imagesource error in april_tk

GoogleCodeExporter commented 9 years ago

When I do: 
rosrun april_tk execute april.jcam.JCamView

Output:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no imagesource in 
java.library.path

Using the driver on Ubuntu 12.04 LTS.

I cannot reproduce this error. I think something in the build process has 
failed without informing the user.

Can you print the output of the following command:
rosls april_tk/lib

If the above results in no such file or directory, then can you print the 
output of the following command:
rosmake april

There was no directory called april_tk/lib so i'm pasting the required output. 
I even checked the build log in the /.ros folder and the build_failures.txt 
file is blank!

I'll check the directory name again tomorrow. Can you print the output
of this file:
/home/dev/.ros/rosmake/rosmake_output-20121023-125208/lcm/build_output.log

Also, are you using a Mac for this (given your machine name)? I think
some of the system dependencies may be missing.

Attached is the file..

And yes I am using a mac..though I installed all the opencv dependencies before 
doing the rosmake..can you pinpoint which dependency I am missing?

Thank you very much for your time Piyush...

this is the output of april_tk 's log..

build_output.log

GoogleCodeExporter commented 9 years ago

So based on the jni.h error in the april_tk package's log, I saw your 
openjdk-6-patch.diff file, and noticed that it expects the jni.h file to live 
in the /usr/lib/jvm/java-6-openjdk, but for some reason on my laptop, that 
folder is empty and jni.h lives in /usr/lib/jvm/java-6-openjdk-i136. Changing 
either the .diff file or the actual image_source_jni.c file doesn't help as 
they are downloaded fresh from git for every make..How can I change the search 
path for the jni.h file?

Original comment by devendra...@gmail.com on 23 Oct 2012 at 10:20

GoogleCodeExporter commented 9 years ago

Ok, so this is because the CMakelists supplied by the April toolkit is
not really cross-platform, it relies on jni.h being at a specific
location (expecting the OS to be Ubuntu).

There is a bug in the ROS pacakge that when the gradle wrapper fails,
it does not return an incorrect exit code -- consequently the build
passes. I will see if I can fix this somehow. This would have saved a
bit of time for both of us.

Note: openjdk-6-patch.diff is not downloaded afresh ever ytime you run
make in the package. I would recommend the following:
1) Build the package as normal using make (let it fail)
2) Go into build/april and modify the CMakeLists.txt with the jni.h
file location until you can get it to work.
3) Generate the diff file and send it over to me, and I will tag a
separate branch for osx. For the time being, replace the
openjdk-6-patch.diff with the diff you generated.
4) Submit a separate enhancement ticket with the diff.

I don't have access to too many macs, so it will be difficult for me
to test this out, but I will try to. Keep in mind that the April
toolkit build is only meant for Ubuntu. This might be the first of
your problems...

Sorry for being vague, but i'm running the Ubuntu OS on a Mac. I'm running it 
on a separate bootcamp partition, so there should be no issues because of that.

So I changed the makefile in stacks/april/april_tk/build/april/java/jni/jcam, 
but on every make it is restored to the original file on the respository..I'm 
unfortunately not well versed with Makefile, so please tell me how I should 
stop it from acquiring the files afresh on every make?

Again, thank you very much for your time, I really appreciate it.

Ah understood. I suspect this is an i386 bug then. I only have 64 bit machines.

Once you change the files, generate the diff using git diff. Replace
the patch file with this diff. Then use make. The patch will be
applied once the code is downloaded.

I changes the .diff file manually with the correct paths, and everything is 
working fine now. Thank you very much Piyush!

Can you send me the diff file? I will try and fix the i386 issue.
