Issues building the native modules

[rcarjan]

@castiel520 I have managed to solve this issue by building my own panda3d, and changing the build script a little.

What I did was edit the makepanda.py script, replacing both instances of "-pthread" with "-lpthread": here and here
It seems that when compiling with -pthread won't work, i'm not sure why.

Regarding this error:
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock
I'm still not sure what caused it, but it seems to compile and work OK even with this message popping up every few seconds, so I guess it's not that important.

Could you state which exact version of Panda you have? Knowing what drivers you have would help, too.

[rcarjan]

Regarding the panda version, it's the latest version to download as of today: panda3d1.10_1.10.0-dev1106-zesty_amd64

As for the drivers, I have only installed the nvidia proprietary drivers:

@rdb I've met the same error under ubuntu 16.04 with native build

[castiel520]

@rcarjan thanks for you reply!

unfortunately your solution does not work for me, i still got the same error.
here is what I did:

• uninstall the prebuild version of panda3d and get from latest master, replacing both instances of "-pthread" with "-lpthread" as you suggested
• make panda3d*.deb and install it
• run setup.py still got the same issue.

have you change any build script in RenderPipeline?
thanks again!

[rcarjan]

@castiel520 No, sorry, this is the only change I have made.
Are you using python 2 or 3?
Have you installed all necessary dependencies?

[castiel520]

@rcarjan hi, I am using python 2, and I have installed all necessary dependencies.

today i tried re-build panda3d and render-pipeline yet still got the same error. But really thanks for your help:)

[mpbagot]

I had the same problem, you have to change the read permissions of the files in /usr/include/panda3d. By default, the interrogate script cant read them and it causes the build to fail. Either run chmod or chown on the folders contents and re-run the render pipeline build. That should fix it.

Hope that helps.
