[alsa-devel] Cross compile issues with alsa-utils

15 Jan 2009

Hi All,
I have been cross compiling alsa-utils with buildroot (www.buildroot.org) and have run 
into two issues.
The first is that alsactl is using index & rindex which are legacy functions not supported 
with all cross compile toolchains. Attached is a patch to replace the calls with strchr 
and strrchr.
The second issue is again with alsactl. It is trying to generate the alsactl_init.7 man 
page but I do not have xmlto to convert it to a man page. Could a configure option be 
added to not build any docs - similar to alsa-lib configure.
Thanks,
Will.
