hi guys,,

i am doing kernel compilation by using kenel 3.4-rc4.
i have successfully installed ncurses5.9,gmp-5.0.4,mpc-0.9,mpfr 2.4.2....
i have configured my new kernel also,,,now for making bzimage i need gcc compiler.

so i tries gcc4.7.0 and gcc4.6.2....but every time i give make command after extracting gcc,,,i get error:::

usr/lib/gcc-4.7.0/i686-pc-linux-gnu/libgcc:configure:error:cannot compute the suffix of object file:cannot compile.

i have changed the gcc version also,,tried atleast 5 times whole process..staring from recompiling of mpc,mpfr e.t.c....but still getting the same error..



plz help me to come out of this.

The error is misleading - look at your "config.log" for more details on what actually failed. You might be missing a dependency.

Look at these links:

* http://gcc.gnu.org/wiki/FAQ

* http://stackoverflow.com/questions/9...f-object-files
<= The root cause will be the same, whether you're building "gcc" or "libgcc"

Before you make gcc 4.7.0 you have to configure gcc. I recently configured my gcc 4.7.0 build using the following:
../configure --prefix=/tools --disable-nls --disable-shared --enable-static --wi thout-included-gettext --enable-static --enable-version-specific-runtime-libs\
--without-x --exec-prefix=/usr --sysconfdir=/etc --disable-multilib --disable-d ecimal-float --disable-threads\
--disable-libmudflap --disable-libssp --disable-libgomp --disable-libquadmath - -enable-languages=c --without-ppl --without-cloog\
--enable-threads-posix --disable-win32-registry --with-gmp=/usr/local --with-mp fr=/usr/local --with-mpc=/usr/local --with-target=mingw32

also, gcc -v will show you how your current gcc was configured.

ok let me check and thanks for ur help

Which Linux OS are you using ? ?

Be aware that gcc requires a build folder outside the gcc-4.7.0/ source.
So the configure line will start this way : ../gcc-4.70/configure --

A build example http://nosemaj.org/debian-gcc-4-7

thanks buddy

hi buddy,,

let me tell u what my problem is::
i have been given a project in which i have to develop a customized linux distribution for my college on which all the device drivers for hyperterminal, video conferencing and other communication softwares which generally run on windows should run on my linux os also..this is the aim of my project..

problem::
i have very less knowledge on linux..i have just started few day back working on linux..regarding my first linux compilation,,i am using boss(bharat operating sysytem)2.6.39 as my base os,,i downloaded linux kernel 3.4 latest and have configured it.after that i have compiled gmp, mpc, mpfr..but gcc 4.7.0 is not getting installed on the os. i am getting the error cannot compute suffix....i have tried everything for the last three days but the same error is coming up again and again..till the time gcc will not get compiled on my system i will not be able to build bzimage of my new kernel .

plz help me out.

GCC isn't difficult to build, but you will have to follow some very strict build rules.

How does your configure line look like ? Please show.
