Build error: size of array is not an integral constant-expression

[Scott Miller]

Hi all,

I am wondering if anyone else has seen the build error below.  I'm compiling on a mac with openmpi compilers (gcc version 4.8.1).  The svn log does not show any changes to the 2 files listed since March 7 (cmake changes), and I'm using a cleaned cmake build directory.  

Thanks.

Ciao Scott,

yes, I have already seen this error. Are you using gcc-mp-4.8 from mac ports? I had the same problem with gcc 4.8, but not with 4.7.

Using mac ports gcc 4.7 solved our issue, but then you have to compile openmpi on your own, because what is passed with mac ports only uses gcc-4.7 for mpif77 and clang for mpicc and mpicxx.

Luca.

Hi Luca,

I am not using gcc-mp-4.8 from macports.  My non-mpi gcc is v.4.8.1 from http://hpc.sourceforge.net, and I use it to compile openmpi on my own.  I'll try playing around with compiler versions and see if I can find a work-around.

Hi,

As per Luca's suggestion, using gcc 4.7.1 was the solution.  The version of OpenMPI did not seem to matter.

They must be from the future. gcc v. 4.8.1 has yet to be released...


Given the fact that

"Build error: size of array is not an integral constan-expression"

was a regression that was briefly introduced in the development version
that later became 4.8.0, it gets even more interesting...

Best,
Matthias

Hi All

Im experiencing the exactly the same issue.
Im not sure how to use gcc4.7, my current vesion is gcc version 4.8.2 (MacPorts gcc48 4.8.2_2) .
How can I use gcc4.7 just for dealii?   I have other applications that need 4.8
any help is more than welcome
thanks

What version of deal.II are you using? This would appear to be fixed in the
current development sources.

If you're stuck with some version of deal.II, just replace the place in
geometry_info.h by the following:


template <int spacedim>
static void
alternating_form_at_vertices
(const Point<spacedim> *vertices,
Tensor<spacedim-dim,spacedim> *forms);

Best
W.
