I get the following error when compiling a file:

I think this may have to do with the SSE2_SHUFF being unsigned in random_dsfmt.h. Let me see if I can do some debugging.
Replacing SSE_SHUFF with 27 solves the problem, though I don't know if that is right. This may also be connected: https://stackoverflow.com/questions/48726032/using-a-variable-to-index-a-simd-vector-with-mm256-extract-epi32-intrinsic

Ok, so removing SSE2_SHUFF and replacing the entry with 0x1bU directly works. I will use this fix in Debian.
Hi
I have solved recently a similar issue that generated errors when IT++ is compiled on Ubuntu Bionic. You can find the relevant change here: https://sourceforge.net/p/itpp/git/ci/bb5c7e95f40e8fdb5c3f3d01a84bcbaf76f3676d/tree/itpp/base/random_dsfmt.h?diff=d425a09330ced7aa8192d695df9d38876df6c76d
I've uploaded a new version of IT++ to Debian with the above patch. Thanks.
After downloading this revesion it managed to build, however, when I am not able to do the testing.

Hi
gtest sources need to be downloaded separately in your gtests folder before you start the actual compilation.

Bogdan
Could you please send me the link? I downloaded it from github but I am still getting the same error message.
Many thanks.
Regards.
Hi
Here are the steps I have used:
Note that GTEST_DIR does not point to the sources root folder (when googletest is cloned with git) but goes one level lower where only googletest sources are.
In order to run the tests use (from build folder)
Worked smoothly.
Thanks a lot.
Have a great evening.
