I'm attempting to run configure for ppl-0.11 It fails to find gmp, even though I have installed gmp-4.3.2 (with --enable-cxx set) Both of these are the recommended versions in <src-dir>/gcc-4.7.2/gcc/doc/HTML/prerequisites.html ./configure --prefix=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64 --with-gmp-prefix=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64 --with-gmp=/hostname/tmp/syddev/sdk/gcc472/suse11/x86_64 configure: error: Cannot find GMP version 4.1.3 or higher. GMP is the GNU Multi-Precision library: see http://www.swox.com/gmp/ for more information. When compiling the GMP library, do not forget to enable the C++ interface: add --enable-cxx to the configuration options. (Note I tried both '--with-gmp' and '--with-bmp-prefix') If I look in the directory where I specified `with-gmp`, here is the installed gmp: $ grep MP_VERSION /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/include/gmp* /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/include/gmp.h:#define __GNU_MP_VERSION 4 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/include/gmp.h:#define __GNU_MP_VERSION_MINOR 3 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/include/gmp.h:#define __GNU_MP_VERSION_PATCHLEVEL 2 $ ls -l /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/include/gmp* -rw-r--r-- 1 syddev ausdev 84255 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/include/gmp.h -rw-r--r-- 1 syddev ausdev 114898 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/include/gmpxx.h $ ls -l /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmp* -rw-r--r-- 1 syddev ausdev 1047404 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmp.a -rwxr-xr-x 1 syddev ausdev 820 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmp.la lrwxrwxrwx 1 syddev ausdev 15 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmp.so -> libgmp.so.3.5.2 lrwxrwxrwx 1 syddev ausdev 15 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmp.so.3 -> libgmp.so.3.5.2 -rwxr-xr-x 1 syddev ausdev 397040 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmp.so.3.5.2 -rw-r--r-- 1 syddev ausdev 36524 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmpxx.a -rwxr-xr-x 1 syddev ausdev 894 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmpxx.la lrwxrwxrwx 1 syddev ausdev 17 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmpxx.so -> libgmpxx.so.4.1.2 lrwxrwxrwx 1 syddev ausdev 17 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmpxx.so.4 -> libgmpxx.so.4.1.2 -rwxr-xr-x 1 syddev ausdev 24587 2012-11-28 12:12 /hostname/tmp/syddev/sdk/gcc472/suse11/x86_64/lib/libgmpxx.so.4.1.2 Any help greatly appreciated Thanks Steve
