Hi,
i already have gcc 3.4.3 on my machine and i want to install gcc 2.95.2
i am using the following commands

./configure --prefix=/usr/local
make bootstrap
make install

(gnu make version is 3.80)
i am getting following error in "make bootstrap" sequence

echo "void __foo () {}" > dummy.c
/export/home/ads/gcc-2.95.2/gcc/xgcc -B/export/home/ads/gcc-2.95.2/gcc/ -B/usr/local/i386-pc-solaris2.11/bin/ -I/usr/local/i386-pc-solaris2.11/include -DIN_GCC -o -I./include -c dummy.c

make[1]: *** [libgcc1.null] Error 1
make[1]: Leaving directory `/export/home/ads/gcc-2.95.2/gcc'

How i can fix this?



Thanks in advance

So... is this OpenSolaris? What build? Or is it Solaris 11 Express?

It is open solaris based Operating system ( schillix). and i am trying to install the gcc 2.95 compiler.
for that thee are threee steps
./configure
make bootstrap ---> here i am getting the error which i describe in my previous post.
make install

Ok, from searching on your error message, "version `SUNW_1.23' not found", I found that if this were OpenSolaris you'd need to be on at least build 38. So try updating your system to the latest so you get the right C libraries.

Well, gcc-2.95 is interesting, as it doesn't compile on any newer Linux OS.
The preferred version should be gcc-2.95.3.
OpenSolaris 2009.06 was used. With gcc-3.4.3-csl-20050525.i386.tar.bz2
unpacked in ///home/knudfl, and a link made from gcc-3.4.3/bin/gcc to
/usr/bin/gcc343.
( ftp://ftp.uni-ulm.de/mirrors/schilli...5.i386.tar.bz2 )

export CC=gcc343 && mkdir build-gcc295 && cd build-gcc295/ &&
../gcc-2.95.3/configure --prefix=/usr/local/gcc295 --enable-shared --verbose
&& make bootstrap : No errors.

Three things : 1) gcc requires a build directory outside the source.
2) GCC-2.95.2 is not bug free.
3) And it is a good idea to install any extra gcc to a hideaway location,
to insure, that none of the files make any conflicts with the default gcc.
