Re: [blfs-support] Build v4l-utils-1.14.2 error, missing glx.h.

Dear Thanos,

I have built and installed mesa, but there is still no GL/glx.h. Do you have glx.h and glext.h after installation of mesa?

Yours sincerely,

Lei

Hi everyone,

I am building Gnome from scratch, and this time I stuck at building v4l-utils-1.14.2 (sorry for Chinese character, but I still think you can understand where are the problem lines):

make[3]: 进入目录“/home/neil/gnome/v4l-utils-1.14.2/contrib/test”

  CC v4l2gl.o

v4l2gl.c:28:10: 致命错误：GL/glx.h：没有那个文件或目录

 #include <GL/glx.h>

          ^~~~~~~~~~

编译中断。

make[3]: *** [Makefile:599：v4l2gl.o] 错误 1

make[3]: 离开目录“/home/neil/gnome/v4l-utils-1.14.2/contrib/test”

make: *** [Makefile:509：all] 错误 2

I only digest the part of log related with my problem. I think this is caused by missing GL/glx.h. Before I come to this phase, I download <GL/glext.h> and  <KHR/khrplatform.h>  from the khronos.org website to overcome the same problems like missing glx.h. 

My question is which LFS package containing these gl*.h headers, because I know to solve these problems by downloading headers is not the correct solution.

Yours sincerely,

Lei
