mesa-git build script for latest panfrost

[xmixahlx]

with the pending release of v20 the "20.0" branch has been created. those trying to avoid the bleeding edge can add "--branch=20.0" to the git clone command.

Thanks xmixahlx for publishing this script. It is really helpful.

I tweaked/prettified it a little bit and placed it on my github drive.

I worked my way through a number of the missing dependencies, but I'm stuck on this one:

Code:

Run-time dependency xcb-dri2 found: NO (tried pkgconfig and cmake)

meson.build:1644:4: ERROR: Dependency "xcb-dri2" not found, tried pkgconfig and cmake

dpkg -S xcb-dri2 returns:

Code:

libxcb-dri2-0:arm64: /usr/share/doc/libxcb-dri2-0/changelog.Debian.gz
libxcb-dri2-0:arm64: /usr/share/doc/libxcb-dri2-0
libxcb-dri2-0:arm64: /usr/lib/aarch64-linux-gnu/libxcb-dri2.so.0.0.0
libxcb-dri2-0:arm64: /usr/share/doc/libxcb-dri2-0/copyright
libxcb-dri2-0:arm64: /usr/lib/aarch64-linux-gnu/libxcb-dri2.so.0
libxcb-dri2-0:arm64: /usr/share/doc/libxcb-dri2-0/changelog.gz

When I try to install libxcb-dri2-0 with apt, it looks like it's installed?

Code:

libxcb-dri2-0 is already the newest version (1.14-2).

I'm not sure where to go from here to meet this dependency?  Some previous posts mentioned meta packages that might include this, but I didn't see the package names.

Any pointers appreciated, thanks!

You probably need the libxcb-dri2-0-dev package. On my system dpkg -S xcb-dri2 reports in part:

Code:

libxcb-dri2-0:arm64: /usr/lib/aarch64-linux-gnu/libxcb-dri2.so.0
libxcb-dri2-0-dev:arm64: /usr/lib/aarch64-linux-gnu/pkgconfig/xcb-dri2.pc

Note the .pc file, which should make the library visible to pkgconfig. In general you need the corresponding -dev package for any library your compiling software to use.

Thank-you rillian, that got things moving again!

Glad to hear it worked!

fyi mesa_master is going through considerable changes and i've encountered graphics issues. stepping down to branch 20.1 has solved those for me.

however, there is considerable activity in panfrost, so I expect to test in another week.

if you are using debian, 20.0.7 is in unstable and 20.1.0 is in experiemental. if you want to play with GLES3 use experimental or 20.1 git branch, or roll the dice with master.

updated the first post

the panfrost restructure in mesa-git has finished and is working great again.
