<snip> FYI: building them in the tools directory is going to be problematic. During the stage 1 build of gcc, the make system is unable to locate the libmpfr.so.1 library, and so aborts. I'm not familiar enough with the convoluted logic of the compiler makefile magic, so not sure of how to add /tools/lib to the compilation - no amount of configure (--with-gmp, --with-mpfr), LDFLAGS (-L/tools/lib) or other magic has so far allowed that path to make it to the stage1 build process from toplevel. It may be necessary to use the older "save binutils dir" and have a LIB_PATH of /tools/lib and /usr/lib, then clean and remove /usr/lib during the toolchain adjustment steps. (I'll try this method anyway, just to see if it works). I'll experiment some more, but it's likely that unless I get lucky, I'll revert to the known working method of adding the needed libraries to the host toolset. At some point this will need to be addressed, if nothing else for sucessful building from the LFS6.3 LiveCD, which doesn't have these libraries. -- -- - Steve Crosby -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
