BWA compilation error

[mabry]

I'm trying to complie BWA on my Linux (Fedora 9, x86_64) box from bwa-0.6.4 source. But, when I type 'make',

make[1]: Entering directory `/usr/local/bwa-0.4.6'
make[1]: Nothing to be done for `lib'.
make[1]: Leaving directory `/usr/local/bwa-0.4.6'

Any suggestions would be appreciated.
Thanks.

add this line to the beginning of bwtaln.c:

#include <unistd.h>

Hi lh3,

I could successfully compile bwa with the modifications of the additional two files, bwape.c and bwase.c, in same way.
Thank you so much for your help.
