Priority: medium Bug ID: 76789 Assignee: dri-devel@lists.freedesktop.org Summary: [radeonsi] si_descriptors.c requires -std=gnu99 or -fms-extensions Severity: normal Classification: Unclassified OS: OpenBSD Reporter: jsg@openbsd.org Hardware: Other Status: NEW Version: git Component: Drivers/Gallium/radeonsi Product: Mesa
Mesa is compiled with -std=c99 but this does not allow anonymous structs within a union unless using a recent version of gcc.
When compiling with gcc 4.2.1 the following error is thrown when compiling the gallium radeonsi driver unless configure.ac is changed to have either -std=gnu99 or -std=c99 -fms-extensions.
