SConstruct file
I'm trying to build this project https://github.com/TTimo/es_core, and don't have enought expirience with scons
Based on the SConstruct file referenced in your question, you're not correctly linking in the boost_system library. You're doing it as follows:
env.Append( CCFLAGS = [ '-g', '-lboost_system', ] )
The CCFLAGS variable should be used to pass compilation flags to the Compiler. The -l flag should be passed to the Linker, not the Compiler. The correct way to do that in SCons is as follows:
env.Append( LIBS = ['boost_system'] )
Notice, I dont add the -l flag, as SCons does that for you in a platform-independent manner.
You may also have to define the path to the library, which is done as follows:
env.Append( LIBPATH = '/put/the/path/here' )
As with the LIBS, you dont need to add the -L flag to LIBPATH, as SCons will add it.
Here is a complete list of the SCons Construction Variables.
