Describe the bug A clear and concise description of what the bug is.

To Reproduce Steps to reproduce the behavior:

Expected behavior A clear and concise description of what you expected to happen.

Environment:

• OS name: [e.g. linux] run uname -s
• OS version: [e.g. CentOS 7.6]
• OS architecture: [e.g. x86_64] run uname -m
• Bear version: [e.g. 3.15.0]
• Bear install method: [e.g. from package]

Additional context

• Can you give us a reference to the project that you are running against this tool? [e.g. No if it's a close source project, but in case of an open source project a link to the sources could be nice.]
• What build tools this project is using? [e.g. GNU make wtih configure script]
• What architecture you are trying to compile for? [e.g. cross compiling]
• Could you attach build logs? If you can re-run the command which failed (e.g. bear -- make) with extra verbose log switches (e.g. bear --verbose -- make) and send the output of it, that would help a lot.

Before you send...

• Have you read the README.md file or man bear?
• Have you looked what other open issues Bear has?
• Are you sure that the build works without Bear?

1.get bear source and compile. cmake ../Bear-2.4.3/ -DCMAKE_C_COMPILER_ARG1="-m32"; VERBOSE=1 make all; cmake ../Bear-2.4.3/ -DCMAKE_C_COMPILER_ARG1="-m64"; VERBOSE=1 make all;

2.compile ok and check the libear.so. (dir 64-- 64bit , dir 32--32bit) xxxx@ubuntu:~/workspace/tools/64/libear$ file libear.so libear.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=60bcee5e81fab27ba1e7c08abad2cf8550a54d4f, not stripped

Hey @zxx1234 ,

The multilib issue is documented on the wiki. You probably want to have a look at it. And I would also recommend to read man ld.so page, "Dynamic string token" section.

But since the multilib is not tested in CI, it might be broken. Sorry for that!
