Hello,

I am sorry I'm not good at English.

I tried to build obs-studio in my MacBook pro (OSX 10.9.5)
I followed the instruction in INSTALL document.

However, when I run 'make', it fails with following error message.

Code: 
[  0%] Built target glad

I guess (from functions' names) that it is related with libbz2, but
I don't know how I can modify build process using cmake system.

Any help would be appreciated.

Seems to be an issue with your FFmpeg build, at least I'm guessing. OBS apparently can't link to it. It's difficult for me to help otherwise; I wouldn't recommend attempting to compile the project unless you have experience compiling projects in general. It's not a trivial task.

Hello, Jim.

Thank you for your reply.

At first, I just hoped this problem could be solved by modifying Makefile like, for example, inserting "LDLIBS = -lbz2" line.
But this project includes many directories, files and metafiles for build process. It's using CMakefile and I'm not familiar with it. I can't find even which target of all targets are causing this problem.

Could you give me any other hint about where I have to look into? I've installed ffmpeg-2.6.1 from source.

I can't really do it without building it for you; I also built FFmpeg from source. Are you trying to add extra features to FFmpeg or are you just using core FFmpeg? You don't really need anything other than core FFmpeg for it to build properly.

Is the FFmpeg build a shared build? Maybe it's static. These errors look like something that would come from a statically built ffmpeg. It has to be shared.

Hello gypark & Jim

You are able to resolve this issue. Am also facing the same error?

Thanks

Is your issue that you're trying to build the current version of OBS on a five year old version of MacOS? Because that probably would not work. I certainly doubt anyone is still testing current versions against Mavericks.

Hello Narcogen,

Am able to resolve it by making shared build. My motive it to get very low latency in local network like ~150 to 200ms with MAC & Windows. Can you please help me?

Thanks
