FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a versatile software implementation that runs on any commodity hardware. From a Raspberry PI to a multi-core server, FreeSWITCH can unl
GNU variant of strerror_r() returns char *, while the XSI version returns int.
To make things worse, glibc ships both and added a unused result warning
in recent versions (2.16) causing the build to fail.
Add our own custom wrapper that always returns a pointer to the message buffer
and additionally make XSI versions of strerror_r() GNU compatible by
returning "Unknown error xxx" if no error message is available.
Fixes:
src/switch_rtp.c: In function 'rtp_common_read':
src/switch_rtp.c:3313:15: error: ignoring return value of 'strerror_r',
declared with attribute warn_unused_result [-Werror=unused-result]
cc1: all warnings being treated as errors
