Hi guys, I'm building clfs 2.1 on 64-bit host (Ubuntu) for 32-bit Atom target.
While building gmp in ch.5.9 I have to add ABI=32 as stated in the book: configure: summary of build options: Version: GNU MP 5.1.3 Host type: core2-unknown-linux-gnu ABI: 32 Install prefix: /cross-tools Compiler: gcc -std=gnu99 Static libraries: no Shared libraries: yes Later on in ch.5.12 configure failed for ISL-0.12.1. In the log I see: ... configure:17164: checking for main in -lgmp configure:17183: gcc -o conftest -O3 -fomit-frame-pointer -malign-double -fstrict-aliasing -ffast-math -I/cross-tools/include -L/cross-tools/lib -Wl,-rpath,/cross-tools/lib conftest.c -lgmp -lgmp >&5 /usr/bin/ld: skipping incompatible /cross-tools/lib/libgmp.so when searching for -lgmp /usr/bin/ld: cannot find -lgmp /usr/bin/ld: skipping incompatible /cross-tools/lib/libgmp.so when searching for -lgmp /usr/bin/ld: cannot find -lgmp collect2: ld returned 1 exit status ... configure:17192: result: no configure:17202: error: gmp library not found After googling found: > I suspect that the problem may be that the libraries are for 32-bit > when you are attempting to build a 64-bit compiler, or vice versa. > I was able to build GCC 4.5.1 on MacOS X 10.6.4 recently, but I > built and installed the GMP, MPFR and MPC libraries myself - > in /usr/gnu64 (a non-standard location that I use for stuff that I install > for my own benefit). I also used the configuration option: > CC='gcc -m64' Since there was a recommendation to set ABI=32 for configuring gmp, is something needed for ISL as well in order to succeed?
