How to install gcc 2.7.2 in Solaris ?

I tried to install gcc 2.7.2.2 (x86). But it not works ("installation problem, cannot exec 'cpp' : No such file or directory"). Why? I copied gcc...tar.gz into /usr/local and ungzipped/untared. Also I copied all files into /usr/pkg/gcc-2.7.2/. May be I made something wrong?

The problem is if you dont have buyed the SParc Works Compiler from Sun that you dont have a compielr to build gcc with. B ut dont fear. On ftp://ftp.darkface.pp.se/pub/sun do you find the package FSFgcc.gz and a gunzip to decompress it with. Then run pkgadd -d./FSFgcc and install that precompiled compiler. Its installed in /opt/gnu. NOW you got a compiler. Download the latest gcc and untar it. Then in the gcc directory run a ./configure (make sure /opt/gnu/bin is first in your path). After that run make. After that run 'make stage1' and after that run 'make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2"', then run make stage2 and then run 'make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O2"' and then run as root 'make install CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O"'. Take /opt/gnu/bin out of your path and try the new compiler out. If it works run pkgrm and deinstall the FSFgcc package. You should then have a brand new working gcc

Probably, you have an already precompiled compiler. Check the
subdirectory "lib/gcc-lib" in your main GCC directory, then
goto it and search for another subdirectory, name of which
resembles your operating system (it's "sparc-sun-solaris2.5" on
my machine), then goto it and search for a subdirectory,
name of which is equal to GCC version (it's "2.7.2.2" on
my machine). This last subdirectory usually contains all the
parts of GCC, and you should use option -B to say the compiler,
where to search its parts. For example, insert the following
lines in your makefile:

  CC = ${GCCHOME}/gcc
  CFLAGS += -I${GCCHOME}/include -B${GCCHOME}/

and do the following command in your C-shell:

  setenv GCCHOME ${YOURGCCDIR}/lib/gcc-lib/<YourOS>/2.7.2.2

Of course, you can use a different name instead of GCCHOME.
Pay attention to "-I" option and last slash in "-B" option -
they are important. And this method doesn't require to have
GCC on your search path.
