Summary: Code uses _GNU_SOURCE to determine locale facilities
are available
Product: Mesa
Version: 7.9
Platform: Other
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Other
AssignedTo: [email protected]
ReportedBy: [email protected]
In two places, the code use #if defined(_GNU_SOURCE) to determine whether
certain locale facilities are present in the environment.
I suspect the code wants to test whether the C library is the GNU C library,
which is __GLIBC__. _GNU_SOURCE is something the source file sets to tell the
GNU C Library header files that the code is designed for GNU extensions in that
library.
Incidentally, just having GNU C Library isn't enough to know these facilities
are available. It takes a recent version of it. For example, I found GNU C
Library Version 2.2.2 does not have them.
The two places are:
src/glsl/strtod.c
src/mesa/main/imports.c
