mingw C++ linker error: VISA on Windows 10

Hi

 

I tried to add VISA support on a small program on Windows 10, compiled with mingw (C++). But I have a problem with the linker who failed to link all the functions(error undefined reference to `LeaveCriticalSection@4')

 

My code (simplified)

#include "C:\Program Files (x86)\IVI Foundation\VISA\WinNT\Include\visa.
.....
ViSession defaultRM;
ViStatus status = viOpenDefaultRM(&defaultRM);
 if (status == VI_SUCCESS) {
  status = viOpen(defaultRM, "GPIB0::2::INSTR", VI_NULL, VI_NULL, &instr);
 } 
.....

The makefile

 

CXXFLAGS += -I/C/Progra~2/IVI~1/VISA/WinNT/Include
LDLIBS += -L/C/Windows/System32 -lvisa32

The error message:

Several functions was linked, but not all.

Any ideas ?

 

Thanks in advance

 Hello,

 Windows 10 is supported by NI VISA 15.5, but we don't support c++ : http://download.ni.com/support/softlib//visa/NI-VISA/15.5/Windows/readme.html

we only support c# with .NET

 

Best regards
