dlopen, link error

[yosemite]

Hi,

My C code #include <dlfcn.h> and calls a dlopen. But when I built it,
there is a link error saying "undefined reference to `dlopen' ". Do I
need to add some link option for the libdl?

Thanks,

Yes, add the following:

LOCAL_LDLIBS := $(SYSROOT)/usr/lib -lld

Thanks Dave. But I got the following error:

"build/platforms/android-1.5/arch-arm/usr/lib: file not recognized: Is a directory

collect2: ld returned 1 exit status"

By the way, my $(SYSROOT) does not contain any libld.so/a but libdl.so. However, even after I change OCAL_LDLIBS to $(SYSROOT)/usr/lib -ldl, the error still exists. Any clue?

[David Turner]

sorry, my typo:

LOCAL_LDLIBS += -L$(SYSROOT)/usr/lib -ldl

Note that there is a small bug in this release of the NDK, the -L$(SYSROOT)/usr/lib part will not be needed in future ones.
