Dear Friends i just completed installing GCC-4.4.2 ,since i wasnt able to upgrade my kernel-2.6.18(RHEL 5) to the latest 2.6.31....so i followed blindly the instructions for installing GCC on the site linuxfromscratch.com .....though i think i got some errors i was able to install GCC-.. and i think only C was installed as i am able to compile the C++ programs not the .c ones...and heres the output for the command #gcc -v and #g++ -v

so please can someone help me with this issue,and how can i change the THREAD MODEL to POSIX,i changed the directory to compile the kernel source files..and typed in the command #make xconfig.....and this gave me many errors,which i didnt get before upgrading from GCC-4.1.1 to GCC-4.4.2....also i am not able to compile a normal C file.....please help
thanking you all in anticipation

There is, may be, a slight possibility to build gcc-4.4.2 on Fedora 12
( release next week ) from the development package gcc-4.4.2-7.fc12.src.rpm,
which is meant to be used in Fedora 13 , June 2010. Binutils 2.19.51 is required,
I think. The necessary 21 patches are included :
http://download.fedora.redhat.com/pu...7.fc12.src.rpm
.. Please read the file ' gcc.spec ' ..

hello knudfl,i did succeed in installing the GCC-4.2.2,by making the default compiler gcc34(using command #export CC=gcc34 )...but i have a query regarding the output of the following command

# gcc -v

Target: i686-pc-linux-gnu
Configured with: ./configure
Thread model: posix
gcc version 4.4.2 (GCC)

i installed just without any parameters passed to ./configure..then make and then make install,moreover i installed GCC-CORE-4.4.2 and then used the command export CC=GCC34 again to reinstall the GCC-4.4.2 using this command

../gcc-4.4.2/configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-languages=c,c++,objc,obj-c++,java,fortran

now is it ok ..as to what i have done??i was able to make most of the commands for installation of the new kernel-2.6.31.6,but i am not able to get into the kernel successfully,"kernel panic" !!! ,i hope this isnt bcoz the way i have installed the new GCC-4.4.2

and also please help me in installing the patches given by u thru in the link http://download.fedora.redhat.com/pu...7.fc12.src.rpm ..
...please help me regarding this

Kernel-2.6.31.6 is not supposed to compile with gcc-4.4.2 . ?

Gcc-4.4.2 will probably be ready for use in april > Ubuntu 10.04.

? ? Did you run the tests, LFS § 6.15.1 : make -k check
Running make with gcc one time isn't enough.
Hence the three sections gcc in LFS.
It is compiled with itself multible times, and doing all
is important.
Pass 2 uses gcc4.x from pass 1, pass 3' uses the pass 2 gcc4.x .
.....
Example using ' patch ' :
Copy all patches into gcc-4.4.2/
cd gcc-4.4.2/
' patch -p1 < "name-of-patch-file" '
like ' patch -p1 < 10-fix-this.diff '
.....

And I hope, that your old kernel is still present,
so you can boot into that.
