Hi, So, I eventually managed to install slackware (only packages for passing the host reqs, running jhalfs, and running the slackware package management system. The key point (I think) is that I haven't installed the package "gmp-5.0.5-x86_64-1", and that it does not prevent gcc to run, simply because libgmp.so.10.0.5 is also included in elflibs (actually, it is in one of Hazel Russmann's posts). And I get exactly the same error: /bin/sh ../libtool --tag=CC --mode=link gcc -g -O2 -version-info 3:0:0 -static-libstdc++ -static-libgcc -o libmpc.la -rpath /tools/lib abs.lo acos.lo acosh.lo add.lo add_fr.lo add_si.lo add_ui.lo arg.lo asin.lo asinh.lo atan.lo atanh.lo clear.lo cmp.lo cmp_si_si.lo conj.lo cos.lo cosh.lo div_2si.lo div_2ui.lo div.lo div_fr.lo div_ui.lo exp.lo fma.lo fr_div.lo fr_sub.lo get_prec2.lo get_prec.lo get_version.lo get_x.lo imag.lo init2.lo init3.lo inp_str.lo log.lo log10.lo mem.lo mul_2si.lo mul_2ui.lo mul.lo mul_fr.lo mul_i.lo mul_si.lo mul_ui.lo neg.lo norm.lo out_str.lo pow.lo pow_fr.lo pow_ld.lo pow_d.lo pow_si.lo pow_ui.lo pow_z.lo proj.lo real.lo urandom.lo set.lo set_prec.lo set_str.lo set_x.lo set_x_x.lo sin.lo sin_cos.lo sinh.lo sqr.lo sqrt.lo strtoc.lo sub.lo sub_fr.lo sub_ui.lo swap.lo tan.lo tanh.lo uceil_log2.lo ui_div.lo ui_ui_sub.lo -lmpfr -lgmp -lm libtool: link: warning: library `/usr/lib64/libmpfr.la' was moved. libtool: link: ar rc .libs/libmpc.a abs.o acos.o acosh.o add.o add_fr.o add_si.o add_ui.o arg.o asin.o asinh.o atan.o atanh.o clear.o cmp.o cmp_si_si.o conj.o cos.o cosh.o div_2si.o div_2ui.o div.o div_fr.o div_ui.o exp.o fma.o fr_div.o fr_sub.o get_prec2.o get_prec.o get_version.o get_x.o imag.o init2.o init3.o inp_str.o log.o log10.o mem.o mul_2si.o mul_2ui.o mul.o mul_fr.o mul_i.o mul_si.o mul_ui.o neg.o norm.o out_str.o pow.o pow_fr.o pow_ld.o pow_d.o pow_si.o pow_ui.o pow_z.o proj.o real.o urandom.o set.o set_prec.o set_str.o set_x.o set_x_x.o sin.o sin_cos.o sinh.o sqr.o sqrt.o strtoc.o sub.o sub_fr.o sub_ui.o swap.o tan.o tanh.o uceil_log2.o ui_div.o ui_ui_sub.o libtool: link: ranlib .libs/libmpc.a /bin/sed: can't read /usr/lib64/libgmp.la: No such file or directory libtool: link: `/usr/lib64/libgmp.la' is not a valid libtool archive make[5]: *** [libmpc.la] Error 1 make[5]: Leaving directory `/mnt/lfs/sources/gcc-build/mpc/src' make[4]: *** [all-recursive] Error 1 make[4]: Leaving directory `/mnt/lfs/sources/gcc-build/mpc' make[3]: *** [all] Error 2 make[3]: Leaving directory `/mnt/lfs/sources/gcc-build/mpc' make[2]: *** [all-mpc] Error 2 make[2]: Leaving directory `/mnt/lfs/sources/gcc-build' make[1]: *** [all] Error 2 make[1]: Leaving directory `/mnt/lfs/sources/gcc-build' Adding --with-gmp-include=$(pwd)gmp --with-gmp-lib=$pwd/gmp/.libs *does not help*. Actually, I wonder whether it would not be cleaner to use host gmp, mpfr and mpc completely, for building gcc pass1. Those libraries are installed anyway with recent gcc. The only requirement would be that the headers be installed too. Well, I have just read the thread "GCC build first pass: mpc build looks for libgmp.la in the wrong place" to the end (should have done that before, I know!). Basically, the build only fails when libmpfr.la is on the host and libgmp.la is not. But if any is on the host, the build system uses paths on the host. I'll try to reproduce this on Debian.
