[Gsll-devel] gsll+clisp+cygwin

[Liam Healy]

Mirko,

My platform is Debian x86-64.  All libraries go in /usr/lib as in
other architectures.   So your conditionals

((:and :unix (:not :x86-64))
   (:or "/usr/lib/libgslcblas.so.0" "/usr/lib/libgslcblas.so"
	"/bin/cyggslcblas-0.dll"))
 ((:and :unix :x86-64)
   (:or "/usr/lib64/libgslcblas.so.0" "/usr/lib64/libgslcblas.so"))

breaks the path to /usr/lib because of the (:not :x86-64).  It turns
out that Debian actually has a /usr/lib64 which is just a link to
/usr/lib, but you shouldn't count on that link being there since
/usr/lib is the normal place to put libraries.   There is nothing
wrong with minimizing the number of conditionals; it is an ":or"
search path, so if it doesn't find it at the early locations, it just
keeps on searching.  Thus

(:unix
 (:or "/usr/lib/libgslcblas.so.0" "/usr/lib/libgslcblas.so"
"/bin/cyggslcblas-0.dll" "/usr/lib64/libgslcblas.so.0"
"/usr/lib64/libgslcblas.so"))

should work everywhere.  If there is a feature that indicates cygwin,
it might be better to separate that off into another conditional.
Please post *features* from your implementation.  Thanks.

Liam
