Thanks, I had run JNI successful :)
1st,there are mistake of library name, I use
System.loadLibrary("libNativeAdd");to load library,
2st, lack of libgcc.a while linking,
“ - when you create an executable (either static or dynamic) *or* a
shared library, link it to this libgcc.a. this means that the
aeabi
functions required by the executable/library are directly copied
into it.
yes, this also means that these functions will be duplicated in the
process
space of a program that links to several shared libraries requiring
them.
note that libgcc.a must appear last in your link command. ”
If I build shared library without "libgcc.a" but instead of "-static",
why it cann't duplicated aeabi functions to my library?
