Congratulations on this very impressive work.

Out of curiosity, how far away do you think it is from being at a beta stage that one can use to write non-critical work in ?

Thanks Laeeth,

It's not too far I think. When finally comes the time when I can test one or two new complex libraries without triggering new bugs it should be good enough.

At the moment I'm focusing on libraries that depend on Boost and are one order of magnitude more "sophisticated" than Qt, once they work the way out to usable state with any library may be in sight.

One open source library that might not be too tough but would have high value in the financial domain is Quantlib. (I don't think it is heavily templated, but I don't yet know the codebase well).


Also, I am embarrassed to confess that I still have trouble building calypso (although I can build LDC fine). Specifically some symbols not found during compilation. I can pull them out if helpful, but I have tried several times over the past months and it is different ones each time.

Missing symbols might be caused by your LLVM source tree having a different version from Arch's LLVM libraries. The changes made to LDC's CMake file are very primitive and won't check if the selected LLVM include/ and libraries match the one in LLVM_SOURCE_PATH added by Calypso. If you built and installed LLVM + Clang 3.6 yourself to /usr/local and if there's a different version from Arch packages in /usr, check that cmake got the right LLVM_CONFIG path with:

  $ cmake -LA |grep LLVM

If it didn't fix the value with $ cmake -DLLVM_CONFIG=/usr/local/bin/llvm-config ../Calypso

Which commit of Calypso should I use, and which versions of clang and llvm? I am using arch linux.

The versions are the ones in the README, i.e the 3.6 branch of LLVM, Clang and compiler-rt.

I'll add a note about the not very smart detection of LLVM libs, and if some of the instructions in the README are still confusing or incomplete please tell me.
