我正在编译我自己的链接到 libjpeg 的库。我在两台计算机上进行了编译，但这在其中一台计算机上不起作用。错误如下：
Wrong JPEG library version: library is 62, caller expects 80
但是只安装了 libjpeg8：
/usr/lib/i386-linux-gnu/libjpeg.so.8
/usr/lib/i386-linux-gnu/libjpeg.so.8.0.2
/usr/lib/x86_64-linux-gnu/libjpeg.a
/usr/lib/x86_64-linux-gnu/libjpeg.so
/usr/lib/x86_64-linux-gnu/libjpeg.so.8
/usr/lib/x86_64-linux-gnu/libjpeg.so.8.0.2
/usr/local/cuda-5.0/jre/lib/amd64/libjpeg.so
我的 cmake 链接到正确的 SO 文件：
-- Found libjpeg:
-- - Includes: /usr/include
-- - Libraries: /usr/lib/x86_64-linux-gnu/libjpeg.so
老实说，我不知道发生了什么……有什么想法吗？提前致谢 ！
有一些奇怪的东西。如果我没有将我的程序链接到任何类型的 jpeg 库，我的代码就会编译，并且我可以执行它并且我也会收到相同的消息错误。但是，如果我对我的可执行文件执行 ldd，则没有 libjpeg 的痕迹。这怎么可能？
