Hi - I am trying to access the NI488.2 framework (the equivalent to ni488.dll on Windows or libgpibapi.so on Linux) on a Mac from Java using Java Native Access. In order to do this, I need a .dylib, which is unfortunately not provided by NI.
To compile the required .dylib myself in XCode (Mac OS 10.6), I tried to build a C++ dynamic shared library following the programming examples listed in NI-488.2 manual, which is essentially to include ni488.h and include the NI488.framework.
When building the results, the linker complains with this error message:
in /Developer/SDKs/MacOSX10.6.sdk/Library/Frameworks//NI488.framework/NI488, missing required architecture x86_64 in file
And here is where my expertise ends. I have noticed two slashes in the path name, but don't know what to do with that.
I get the same error message (with two slashes) when I compile the 'regular' C file listed below using cc main.c -framework NI488.
#include <stdio.h>
#include <NI488/ni488.h>
int main (int argc, const char * argv[]) {
// insert code here...
printf("Hello, World!\n");
int status = ibclr(4);
return status;
}
How can I get the code to compile? Does anybody already have a
ni488.dylib?
Thanks a lot,
Kurt
