Bug 268647 – dev-libs/glib-2.18.4-r1: fix uclibc cross-compilation

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Bertrand Jacquin 2009-05-04 18:40:05 UTC]

glib doesn't build glib/test/strfuncs.c while cross-compilated with uclibc :

make[4]: *** [strfuncs] Error 1

isnan is actually defined in math.h, but by default _POSIX_SOURCE doesn't define "isnan define". Adding -D_C99_SOURCE to strfuncs.c compile line correct issue.

Here is patch for glib/tests/Makefile.am and glib/tests/Makefile.in. Only glib/tests/Makefile.in should be applied here as Makefile.in is not regenreted.



Reproducible: Always

Steps to Reproduce:
1. crossdev -t i586-geode-linux-uclibc
2. emerge-wrapper --init
3. i586-geode-linux-uclibc -vat glib
