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 reply to this.Thank you.

Dude, it doesn't sound like you've got gcc installed.

1. If you really think "gcc" is somewhere on your system, you can search for it with a brute-force method like this:2. The "/usr/gcc/gcc-3.0.4" you downloaded is apparently a *source* distribution. In other words, you need to build it. And of course, you can't build it (or anything else) without an existing compiler.

3. The *easiest* approach is to just download a binary gcc RPM. For example:

http://www.rpmfind.net/linux/rpm2htm....php?query=gcc

http://rpm.pbone.net/

'Hope that helps .. PSM

and WHY do you need such an OLD gcc( gcc-3.0.4) this in not even the legacy gcc3.4

even IF you manage to get that antique compiler installed i dought that ANYTHING you might be able to build will even run .

Gcc 4.4.1 is the current

while installing gcc 4.4.1 rpm i got following error
so i searched to download glibc-devel-2.3.4-2.19.i386.rpm
but it was not available..


[root@localhost tmp]# rpm -i gcc-4.3.0-8.i386.rpm

Can you help me with this...

You don't say which distribution you are running, but either:

-- or --

Should work.

The Distribution is Red Hat Enterprise Linux AS4
and the above commands didn't work.!

use the rhel 4 command "up2date "

yum is used in rhel 5

for rhel 4 i think that gcc3.4 was the default
depending on when the last update from red hat was ( when did you stop paying red hat for updates) that might have been updated -- maybe-
