[Scons-users] AppendUnique doesn't append unique

[Rob Deckers]

Hi,

We encountered in our Scons build environment that the build randomly failed, especially the unittests.

A further investigation showed VERY big (to big) command lines because of the link dependencies.
First we slimmed down the link dependancies list, but also we saw doubles in the list, even though we used 

[code]
# Add additional library paths to LIBPATH variable so the linker can find the libs
env.AppendUnique(
  LIBPATH = [add_libpath]
)
[/code]

We replaced this with:
[code]
# Add additional library paths to LIBPATH variable so the linker can find the libs, and skip duplicates
if not 'LIBPATH' in env:
  env['LIBPATH'] = []
for dir in add_libpath:
  if dir not in env['LIBPATH']:
    env['LIBPATH'].append(dir)
[/code]

And this works.

Have others also encountered a not working env.AppendUnique ?
I didn't find anything like it with googling.

Kind Regards,
Rob Deckers
