hi all,
i couldnt compile 2.6.7 and older kernel on Mandriva 2006. is the reason that Mandriva has gcc 4.0.1.
what can i do? is there any solution for kernel compilation with gcc 4.0.1?
thanks.

May I ask why you're looking to use that old of a kernel version?

Mandriva 2006 ships with 2.6.12. Also, keep in mind, that any kernel for Mandriva needs to have a few, special modules loaded into it. I don't know where you can get these modules, other than from the Mandriva 2.6.12-12mdk kernel source (which is included on the install DVD/CDs).

i m trying to install rtlinux. in order to install rtlinux, first of all, i have to install kernel 2.4 or 2.6.9prepatched ones. in order to compile them, i need gcc 2.95.3 otherwise $make menuconfig command does not work.

hmmm....

I'm not saying this is the best idea, or the fastest, but I would maybe suggest installing a secondary linux distro onto another partition - an older version of a linux distro, or even Debian! I'm pretty sure Debian uses the 2.4 kernel. So, just install an older version of a distro, and then use that distro's older version of gcc.

OH, I just had another idea (I'm sorry, I just woke up ), go to the GCC download page and download an older version, and change the $PREFIX= value when installing it.

I hope this helps in some way. I'm not even fully awake yet.

sorry about that but i m a newbie on linux. what is $PREFIX= value and how can i change it. also is there any easy way to install gcc 2.95.3 .
thanks

oh that's fine.
I'd never heard of rtlinux until I read this post (then I googled it).

If you download a source tarball from http://gcc.gnu.org/releases.html you will need your currently existing gcc. I'm not sure how much you know about compiling from source, but it's pretty much a four step process:
1. Download the tarball and unpackage it. If it's *.tar.gz, type "tar -zxf tarball.tar.gz. If it's *.tar.bz2, type "tar -jxf tarball.tar.bz2.
2. Inside the new folder (created from unpackaging the tarball), run Here you can set options like PREFIX, and other pre-compilation settings.
3. Run make. 4. Now, install it. For a list of all pre-compile options available to you type: ./configure --help

When you set PREFIX, you are telling where to install the compiled program to. I'm saying to set this yourself so that there aren't any conflicts with your existing gcc, and so that it's easier to remove when you should no longer need it.

Personally, I like setting my prefix to /opt. (PREFIX=/opt/)
It's an unused directory - pretty much.

hii
sory for late,
after $make command the following error occurs.

decl.c: In function 'start_struct':
decl.c:4451: error: argument 'code' doesn't match prototype
ch-tree.h:736: error: prototype declaration
make[2]: *** [decl.o] Error 1

make[1]: *** [cc1chill] Error 2
make[1]: Leaving directory `/home/celil/Desktop/gcc-2.95.3/gcc'
make: *** [all-gcc] Error 2


how can i handle it ?
thanks.

do you really need RTlinux or can you do with
a multimedia kernel or some performance patches (Koliva?)
or even just tweaking kernel?

Try running make and make install as root.
