I don't yet have the answer to which C++ runtimes are used. But I can provide the details about the project's g++ : $ which g++ /d/OPENPI~2/QtSDK/mingw/bin/g++ $ g++ -v Using built-in specs. Target: mingw32 Configured with: ../gcc-4.4.0/configure --enable-languages=c,ada,c++,fortran,java,objc,obj-c++ --disable-sjlj-exceptions --enable-shared --enable-libgcj --enable-libgomp --with-dwarf2 --disable-win32-registry --enable-libstdcxx-debug --enab le-version-specific-runtime-libs --prefix=/mingw --with-gmp=/mingw/src/gmp/root --with-mpfr=/mingw/src/mpfr/root --build =mingw32 Thread model: win32 gcc version 4.4.0 (GCC) At this point, I would like to know if the only solution is too make sure both projects are using the same toolchain. I hope not as this is a bit out of my league. Would it possible to "tweak" the project's toolchain or build process to become compatible with the SDK? If not, are there other alternatives? Is it in the SDK roadmap to support alternate toolchains ?
