gcc 4.7 or Red Hat Developer Toolset equivalent for Centos?

[_ck_]

Oh I missed the release!
So first did a yum uninstall for the devtoolset 1.0 gcc

[code]
yum --enablerepo=testing-devtools-6 remove devtoolset-1.0-gcc
[/code]

Then I had to edit the .repo file to add -1.1 to the devtoolset path

Then I was able to successfully install gcc from devtoolset-1.1 - it found an old dependency to remove and installed the new runtime

yum --enablerepo=testing-devtools-6 install devtoolset-1.1-gcc

I tested devtools-1.1 on CentOS 5 x86_64.
These packages saved me a lot of work, thank you!
Everything installs and works as expected.

One minor thing (I guess it's the same in RHEL): unlike gcc-gfortran 4.1, devtoolset-1.1-gcc-gfortran has no f95 link and LAPACK build system picks old gfortran through f95 as default compiler.

Worked fine on my Centos 5 - x64

thx a lot guys !

[fuzzylogic]

Linux n00b here. So I was able to install the devtoolset-1.1 and enabled the toolset, and I can run gcc --version to see that gcc is working.
However, if I close the terminal and open a new one and run gcc --version it says it cannot find gcc.
Any suggestions?

[TrevorH]

You run the scl command and it starts a copy of bash with the environment set up to find the correct copy of gcc. If you close the window and want another one then you have to rerun the scl command.

[fuzzylogic]

Thanks for the reply. I should have been more specific, what command can I run so that gcc is always available and that I don't have to run scl each time? Some other programs that I'm trying to run are giving me errors that they can't find gcc utility.

[DaemonProgrammr]

I think you can add this command to the .bashrc file in your homedirectory.
This is a script file that gets executed everytime you open a terminal. (IIRC!)

This way, you always have the gcc command.

Hi,

initial rebuild at http://people.centos.org/tru/devtools-1.1 for CentOS 5/6 x86_64.

Please test and report so that we can push it to the main repositories.

Hi.

Is this still the appropriate repository for installing the Developer Toolset?
I'm unaware of which repository it is pushed to.

Thank you!

[TrevorH]

That URL contains a .repo file and, yes, as far as I know, that's still current.
