Legacy compatibility headers for the musl C library.
If you wish to install everything, you can use the following:
gmake && gmake installIf you wish to install just the system headers, you can use:
gmake install-sysheadersAnd, if you wish to just install the error.h header along with the library
containing its functions, you can go with:
gmake && gmake test-libegacy-compat \
&& gmake install-libegacy-compatThat's pretty much about it.
In your LDFLAGS, add the value of -legacy-compat.
Yeah, simple as that.
error.h and error.c, part of libegacy-compat, are covered by the
BSD 2-Clause licence, along with the Makefile itself.
Maybe this library can be updated and more compatibility functions be added
along the time, but there's no guarantee of that for now.
sys/tree.h was copied verbatim from the NetBSD
source-tree by the Void Linux project, so it's covered
by the BSD 2-Clause licence too;
sys/queue.h was also copied from NetBSD, but it's covered by the BSD 3-Clause
licence, with its ownership claimed by The Regents of the University of California;
sys/cdefs.h came from Alpine Linux at some point
in history, but it hasn't a copyright header --- and, to be honest, it isn't
in fact copyrightable, since it does only provide some aliases to macros
utilized improperly
by some folks in programs, since it should be only used internally at the
GNU C Library.
The test of error_at_line(3) was taken from GNU m4 1.4.18 configure
Shell script, so it's covered --- or better, not covered --- by the
FSF Unlimited License.
