I'm trying to install igraph-0.5.3 on
Cygwin and got the error regarding fabsl(). I found the posts from
the past regarding installing the GMP library so that it won't compile
the included files that reference fabsl, but even though I install the
GMP libraries, ./configure doesn't seem to be finding it and thus it keeps
trying to compile the source code that uses fabsl and thus fails. Am
I missing something? I tried pulling down the GMP library from Cygwin
under 'Math' as well as then finding and installing some precompiled cygwin
GMP binaries from the web. I guess I can compile GMP myself from
source but I was hoping to not have to jump through that hoop.
