Assuming you set the directory that your library is built into in your env['LIBPATH'] list, then you should just be able to specify the library(ies) in the LIBS in your program statement.

Hmm. I was just looking at the documents and we don't have a good example in them.


so if you build your library into libdir then in your bin1 dir's SConscript
env.Program('bin',['bin1.c'],LIBDIR=['../libdir'],LIBS=['lib1'])
