[Scons-users] scons 'Install' builder could not recognize file changed

[Ronex Dicapriyo]

This needs me to call install target and then use main target, But I want it to get resolve in the invocation of main target as the included file found to be updated(it's MD5 signature should be changed).

I think you are missing something here.  Create your install targets first.  If you setup your dependencies correctly, calling "scons install" on a clean working directly will build all out-of-date targets and install them.

Please read the documentation for install because it doesn't appear that you have.

V/R,
William

    Install builder works as expected. 
I wasn't aware about COMMAND_LINE_TARGETS variable. However even if I tried to use it, It produceses same behavior:

Because you're using the VariantDir option with duplicate=0, SCons includes the variant dirs as well as the source folders. The actual library file could exist in either one of them, or both.Is there any way to avoid this, using the VariantDir in a way I have used, rather then using it in SConscript funcion call ?
