It looks like you are trying to build gcc 3.1.1 and 3.2.3 with the current gcc. This is known to fail. It is (unfortunately) the case that if you want to build an old version of gcc, you sometimes have to walk backward--use version N to build version N-1, use version N-1 to build version N-2, etc. You don't have to hit every version, but you can't skip too far. > 3.3.6 old compiler builds. branch bootstrap fails with: Actually, there is no longer any reason to use the gcc-in-cxx branch. What you should do now is build trunk using the configure argument --build-with-cxx. > make[3]: Entering directory > `/home/jlquinn/gcc/dev/gcc-in-cxx/host-x86_64-unknown-linux-gnu/gcc' > g++ -c -g -g -DIN_GCC -W -Wall -Wwrite-strings -Wcast-qual > -Wmissing-format-attribute -fno-common -DHAVE_CONFIG_H -I. -I. > -I../.././gcc -I../.././gcc/. -I../.././gcc/../include > -I../.././gcc/../libcpp/include -I../.././gcc/../libdecnumber > -I../.././gcc/../libdecnumber/bid > -I../libdecnumber ../.././gcc/c-lang.c -o c-lang.o > In file included from /home/jlquinn/gcc/dev/run/gcc336/include/c > ++/3.3.6/iosfwd:46, > from /usr/include/gmp-x86_64.h:24, > from /usr/include/gmp.h:59, > from ../../gcc/double-int.h:24, > from ../../gcc/tree.h:30, > from ../../gcc/c-lang.c:27: > /home/jlquinn/gcc/dev/run/gcc336/include/c > ++/3.3.6/x86_64-unknown-linux-gnu/bits/c++locale.h:61:40: attempt to use > poisoned "malloc" We may need to ensure that when using C++ gmp.h is included before system.h.
