Hi. I remember that building via autotools is not a priority but I guess, it still should work.
Here is a command for configuring:
>./autogen.sh --with-gallium-drivers="" --with-dri-drivers=i965 --prefix=/home/den/mesa64/mesa_19.0.0last/

For me it was broken after this commit:

den@den-HP-ZBook-14u-G4:~/repositories/mesa$ git bisect bad621b0fa8922ade0a8122b868177308e65e6d3595 is the first bad commit
commit 621b0fa8922ade0a8122b868177308e65e6d3595

    egl: Improve the debugging of gbm format matching in DRI configs.
    
    Previously the debug would be:
    
    libEGL debug: No DRI config supports native format 0x20203852
    libEGL debug: No DRI config supports native format 0x38385247
    
    but
    
    libEGL debug: No DRI config supports native format R8
    libEGL debug: No DRI config supports native format GR88
    
    is a lot easier to understand.

Haven't any ideas, what went wrong with this commit, but after it I can build mesa, but can't install (error below):


/home/den/repositories/mesa/src/egl/drivers/dri2/platform_drm.c:668: undefined reference to `gbm_format_get_name'
collect2: error: ld returned 1 exit status
libtool:   error: error: relink 'libEGL.la' with the above command before installing it
Makefile:1030: recipe for target 'install-libLTLIBRARIES' failed
make[5]: *** [install-libLTLIBRARIES] Error 1


upd - with meson build works fine.
uupd - my configuration:
ubuntu 16.04
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.10) 5.4.0 20160609
GNU ld (GNU Binutils for Ubuntu) 2.26.1
kernel 4.17.0-041700-generic

Interesting that on another 16.04 ubuntu build/install works fine. Similar issue was written in related bug (for vulkan).

Appreciate any help or suggestions.
