ffmpeg compilation error #8

Closed RoncoCo closed 6 years ago

RoncoCo commented 6 years ago

Hi,

Following your instructions on how to build ffmpeg I have encountered an error while running the ./configure command I am getting the following error.

./configure --enable-libx264 --enable-gpl --enable-opengl --enable-filter=gltransition --extra-libs='-

lGLEW -lglfw' gcc is unable to create an executable file. If gcc is a cross-compiler, use the --enable-cross-compile option. Only do this if you know what cross compiling means. C compiler test failed.

If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.

I am running the build from Windows os, my c compiler is configured and present on PATH, I am able to run ./configure successfully without the parameters.

hmm, your libs= command seems to contain some newlines. i'd try it making sure the output prints out correctly, without any newlines

Otherwise, maybe double-check the windows ffmpeg compilation instructions. It seems like gcc isn't being invoked properly, so make sure you follow the official ffmpeg guide to compiling for your platform before trying to compile this slightly modified version.

I have looked into the ffmpeg compilation instructions and when I try to run them the compilation is successful, Also typed the entire params for the configure but I still get the same error,

Could it be that I am missing something that need to be present in the environment variables? or any other configuration issue?

transitive-bullshit commented 6 years ago

I'm really not sure, as I don't have a Windows machine to test with.

Are you sure that ./configure and make both build successfully for you with a vanilla checkout of ffmpeg?

You might also want to try searching for your error.

If you're using Ubuntu 17.10 or something like this, try to check if you have already installed libglew-dev and libglfw3-dev, or run apt install libglew-dev libglfw3-dev directly, before ./configure ....

try to use --extra-libs='-lGLEW -lEGL' instead of --extra-libs='-lGLEW -lglfw' when compiling with configure and make
