'yes' : 'no')], 155 + variables : ['glx_tls=@0@'.format('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: <a href="https://git.openembedded.org/openembedded-core/tree/meta/recipes-graphics/mesa/files/0002-meson.build-make-TLS-ELF-optional.patch">https://git.openembedded.org/openembedded-core/tree/meta/recipes-graphics/mesa/files/0002-meson.build-make-TLS-ELF-optional.patch</a> and here TLS is only enabled for GLIBC: <a href="https://git.openembedded.org/openembedded-core/tree/meta/recipes-graphics/mesa/mesa.inc#n92">https://git.openembedded.org/openembedded-core/tree/meta/recipes-graphics/mesa/mesa.inc#n92</a> So I am confused. What's the situation about ELF-TLS support in musl? Is that still broken now? -- 此致 礼 罗勇刚 Yours sincerely, Yonggang Luo</div>
