All,

On 2015-02-08 08:30 +0100, Thomas Petazzoni spake thusly:

I had a look at that one. That's strange...

checking EGL/egl.h usability... no
checking EGL/egl.h presence... no
checking for EGL/egl.h... no
checking whether to enable EGL support... no
checking GLES2/gl2.h usability... yes
checking GLES2/gl2.h presence... yes
checking for GLES2/gl2.h... yes
checking whether to use OpenGL ES 2 support... configure: error: Cannot
enable OpenGL ES 2 support without EGL

So I tried reproducing it here, and it fails all the same. SO I had a
look at config.log, and saw this:

    configure:20368: /home/ymorin/dev/buildroot/O/host/usr/bin/arm-linux-gcc
    -c -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os
    -Wno-cast-align -Wno-sign-compare -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
    -D_FILE_OFFSET_BITS=64 conftest.c >&5
    In file included from /home/ymorin/dev/buildroot/O/host/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include/interface/vcos/vcos_assert.h:149:0,

                     from /home/ymorin/dev/buildroot/O/host/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include/interface/vmcs_host/vc_dispmanx.h:33,
                     from /home/ymorin/dev/buildroot/O/host/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include/EGL/eglplatform.h:110,
                     from /home/ymorin/dev/buildroot/O/host/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include/EGL/egl.h:36,
                     from conftest.c:64:
    /home/ymorin/dev/buildroot/O/host/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include/interface/vcos/vcos_types.h:38:33:
    fatal error: vcos_platform_types.h: No such file or directory
     #include "vcos_platform_types.h"
                                     ^
    compilation terminated.

So, whats weird is that vcos_platform_types.h is in:
    staging/usr/include/interface/vcos/pthreads/vcos_platform_types.h

which we correctly set in egl.pc:

    prefix=/usr
    exec_prefix=${prefix}
    libdir=${exec_prefix}/lib
    includedir=${prefix}/include

    Name: egl
    Description: RasberryPi implementation of EGL
    Version: 10
    Libs: -L${libdir} -lEGL -lGLESv2 -lbcm_host -lvchostif
    Cflags: -I${includedir}/ -I${includedir}/interface/vcos/pthreads/ \
            -I${includedir}/interface/vmcs_host/linux/

But then, if one looks at the command line, the -I path to vcos_platform_types.h
is not present, so it is not a wonder that it does not find it.

However, there is no specific -I paths at all either, so it is in turn a
wonder it finds the other vcos headers:
    sysroot/usr/include/interface/vmcs_host/vc_dispmanx.h
    sysroot/usr/include/interface/vcos/vcos.h
    sysroot/usr/include/interface/vcos/vcos_assert.h

And even for the EGL headers:
    sysroot/usr/include/EGL/egl.h
    sysroot/usr/include/EGL/eglplatform.h

So, I'm not sure what happens here... :-(

Investigation in progress...

Regards,
Yann E. MORIN.
