Description Michał Górny archtester

2012-01-15 16:25:39 UTC

If dev-libs/libbsd is installed while perl is being built, perl detects it and enables relevant header file parts.

When portage unmerges libbsd later, random packages using perl headers fail to build:

/usr/lib64/perl5/5.12.4/x86_64-linux/CORE/perl.h:5905:63: fatal error: libutil.h: No such file or directory

Doesn't this remove some point in having libbsd?

no, those headers are deprecated and the replacements live in /usr/include/bsd/
and should be used like this:

to use #include <bsd/libutil.h> in the code:

pkg-config --cflags libbsd

to use #include <libutil.h> in the code:

pkg-config --cflags libbsd-overlay

ssuominen@null ~/gentoo-x86/dev-libs/libbsd $ pkg-config --cflags libbsd-overlay
-isystem /usr/include/bsd -DLIBBSD_OVERLAY  
ssuominen@null ~/gentoo-x86/dev-libs/libbsd $ pkg-config --cflags libbsd
 
ssuominen@null ~/gentoo-x86/dev-libs/libbsd $
