>> Analysis of Gregor's pkgsrc failure results
>> Gregor Richards has run the whole NetBSD pkgsrc build (over 10k
packages) against musl and posted reports to the mailing list and wiki.
Some analysis on the most frequent causes of failure could be extremely
helpful to improving compatibility. It would also be nice to identify
major dependency failures that can be fixed (either in the upstream
package if it's buggy, or in musl if it's due to missing features) so
that the packages which depend on them can be tested too. I'm looking
to get results in the form of "we should fix X and Y and Z and then
lots more packages will work".
> ISTR that Gregor has something that gives him scores for how important
different packages are.
This is mvd.txt in the results tarball. (see musl.codu.org)
Higher scores (at the top) mean more valuable/more packages stopped here.
And looking at what it says, I see these scores:
Ruby193-base: 904
pari: 674
qt3-libs: 394
qt4-libs: 358
....
libf2c: 282
....
g95: 152
....
SDL: 135
