[ptxdist] How to override files from another package

[Guillermo Rodriguez Garcia]

Hi all,

Is there a way for a ptxdist package to override files from another package?
For example something similar to this:

https://lists.linaro.org/pipermail/openembedded/2016-June/000031.html

I tried to create a package which depends on MESALIB (so that
mesalib's targetinstall rule runs first), and then simply overwrite
the files, but this fails when the package is generated, because there
are multiple packages trying to provide the same files.

 BR,

It's not possible. What exactly are you trying to achieve? Which files do
you want to overwrite?

As in the post from the ML above -- I am trying to overwrite the
generic GL libraries provided by Mesa and replace them with
vendor-provided binaries.

A quick way is to copy mesa rules into your BSP and modify them not to copy
libraries you are not interested in to the target.

Yes, that's what I am doing now. I was just wondering if there is a cleaner way.

Then you should not install mesa at all.

Not all libraries are replaced.

Also mesa is selected by other packages (such as weston), so if I
wanted to skip mesa I would need to patch those as well..

Which libraries do you want replace? I assume libgbm from Mesa remains but
libGL* are replaced? And weston still works that way?

You don't want to do that. Etnaviv supports your GPU just fine :-)

I don't know. I started a discussion about this with someone some time
ago; we were talking about this and other topics (upstream vs vendor
kernel, u-boot vs barebox, vendor GPU drivers vs etnaviv, NAND vs
eMMC...) but then I suddenly stopped getting answers :-)

That was probably that ... "Robert". He is known for having a pretty
well filled mailbox. I'll poke him to take care of you! :^)
