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
