Hi

Compiling ITK 4.12.2 with the windows-x64 image fails with the following error:

In file included from /work/XRTK-windows-x64/CXX/XRTK-build/ITK/Modules/ThirdParty/VNL/src/vxl/core/vnl/Templates/vnl_matrix+long_double-.cxx:1:0:

The issue (or at least a very similar one) is discussed in this thread on the gcc bugtacker and fixed in gcc 5.0.0.

I understand that simply upgrading gcc might brake other peoples builds, but perhaps alternative versions of gcc could be provided via update-alternatives or similiar? Is this possible?

The add-apt-repository command is not available and modifying /etc/apt/sources* gives permission denied even when using sudo so it is difficult to upgrade gcc manually.

Perhaps #169 is related.

Hi @kaspermarstal ,

internal compiler error:

Most of the time these days, when you see this error, it indicates that the compiler ran out of memory. To avoid it, reduce the parallelism of the build by passing -j4 to make or ninja, etc.

I tried building ITK 4.12.2 with the current image, and it succeeded.

That said, #172 will update the toolchain to use GCC 5.4.0. I verified that ITK builds with this version, too.

Hi,

Thanks for the suggestion! It wasn't an out-of-memory error but using GCC 5.4.0 did the trick!
