Bootstrap failure on trunk on linux? (libgmp.so.3 exists, but not found)
I've been setting up a Debian box to do builds on, and make bootstrap on mainline is failing somewhere in the middle of Stage 1. The problem appears to be that it's not looking in the right places for libgmp.so.3 when it calls ./gcc/xgcc at the end of the stage. - The box, for what it's worth, is an out-of-the-box Debian Stable, with the latest GMP and fully-patched MPFR built by hand and installed in /usr/local/lib: ~/build-trunk ls /usr/local/lib firmware libgmp.a libgmp.la libgmp.so libgmp.so.3 libgmp.so.3.4.1 libmpfr.a libmpfr.la I used the following configure line: ~/build-trunk ../svn-source/configure --verbose --prefix=/home/brooks/gcc-trunk --enable-languages=c,c++,fortran --with-gmp=/usr/local --with-mpfr=/usr/local This appears to work quite well for a while; configure finds the mpfr and gmp libraries, and is quite happy with them. However, a good ways into the build, it fails on the following error (with a few messages quoted before that for context): gcc -c -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -fno-common -DHAVE_CONFIG_H -I. -I. -I../../svn-source/gcc -I../../svn-source/gcc/. -I../../svn-source/gcc/../include -I../../svn-source/gcc/../libcpp/include -I/usr/local/include -I/usr/local/include -I../../svn-source/gcc/../libdecnumber -I../libdecnumber../../svn-source/gcc/cppspec.c -o cppspec.o gcc -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -fno-common -DHAVE_CONFIG_H -o cpp gcc.o opts-common.o gcc-options.o cppspec.o \ intl.o prefix.o version.o driver-i386.o ../libcpp/libcpp.a ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a -L/usr/local/lib -L/usr/local/lib -lmpfr -lgmp /home/brooks/build-trunk/./gcc/xgcc -B/home/brooks/build-trunk/./gcc/ -B/home/brooks/gcc-trunk/i686-pc-linux-gnu/bin/ -B/home/brooks/gcc-trunk/i686-pc-linux-gnu/lib/ -isystem /home/brooks/gcc-trunk/i686-pc-linux-gnu/include -isystem /home/brooks/gcc-trunk/i686-pc-linux-gnu/sys-include -dumpspecs tmp-specs /home/brooks/build-trunk/./gcc/xgcc: error while loading shared libraries: libgmp.so.3: cannot open shared object file: No such file or directory make[3]: *** [specs] Error 127 make[3]: Leaving directory `/home/brooks/build-trunk/gcc' make[2]: *** [all-stage1-gcc] Error 2 make[2]: Leaving directory `/home/brooks/build-trunk' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/home/brooks/build-trunk' make: *** [bootstrap] Error 2 I'm not really sure what to make of this; libgmp.so.3 most certainly exists in the specified directory, configure had no problem finding the relevant files, and the line immediately before the one that fails has a -lgmp -lmpfr on it that works fine. However, there's a workaround: if I copy libgmp.so.3 into /lib, then the build works. (Or, at least, it gets to Stage 2; it's still going) It shouldn't be doing that, yes? - Brooks

If you tell a -compiler to use L/usr/local/lib, you're responsible for also setting up either an rpath or LD_LIBRARY_PATH to point at /usr/local/lib; doing it by default causes all kinds of problems. -- Daniel Jacobowitz CodeSourcery

Ah, okay. Thanks for the quick reply! I guess I was assuming that since GMP is supposedly only a prerequisite for building the compiler and not for using it, that it was being linked in statically rather than dynamically. But I guess that wouldn't apply to xgcc, since it's only used in the build (right?). - Brooks

I have been using this patch to make sure that GMPLIBS is linked statically so that I can install gcc binaries on machines without updated GMPLIBS.
