Dear all, I am using the latest RTEMS 6 tools and sources. When building a C++
application including libbsd I receive two errors from GCC.
thanks for your patches. Could you please change your Git configuration
so that your full name is present as the patch author.
The first one complains about the macro BITSET_DEFINE within freebsd/sys/sys/_domainset.h. I think this relates to a patch "sys/bitset.h: reduce
visibility of BIT_* macros" within the freebsd sourcehttps://github.com/freebsd/freebsd-src/commit/5e04571cf3cf4024be926976a6abf19626df30be.
I ve simply changed BITSET_DEFINE to __BITSET_DEFINE as shown in the patch.
This makes compilation work on my side, but there are a few other occurences of
BITSET_DEFINE within rtems and libbsd.
This change is fine. It is already fixed like this in the FreeBSD
upstream. Please send the patch again with a proper author name.
The second one is triggered by the function getrusage in
rtemsbsd/include/bsd/sys/ressource.h.
There is a another declaration in include/sys/ressource.h provided with the
toolchain.
Now, one has C Linkage the other one C++ Linkage which leads to a conflict. I
ve simply made the one in libbsd invisible to the C++ compiler.
This is a bug in Newlib (newlib/libc/include/sys/resource.h). This file
needs the C++ extern "C" stuff.
