Hi; As a follow up to my comments on python and MSVC versions, I think a starting point to fix the build problem correctly would be to add something like this in main/python/makefile.mk (around line 127) # Requires adapting for according to the MSVC compiler version.# Normally PCBuild will carry the latest supported build files..IF "$(CCNUMVER)" <= "00150030729"BUILD_DIR=PC/VS9.0.ELSEBUILD_DIR=PCBuild.ENDIF _____ There is no VS/10.0, at least not for python 2.7.x, as I had thought previously, and we shouldn't worry about any MS Visual C++ older than 2008. Yes, I realize this involves boring rework, but that's the way the python documentation suggests. Cheers, Pedro. * The numering is based on:https://en.wikipedia.org/wiki/Microsoft_Visual_C%2B%2B
