Summary: dev-libs/libbsd: bsd/stdio.h does not declare asprintf() function prototype

Description Richard Yao (RETIRED) gentoo-dev 2012-04-29 14:20:17 UTC
`man 3 asprintf` claims that asprintf() is available under both GNU and *BSD systems, but it is not available when using bsd/stdio.h. This provides the following QA notice when compiling a port of btxld:

 * QA Notice: Package triggers severe warnings which indicate that it
 *            may exhibit random runtime failures.
 * btxld.c:557:2: warning: implicit declaration of function 'asprintf' [-Wimplicit-function-declaration]

It looks like we can turn this on by setting __USE_GNU, but that would have consequences beyond providing asprintf(). It might be easier to patch the bsd/stdio.h header to provide a asprintf() function prototype, but the correct solution probably requires more thinking.

I receive so much bug mail that I missed your responses. Anyway, I have filed the upstream bug as you requested.
