which gcc to use

masand · 01-07-2005, 04:26 AM

i have downloaded packages for LFS 6.0

now it has gcc version 3.4.1

i have 2 linux OS
fedora core 2--gcc version 3.3.3
mandrake 10.1--gcc version 3.4.1

i am more on FC2 than mandrake

and i want to compile LFS on FC2 , but i fear the gcc version.
last time i tried compiling LFS on RH9 whcih had different gcc version. i could bot go with gcc
so i want to know that would the different gcc version be a problem or should i go with mandrake

Well since the real work happens after the chroot, you would probably be ok, however, you'd be better off from the get go if you had identical GCC versions. You can always have 2 compilers on FC if you'd like, just be sure to change your GCC= to the path of the compiler you want to use.

Cool

even before you chroot, your path will pick up the temporary tools gcc first (which is completely static) anyway. So it shouldn't make any difference.

thanks for the reply
so will it not matter if i install another gcc
i just need to put that in PATH..

One of the first things you do is create the /tools directory (which is actually located on the new partition) and set the path to search /tools/bin before anything else. so /tools/bin/gcc will be executed instead of /usr/bin/gcc.

thans for ur replies!
meanwhile i got the gcc-3.4.1 and i have replaced the older one by this , i have replaced the cpp ,libgcc, and gcc packages

do i need some more packages to be replaced?

replaced?

do you mean you replaced the host system compiler and libs?

masand · 01-07-2005, 10:58 PM

yes

i upgraded the gcc compiler and cpp and libgcc packages on the host system

ok, but what i was referring to was the gcc on the host does not matter. Once you build the temporary compiler in the bootstrap phase (which is compiled static so it won't use shared libs), you will not need the host compiler any longer.

thanks of the info
i am presently compiling the packages for LFS and they have not posed any problems as such
