Hi all

During chromium compilation on Linux (Debian testing, 64bit, gcc 4.7.1, cmake 2.8.9), the python script action_makenames.py fails with the following error:

...

Failed to install: chromium

It looks like the python script is called a perl script, and the perl script is dying on line 209:

die "Unknown parameter $parameter for tags/attrs\n" if !defined($parameters{$parameter});

The 'unknown parameter's are:
1. math
2. a
3. a interfaceName
4. actuate
5. xmlns

I'm not sure where these parameters are coming from.

Anyone have any idea how to correct this?

Cheers

Jarrett

Turns out to be a preprocessor bug for gcc 4.6. As a fix, you have to remove the -P parameter of the gcc preprocessor command in make_names.pl.
