Add toolchain and release package for Linux x86

[rfamp]

After successfully building the IDE on a 32Bit machine I get these error message, when I want to compile something: Cannot run program "/home/eagle/Downloads/Arduino-esp8266/build/linux/arduino-1.6.1/hardware/tools/esp8266/xtensa-lx106-elf/bin/xtensa-lx106-elf-g++": error=2, File or Path not found

What can I do?

Greetings from Germany Joshua

[SamuelGold]

I solve this problem, downolad zip from here and unpack https://github.com/jcmvbkbc/crosstool-NG After do this:

cd crosstool-NG-lx106-g-/ ./bootstrap ./configure --prefix=pwd && make make make install ./ct-ng xtensa-lx106-elf ./ct-ng build cp -r ./builds/xtensa-lx106-elf/ /YOUR_PATH/arduino-1.6.1/hardware/tools/esp8266/

Hope it helps!

Hi, i did it (compiling was fine)and i get this messages over and over: Arduino: 1.6.1 (Linux), Platine: "Generic ESP8266 Module, 80 MHz, 115200"

Cannot run program "/home/eagle/Dokumente/arduino-1.6.1/hardware/tools/esp8266/xtensa-lx106-elf/bin/xtensa-lx106-elf-g++": error=2, File or Path not found

The file xtensa-lx106-elf-g++ isn in the folder as it should be... What can i do? joshua

[SamuelGold]

Hello! Go to the folder crosstool-NG-lx106-g-/ cd crosstool-NG-lx106-g-/ Then run this: cp -r ./builds/xtensa-lx106-elf/ /home/eagle/Dokumente/arduino-1.6.1/hardware/tools/esp8266/

Folder xtensa-lx106-elf is in crosstool-NG-lx106-g-/builds, this command copy it to /home/eagle/Dokumente/arduino-1.6.1/hardware/tools/esp8266/ Or you can copy it manually from crosstool-NG-lx106-g-/ to /home/eagle/Dokumente/arduino-1.6.1/hardware/tools/esp8266

[rfamp]

I did it, but the file isn't there: ls in /Dokumente/arduino-1.6.1/hardware/tools/esp8266/xtensa-lx106-elf/bin xtensa-lx106-elf-addr2line xtensa-lx106-elf-elfedit xtensa-lx106-elf-gdb xtensa-lx106-elf-ranlib xtensa-lx106-elf-ar xtensa-lx106-elf-gcc xtensa-lx106-elf-gprof xtensa-lx106-elf-readelf xtensa-lx106-elf-as xtensa-lx106-elf-gcc-4.8.2 xtensa-lx106-elf-ld xtensa-lx106-elf-size xtensa-lx106-elf-cc xtensa-lx106-elf-gcc-ar xtensa-lx106-elf-ld.bfd xtensa-lx106-elf-strings xtensa-lx106-elf-c++filt xtensa-lx106-elf-gcc-nm xtensa-lx106-elf-nm xtensa-lx106-elf-strip xtensa-lx106-elf-cpp xtensa-lx106-elf-gcc-ranlib xtensa-lx106-elf-objcopy xtensa-lx106-elf-ct-ng.config xtensa-lx106-elf-gcov xtensa-lx106-elf-objdump

Sorry its hard to read. But at the folder there i build the file also doesent't exists

[SamuelGold]

Did you have g++ installed in your system? Try command: g++

[rfamp]

Yes it's installed. What else can i do?

[igrr]

The issue is that you are not using the lx106-g++ branch of crosstool-NG. https://github.com/jcmvbkbc/crosstool-NG/archive/lx106-g++.zip

Or just clone the git repository and then git checkout -b lx106-g++.

[rfamp]

Thank you it works!! But now esptool is missing ;) Cannot run program "/home/eagle/Dokumente/arduino-1.6.1/hardware/tools/esp8266/esptool Where do i have to download esptool?

[igrr]

Here's the github page: https://github.com/igrr/esptool-ck I don't have a build for linux x86, but if you make one, I can post it on the releases page for others to use. You can run make dist to build the release archive. Same goes for the linux x86 toolchain — if you tar czvf it and upload somewhere, that would also be cool.

[tytower]

Man this is a serious error issue . Its all over the net . People can't get past the compile error and this explanation is just dangerous . It needs to be fixed properly

[tytower]

I don't seem to be able to edit my comment above What I mean is getting the crosstool as suggested above is not a good thing to tell a casual user of the Arduino IDE. "The issue is that you are not using the lx106-g++ branch of crosstool-NG." So how does it get fixed in the ESP2966 hardware library that is being used by normal people? I don't want to be downloading /compiling and installing programs cause I'll end up with a bloody great mess!

[igrr]

The question was how to make this thing work on 32-bit Linux machine. The answer is outlined above. I didn't mean to suggest that this is the way that regular users should follow.

Well, the reason we don't have a version for Linux x86 is that I don't have access to 32-bit Linux server that would allow me to build the toolchain and esptool. So when someone who has access to the right system builds the toolchain and uploads it somewhere, I'll create a version of arduino for 32-bit Linux.

At this point you can either contribute to the project by building the toolchain and sharing it, or wait until someone else does that. On May 1, 2015 8:17 AM, "tytower" notifications@github.com wrote:

Clarification: I use Travis-CI for Arduino builds for Linux. They have a 64-bit environment. For the toolchain builds I use a vps from DigitalOcean. These are also 64-bit. I will try setting up a 32-bit Vagrant environment to build the toolchain. The reason I haven't done this before is that no one actually came asking for a 32-bit Linux version until last week :) On May 1, 2015 8:40 AM, "Ivan Grokhotkov" igrokhotkov@gmail.com wrote:

Good stuff - I have such a machine and can compile on it from the usual ./configure , make ,make install. Buts thats about the depth of my knowledge. I am happy to do so if you could lead me by the nose

[tytower]

I ran the configure ,make make install on my machine and got this directory . Is that of any use ?

I hav'nt got this system worked out yet to edit posts . Edit doesn't work with my browser. I attached a file to the email I sent you but I don't see it here so I don't know how to get the compiled directory you seek to you ? Hang on I see something below,nope tried dragging a tar.gz file but no go. Selected it but no go. Edit in full screen didn't work either

[igrr]

You need to run:

./bootstrap ./configure --prefix=pwd && make make make install ./ct-ng xtensa-lx106-elf ./ct-ng build tar czvf archive.tgz ./builds/xtensa-lx106-elf/

and then upload archive.tgz somewhere, wetransfer.com is fine.

Got to ./ct-ng then errors from there like so

./ct-ng xtensa-lx106-elf

bash: ./ct-ng: make: bad interpreter: No such file or directory

./ct-ng build

bash: ./ct-ng: make: bad interpreter: No such file or directory

tar czvf archive.tgz ./builds/xtensa-lx106-elf/

tar: ./builds/xtensa-lx106-elf: Cannot stat: No such file or directory tar: Exiting with failure status due to previous errors

So I'll try to put the previous gz file where you suggest . I attached it to the previous email. Where did that go ?

Mate sorry . I didn't get a link from WeTransfer It sent it to the reply email address which seems to be here . I also cloned and "make dist" as per instructions for esptool and sent it , so I have both zip files and will put them on a file holder someplace shortly. When you say "send them to me " how can I do that when you don't publish your email address or any way to get you except here? You must have set it up that way I guess

[igrr]

ivan@esp8266.com -- it's actually written in the Readme file. otherwise just copy&paste the link you got from wetransfer. On May 3, 2015 07:05, "tytower" notifications@github.com wrote:

[igrr]

@tytower I checked and it looks like Travis doesn't have 32-bit build agents currently. So we need to provision a 32-bit vagrant env for travis builds — but I haven't yet had time to do that.

[tytower]

OK Ivan Happy to help if I can

Seeing as there was nothing happening here any time soon I decided to fire up a 64 bit version of Puppy Linux called "Fatdog" and install the java , and ArduinoIDE as needed. Different processor too -Intel rather than AMD. So with other problems that took two days to get up and running and what do you think happened when compiling the ESP8266 WiFi sketch ?? Exactly the same bloody error as before !!!

I think you want to have another good hard look at this as something in your library is not right and its not just a 32 bit IDE Problem as you say it is .

[tytower]

I might also add that I commented on Sandeeps git hub page that some entries in the directory listings of his library did not look right and his response has not arrived yet and he says he got his library as a fork off yours so the same errors are probably here too

[consolacion]

got the same error on ubuntu32 bit, eventhough the file it says it is missing is clearly present. Tried it on Linux 64 as well... indeed, same problem

[igrr]

The toolchain is 64-bit, but i'm no linux guru — perhaps it runs on some 64-bit Linux systems but not on others.

@consolacion Could you please try to run this from command line? xtensa-lx106-elf-g++ --version (appending the correct path before xtensa-lx106-elf-g++) and see if it runs from the command line?

[consolacion]

it says 'command not found, eventhough I see the file right in front of me

[igrr]

can you run readelf -l xtensa-lx106-elf-g++ to see which library is missing?

[consolacion]

friend had the same problem on windows 7, 32 bits

Round and round skirting the issue . You need to look again . Here is the full error message trying to run the Arduino IDE 1.6.4 on 32 bit version

./arduino

Now this may be your library or not . I don't have the experience to tell but I want to get on and run this properly using your library . Can you help at all ?

[igrr]

1.6.4? Where did you download it from — Arduino.cc website? This fork is still 1.6.1.

[tytower]

Of course-Users like myself do not know the assumptions you make or use, we just want the library to run . The latest Arduino IDE is 1.6.4 and I want to stay up to date . So does it run on this or do you intend to get it running on this IDE . Or perhaps not . This version seems to run on IDE 1.6.1 and I am using a special copy so I can move past you. The fork I use is to eat with.

The latest board manager package has 32-bit Linux toolchain included (Readme has been updated with installation instructions).

[consolacion]

That seems to be working Ivan, at least it compiles without errors :-) Great. Thanks. Quite some work you have done. Installation through the boardmanager was a breeze! Well done

[consolacion]

btw... it was running smooth already on my 64 bits windows 8.1

Kudos to @majenkotech for building the 32-bit linux toolchain! :+1:

Hi Ivan , I am having trouble getting realistic readings from a pressure sensor BMP180 on my ESP8266 ESP12 boards.

I get this

The temp should be about 21.5 C and the pressure about 950 mb. The same device gives good readings on an Arduino ATMega328P. I have played with the Wire.setClock() function settings tried 40000 , 100000,400000. All without difference. Here is my code if needed .

Can you suggest a possible fix?
