I would check if ./configure for GiNaC gives messages like checking for flex ... no checking for lex ... no If that is the case, you need to install flex before you build GiNaC. Slawek

----- 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?

Thanks,

Baruch Feldman
