For our - purposes these headers will not be needed. This switch prevents - GCC from looking for them. - - - - - --disable-shared - - This switch forces GCC to link its internal libraries - statically.

These features - will fail to compile when building a cross-compiler and are not - necessary for the task of cross-compiling the temporary libc. - - - - - --disable-multilib - - On x86_64, LFS does not yet support a multilib configuration. - This switch is harmless for x86. - - - - - --enable-languages=c,c++ - - This option ensures that only the C and C++ compilers are built. - These are the only languages needed now. - - - - - - Compile GCC by running: - -make - - Install the package: - - make install - - This build of GCC has installed a couple of internal system - headers. Normally one of them, limits.h, would in turn - include the corresponding system limits.h header, in - this case, $LFS/usr/include/limits.h. However, at the - time of this build of gcc $LFS/usr/include/limits.h - does not exist, so the internal header that has just been installed is a - partial, self-contained file and does not include the extended features of - the system header. This is adequate for building glibc, but the full - internal header will be needed later. Create a full version of the internal - header using a command that is identical to what the GCC build system does - in normal circumstances: - -cd .. -cat gcc/limitx.h gcc/glimits.h gcc/limity.h > \ - `dirname $($LFS_TGT-gcc -print-libgcc-file-name)`/install-tools/include/limits.h - - - - - - <para>Details on this package are located in - <xref linkend="contents-gcc" role="."/></para> - - </sect2> - -</sect1> -- cgit v1.2.3-54-g00ecf
