FFmpeg build not successfully

[crdesai25]

try to build ffmpeg with gt-transition buy got following error.
Undefined symbols for architecture x86_64: "_glfwCreateWindow", referenced from: _setup_gl in libavfilter.a(vf_gltransition.o) "_glfwDestroyWindow", referenced from: _uninit in libavfilter.a(vf_gltransition.o) "_glfwInit", referenced from: _init in libavfilter.a(vf_gltransition.o) "_glfwMakeContextCurrent", referenced from: _setup_gl in libavfilter.a(vf_gltransition.o) _blend_frame in libavfilter.a(vf_gltransition.o) "_glfwWindowHint", referenced from: _setup_gl in libavfilter.a(vf_gltransition.o) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [ffmpeg_g] Error 1

want to make a build for mac OS and android.
Is there any better way to make a build or get inbuild gl-transition ffmpeg?

The error looks like glfw isn't being found. Make sure it's installed properly.

Mac OS should build fine as it's been thoroughly tested. Not sure about Android.

I'm having a similar issue in 'make' on High Sierra 10.13.5:

Undefined symbols for architecture x86_64:
  "_glfwCreateWindow", referenced from:
      _setup_gl in libavfilter.a(vf_gltransition.o)
  "_glfwDestroyWindow", referenced from:

ld: symbol(s) not found for architecture x86_64

I know glfw is installed correctly.

This is from the configure file:

385 --extra-ldsoflags=ELDFLAGS add ELDFLAGS to LDSOFLAGS [$LDSOFLAGS]
386 --extra-libs=ELIBS add ELIBS [$ELIBS]
387 --extra-libs='-lGLEW -lglfw'
388 --extra-version=STRING version string suffix []

I'm manually editing the file to insert the line --extra-libs='-lGLEW -lglfw'.

@NCPatrick
hi
please use --extra-libs='-lGLEW -lglfw'. when ./configure.
edit the configure file at that line only affect the output of ./configure --help
