However, the C++ source (which requires renaming the file suffixes from .cpp, to .cc, to be recognised by the toolchain) had some issues, when I last tried to build it.
To help firm up the compatibility of JUEL, for multimedia applications, it may be interesting to port Apple's ALAC, and ValidateMP4 projects to Orion.
This enhancement is just to track the expansion of our UNIX/POSIX API surface, and doesn't necessarily block the progress of #7.
So far, these projects don't fully-build, since we still lack some functionality in liblinux, but we now have
atoi(), and some new headers (e.g.cstring, andxlocale/*), which should improve compatibility, in other areas:
