Hi ...

Currently I have gcc version 3.4.5. I need gcc 3.4.2 ... so I tried installing it. while doing configure i got error saying

" command not found
*** The command 'x86_64-host_redhat-linux-gcc -o conftest -g -O2 conftest.c' failed.
*** You must set the environment variable CC to a working compiler."
Can any one help me out ....

Thanks in advance

Regards
Prakash

Hi -

Q: You need to get GCC 3.4.2, so you downloaded the source, and you're trying to use your existing GCC 3.4.5 compiler to build it, correct?

Q: The first step to building 3.4.2 is to run "./configure", and that's where you got the error "" command not found", correct?

Suggestions:
1. It would be easier if you could simply find a 3.4.2 binary for your system. For example, an .rpm. Please try that, OK?

2. Otherwise, please confirm that you actually HAVE a viable compiler. Type this, and cut/paste the output:

Quote:

gcc --version

whereis gcc

3. Finally, look at the comments at the top of your "configure" script (or at the README that accompanies it) and see if it takes any command line arguments that might help.

4. Please post back what you find. Please cut/paste exact commands and exact messages.

Hi Prakash

You should get output of "whereis gcc" somthing like this,

Code:

[root@km-vmqa-dhcp187 ~]# whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz
[root@km-vmqa-dhcp187 ~]#

Can you run this command,

Code:

[root@km-vmqa-dhcp187 ~]# echo $PATH
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
[root@km-vmqa-dhcp187 ~]#

are you getting path as above ?

Btw what OS you have ? If you are not getting output as above then you have to set PATH variable.

#export PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

Only if you are Using CentOS, Fedora Or RedHat.

This confirms you have gcc installed (specifically, gcc 3.4.5). Good

Not good

. That's precisely why "config" is failing - because it can't find gcc.

Please try ashish_neekhra's suggestions:

Quote:

1. Type "echo $PATH". Cut paste the results.

2. Here is one way to find "gcc" (so you can add it to your $PATH):
find / -name gcc -print 2> /dev/null

3. Tell us what distro and version you're using.
One command might be "cat /etc/*release*".
Another is "uname -a"

4. Is your version 64-bit or 32-bit?
Do you need to compile for 32-bit, 64-bit ... or does it not matter?

Hi thanks ashish_neekhra & paulsm...

@ ashish_neekhra, echo $PATH giving result as
snb022:core# echo $PATH
/usr/local/bin/svos:/usr/local/bin64:/usr/local/bin64/numa:/usr/local/bin:/usr/local/bin/numa:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11R6/bin:/usr/local/boxboroex/bin:/usr/local/tylersburg/bin:/usr/local/rcf/tbg/bin:/usr/local/python/boxboroex/bin:/usr/local/python/bin:/usr/local/bin:/usr/local/bin/alchemy:.:/root/bin:/usr/local/boxboroex/bin:/usr/local/tylersburg/bin:/usr/local/python/boxboroex:/usr/local/python/tylersburg:/usr/local/python/bin:/usr/local/bin/alchemy

and I tried exporting the gcc path it is giving error : "-bash: date: command not found"

and I have redhat OS.

@ paulsm.. It is 64 bit OS. and

I am using Red Hat Linux release 7.0 (Guinness)

Thanks
