Hi Erik,
Thank you for the reply, but now I am even more
confused ;=()
This is the soundmgr_openal.cxx I have...
~/fg/fg7/simgear/source/simgear/sound$ cvs status soundmgr_openal.cxx
===================================================================
File: soundmgr_openal.cxx Status: Up-to-date
Working revision: 1.87
Repository revision:
1.87 /var/cvs/SimGear-0.3/source/simgear/sound/soundmgr_openal.cxx,v
Sticky Tag: (none)
Sticky Date: (none)
Sticky Options: (none)
And that contains the code, in function SGSoundMgr::load()
...
#if defined(ALUT_API_MAJOR_VERSION) && ALUT_API_MAJOR_VERSION >= 1
ALfloat freqf;
data = alutLoadMemoryFromFile(samplepath.c_str(), &format, &size,
&freqf );
freq = (ALsizei)freqf;
int error = alutGetError();
if (data == NULL || error != ALUT_ERROR_NO_ERROR) {
string msg = "Failed to load wav file: ";
msg.append(alutGetErrorString(error));
throw sg_io_exception(msg.c_str(), sg_location(samplepath));
return false;
}
#else
You mean ALUT_API_MAJOR_VERSION should NOT be defined,
or be less than 1???
The included file, through #include <AL/alut.h>, which in
my case is in /usr/include/AL/alut.h, contains :-
#define ALUT_API_MAJOR_VERSION 1
#define ALUT_API_MINOR_VERSION 1
Is this the WRONG alut.h??? But it all works fine
with the simple 'hello world' OpenAL sample code...
And doing 'make check' in SG/sound, openal_test1,
2, and 3, each seem to run ok...
And when I tried a compile using the 'alternative'
coded alutLoadWAVFile() I get a warning that this is
'depreciated', and get the SAME error exit
anyway... and the code changes, checking that
alutGetErrorString(error) returns a value is
only in this 'alternate' code...
As stated, getting confused... Is there anything
else I can try, check, install? As advised, it all
ran fine a week or so ago...
Regards,
Geoff.
