This is how we generally build egcs; building -where srcdir == objdir should still work, but doesn't get -extensive testing. - -Second, when configuring a native system, either "cc" must be in your -path or you must set CC in your environment before running configure. -Otherwise the configuration scripts may fail. - -To configure egcs: - - % mkdir objdir - % cd objdir - % srcdir/configure [target] [options] - - -target specification - - egcs has code to correctly determine the correct value for - target for nearly all native systems. Therefore, we highly - recommend you not provide a configure target when configuring a - native compiler. - - target must be specified when configuring a cross compiler; - examples of valid targets would be i960-rtems, m68k-coff, sh-elf, etc. - - -options specification - -Use options to override several configure time options for -egcs. A partial list of supported options: - - - --prefix=dirname -- Specify the toplevel installation - directory. This is the recommended way to install the tools into a directory - other than the default. The toplevel installation directory defaults to - /usr/local. - - These additional options control where certain parts of the distribution - are installed. Normally you should not need to use these options. - - --with-local-prefix=dirname -- Specify the installation - directory for local include files. The default is /usr/local. - - --with-gxx-include-dir=dirname -- Specify the installation - directory for g++ header files. The default is /usr/local/include/g++. - - - --enable-shared -- Build shared versions of the C++ runtime - libraries if supported --disable-shared is the default. - - --enable-haifa -- Enable the new Haifa instruction scheduler in the - compiler; the new scheduler can significantly improve code on some targets. - --disable-haifa is currently the default on all platforms except the HPPA. - - --with-gnu-as -- Specify that the compiler should assume the GNU - assembler (aka gas) is available. - - --with-gnu-ld -- Specify that the compiler should assume the GNU - linker (aka gld) is available. - - --with-stabs -- Specify that stabs debugging information should be used - instead of whatever format the host normally uses. Normally GCC uses the - same debug format as the host system. - - --enable-multilib -- Specify that multiple target libraries - should be built to support different target variants, calling conventions, - etc. This is the default. - - --enable-threads -- Specify that the target supports threads. - This only effects the Objective-C compiler and runtime library. - - --enable-threads=lib -- Specify that lib is the - thread support library. This only effects the Objective-C compiler and - runtime library. - - --with-cpu=cpu -- Specify which cpu variant the compiler should - generate code for by default. This is currently only supported on the - RS6000/PowerPC ports. - - -Some options which only apply to building cross compilers: - - --with-headers=dir -- Specifies a directory which has target - include files. - --with-libs=dirs -- Specifies a list of directories which contain - the target runtime libraries. - --with-newlib -- Specifies that "newlib" is being used as the target - C library. This causes __eprintf to be omitted from libgcc.a on the - assumption that it will be provided by newlib. - - -Note that each --enable option has a corresponding --disable option and -that each --with option has a corresponding --without option. - - - -Last modified on December 2, 1997. |
