Couldn't find a solution, Cmake version 3.10.2

Thanks!

Hi 0x57

what is your environment?
You are using Linux ? If so , which version?

I am confused though
I did a search
tlsh_unittest.cpp does not have a statement with new long in it.

The codebase does not use "long" integers

$ grep -r "long" /.h /.cpp
Windows/WinFunctions.cpp: printf("ERROR: directory name candidate, %s, is too long (%d >= %d)\n",
test/timing_unittest.cpp: long before_ms;
test/timing_unittest.cpp: long after_ms;
test/timing_unittest.cpp: long diff = (after_ms - before_ms);
test/timing_unittest.cpp: long per_iter = diff / MAX_TRY;

cheers

Hey Jono,

Thanks for your prompt reply. I'm using Ubuntu with 4.15.0-50-generic.

Maybe you don't use long integers, but you refer to a function in cmake that does, and the linking fails?

I know nothing about how cmake works, but from my googling (cmake undefined reference to) I see that similar issues were resolved by fixing the order of the linked libraries / adding correct links.

Thank you

I will fire up an Ubuntu instance - and see what happens...
Give me a few days at this end to see what I can figure out...

Hi,

build fails on windows, however, due to some other undefined references in tlsh_unittest :

my believe is that the tslh.dll might not be properly linked:

Could you please suggest a solution?
Thanks

Please look my project if you still get LNK2019 error. I fixed that but didn't published on github due to limits of git lfs on github also I need remove archive for that etc. I solved that problem.
