Cross-compiling on Linux for Windows via x86_64-w64-mingw32-g++

Dear all, first of all, I want to thank you all for this very nice piece of software. I am currently developing a Python package to wrap the finite element library oomph-lib in Python. GiNaC is required here to generate C code which is compiled on the fly to quickly assemble the weak forms which are defined in Python. In some sense, this is similar to the finite element library FEniCS, which also uses GiNaC, but oomph-lib provides better capabilities for multi-physics and ALE methods. My Python code works perfect in Linux, but as a long time goal, I also want to produce Python Wheels for Windows. However, I have a hard time to cross-compile GiNaC and CLN for Windows (64 bit). Does anyone has some experience with that? I am aware of the precompiled Windows binary, but they seem to be a bit out of date... I am grateful for any input. Best regards, Christian

Hello, I am currently doing an internship and we used GiNaC in our project to simplify expressions. my question is how I can generate a balanced expression tree from a ginac expression ?? (now I create expressions in form of a binary expression tree) Thanks and regards, Aimad
