[Scons-users] Problems with SCons parallel build

[Brady Johnson]

Gary,

Ya, I was just about to reply saying that the thrift file is used for code
gen, but its not generated, it exists when the build starts.

Dirk,

I just checked and there are builders that do "cd" via the Command()
builder. I'll look at them to see if what they are doing (its something
like this: "cd /some/dir ; jar xvf /some/file") can be done without the
"cd", but if not is there a way around this?  Its been a long week, and my
brain is fried right now, so I probably wont get back until tomorrow.

Thanks for the info guys!! :)

Regards,

Brady
