libao-1.0.0 has native IRIX support, but fails to build with lots of errors such as: cc-1018 cc: ERROR File = ../../../include/ao/ao_private.h, Line = 141 An unmatched left parentheses "(" appears in an expression. #define adebug(format, args...) {\ ^ cc-1018 cc: ERROR File = ../../../include/ao/ao_private.h, Line = 155 An unmatched left parentheses "(" appears in an expression. #define averbose(format, args...) {\ ^ cc-1018 cc: ERROR File = ../../../include/ao/ao_private.h, Line = 169 An unmatched left parentheses "(" appears in an expression. #define ainfo(format, args...) {\ ^ cc-1018 cc: ERROR File = ../../../include/ao/ao_private.h, Line = 183 An unmatched left parentheses "(" appears in an expression. #define awarn(format, args...) {\ ^ cc-1018 cc: ERROR File = ../../../include/ao/ao_private.h, Line = 197 An unmatched left parentheses "(" appears in an expression. #define aerror(format, args...) { \ ^ cc-1029 cc: ERROR File = ao_irix.c, Line = 123 An expression is expected at this point. aerror("alSetQueueSize failed: %s\n", ^ cc-1055 cc: ERROR File = ao_irix.c, Line = 130 A macro invocation has too many arguments. device->output_channels, alGetErrorString(oserror())); ^ cc-1029 cc: ERROR File = ao_irix.c, Line = 129 An expression is expected at this point. aerror("alSetChannels(%d) failed: %s\n", ^ cc-1029 cc: ERROR File = ao_irix.c, Line = 137 An expression is expected at this point. aerror("alSetDevice failed: %s\n", ^ cc-1029 cc: ERROR File = ao_irix.c, Line = 143 An expression is expected at this point. aerror("alSetSampFmt failed: %s\n", ^ cc-1029 cc: ERROR File = ao_irix.c, Line = 165 An expression is expected at this point. aerror("unsupported bit with %d\n", ^ cc-1029 cc: ERROR File = ao_irix.c, Line = 171 An expression is expected at this point. aerror("alSetWidth failed: %s\n", ^ cc-1029 cc: ERROR File = ao_irix.c, Line = 180 An expression is expected at this point. aerror("alOpenPort failed: %s\n", ^ cc-1029 cc: ERROR File = ao_irix.c, Line = 189 An expression is expected at this point. aerror("alSetParams() failed: %s\n", alGetErrorString(oserror())); ^ 14 errors detected in the compilation of "ao_irix.c". ... which happens because MIPSpro supports variadic macros of the form 'f(x,...)' but not with named arguments such as 'f(x,y...)'. Correcting the macros definitions and the implementations to use __VA_ARGS__ results in a further problem that some invocations of the macros include only a single argument and some multiple arguments, resulting in: cc-1054 cc: ERROR File = audio_out.c, Line = 217 There are not enough arguments in a macro invocation. adebug("Testing drivers to find playback default...\n"); ... etc.
Created attachment 230455 [details, diff] libao-1.0.0-irix.patch Patch to fix variadic macros for IRIX/MIPSpro. Not pretty, but it works ;)
Created attachment 230465 [details, diff] libao-1.0.0-c99.patch Okay - ignore that last patch: it still contained GNU-isms (oops) and made (too many) changes outside of the affected header. Here is a new version which makes a cosmetic change to the output (all debug messages will be prefixed by their debug level, whereas previously logging "\n" alone produced only a blank line on &2) but has the benefit of actually conforming to C99 (without GNU extensions), and so should be applicable on all platforms.
We are sorry to close this bug. We lack the man-power and devotion to support mips-irix in the tree.
