Dear all,
I am trying to compile GMSH4.8.1 under windows 10 64bit + VS2019. I used the OOC7.5 (by putting win64/vc14/lib and inc into GMSH folder) and the following errors displayed:
Severity Code Description Project File Line Suppression State

After I went back to OOC 7.4, the compile was successful.
Could anyone help me to take a look at this problem?
Thanks,

Hello Mr. Tang, have you solved this problem， I also encountered the same problem

I guess that this particular issue should be fixed in development branch of GMSH.

Finally, I switched to the occ version of 6.91, and there is no such problem.

hi, I would like to know if you don't mind...
How did you compile opencascade? using static build or shared?
I am using cmake and the static build is required for my project however it doesn't build any library in OCCT folder, as in the bind is empty and the libd folder is also empty.
on top of that I get an MSB3073 error.
