Help with using multilib for Cilk Library

Hello Everyone,
	I am trying to use Multilib on Cilk Library. I looked at this website (http://www.airs.com/ian/configure/configure_8.html) and used libsanitizer and libgo as samples to model after. It is currently failing with the following error message:

libtool: link: /export/users/my-files/b-gcc-multilib/./gcc/xg++ -B/export/users/my-files/b-gcc-multilib/./gcc/ -nostdinc++ -nostdinc++ -I/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/32/libstdc++-v3/include/x86_64-unknown-linux-gnu -I/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/32/libstdc++-v3/include -I/export/users/my-files/gcc/libstdc++-v3/libsupc++ -I/export/users/my-files/gcc/libstdc++-v3/include/backward -I/export/users/my-files/gcc/libstdc++-v3/testsuite/util -L/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/32/libstdc++-v3/src -L/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/32/libstdc++-v3/src/.libs -B/export/users/my-files/install-gcc-multilib/x86_64-unknown-linux-gnu/bin/ -B/export/users/my-files/install-gcc-multilib/x86_64-unknown-linux-gnu/lib/ -isystem /export/users/my-files/install-gcc-multilib/x86_64-unknown-linux-gnu/include -isystem /export/users/my-files/install-gcc-multilib/x86_64-unknown-linux-gnu/sys-include  -m32 -shared -nostdlib /usr/lib/../lib/crti.o /export/users/my-files/b-gcc-multilib/./gcc/32/crtbeginS.o  .libs/bug.o .libs/cilk-abi.o .libs/cilk-abi-cilk-for.o .libs/cilk-abi-vla.o .libs/cilk-abi-vla-internal.o .libs/cilk_api.o .libs/cilk_fiber.o .libs/cilk_fiber-unix.o .libs/cilk_malloc.o .libs/c_reducers.o .libs/except-gcc.o .libs/frame_malloc.o .libs/full_frame.o .libs/global_state.o .libs/jmpbuf.o .libs/local_state.o .libs/metacall_impl.o .libs/os_mutex-unix.o .libs/os-unix.o .libs/pedigrees.o .libs/record-replay.o .libs/reducer_impl.o .libs/scheduler.o .libs/signal_node.o .libs/spin_mutex.o .libs/stats.o .libs/symbol_test.o .libs/sysdep-unix.o .libs/worker_mutex.o   -Wl,-rpath -Wl,/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs -Wl,-rpath -Wl,/export/users/my-files/install-gcc-multilib/lib/../lib64 -L/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs -L/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/libstdc++-v3/src -lpthread -ldl -L/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/32/libstdc++-v3/src -L/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/32/libstdc++-v3/src/.libs -L/export/users/my-files/b-gcc-multilib/./gcc/32 -L/lib/../lib -L/usr/lib/../lib -L/export/users/my-files/b-gcc-multilib/./gcc /export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so -lm -lc -lgcc_s /export/users/my-files/b-gcc-multilib/./gcc/32/crtendS.o /usr/lib/../lib/crtn.o  -m32 -m32   -Wl,-soname -Wl,libcilkrts.so.5 -o .libs/libcilkrts.so.5.0.3511

From what it looks like, it is reading the 64 bit library for the 32 bit mode (or vice-versa). How do I fix this? I am also attaching my configure.ac and Makefile.am. Please note that it is not fully cleaned up (e.g. I have stuff commented out etc). Can someone please tell me what I am doing wrong?

Any help is greatly appreciated!

Thanks,

Balaji V. Iyer.

When building the 32bit libcillkrts you are linking against the 64-bit
libstdc++.  It's right there on your command line:
/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.
 If that argument is needed at all, it needs to be
/export/users/my-files/b-gcc-multilib/x86_64-unknown-linux-gnu/32/libstdc++-v3/src/.libs/libstdc++.so
(note added /32 in there).  I guess the question is where the argument
is coming from.  I must admit that I don't know.  Is it in some
environment variable?

I am not setting any environment variable that weren't set automatically in my SUSE machine. Also, all the other libs are working correctly for 32 and 64 bit.

If you can create a git branch, others can take a look to
see what is going on.  There isn't sufficient info to tell.

OK.

> Also, all the other libs are working correctly for 32 and 64 bit.

That doesn't prove much one way or another, as the other libraries are
not written in C++.  Something is adding that explicit libstdc++.so
argument, but I don't know what.  I don't see it in your
configure/Makefile and I don't see it in the top-level
configure/Makefile either.  It could possibly be coming from libtool,
but I'm not sure how.

Hello H. J. and Ian,
	I have posted what I have in bviyer/cilkplus-multilib-test. To build the compiler, I used the following configure command:

../cilkplus-multilib-test/configure --prefix=<INSTALL_DIR>

Any help is greatly appreciated!

Thanks,

Balaji V. Iyer.

Here is a patch:

1. Add target dependency on C++ for parallel build.
2. Remove hardcoded -O3 -fpic. libtool takes care of it.
3. Work around MAKEFLAGS for multilib build.

Hi H.J.,
	Thank you! This patch got rid of all the errors for me. When I do make install, it is installing both the 32 bit one and 64 bit one in $INSTALL_DIR/lib. How can I make the 32 bit one write to $INSTALL_DIR/lib and the 64-bit one write to $INSTALL_DIR/lib64?

Thanks,

Balaji V. Iyer.

Try this:

 # Target list.
-lib_LTLIBRARIES = libcilkrts.la
+toolexeclib_LTLIBRARIES = libcilkrts.la

on libcilkrts/Makefile.am.
