Hi,
I am trying to add support for the musl toolchain to FFmpeg.
FFmpeg needs
support for library features defined in POSIX.1-2001 with XSI
extension and the standards below. Currently configure
probes the host and target libc by checking for defined macros
like __GLIBC__ and __UCLIBC__. In case of glibc and uclibc it sets
-D_XOPEN_SOURCE=600 properly.
After this it checks for some combinations of hardware and the
probed libc to set some more compile options, if necessary.
I know that musl does not have a macro __MUSL__ and I have read
the explanation. However, I don't understand what's meant by "[..]
it's a bug to assume a certain implementation has particular
properties rather than testing." and how does it affect the way FFmpeg
probes for the libc.
What could be a solution which supports musl?
Many thanks!
Jörg
