Fixed bug #216
The attached files allow building the SDL library and tests with the Open
Watcom compiler for Windows:
- static library or DLL
- Debug or Release builds available
- uses register calling convention of Open Watcom
- wmake target to build the SDL test samples
Following is a table that shows what works and what doesn't, yet:
checkkeys +
graywin +
loopwave +
testalpha +
testbitmap +
testdyngl +
testerror +
testfile +
testgamma +
testgl +
testhread +
testiconv - (all failed)
testkeys +
testlock + (after removing calls to raise() from signal handler)
testoverlay + (needs 'set SDL_VIDEODRIVER=directx')
testoverlay2 + (-"-)
testpalette +
testplatform +
testsem +
testsprite +
testtimer +
testver +
testvidinfo +
testwin - (fading doesn't seem right)
testwm +
torturethread +
testcdrom +
testjoystick not tested
threadwin +
TODO:
- make stack calling convention work (has linking issues with dxguid.lib)
- perform testjoystick (I don't have a joystick)
- investigate fading in testwin
- merge with OS/2 port
- add DOS target
