I am looking at the Format function which is in util.cpp
This and few other functions have no mention anywhere in the documentation. Is there a place where all the available functions are listed and their parentage? This will help to know which files need to be included for a particular function to be used.
I have a file that uses the Format("%s","This is a test") function. Without the #include <core/core.h> I get a link time error on Format being undefined. On including <core/core.h> in my cpp file, I get
In file included from C:\MyApps\NIDAQ\NIDAQ.c:2:0:
C:\upp2625\uppsrc/core/core.h:39:20: fatal error: typeinfo: No such file or directory
compilation terminated.
and this is in Nidaq.c
#include "nidaqmx.h"
#include "core/core.h"
/**********************************************************************/
#define DAQmxErrChk(functionCall) if( DAQmxFailed(error=(functionCall)) ) goto Error; else
void MyTest()
{
return;
}
int32 Ni_ReadDI(int8 Dev, int8 Port, int32 *DI)
{
int32 error=0;
TaskHandle taskHandle=0;
uInt32 data;
char errBuff[2048]={'\0'};
int32 read;
//*********************************************
// DAQmx Configure Code
//*********************************************
DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
DAQmxErrChk (DAQmxCreateDIChan(taskHandle,
(const char *)(Format("Dev%c/port%c",Dev,Port)),
"",DAQmx_Val_ChanForAllLines));
...... irrelevant part snipped off
I'd appreciate any help I can get with this. For now, I'm stuck.
Regards

Actually I did not forget the namespace Upp, I had to keep it out for the files to compile, otherwise, the Nidaqmx.h and this one were fighting it out in real-time on my desktop 
the extern "C" was needed to keep the linker happy or it could not 'see' the functions in the other file. Anyway, now that I have something working, I'll 'try' to move on. Thanks again.

Hello Jerson
As NIDAQmx.h redefines int32, ..., I have included this before:
#define _NI_int8_DEFINED_
#define _NI_int16_DEFINED_
#define _NI_int32_DEFINED_
And remember that the namespace Upp is a must  .
Best regards
Iñaki

Hi Jerson,
I guess your linker can't find the libs because they are in directory that is not specified on the linker command line. I believe you can solve it by adding "New linker option" in Package manager that specifies the path. For gcc it would be "-L/path/to/the/libs", not sure about the MSVC syntax from the top of my head. If I am not mistaken, then relative path might work as well.
The include paths are actually something bit different, as they are used only during compiling to find #include files.

Koldo, Honza
Perfect. I used the Setup->Build methods to inform the linker about LIB directories and it works.
Thank you for your help
Where can I find info about the various goodies hidden inside the Upp namespace? This will be very helpful as I'm quite unaware of the hidden jewels in the framework.

Is there some kind of a function browser that can be handy? Is ^N the answer?

Ctrl+N, Ctrl+J and last, but not least F1 
Ctrl+N is good if you are interested in stuff from a distinct location (file or class).
Ctrl+J shows you everything (in currently included packages) and tells you where it is if you know how is it named.
F1 gives you details, at least for things that are documented.
Also Ctrl+G, but that is just Ctrl+J restricted to single file.

Just to understand, is the problem due to the nidaqmx.h file? - how? Was that causing the problems? I just cannot wrap my head around this as yet. Can you explain what could be the reason for the problems I see just so I can take adequate precautions in the future.
