Are you sure this works? On my system it is an enum, not a define.

You are absolutely right, it doesn't. I was a victim of my own "add error
inside #ifdef/else and recompile test", probably recompiled before saving.

Would you mind helping me understand why the check at [1] fails with:

14734 configure:13848: checking for MPG123_IGNORE_INFOFRAME
14735 configure:13848: ccache gcc-4.6 -m32 -c -g -O0   conftest.c >&5
14736 configure:13848: $? = 0
14737 configure:13848: ccache gcc-4.6 -m32 -c -g -O0   conftest.c >&5
14738 configure:13848: $? = 0
14739 configure:13848: result: no

[1] http://pastebin.com/nveZQNDR

I never did this sort of change before and the best example I found
was some libxml2 stuff inside configure.ac.

Thanks in advance,
Bruno

Usually config.log also contains the code which was used for the check.
In this case, I would assume it fails because MPG123_IGNORE_INFOFRAME
isn't really a type. The type is "enum mpg123_param_flags", but testing
for that obviously doesn't make much sense.

I would suggest a slightly different solution. The commit where the
feature (including the MPG123_IGNORE_INFOFRAME const) was added is:

https://www.mpg123.de/cgi-bin/scm/mpg123?view=revision&revision=2910
https://www.mpg123.de/cgi-bin/scm/mpg123/trunk/src/libmpg123/mpg123.h.in?r1=...

As you can see, in the same commit the API_VERSION was bumped to 31.

https://www.mpg123.de/cgi-bin/scm/mpg123/trunk/configure.ac?r1=2910&r2=2...

So why not just something like:

#if MPG123_API_VERSION >= 31 /* needed for MPG123_IGNORE_FRAMEINFO */

Best regards,
Sebastian

Usually there is the code, but not in this case. I don't know why.

Looks perfect to me, thanks =)

I just checked, and Ubuntu Precise ships header files with:
"#define MPG123_API_VERSION 25"
So such a solution would indeed fix the issue. Alternatively you could
of course also define the missing enum for API_VERSION < 31.
