problem compiling SVN (r26382)

[turin]

For the last week or so, I've had problems compiling the latest SVN checkout. The errors have been getting progressively worse. Most recently, on trying to run

Code: Select all

scons wesnoth wesnoth_editor prefix=/home/turin prefsdir=.wesnoth

I got this:

Code: Select all

scons: Reading SConscript files ...
Saved options: prefix = '/home/turin'
Checking whether C++ compiler works (g++ version >= 3.3 required)... (cached) no
Base prerequisites are not met.

Which is, of course, absurd. I have g++ 3.4 and 4.1. And I've never had any problems compiling Wesnoth before. So does anyone have any idea what is going on? Is the command I'm using to compile (the "scons" line above) incorrect somehow? Or is SVN broken at the moment?

Try using the "--config=force all" parameter. I had the same issue before updating to scons 0.98.3 btw.

OK, yeah, that does it.

Could you explain to me exactly what that's doing to allow me to compile, though? I don't really like the idea of "forcing" the computer to do something I don't understand.

It forces config checks to be rerun. Due to bug in scons 0.97 caching of config checks was broken. It's fixed in 0.98 and I've removed TargetSignatures() call that was triggering it so it shouldn't occur in 0.97 anymore too.
