Description Tijl Coosemans freebsd_committer freebsd_triage 2014-02-17 15:50:01 UTC 
Compilation is currently broken with clang and "env CFLAGS=-Oz make".

libtool: link: cc -Oz -fno-strict-aliasing iconv_no_i18n.o -o .libs/iconv_no_i18
n  ../srclib/libicrt.a ../lib/.libs/libiconv.so -Wl,-rpath -Wl,/usr/local/lib
../lib/.libs/libiconv.so: undefined reference to `aliases2_lookup'
cc: error: linker command failed with exit code 1 (use -v to see invocation)
*** Error code 1

aliases2_lookup is an inline function that isn't inlined with -Oz so it
must be exported, meaning the code expects gnu89 semantics for the inline
keyword.

The patch below also enables -fvisibility=hidden and adds a patch to keep
some symbols like iconv_open visible.  It was disabled because it caused
these symbols to be hidden:
