I tried to compile YaCAS as a windows DLL for my HP Jornada 720. I got a lot of errror of missing headers. It seems that there aren't the headers of standard-c-library in the HPC200 SDK. Any ideas?
The standard c library should be there, it'll be unix stuff that's missing.
If it's an open source app, try using PGCC to compile, or GCC to cross compile. Also check out Rainer Keuchel's software pages which describe tools that have been used to port unix apps to WinCE.
That's partly right. For example the header <sys/types.h> is not included in HPC SDK, but in VisualStudio there is. VisualStudio is the only thing, Microsoft accepted standards. I have read about crosscompiling with GCC but I don't want to try because it's very difficult. The best way should be to get the standard libraries and headers and add them to HPC SDK.
