Are you supposed to be able to use gcc to build userland binaries if you built world with clang?
I'm on -CURRENT as of a few days ago (using armv6 but i'm not sure if that
matters). If I buildworld with clang, then attempt to compile some userland
binaries with gcc, I'll get missing symbols like:
CCLD pcretest
./.libs/libpcre.so: undefined reference to `__clear_cache'
*** [pcretest] Error code 1
If I look at /lib/libgcc that symbol isn't there:
# readelf -a /lib/libgcc_s.so.1 | grep clear
#
If I rebuild /usr/src/gnu/libgcc with gcc, then try again it works. The symbol
is now there:
# readelf -a /lib/libgcc_s.so.1 | grep clear
94: 00003b94 48 FUNC GLOBAL DEFAULT 12 __clear_cache@@GCC_3.0
#
I can build pcre correctly. I thought one of the goals was to be able to use
both interchangeably on the same system. Is this broken, or one of the
casualties of making clang default now? Do we need two different versions of
some libraries depending on which compiler is being used?
