vexriscv.MuraxSim error in Windows 10 using the latest github clone

[flylandcs]

after SpinalSim + Verilator windows setup according to https://spinalhdl.github.io/SpinalDoc/spinal/sim/introduction/

sbt "test:runMain vexriscv.MuraxSim" (using the latest github clone)

I got the following error: ... [info] [Progress] Simulation workspace in C:\Dev\VexRiscv.\simWorkspace\Murax [info] [Progress] Verilator compilation started [error] Nonzero exit code returned from runner: -1073741819 [error] (Test / runMain) Nonzero exit code returned from runner: -1073741819

stepping into the code, it crashed in "VerilatorBackend.scale" at the following line: val nativeInstance: IVerilatorNative = nativeImpl.newInstance().asInstanceOf[IVerilatorNative]

nativeImpl.newInstance() will load "verilator_1.dll", which does exists. I don't have any clue on why calling nativeImpl.newInstance() will crash. Since nativeImpl is dynamically compiled, I cannot debug it further.

BTW, the SpinalSim + Verilator windows setup instruction may not be complete on some systems. I have two additional findings:

1) In C:\Program Files\Java\jdk1.8.0_201\include\win32\jni_md.h , I added "typedef int64_t __int64;" in order to compile

2) I have to use "export CPLUS_INCLUDE_PATH=/mingw64/include/c++/9.2.0:$CPLUS_INCLUDE_PATH" to solve stdlib.h issue.

hmm was working on W7.

about 1) I should be able to workaround that 2) weird :/ Anyway, thanks for the info !

@flylandcs Now trying to fix that in SpinalHDL

workaround the __int64 by having the following in the main cpp file :

#include <stdint.h>
#include <string>
typedef int64_t __int64;
#include <jni.h>

Didn't hit the stdlib.h issue, but :

#

What's a paine in the ass ^^

ahh by reinstalling msys that was with verilator 4 that is now fine

[Dolu1990]

So at the end in my case, the only things 1) and 2) were not required, my step is :

• W10
• msys64 with https://spinalhdl.github.io/SpinalDoc-RTD/SpinalHDL/Simulation/install.html#from-the-mingw-packet-manager
• OpenJDK 13

In my case. There is a problem with the dll file in icarus verilog. change path ;C:\msys64\usr\bin;C:\msys64\mingw64\bin;c:\iverilog\bin
