compling kernel using gcc4

linuxmandrake · 09-29-2005, 05:27 PM

ebian:/usr/src/linux# make menuconfig
HOSTCC scripts/kconfig/mconf.o
scripts/kconfig/mconf.c:91: error: static declaration of 'current_menu' follows non-static declaration
scripts/kconfig/lkc.h:63: error: previous declaration of 'current_menu' was here
make[1]: *** [scripts/kconfig/mconf.o] Error 1
make: *** [menuconfig] Error 2
debian:/usr/src/linux#

why do i get those errors? is it not the correct kernel source i typed i
apt-get install kernel-source

Try from /usr/src not /usr/src/linux

debian:/usr/src# make menuconfig
make: *** No rule to make target `menuconfig'. Stop.
debian:/usr/src#

will make xconfig work?
I had the same error before my video drivers were in and menuconfig wouldnt work.....xconfig did.

Compile a 2.6.12 or newer kernel or use export CC=/usr/bin/gcc-3.3 maybe even gcc-3.4 depending on which is installed in the shell before starting. GCC 4.0 has problems compiling any kernels older than 2.6.12.

/usr/gcc is just a symbolic link to what ever version of gcc right? Because when I compiled vmware it said although the cc enviorment variable was set to 3.4 the kernel is using gcc4.0. And i need to setup some symbolic link. So basically i point /usr/bin/gcc to gcc3.4 right?

help! I just reinstalled gcc but it deleted the /usr/bin/gcc so now i dont have a link
debian:/home/sc# ls -s /usr/bin/gcc-3.3 /usr/bin/gcc
ls: /usr/bin/gcc: No such file or directory
92 /usr/bin/gcc-3.3

That is telling you that gcc 3.3 is not installed what does this show you?

Code:

ls -l /usr/bin/gcc*
lrwxrwxrwx  1 root root      7 2005-08-21 13:42 /usr/bin/gcc -> gcc-4.0
-rwxr-xr-x  1 root root  95416 2005-08-23 05:54 /usr/bin/gcc-3.4
-rwxr-xr-x  1 root root 102056 2005-09-24 12:19 /usr/bin/gcc-4.0
lrwxrwxrwx  1 root root     10 2005-08-21 13:42 /usr/bin/gccbug -> gccbug-4.0
-rwxr-xr-x  1 root root  16133 2005-08-23 05:51 /usr/bin/gccbug-3.4
-rwxr-xr-x  1 root root  16280 2005-09-24 12:10 /usr/bin/gccbug-4.0

To answer your question above yes it is just a symbolic link, you can either change the link or use the export command I suggested when compiling to make it use a different compiler.
