Re: compiling gcc 2.95.3 under ubuntu 10.04.2, x86_64

Hi Andrew,

Here's the relevant bit from the website I referenced:
***
GCC 2.95.x
About half of the changes needed for GCC 3.0.x are also applicable here (e.g. Makefile fixes, lib32 fix-ups, spec flags, etc). Unfortunately, the other half are workarounds for compiler and glibc nuances that are fixed in later releases. One of the big changes needed is a workaround for the internal use of an _IO_MTSAFE_IO define. This define causes an error due to a missing header due to difference in glibc headers included with modern Linux distributions (see here and here for more info). Luckily, a straightforward workaround is to use glibc's generic stdio-lock.h header, which in my case needed to be pulled from the glibc 2.10.1 source to match my installed version. Additionally, another glibc fix is required due to an unnamed union declaration (see this bug) inside a pthread header which is not supported by GCC 2.95.x. To workaround the issue I pulled in the glibc 2.10.1 system dependent pthreadtypes.h header from the source and appended a variable name (e.g. __gcc_295_workaround__) to the unnamed union declaration. Build this version using the provided patch @ (gcc-v2.95.x.debian.x86_64.diff)
and the following instructions:

# shell commands
tar xzf glibc-2.10.1.tar.gz
mkdir -p gcc-2.95.3/glibc-workaround/include/bits
cp glibc-2.10.1/bits/stdio-lock.h gcc-2.95.3/glibc-workaround/include/bits
cp glibc-2.10.1/nptl/sysdeps/unix/sysv/linux/x86_64/bits/pthreadtypes.h gcc-2.95.3/glibc-workaround/include/bits
sed -i -n '1h;1!H;${;g;s/\(__pthread_slist_t __list;\n[ \t]*}\)/\1 __gcc_295_workaround__/g;p;}' gcc-2.95.3/glibc-workaround/include/bits/pthreadtypes.h
tar xzf gcc-2.95.3.tar.gz
cd gcc-2.95.3
patch -p0 < gcc-v2.95.x.debian.x86_64.diff
mkdir ../gcc-2.95.3-objdir
cd ../gcc-2.95.3-objdir
../gcc-2.95.3/configure --prefix=/opt/i386/gcc/gcc-2.95.3 --enable-languages=c,c++ --enable-threads=posix --enable-shared --host i386-pc-linux-gnu
make
make install

I also attached my logs: gcc295.log / gcc295.err in plain text.

If you have any success compiling GCC 2.95 on your own without using the method above please let me know too!

Thank you,
Roman.
