Hi Afif,
BWA failed to build on i386 at version 0.7.5a-1 with the following error,
despite the -D_NO_SSE2 option:
/usr/lib/gcc/i486-linux-gnu/4.7/include/emmintrin.h:32:3: error: #error "SSE2 instruction set not enabled"
https://buildd.debian.org/status/fetch.php?pkg=bwa&arch=i386&ver=0.7.5a-1&stamp=1370353173
I expect that if you try to build it on i386, it will fail again.
In any case, for most bioinformatics software that is now developed on amd64, I
would not trust output of the programs built successfully on other
architectures unless there are good regression tests.
So I take the opportunity to say a big thank you to the people working on
regression tests right now :)
Have a nice day,
