最佳答案
我已经解决了这个问题。
方法:
当我编译 cups-filter 时，我在标志中指定参数“-Wl,--rpath=lib_path_in_run_board”:CFLAGS、CXXFLAGS、CPPFLAGS。为什么需要指定三个标志？我必须确保将 lib_path_in_run_board 编译到执行程序中。
还有一个问题让我很困惑。 liblcms2.so.2 存在于 LD_LIBRARY_PATH 环境中的搜索目录中。我使用 LD_DEBUG=libs execute_program 进行调试可以看到它会搜索 LD_LIBRARY_PATH 中的目录并找到指定的库。为什么实际执行会报“error while loading shared libraries: liblcms2.so.2: cannot open shared object file: No such file or directory”。我真的不明白。
