Boost filesystem error on Android

I am trying to integrate oF0.9.0 and I get this error:

fatal error: boost/filesystem.hpp: No such file or directory

In the beginning of libs/openFrameworks/utils/ofFileUtils.h, there are these lines:

#include <boost/filesystem.hpp>
    namespace std {
    namespace filesystem = boost::filesystem;
}

And in the libs/openFrameworksCompiled/project/android/config.android.default.mk, there is this exclusion:

PLATFORM_CORE_EXCLUSIONS += $(OF_LIBS_PATH)/boost/include/boost/%

Is this implementation ok? Or is this the reason of the error I get?

no, that’s correct, it excludes everything in include/boost but not include/boost itself, so #include "boost/filesystem.hpp" should work.

Hi Arturo, so do you have an idea about what might be the reason of the error?

Oh

nm -gC libOFAndroidApp.so

gives

nm: libOFAndroidApp.so: no symbols

I think I made a mistake in the compilation.
