You probably did this already, but just to make sure, this is the order of building these things:

first do whatever upgrade to cygwin you want or need using the cygwin setup program

now do a clean compile/install of octave

now do a clean compile/install of octave-forge

I think you error messages might stem from compiling different bits of your setup with different compiler/library versions. Using the above order of building should eliminate this uncertainty at least.

I’ve been trying to get octave 2.1.57 + octave-forge 2004.07.07 working on my WinXP PC using a very recent download of Cygwin. Most things work well, and I am altogether hugely impressed. However, sadly, one of the packages in which I’m most interested, the symbolic package from octave-forge, is proving more stubborn, almost certainly because I don’t know how to build it properly. I have downloaded, built and installed cln-1.1.8, GiNaC-1.2.1, and octave-forge, and I did end up with a “symbols.oct” file on the appropriate path, along with a large number of “.oct” files symbolically linked to it. However, whenever I try to execute any of the functions in the symbols.oct, I get the message “error: dlopen: Win32 error 998”. I have a strong suspicion that something hasn’t linked correctly, meaning that symbols.oct is broken, and quite possibly, incomplete, but such is my ignorance I don’t have the slightest idea how to fix it. I could try rebuilding everything starting off with different options to the configure step, or, heaven forbid, start messing about with makefiles, but given the time it takes to build everything, it might be a very long time before I get anywhere.

All suggestions welcome, and all ridicule tolerated.
