How to create an alias for a build target with a relative path in Scons?

Question

Background

I tried Scons by creating a basic C ++ project that has two subprojects:

• Prj1 is an exe that depends on Prj2
• Prj2 is a DLL that exports some functions.

You can see the directory structure and contents of my SConstruct and SConscript files here

Problem

The problem I am facing is that in order to create these goals from the command line, I must specify both the relative path to their build directory and their extensions for specific platforms.

For example, to create Prj1 I need to do:

build> scons ../bin/project1.exe

Similarly, to create Prj2 I need to do:

build> scons ../bin/project2.dll

Question

How can I get SCons to create these projects without specifying a relative path extension and platform extension?

Desired:

build> scons project1 
build> scons project2

Alias ​​ . , , "project1" ( PROG) . . PrefixProgram :

def PrefixProgram(env, outdir, trgt, srcs):
    return env.Program(target = os.path.join(outdir, trgt), source = srcs)

:

target = PrefixProgram( prj1_env, BIN_DIR, PROG, SOURCES )
prj1_env.Alias("project1", target)

, , :

prj1_env.Alias("project1", PrefixProgram( prj1_env, BIN_DIR, PROG, SOURCES ))
