Hi Octavio,

This error is occurring in the build of the third party OpenCascade 0.17 library. It looks like the header file xlocale.h was removed from glibc with a recommendation to use locale.h instead (see https://sourceware.org/legacy-ml/libc-alpha/2017-08/msg00010.html, which I found via https://github.com/agracio/electron-edge-js/issues/16). I assume you’re using a very recent version of Ubuntu (I think you may have said in a previous message to the list that you’re using 20.04?)

Open Cascade 0.18.3 is packaged for Ubuntu so you should be able to just install the system packages and Nektar++ will detect them and won’t need to build OCE.

If install the package “liboce-ocaf-dev” (e.g. sudo apt-get install liboce-ocaf-dev) then this should install the necessary OCE packages to build Nektar++ with mesh generation support.

Regards,

Jeremy

Hi again,
I am trying to use the Mesh Generation option by setting the NEKTAR_USE_MESHGEN option to ON but when I try to compile it this pops up
