Comment(by AlexanderDreyer):
There are two kind of environment variables.
First, there are {{{PATH}}}, {{{LD_LIBRARY_PATH}}}, {{{CPATH}}} (used by
gcc} and similar ones. Those just have to be imported to the build
environment, for instance by the following patch to !PolyBoRi's
{{{SConstruct}}} file:
{{{
#!diff -u
@@ -377,17 +377,12 @@
tools += ["disttar", "doxygen"]
-# Get paths an related things from current environment
-# note: we cannot avoid those due to non-standard system setups
-getenv = dict()
-for key in ['PATH', 'HOME', 'LD_LIBRARY_PATH'] :
- try:
- getenv[key] = os.environ[key]
- except KeyError:
- pass
+# Get paths and related things from current environment os.environ
+# note: We cannot avoid those due to non-standard system setups,
+# also we do not know which variables are used in general
-
-env = Environment(ENV = getenv, options = opts, tools = tools, toolpath =
'.')
+env = Environment(ENV = os.environ, options = opts, tools = tools,
+ toolpath = '.')
env['RPATH'] = env.Literal('\\$$ORIGIN/')
}}}
On the other hand, there are variables like {{{CFLAGS}}}, {{{LDFLAGS}}}...
Those are not used by the compiler directly, but by {{{make}}}-based build
systems. So we have to tell {{{scons}}} what we intended with them. For
instance, we have to add a line like the following to the configuration
file {{{custom.py}}} in the spkg:
{{{
#!python
CXXFLAGS=os.environ['CXXFLAGS']
}}}
