Hi,
I finally managed to compile lapackpp 2.4.13 on Apple Darwin 8.7.0,
since it's been a lot of trouble to me I thought I'd post how I've
done it hoping it will be useful to others.

First you need to install g77 and gcc-4 from fink (gcc4 from apple
didn't work)


set FLIBS="-L/sw/lib/gcc4/lib/gcc/powerpc-apple-darwin8/4.0.2/ -L/sw/
lib -lm -lfrtbegin -lSystemStubs -lSystem -lmx /sw/lib/gcc4/lib/gcc/
powerpc-apple-darwin8/4.0.2/libgcc.a"

and run the configure script in the following way
./configure --with-blas='-framework vecLib' --with-lapack="-framework
vecLib" CC=/sw/bin/gcc-4

after that you can run make and make install

To use lapackpp on Xcode you will need to disable the "Allow
Zerolink" option (if enabled) under the build menu
then set "Other C++ flags" and "Other Linker flags" to have value "-L/
usr/local/lib -llapackpp". Last thing set the "Header search path" to
value "/usr/local/include/lapackpp/"

and you are all set.

let me know if you want the binaries.

Thanks again for your time,

Fabio Franconeri.
