Hi,
In CURRENT, clang can not compile database/db42.
here is a error message:
BEGIN>---8<ERROR MESSAGE>8---
/usr/bin/ld: .libs/cxx_db.o: relocation R_X86_64_32S against `_ZTV2Db'
can not be used when making a shared object; recompile with -fPIC
.libs/cxx_db.o: could not read symbols: Bad value
c++: error: linker command failed with exit code 1 (use -v to see
invocation)
*** [libdb_cxx-4.2.la] Error code 1
Stop in /usr/ports/databases/db42/work/db-4.2.52/build_unix.
*** [do-build] Error code 1
Stop in /usr/ports/databases/db42.
END>---8<ERROR MESSAGE>8---
linker said 'recompile with -fPIC'.
Actualy,
BEGIN>---8<COMPILE LOG>8---
c++ -c -I. -I./../dist/.. -D_THREAD_SAFE -O2 -fno-strict-aliasing
-pipe -fconserve-space ./../dist/../cxx/cxx_txn.cpp -DPIC
END>---8<COMPILE LOG>8---
there is a -DPIC flag, but not -fPIC.
Why not?
db42 uses its own libtool rather than FreeBSD's ${LOCALBASE}/bin
/libtool.
configure said:
BEGIN>---8<PART OF configure>8---
LIBTOOL= '$(SHELL) ./libtool'
END>---8<PART OF configure>8---
this libtool compiles c++ source without -fPIC flag if CC is clang.
libtool in ${LOCALBASE} was patched for FreeBSD. but db42
libtool was NOT. so -fPIC flag was lost.
Here is a patch for fix this issue.
I'd send-pr this issue as ports/173627.
But
http://www.freebsd.org/cgi/query-pr.cgi?pr=173627
said "No PRs Matched Query"
So I posted it here.
Would you like to review/commit this patch?
Thanks.
