Have you compiled some parts with a different version of a compiler? I had problems when I compiled caffe with 4.x since I believe it uses some components that are installed by default in Ubuntu 15.10 (which are compiled with 5.x), but in some cases these aren't compatible (some String-thing was changed between the versions).

I tried gcc-5.2、gcc-4.7、gcc-4.8，but the String problems still remained

If you changed compilers after one compilation failed, I think the new compilation uses some elements from the previous compilation.

I don't remember the exact error message I got but I remember it looked very similar to yours. I fixed it by starting from scratch (reinstalled linux.. luckily I didn't have any personal settings to keep) and compiling everything with the default Ubuntu 15.10 compiler. If you can't find other solutions to your problem, you could try the same thing on a clean install on a VM
