Lost C compiler - Help!

I sure hope someone can help out here! I upgraded our gcc from 2.91 to 2.95, using the rpm file. I thought it upgraded properly, but know for some reason, I no longer have a C compiler! I was going to install a module, and I get the error: Can not compile C compiler no working.

This is on a RH/Linux 6.2. Everything was working fine till I upgraded the gcc... which was probably a mistake!

I was hoping someone may guide in the right direction as how to get our C compiler back or what I need to do to re-install it.

TIA,

Mickalo

Biggest mistake. Just so you know, gcc, being the most critical utility in *NIX, should be upgraded only if you have a valid reason and know what you're doing.

>> what I need to do to re-install it

Backup your stuff and redo a fresh install. Ditch Redhat and go for FreeBSD if at all possible. Or simply reinstall with the latest version - 7.2.

You might try removing whatever RPMs you installed and installing/compiling gcc from the source, at

http://gcc.gnu.org

I think we all learn the "only upgrade if you have a really good reason" lesson a few times in the past. . .

I use RH 7.2 on a few different boxes now, and I have to admit that it's really tight. Hopefully you have separate /home, /usr, /tmp, and root partitions, this makes reinstalls much, much easier. . .

Thanks. this is what I was thinking of doing, installing from source. But if I don't have a C compiler, I can't install anything from source! that's how I found out in the first place, when installing MySQL 3.23.45 from source!

I would attempt to upgrade from our current 6.2 to 7.2,.. but I don't feel real sure about that. The dedicated server we're on has about 40 clients hosted on it, and I don't want to screw it up.

I'll contact our support to see if they can help me out.

YES!! I am learning the "IN's and OUT's" of a system admin,...THE HARD WAY!! :D

Sorry it didn't work, mickalo.

Have you tried just typing gcc -v ? To see if it's there at all?

Well after burning the midnite oil last nite. I was able to get it back,..I think!

I found the problem when attempting to install MySQL from source, and it wouldn't compile. If I now run this configuration:

CCFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors -fno-exceptions -fno-rtti" \
./configure --prefix=/usr/local/mysql --with-berkeley-db --without-docs --without-bench \
--without-readline --enable-assembler --with-mysqld-ldflags=-all-static \
--with-mysqld-user=mysql2 --with-low-memory --with-tcp-port=3307 \
--with-unix-socket=/tmp/mysql2.sock --localstatedir=/usr/local/mysql/var

I get the error message: CCFLAGS command not found
but if I remove this:

CCFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors -fno-exceptions -fno-rtti" \

and run it like this:

./configure --prefix=/usr/local/mysql --with-berkeley-db --without-docs --without-bench \
--without-readline --enable-assembler --with-mysqld-ldflags=-all-static \
--with-mysqld-user=mysql2 --with-low-memory --with-tcp-port=3307 \
--with-unix-socket=/tmp/mysql2.sock --localstatedir=/usr/local/mysql/var

it seems to compile without any errors. I didn't run the make or make install, I just wanted to see if it would get past the configuration, which it didn't yesterday, it does today.

If I enter: gcc -v it display the correct information now, as it did before I attempted to upgrade the gcc. I think I removed everything I tried to install. So I believe it's back to it's orginal state! I think.

If I attempt to use "export" at the command line, I get the error, "command not found.." not sure if this part of the problem or not. So right now I can't use the CCFLAGS= or CXX= enviromental variables.

What shell are you using?

/bin/bash as root

Is that incorrect?

It's all right. Just checking. Dunno why it doesn't like export ...

I tried it again, changed the shell in the /etc/passwd for root to /bin/bash, logged in,.. and bingo! I can export now.

Go figure! :D

I think I've got the problem resolved now... :)

I really appreciate all the help!
