New subject: [linux-audio-user] Re: csound5.05.0 wont compile with alsa1.0.14rc3

26 Mar 2007

Hi Dragan,

I just downloaded alsa-lib-devel 1.0.14rc1 which came in from yum
upgrade and I got the same issue as you.  For a fix, in
csound/InOut/rtalsa.c, I added this just before the #include of
csdl.h:

#ifndef _POSIX_C_SOURCE
#define _POSIX_C_SOURCE 1
#endif

which got it to compile. As I'm not familiar with the above macro,
I'll be asking the csound developer's list in a moment if this is the
correct solution, but this should work for you to get around compiling
now.

  hi list,
 i am just about trying to compile csound5.05.0 in order to use csLADSPA,
 but as long i try to run scons with 'useALSA=1' i get following error:

 i tried looking at sourceforge but no success, so perhaps someone here
 is familiar with the issue.
 i already tried to compile the v5.04 and the cvs too, but always the
 same error.

 i would appreciate  any help.

 cheers,
 doc
