%description
The GNU Scientific Library (GSL) is a collection of routines for
numerical analysis, written in C.

The library is available as 32-bit and 64-bit.


%package devel
Summary: Static libraries and header files for GSL development
Group: Development/Libraries
Requires: gsl = %{version}-%{release}
Requires: info
Requires: /sbin/install-info

%description devel
The gsl-devel package contains the header files and static libraries
necessary for developing programs using the GSL (GNU Scientific
Library).

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "xlc -q64" or "gcc -maix64".

%setup -q


%build
# setup environment for 32-bit and 64-bit builds
export AR="ar -X32_64"
export NM="nm -X32_64"

# first build the 64-bit version
export CC="xlc -q64"
./configure \
    --prefix=%{_prefix} \
    --infodir=%{_infodir} \

cp .libs/libgsl.so.0 .
cp cblas/.libs/libgslcblas.so.0 .
