Compiler error on OSX Mavericks about simkernel

[dherkova]

Yes, I tried with the new version dherkova/SimKernel@de82d1eb0d0a76860b46b2ce4cdf3865101d654 . Actually you might be able to reproduce the issue if you compile with -stdlib=libc++ in your CFLAGS. The errors should appear before any calls to boost or gsl are made.

Hi, i am only having an Mac OS multiprocessor machine here on which i am running long simulations,
everything compiles perfectly on Mac OS 10.5.8 after i changed the computer time readout routine, I dont
have a new Mac OS at hand to test compilation there unfortunately...

[dherkova]

Ok, some updates. I managed to replicate the issue in an x86_64 ubuntu-based system compiling with clang and libc++.
But most importantly, I think I fixed the issue. It seems that libc++ doesn´t allow forward declarations involving the std library. I moved the definition of the class ExpressionPtr before typedef str::deque<ExprPtrT> ExprArgT; and the issue appears to be fixed. I will check again tomorrow on OS X and pull in case it also works there.

the error message sounded like this, so seems to be a valid fix, might make the code less ordered, but ok...

[dherkova]

Ok, issue solved!
Since it messes up the code a little bit and you might think of a better solution I just created a branch on my fork. See the commit here: dherkova/SimKernel@be928f3c17cbd0ad9df3cb3195bb0a11cc224b38

merge should have fixed this issue now...
