[Bug other/16838] libiberty "link test vs. GCC_NO_EXECUTABLES" problem during sun cross
--- Comment #4 from davek at csh dot rit dot edu 2006-01-15 01:56 --- as a work-around, I was able to fix this problem by copying the config.cache from my root build directory into whatever directory was failing. On my GNU/debian system, I had to copy it to ./i686-pc-linux-gnu/libstdc++-v3/config.cache ./i686-pc-linux-gnu/libiberty/config.cache -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16838
[Bug bootstrap/25794] New: gcc won't link to new local glibc
I can't figure out how to get gcc to build using a local build of glibc. I've
built and installed glibc-2.3.6 in /usr/glibc2. As I understand it, I need to
make a cross-compiler in order to make gcc with the new glibc2 (nothing told me
to do this, its just the only way I can kinda get it to work) Here's my
gcc-build configuration:
../gcc-4.0.2/configure --enable-languages=c,c++ --with-sysroot=/usr/glibc2
--with-newlib
and my build command:
make BOOT_CFLAGS="-Wl,--dynamic-linker=/usr/glibc2/lib/ld-linux.so.2"
bootstrap4
which will make the stage1 compiler, but will fail as soon as it tries to use
it ->

It's still linking against /lib/ld-linux.so.2, which I don't think it should
be. I'm sure its a magic variable I'm not setting somewhere.
In short: how do you compile gcc with a local build of glibc?

--- Comment #5 from davek at csh dot rit dot edu 2006-01-16 20:48 --- still can't get it to work. I've tried at least 50 different configurations and had to wait an hour to see if each one would work. It always exits with undefined references to symbols in /usr/glibc2/lib/ld-2.3.6.so. I don't understand how this is not a bug. GCC WILL NOT COMPILE WITH MY GLIBC. Perhaps if someone told me how I should be doing that, I would know if the problem is with my GCC config or my glibc config. Glibc compiled, checked, and installed just fine. Not so with gcc. Sounds to me like a its a problem with gcc. I know since this is closed, probably no one will see this. But if anyone does, please please help me. I've been stuck on square one for weeks. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25794
