Hi
Thanks all for the replays.
I am trying to create a cross compiler using the steps for building LFS
when the temporary tools are build.
Those steps should allow me to use the cross compiler, but obviously
i am not doing something correctly.
I just used the path from cross-tools package 0.43
but not using anything from there. One reason for which i am trying
to create the cross compiler, is that i saw you build for LFS gcc 4.8.2
and glibc-2.19, which are not supported anymore by that tool or others.
This are the steps is used. I didnt created a lfs user,
but if you think thats the cause of the problem i can create it and try
that way as well. The host is x86_64 with kernel 3.7.10
I have a symlink between:
ls -ld /tools
lrwxrwxrwx 1 root root 47 Apr 17 08:08 /tools ->
/home/marian/crosstool/x86_64-unknown-linux-gnu/
export PREFIX=/home/marian/crosstool/x86_64-unknown-linux-gnu
export TARGET=x86_64-unknown-linux-gnu
export
SYSROOT=/home/marian/crosstool/x86_64-unknown-linux-gnu/x86_64-unknown-linux-gnu/sys-root
export PATH=/tools/bin:/bin:/usr/bin
1. Binutils
../binutils-2.24/configure --prefix=/tools --with-sysroot=$SYSROOT
--with-lib-path=/tools/lib --target=$TARGET --disable-nls
--disable-werror
binutils compiles fine. no errors.
2. Kernel headers
make headers_check
make INSTALL_HDR_PATH=dest headers_install
cp -rv dest/include/* /tools/include
3. From some other docs i saw they install the glibc headers as well here.
I have tried this, but the same error is happening when building gcc or
glibc.
System glibc headers
mkdir glibc-build
cd glibc-build
../glibc-2.19/configure --prefix=/tools --host=$TARGET
--build=$(../glibc-2.19/scripts/config.guess) --disable-profile
--enable-kernel=2.6.32 --with-headers=/tools/include
libc_cv_forced_unwind=yes libc_cv_ctors_header=yes libc_cv_c_cleanup=yes
--without-selinux
make -k install-headers install_root=/
4. GCC stage 1
../gcc-4.8.2/configure --target=$TARGET --prefix=/tools
--with-sysroot=$SYSROOT --with-newlib --without-headers
--with-local-prefix=/tools
--with-native-system-header-dir=/tools/include --disable-nls
--disable-shared --disable-multilib --disable-decimal-float
--disable-threads --disable-libatomic --disable-libgomp --disable-libitm
--disable-libmudflap --disable-libquadmath --disable-libsanitizer
--disable-libssp --disable-libstdc++-v3 --enable-languages=c,c++
--with-mpfr-include=$(pwd)/../gcc-4.8.2/mpfr/src
--with-mpfr-lib=$(pwd)/mpfr/src/.libs
Here if i use make, i get the same error, that compiler can not create
executables. From config log, the error is that cross gcc is not able
to find a couple of libs (which seems generated by glibc) crt1.o, crti.o,
crtn.o and libc.so
Thus from other docs i have seen these being used, so i have tried to
continue using them:
make all-gcc
make all-target-libgcc
make install-gcc
make install-target-libgcc
5. building glibc fails building in sunrpc folder,
for some rpc_* files, with the same same error, saying that those libs can
not be found.
../glibc-2.19/configure --prefix=/tools --host=$TARGET
--build=$(../glibc-2.19/scripts/config.guess) --disable-profile
--enable-kernel=2.6.32 --with-headers=/tools/include
libc_cv_forced_unwind=yes libc_cv_ctors_header=yes libc_cv_c_cleanup=yes
--without-selinux
