Building on Mac OSX 10.12.6 fails due to missing endian.h include #2205

Closed LukeKeywalker closed 4 years ago

LukeKeywalker commented 4 years ago

Expected Behavior

Running cmake would build OBS

Current Behavior

When running cmake it fails with an error specified in the build/CMakeFiles/CMakeError.log:

Building C object CMakeFiles/cmTC_f5539.dir/HAVE_ENDIAN_H.c.o
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc   -Wall -Wextra -Wvla -Wno-unused-function -Werror-implicit-function-declaration -Wno-missing-braces -Wno-missing-field-i

Steps to Reproduce

  1. Follow the build guide
  2. Run cmake .. && make
  3. See error in the CMakeError.log

This sounds like the Xcode compiler tool chain is not correctly/completely installed. More specifically you may need the Xcode command line utilities installed.

Can you try running xcode-select --install in a terminal and see if it changes anything?

LukeKeywalker commented 4 years ago

Unfortunatelly it's not that:

$ xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

I have used tool chain before and updated it prior to building. I worked around first error by symlinking /usr/include/machine/endian.h to /usr/local/include/endian.h, but then many errors like these follow:

Please provide your actual cmake log instead of picking out what you think might be the error from the error log.

--- edit --- By this i mean the entire log, not snippets. And not CMakeError.log

Sure @kkartaltepe, thank you for looking into it . Now I see that it complains about some unset variables, although I am not sure what it means. Here is the log:

It looks like you have modified the cmake configuration locally and broken it.

-- edit -- Or your cmake install is broken as the error suggests.

Is not a part of our build on the macos platforms that I can see. (the CI build)

kkartaltepe commented 4 years ago

You can try with -DDISABLE_PYTHON=1 and see if that fixes your issue perhaps. But I dont believe that is running at the point where it fails.

LukeKeywalker commented 4 years ago

Right... I jumped straight into adding source of obs-ffmpeg-encoder that I want to eventually modify, and was messing around with python versions. I should have tried building vanilla version first. Thanks for pointing that out.
