[Gretl-users] Installation on Mandriva2007

have been trying to install gretl 1.6.0 on a PC with an AMD64 processor running Mandriva 2007. In my most recent attempt I downloaded and unpacked gretl-1.6.0.tar.bz2. When I ran ./configure it failed because it couldn't find lapack. Here are the relevant lines from config.log: configure:24845: checking for LAPACK configure:24884: gcc -o conftest -I./lib/src -g -O2 conftest.c-L/usr/lib -llapack -lblas -lgfortran -lc -lc -lm >&5 /usr/bin/ld: skipping incompatible /usr/lib/liblapack.so when searching for -llapack /usr/bin/ld: skipping incompatible /usr/lib/liblapack.a when searching for -llapack /usr/bin/ld: skipping incompatible /usr/lib/liblapack.so when searching for -llapack /usr/bin/ld: skipping incompatible /usr/lib/liblapack.a when searching for -llapack /usr/bin/ld: cannot find -llapack collect2: ld returned 1 exit status configure:24887: $? = 1 configure: program exited with status 1 configure: failed program was: | /* confdefs.h. */ The relevant files in /usr/lib are: liblapack.a; liblapack.so; liblapack.so.3.0. I would appreciate any advice people could give. Robin Carter
