Re: Help Linux Woes Help!!!

Thanks guys,

I've progressed a bit further but I'm stuck again.
I managed to install the rpm's and rtlinux bits and got to recompiling
the kernel but when I ran 'make xconfig' I got an error message like:
make -C scripts kconfig.tk
make[1]: Entering directory '/usr/src/linux-2.0.36/scripts
gcc -I/usr/src/linux-2.0.36/include -02 -fomit -frame -pointer -g -Wall
-c -o tkpa
rse.o tkparse.c
make[1]: gcc: command not found
make[1]: *** [tkparse.o] Error 127
make[1]: Leaving directory '/usr/src/linux-2.0.36/scripts'
make: *** [xconfig] Error 2

I have tried to find gcc on the disk and on the Redhat updates site
without success and in the README in /usr/src/ it says that you must
have a version of gcc at least as new as your kernel and also updated
'binutils' which are also eluding detection. Can you offer any clues
please.
Incidentally, I'm quite impressed with what I've seen of linux so far -
once we get over these teething troubles I can see I'm going to form a
good relationship with it. For info, I'm now running it on a Pentium
100MHz with 64Mb of RAM and with linux on a 4.3Gb disk and Windows '95
dual booting on a 0.5Gb partition (actually a different disk drive)
using lilo as boot manager.
Thanks.
