Unfortunately, I can’t get to the bottom of this at the moment.
I tried installing devkit from master on a XP VM following your
instructions, but mingw’s make segfaults. I don’t know what’s causing
it. And the machine I used to test on has been wiped, so this VM is all
I’ve got to test on right now :frowning:

If you’re seeing something like below, it could be that something on the
XP system is conflicting with the DevKit’s msys-1.0.dll and the DLL
needs to be rebased [1]. We’ve recently seen an issue [2] in which an
AV vendor’s DLL collided with the DevKit’s msys-1.0.dll. The fix was a
“rebase -b 0x30000000 msys-1.0.dll” If you want to double check, the
VMMap GUI tool [3] makes it pretty simple.

HTH.

I’m on vacation for a week and will look again when I return. FYI,
looks like build.xml’s new clean-tzdata [4] target causes problems when
using msysgit’s portable version. Doesn’t look to be a showstopper and
I’ll try to get you a patch when I return. You’d think “osfamily” on
the and a windows-only would solve it, but one of the 3
ways to run msysgit portable (git-bash.bat) causes problems.
