OS X Compiling support

[harshakasi]

Hello,

I have downloaded the latest pypylon Release 1.4.0 package. Tried my best to build the code on Mac OSx and failed. Following is the output I get from executing this command: sudo python setup.py develop

The result of this command was the following:

fatal: not a git repository (or any of the parent directories): .git

Hi folks,

My colleague @sparshturaga was able to help me out just by browsing to the part in setup.py --> under the class BuildSupportMacOS(BuildSupport):

1. adjusting the path of my pylon.framework path related strings by modifying
   class BuildSupportMacOS(BuildSupport):

   FrameworkPath = '/Library/Frameworks/'

   FrameworkName = 'pylon.framework'

   PylonConfig = os.path.join(FrameworkPath, FrameworkName, 'Versions/A/Resources/Tools/pylon-config.sh')

2. and just below that adding compiler flags accordingly:

ExtraCompileArgs = [
'-Wno-unknown-pragmas',
'-fPIC',
'-g0',
'-Wall',
'-O3',
'-Wno-switch',
'-stdlib=libc++'
]

ExtraLinkArgs = [
                '-g0',
                '-Wl,-rpath,@loader_path',
                '-Wl,-framework,pylon',
                '-F' + FrameworkPath,
                **'-stdlib=libc++'**
                ]

Voila! Works like magic. Thanks for contributing @sparshturaga one and all folks.

[Knoose]

@nimamox, I was able to built it on my Mac and have been using it. I used the following branch and just followed the instructions in the Readme. https://github.com/basler/pypylon/tree/feature/python37

I had to modify a few lines of code but it does work.

Edit:
The feature/python37 branch does not exist anymore. Please use version 1.4.0 or greater. It worked without any modification.

[rarunsrivatsan]

Thank you very much. That worked!

[basler-oss]

No, we do not plan to add support for macOS. However - as we release the pypylon also in source you might try to port pypylon to macOS by yourself. Any input/feedback concerning this approach would be highly welcome :-)

[lauritk]

Hi, thank you for fast reply. I tried, but had some problems with OS X permissions and anaconda python 3.6 with the OS X's Library folder where all the libs are. Will try it again after doing some research with swig and OS X compiling.

[basler-oss]

Great - keep us posted about your progress :-)

[matt-phair]

I've been trying to nail this down and am running into some problems.

• BinPath and the conditional in make() are missing macosx-10.9-x86_64. I've added it.
• call_pylon_config() ends up putting a -n at the front of the stuff it returns. I've manually stripped that out.
• The PYLON_ROOT isn't defined correctly. I couldn't find it on OSX after installing Pylon, but I found them packaged up in the osx download
• -Wl,--enable-new-dtags isn't accepted by osx's ld. I've removed it from the ExtraLinkArgs
• -Wl,-E also isn't accepted by ld. I've removed it after the self.call_pylon_config("--libs") call

After these changes, pip install . seems to work correctly. However when call from pypylon import pylon it errors out:

>>> from pypylon import pylon

Thoughts?

[matt-phair]

I'm starting to think that maybe the issue is that the latest OSX install for the Pylon SDK is 5.0.5 but the latest for other platforms is 5.0.12.

@basler-oss Do you think this is causing the run-time issues? If so, can you provide a later osx build for the SDK?

[stefanklug]

@matt-phair It is pretty unlikely that the version (5.0.5) is causing these problems. I suspect your way of linking the pylon framework might be a problem here. I didn't have a deeper look, but did you link pylon as shown in the OSX samples using the -framework switch?
If you can provide a branch with your changes in the setup.py maybe I can have a look at it.

[matt-phair]

@stefanklug Still working on getting something non-messy to put up so others can see. However, during the refactor I found that I was setting PylonConfig in setup.py to be an executable built on a different platform. The only pylon-config executable I found after the OSX installation was in /Library/Frameworks/pylon.framework/Versions/A/Resources/Tools/pylon-config and that doesn't come with the commands necessary for the setup.py script to run.

$ /Library/Frameworks/pylon.framework/Versions/A/Resources/Tools/pylon-config --libdir
Unknown command --libdir
Usage: /Library/Frameworks/pylon.framework/Versions/A/Resources/Tools/pylon-config <command>... [library]

    pylon               the pylon C++ library (default)

    --version-minor     Prints the minor version
    --version-subminor  Prints the subminor version
    --version-build     Prints the build version

[matt-phair]

I used the linux pylon-config results to hard-code some of the paths for OSX. I also had to change all of the %include <pylon/*> lines in the *.i files to be %include <*> but now it compiles and imports. However, it doesn't find a camera.

>>> camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/pypylon/pylon.py", line 1025, in CreateFirstDevice
    return _pylon.TlFactory_CreateFirstDevice(self, *args)
_genicam.RuntimeException: No device is available or no device contains the provided device info properties. : RuntimeException thrown (file 'TlFactory.cpp', line 917)

If I run the pylon viewer app the camera shows up.

[matt-phair]

And with that search query in mind, I found this:

mabl/PyPylon#18 (comment)

which works great. Looks like their conclusion is that @basler-oss needs to update their OSX release.

[matt-phair]

For the lazy:

Before you execute python call this:

export LD_LIBRARY_PATH=/Library/Frameworks/pylon.framework/Libraries

[matt-phair]

I created a pull request for this: #13 but it needs some work before merging.

[matt-phair]

@stefanklug You mentioned maybe being able to look at the code I'm using. I'm not sure how to finish this off without changing the .i files. If you can have a look and maybe lead me to the right answer, that would be great. #13

[stefanklug]

The issue with the .i files is that swig doesn't support OS X frameworks. On OS X if you link to the framework "pylon" an include <pylon/something.h> automatically resolves to /path/to/pylon.framework/Headers/something.h
See also http://swig.10945.n7.nabble.com/SWIG-and-Mac-OSX-frameworks-td11602.html

There is no clean way around this problem without fixing swig. A workaround (not tested) might be to recreate that structure with symlinks. Something like:

mkdir <build_dir>/includes
cd <build_dir>/includes
ln -s /path/to/pylon.framework/Headers pylon
#call swig with -I<build_dir>/includes

[matt-phair]

@stefanklug Thank! That worked and I've updated #13 to not have all of the .i file changes.

[lauritk]

Great work @matt-phair! I will test this soon as possible. Something wrong with the merge?

[matt-phair]

Something wrong with the merge?

Not sure what you mean. The PR can merge cleanly. It's failing one check, but all of the PRs on the repo are failing that check, even ones that only change the help file. I'm not sure what that check is or how to fix it.

[stefanklug]

The PR looks mostly good to me. Don't worry about the failing checks. The history needs some cleanup though and it should be rabased.
One question remains: Is the LD_LIBRARY_PATH issue still there? This should be fixed before merging the changes. According to one of our OS X devs, the libs should work fine. I suspect a rpath issue in the _pylon.so and the _genicam.so
See http://jorgen.tjer.no/post/2014/05/20/dt-rpath-ld-and-at-rpath-dyld/ for more details.

[matt-phair]

One question remains: Is the LD_LIBRARY_PATH issue still there?

Yeah, still there.

[matt-phair]

@stefanklug I've rebased. Its the first time I've worked outside of the standard branch and merge paradigm so I'm not sure if what I did was correct. I ended up rebasing and squashing onto my forked master and then making a new PR from that. You can see it here #29

[RamoramaInteractive]

I always receive the error

Traceback (most recent call last):
   File "C:/Users/rwilhelm/Desktop/pypylon/samples/grabmultiplecameras.py", line 56, in <module>
     for i, cam in enumerate(cameras):

     if args[0] >= self.GetSize():
 NameError: name 'args' is not defined

even if I copy and paste the entire code for grabbing with multiple cameras.

Why is it not working?

I'm using Anaconda with Python 3.5 on Windows 7.

[matt-phair]

@AlanHorman This is the issue specifically for compiling on OSX. Maybe you meant to start a new issue?

[nimamox]

Has there been any updates on using PyPylon on macOS?

[gmnamra]

The link is no longer valid. And I do not see a binary wheel for maxOS ( OS X ). Any pointers ?

[Knoose]

The master branch now supports the ability to build a binary wheel for macOSX. This was added in Release 1.4.0 and can be found from the release notes (https://github.com/Basler/pypylon/releases).

What could be going wrong ?
Please help

[harshakasi]

@nimamox, I was able to built it on my Mac and have been using it. I used the following branch and just followed the instructions in the Readme. https://github.com/basler/pypylon/tree/feature/python37

I had to modify a few lines of code but it does work.

@Knoose Would you stil recommend to use this build ?

[gmnamra]

Sorry, I made the changes as suggested above, but it still throws the following error:
clang: error: invalid deployment target for -stdlib=libc++ (requires OS X 10.7 or later)
error: command 'gcc' failed with exit status 1

I am currently running it in OS X 10.14.5, so I dont know why it is an issue. Can someone help me?

[Knoose]

Do you have the XCode Developer Tools installed to your machine?

[rarunsrivatsan]

Yes I have Xcode developers tools installed

[Knoose]

Can you follow the instructions found under the Installation from Source heading in the readme? Make sure you have PCRE and SWIG installed. See if that works for you. If it does, then you can build the wheel file by specifying python setup.py bdist_wheel . This requires wheel to be installed to your python environment.

[Knoose]

I'm glad that worked :)

Hi, I've done all of this but am still having trouble building on macOS. I'm running OS Sierra version 10.12.6. I keep getting the following error:

error: can't copy 'pypylon/pylon.framework/Versions/A/_CodeSignature': doesn't exist or not a regular file

Any ideas?

Hello,
I have downloaded the latest pypylon Release 1.4.0 package. Tried my best to build the code on Mac OSx and failed. Following is the output I get from executing this command: sudo python setup.py develop
The result of this command was the following:

Hi folks,

My colleague @sparshturaga was able to help me out just by browsing to the part in setup.py --> under the class BuildSupportMacOS(BuildSupport):

1. adjusting the path of my pylon.framework path related strings by modifying
   class BuildSupportMacOS(BuildSupport):
   FrameworkPath = '/Library/Frameworks/'
   FrameworkName = 'pylon.framework'
   PylonConfig = os.path.join(FrameworkPath, FrameworkName, 'Versions/A/Resources/Tools/pylon-config.sh')
2. and just below that adding compiler flags accordingly:

ExtraCompileArgs = [
'-Wno-unknown-pragmas',
'-fPIC',
'-g0',
'-Wall',
'-O3',
'-Wno-switch',
'-stdlib=libc++'
]

ExtraLinkArgs = [
                '-g0',
                '-Wl,-rpath,@loader_path',
                '-Wl,-framework,pylon',
                '-F' + FrameworkPath,
                **'-stdlib=libc++'**
                ]

Voila! Works like magic. Thanks for contributing @sparshturaga one and all folks.

I made these changes except for

ExtraCompileArgs = [
'-Wno-unknown-pragmas',
'-fPIC',
'-g0',
'-Wall',
'-O3',
'-Wno-switch',
'-stdlib=libc++'
]

ExtraLinkArgs = [
                '-g0',
                '-Wl,-rpath,@loader_path',
                '-Wl,-framework,pylon',
                '-F' + FrameworkPath,
                **'-stdlib=libc++'**
                ]

at everything installed ok

Your modification was required on pypylon master?
What OS version ?
Can you provide a pull request ?

I am running macOS 10.15.7.

I have only modified the following entries in setup.py

FrameworkPath = '/Library/Frameworks/'
FrameworkName = 'pylon.framework'
PylonConfig = os.path.join(FrameworkPath, FrameworkName, 'Versions/A/Resources/Tools/pylon-config.sh')

With the above modification to setup.py I can install pypylon without error-message on mac os 11.1.
But apon import, I get an error:
#>>> from pypylon import pylon
Traceback (most recent call last):

Using pylon v5

Anybody an idea? Thx.

P.S.: Same on Version 1.54

Beginning with release 1.7.1 we have binary releases on all platforms, that you can install via pip.

update your pip version before by calling python -m pip install --upgrade pip
