SetSubDirPlatform is definitely the wrong rule in this case. It sets the
platform for which the targets in this Jamfile are being built. In practice the
only real application is for build tools to mark them as to be built for the
host platform, though the BuildPlatform{Main,SharedLibrary,...} rules do that
implicitly just for the target in question and are therefore generally
preferrable. So SetSubDirPlatform exists basically for sake of completeness.
In case you mean the SetSubDirSupportedPlatforms rule, it really does exactly
what its name tells you: It sets the supported platforms for the subdirectory
to the ones you pass to it. If you only pass "libbe_test", then the targets can
only be built for "libbe_test". There's an AddSubDirSupportedPlatforms rule,
which also does exactly what one would expect from its name and which is
probably the one you'd want to use in this case.
Regarding a possibly different handling of shared and static libraries, the
SharedLibrary and StaticLibrary rules use exactly the same statement for
checking the supported platform:
if ! [ IsPlatformSupportedForTarget $(1) ] {
return ;
}
So at least from the code I wouldn't see how they could behave differently in
this respect. If you have a concrete case, please feed it to the bug tracker.
CU, Ingo
