Question

我尝试制作jni共享库。

我在这个库的代码中使用了boost库。

我成功地在开发机器上创建了共享库并完成了测试。

我创建了lib lib文件夹，其中包含libboost _ *。所以文件在目标机器上，并将其添加到LD_LIBRARY_PATH。

所以，我尝试在目标机器上测试（与开发机器相同的OS平台），但目标机器无法链接它。

所以，我的java程序找到我的.so（libsample.so）但是libsample.so找不到boost库并抛出消息（未定义的符号：_ZTIN5boost6detail16thread_data_baseE）

我该如何解决这个问题？

我想在我的共享库中打包提升库
或者我想使用我的共享库自动与boost库进行链接。

谢谢，Martin Bonner。

我解决了这个问题。

这是我编辑的CMakeLists.txt

在此cmake运行之前，我使用-cxxflags = -fPIC重新编译boost库，因为this issue

我成功地将.so库包括boost库作为静态库。

C ++如何将boost库与我的共享库链接起来在目标机器上工作？
