Zoltán Böszörményi commented on a discussion on src/meson.build:
152 152
libraries : libgl,
153 153
libraries_private : gl_priv_libs,
154 154
requires_private : gl_priv_reqs,
155
- variables : ['glx_tls=@0@...ormat(use_elf_tls ? 'yes' : 'no')],
155
+ variables : ['glx_tls=@0@...ormat('yes')],
156 156
)
I don't think it's a good idea to make ELF_TLS unconditionally true.
Yocto allows choosing the LIBC at least between GLIBC and MUSL, and Mesa
built with TLS crashes under MUSL.
See this patch:
https://git.openembedded.org/openembedded-core/tree/meta/recipes-graphics/mesa/files/0002-meson.build-make-TLS-ELF-optional.patch
and here TLS is only enabled for GLIBC:
https://git.openembedded.org/openembedded-core/tree/meta/recipes-graphics/mesa/mesa.inc#n92
So I am confused. What's the situation about ELF-TLS support in musl?
Is that still broken now?
