Cosim testbench elaboration fails and psg_mpfr.dll and psg_mpir.dll not found

Hi,

I installed Quartus Prime Pro 19.4 along with HLS Compiler and ModelSim.

I'd like to start the HLS development, so I tried to build the examples.

However, build of the example "ac_fixed_math_library" fails. First, the command prompt returns error when running build.bat : "Error: Cosim testbench elaboration failed". This is the screen image of the command prompt.

I attach debug.log in this post.

Second, the generation of tutorial-x86 seemed successful, so I tried to execute it; however it fails due to lack of psg_mpfr.dll and psg_mpir.dll. This is the error screen:

This Japanese message reads like: "Cannot continue the execution of this code because psg_mpir.dll was not found. Reinstall of the program may resolve this problem". I reinstalled HLS compiler and ModelSim, but the problem was not solved.

Best regards,

Yoshitaka
