[Scons-users] Define function in SConsctruct, use in SConscript

[Elliott Wolin]

Hi,

Just started with scons, simple question, I tried various things and 
nothing worked.  Also, I know little about Python (to the credit of both 
I was able to develop a moderately sophisticated build system anyway!).

Problem is, I create a function in SConscript:

def modify_environment(env,reqlist) :
         # process dependency lists
         list = reqlist.split()
         for l in list:
                 exec("from load" + l + " import load" +l)
                 exec("load" + l + "(env)")
         Export('modify_environment')

but cannot figure out how to use it in SConscript.  I tried various 
Import() statments, none worked.  Typical error:

$ scons -c
scons: Reading SConscript files ...
NameError: name 'modify_environment' is not defined:

I tried exporting modify_environment in the SConscript() call, but it 
complained it is not a variable.


$ scons -version
