Summary: waveOutGetDevCaps problem
Initial Comment:
Using mingw32ce-0.10.0.20070208-cygwin
There's a problem with waveOutGetDevCaps - mmsystem.h defines
waveOutGetDevCapsA and waveOutGetDevCapsW, but libcoredll.a exports only
waveOutGetDevCaps.
If I do
---
#undef waveOutGetDevCaps
extern "C" MMRESULT WINAPI waveOutGetDevCaps(UINT,LPWAVEOUTCAPSW,UINT);
---
in my source, waveOutGetDevCaps works.
Regards,
Carsten Sorensen

Scratch that - that section is probably fine.
The problem is that mmsystem.h still declares waveOutGetDevCapsA and
waveOutGetDevCapsW as function prototypes - but not waveOutGetDevCaps.
I'm at a loss to explain why your example compiles :-/ ... perhaps because
I define _WIN32_WCE on the command line?

Hmm still no go.
g++ -o WaveOutDevice.o -c -O3 -Wall -Wno-unused-variable
-D_WIN32_WCE=0x0300 -I/Users/cso/code/oldsk00l/library WaveOutDevice.cpp
WaveOutDevice.cpp: In member function 'virtual bool
Oldsk00l::CWaveOutDevice::Open()':
WaveOutDevice.cpp:94: error: 'waveOutGetDevCaps' was not declared in this
scope
Note that I define _WIN32_WCE on the command line when calling g++ ...
This section in mmsystem.h looks all backwards to me
#ifndef _WIN32_WCE
#define waveOutGetDevCaps waveOutGetDevCapsW
#define waveOutGetErrorText waveOutGetErrorTextW
#define waveInGetDevCaps waveInGetDevCapsW
#define waveInGetErrorText waveInGetErrorTextW
#else
#define waveOutGetDevCapsW waveOutGetDevCaps
#define waveOutGetErrorTextW waveOutGetErrorText
#define waveInGetDevCapsW waveInGetDevCaps
#define waveInGetErrorTextW waveInGetErrorText
#endif

Sorry for that,
Please try the new attached patch.
Tested by buiding this:
#include <windows.h>
#include <mmsystem.h>
int main ()
{
waveOutGetDevCaps (0,NULL,0);
return 0;
}
File Added: mmsystem.h.2.diff

I grabbed the newer of the two diffs. There are new problems - when
including mmsystem.h now, I get
g++ -o WaveOutDevice.o -c -O3 -Wall -Wno-unused-variable

Hi Carsten,
Thanks for reporting.
It looks like there are other functions with the
same problem, so I fixed them too. Please could you
try the attached patch to mmsystem.h?
Cheers,
Pedro Alves
