JNI, error when using two .so files where one needs the other

Question

I have two .so files - A.so and B.so, where A.so needs B.so.

I use System.setProperty("java.library.path","thePath");

and I check System.out.println(System.getProperty("java.library.path"));

Then I load A.so using System.load("/absolutePath/A.so");

A.so and B.so are in the same directory.

The error I get is that B.so can not find.

I can not use LD_LIBRARY_PATH.

ldd A.so shows B.so => ./B.so

I also use System.loadLibrary("A"); but the error is that A can not find.

Answer 1

The only solution may be:

Let ldd shows the absolute path.

Edit the CMakeList.txt file:

LINK_DIRECTORIES("/the/absolute/path/")

target_link_libraries(A B.so)

UPDATE:

Find the way, I only give the whole cmake file example.

cmake_minimum_required(VERSION 3.12)
project(xgbtSimiCalcer)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x -fpermissive -m64 -Wl,--no-as-needed -O3 -march=native")

SET(xgbtSimiCalcer_SRC test0.cpp ../test1.cpp)

INCLUDE_DIRECTORIES(./)
INCLUDE_DIRECTORIES(../)

SET(CMAKE_INSTALL_RPATH "\\$ORIGIN")
LINK_DIRECTORIES("${CMAKE_SOURCE_DIR}/../../model/")
LINK_LIBRARIES("${CMAKE_SOURCE_DIR}/../../test.so")
ADD_LIBRARY(xgbtSimiCalcer SHARED ${xgbtSimiCalcer_SRC})
TARGET_LINK_LIBRARIES(xgbtSimiCalcer m.so dl.so pthread.so)
SET(LIBRARY_OUTPUT_PATH "../../tmp")
SET(INSTALL_DIR "${CMAKE_SOURCE_DIR}/../../model_")
INSTALL(TARGETS xgbtSimiCalcer LIBRARY DESTINATION ${INSTALL_DIR})
