Annnnnd that's untrue. The issue stems from a rpath issue. As part of fedora
packaging guidlines we aren't allowed to have embedded rpaths that are
system rpaths (like /usr/lib64) etc. So the spec file runs this.
sed -i 's|^hardcode_libdir_flag_spec=.*|hardcode_libdir_flag_spec=""|g'
libtool
sed -i 's|^runpath_var=LD_RUN_PATH|runpath_var=DIE_RPATH_DIE|g' libtool
to remove that... which results in within tools directory:
DIE_RPATH_DIE="/usr/lib64:$DIE_RPATH_DIE" g++ -Wall -g -O2 -g -pipe
-Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m64 -mtune=generic -o .libs/bjdwp bjdwp.o
../src/.libs/libbarry.so ../src/.libs/libbarryjdwp.so -lpthread
/usr/bin/ld: warning: libbarrydp.so.17, needed by
../src/.libs/libbarryjdwp.so, not found (try using -rpath or
-rpath-link)
../src/.libs/libbarryjdwp.so: undefined reference to
`Barry::JDG::LoadDebugInfo(Barry::JDG::DebugFileList const&, unsigned
int, std::basic_string<char, std::char_traits<char>,
std::allocator<char> >, Barry::JDG::CodInfo&)'

collect2: ld returned 1 exit status
if I manually run
DIE_RPATH_DIE="/usr/lib64:$DIE_RPATH_DIE" g++ -Wall -g -O2 -g -pipe
-Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m64 -mtune=generic -o .libs/bjdwp bjdwp.o
../src/.libs/libbarry.so ../src/.libs/libbarrydp.so.17
../src/.libs/libbarryjdwp.so -lpthread
it completes...
I'm not sure what Makefile.am or whatever to modify to have it add
that dependency when building/linking.
