Hi Guy,

Sorry to take a while to respond, just got back from vacation.

I think even if you could get past the u_char problem (which would be pretty simple to do), the next problem may be there is no OSS or ALSA sound libraries available for cygwin.  If neither OSS or ALSA is available for cygwin then you are not going to get anywhere.  I would check that out before going any farther...

Good luck, and let us know what you find out.

Subject: [Gwc-general] Fwd: Help with compile on cygwin 1.7


I'm hoping you can help me out. I LOVE your application. I used it extensively to record some old holiday albums which I made as a Christmas gift to my siblings. Now I want to use it again. Unfortunately, in the interim, my laptop has, for various reasons, been reverted to its original Windows OS and thus I no longer have an Ubuntu install I can use your program in.

So, I've looked at the two options I have, run it in a VM (Sun VirtualBox) and run it under cygwin. The VM route won't work at all. I was able to install it, but the data files are >1 Gb and just loading one takes 15 minutes, then, unfortunately, gwc crashes. Not enough RAM, etc. is my thinking.

I turned to cygwin. Things were looking pretty good, actually. I have the devel packages installed and configure runs to completion without error. Make starts and all is looking fine until it gets to audio_util.c. Then all hell breaks loose :-) Unfortunately I'm no C programmer and even with make in debug mode there is little I can make sense of.  Make is successful on these files:


Here's the make output on
audio_util.c at this point:

I checked fmtheaders.h and the lines that gcc is hollering about seem to be:

# ifndef MAC_OS_X
# ifndef __u_char_defined
typedef __u_char u_char;
typedef __u_short u_short;
typedef __u_int u_int;
typedef __u_long u_long;
typedef __quad_t quad_t;
typedef __u_quad_t u_quad_t;
typedef __fsid_t fsid_t;
#  define __u_char_defined
# endif
# endif /* MAC_OS_X*/

And that's it. I would not have thought the warnings would lead to catastrophic failure (other c files also produce such warnings yet compile successfully). I've tried running just gcc on audio_utils.c with the right syntax and -o audio_utils.o for output and gcc reports the same warnings, no errors and no abort, but also no object file output.

I know this is still a long way from done done -- but it's a start. I wish I had the programming chops to figure this out (just reading through the c code makes me glad that I only need to do the occasional shell/Perl script :-), but I don't so I have to turn to you. I did check the cygports project and they don't make your excellent tool as part of it.
