gcc compilation error


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.

Which Linux OS are you using ? ?
http://www.linuxquestions.org/linux/...Ask_a_Question
http://linuxsilo.net/docs/smart-questions_en.html


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

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.
