gcc version in red hat Linux

should the version getting from gcc -v match one from rpm -qa|grep gcc?

Re: gcc version in red hat Linux

It depends.

It's possible to download a GCC source kit,
and build and install a GCC that way, and
that wouldn't appear in any "rpm" report.

Is there some actual problem which you are
trying to solve?

Call me curious, but what do they say?

gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-59)
$rpm -qa|grep gcc
gcc-3.4.6-3

so which version of gcc is: 3.4.6-3 or 3.2.3?
Any idea to share?

Could be both, but I'd bet that you have (at
least) "gcc version 3.2.3 20030502 (Red Hat
Linux 3.2.3-59)" installed. GCC is seldom
confused about its own version.

which gcc
echo $PATH

Multiple versions of GCC can be installed in
different places. A bare "gcc" will get you
the first "gcc" found on your PATH. I don't
run Red Hat, so I know nothing, and among the
things I don't know is where "rpm" would have
installed the "gcc" from your gcc-3.4.6-3
kit.

find /usr -type f -name gcc

(Or anyplace else you think likely.)

Re: gcc version in red hat Linux

there is only gcc executable on the system. it seems info in the package database is different from that directly on the executable.

Yes, ofcourse.

# gcc --version
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-46)

# rpm -qa | grep gcc
gcc-4.1.2-46.el5_4.2

OS is RHEL 5.4

Re: gcc version in red hat Linux

It has to be reinstalled to clear the inconsistnecy. Thanks all for your thoughts.
