Hi! Maybe someone with Cygwin experience can help here? ----- Forwarded message from Baruch Feldman <baruch_feldman@yahoo.com> ----- Dear Mr. Bauer, [...] I wanted to install GiNaC on my (windows) machine so that I could do calculations, etc. I haven't had a lot of experience with Gnu installations before. I basically downloaded both Cygwin and CLN in order to install GiNaC. The other two installations seemed to go OK, but with GiNaC I got the error message below. (I have no idea how to interpret this). Perhaps I put the files in the wrong place -- I wasn't sure where to put them so I put the GiNaC directory under lib. Do you know how to get around this problem?
