Description sheepdestroyer 2016-03-10 15:15:45 UTC

On fedora 23 64b, Intel HD3000 (SNB)

I used to be able to run Steam on my self built i686 git Mesa driver, but not recently (few months).

I tried to build the simplest Mesa with default options, copying those of official Fedora (copied from koji, is there a better way?), then about any mix of FLAGS and arguments.

Steam runs on official Fedora Mesa builds but not on self built one anymore.
Reinstalling distro drivers does permit to run Steam again.

It's not a generic pb with my build config though, as any other i686 GL apps run just fine.

What is the best way to compile an equivalent Mesa to the one available in repo?
What changed in Fedora that self built drivers (with default options) used to work but not anymore?

I did try with both STEAM_RUNTIME=0 and STEAM_RUNTIME=1, to same results.

Analyze of the crash dump gave libcrypto.so.1.0.2g related error. Someone helpful guessed that "this is from the removal of ssl2 which happened in openssl 1.0.2f -> 1.0.2g"

So I rebuilt mesa with --with-sha1=libnettle (instead of libcrypto) and that now works.

Who is to blame?

Doesn't sound like us.
