deal.II with TBB on Windows: problems with muparser (and image size)

[vdilecce]

In order to use deal.II with TBB on Windows, I found that I could not force DEAL_II_WITH_THREADS=ON due to lack of pthread on Windows. However, I managed to configure deal.II with TBB on Windows using precompiled TBB from here, with directory structure manually rearranged to help the CMake find module.

However, deal.II does not build, apparently due to problems with muparser:

Errors like these happen on many targets, both in debug and release: however, if deal.II is configured with DEAL_II_WITH_MUPARSER=OFF, build succeeds.

I wonder what could be the problem... maybe some library build order issue? (no problems on Linux, by the way).

Additionally, I report here that on Windows deal.II with external TBB (and without muparser) builds only in Release: in Debug, I get the LNK1248 error (debug library exceeds 4 GB). This a problem since applications using deal.II cannot be built in debug due to _ITERATOR_DEBUG_LEVEL mismatch (deal.II is built with flag /MDd in debug). I think I found a workaround for now by specifying DEAL_II_CXX_FLAGS_DEBUG="/O1" when configuring deal.II (that is, overwriting default flag /Od and generating therefore a smaller object, sort of mimicking a "RelWithDebInfo" configuration.

I didn't have any problems using Visual Studio 2019.
