer -g -O2 -DTHREAD_STACK_SIZE=0x100000 -fPIC -DIS_PYTHON_EXTENSION=1 -I/usr/include/python3.10 -c octoprint_octolapse/data/lib/c/extruder.cpp -o build/temp.linux-armv8l-cpython-310/octoprint_octolapse/data/lib/c/extruder.o -O3 -std=c++11 In file included from octoprint_octolapse/data/lib/c/extruder.cpp:2: octoprint_octolapse/data/lib/c/logging.h:3:10: fatal error: string: No such file or directory 3 | #include \<string> | ^~~~ compilation terminated. error: command 'gcc' failed with exit code 1

Its because installation is not able to find string in include dirs. This command works directly but somehow not working with pip. The solution is to add include directories in setup.py file. This will require extracting the directory say /tmp/Octolapse-master.

Modify setup.py and add include_dirs to cpp_gcode_parser Extension variable

cpp_gcode_parser = Extension(
    'GcodePositionProcessor',
    sources=plugin_ext_sources,
    language="c++",
    include_dirs=['/usr/include/c++/12.2.1', '/usr/include/c++/12.2.1/armv6-alpine-linux-musleabihf']
)

If /usr/include/c++/12.2.1/armv6-alpine-linux-musleabihf path is not same, search for c++config.h file location and use that path. exclude bits from path as file is included as bits/c++config.h find / -name c++config.h 2>/dev/null

Install using pip install file:///tmp/Octolapse-master

Last error would likely be

gcc -shared -Wl,--as-needed,-O1,--sort-common -Wl,--as-needed,-O1,--sort-common build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/extruder.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/gcode_comment_processor.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/gcode_parser.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/gcode_position.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/gcode_position_processor.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/logging.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/parsed_command.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/parsed_command_parameter.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/position.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/python_helpers.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/snapshot_plan.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/snapshot_plan_step.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/stabilization.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/stabilization_results.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/stabilization_smart_gcode.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/stabilization_smart_layer.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/trigger_position.o build/temp.linux-armv7l-cpython-310/octoprint_octolapse/data/lib/c/utilities.o -L/usr/lib -o build/lib.linux-armv7l-cpython-310/GcodePositionProcessor.cpython-310-arm-linux-gnueabihf.so gcc: fatal error: '-fuse-linker-plugin', but liblto_plugin.so not found

This is library not found error on the last step of compilation. I tried many ways to add library path by changing setup.py and adding env var LD_LIBRARY_FLAG but nothing worked. Eventually failed to get it done by pip way. However, direct command was working. So I added editable flag to pip command.

pip install -e file:///tmp/Octolapse-master

This would again fail on above error but a build directory would be created and not cleaned. Execute the same gcc command from project folder. Once successful, run pip command again. The successful installation of plugin should be shown. This can be confirmed from pip pip list
