following is the problem that I faced during the installation process of gcc-3.0.4
the steps I followed >>

* gunzip and tar -xf al gcc-3.0.4*.tar.gz files
* mkdir gcc-build;cd gcc-build
*then the following problem occured......

ot@localhost gcc-build]# /usr/gcc/gcc-3.0.4/configure --prefix=/opt-program-suffix=-3.0.4
Configuring for a i686-pc-linux-gnu host.
Created "Makefile" in /usr/gcc/gcc-build using "mt-frag"
/tmp/cNf3807/cNf3807.pos: line 7: cc: command not found
*** The command 'cc -o conftest -g conftest.c' failed.
*** You must set the environment variable CC to a working compiler.


prior to this we got these results

to my knowledge there is a previous version of gcc is installed in /usr/libexec/i386-......
so I set the environmental variable for the new gcc and don't know whether it has been correctly set .The above command would display all my efforts in setting up environmental variable and the following I tried after above stuff

[root@localhost gcc-build]# make
Configuring in ./libiberty
creating cache ./config.cache
checking host system type... i686-pc-linux-gnu
checking build system type... i686-pc-linux-gnu
checking for ar... ar
checking for ranlib... ranlib
checking for gcc... no
checking for cc... no
configure: error: no acceptable cc found in $PATH
make: *** [configure-target-libiberty] Error 1


[root@localhost gcc-build]# make install
/bin/sh /usr/gcc/gcc-3.0.4/mkinstalldirs /opt-program-suffix=-3.0.4 /opt-program-suffix=-3.0.4
mkdir /opt-program-suffix=-3.0.4


please anybody who got answers for the above situation reply immediately because we are stuck in the middle of a PROJECT AND IM AN APPRENTICER ...TO THIS FIELD

It looks like you're trying to compile a compiler, without a compiler; clasic

It also looks like you might be running RedHat; so why don't you just install the RPM?
