Using gcc plugins with cross compiler, undefined symbol

QUESTION

Using gcc plugins with cross compiler, undefined symbol

Asked 2020-Feb-05 at 17:37

I'm trying to see if it's possible to use a gcc plugin in an ARM cross compiler (arm-none-eabi-gcc). I'm running into compiler errors however, and am questioning whether what I'm trying to do is possible.

The plugin I'm trying to set up is: https://github.com/vanhauser-thc/AFLplusplus/tree/master/gcc_plugin

I'm compiling the plugin on x86-64 linux using the -m32 flag, since the cross compiler is a 32-bit application. However when I try to use the plugin in the cross compiler using -fplugin , I get an undefined symbol compiler error:

cc1plus: error: cannot load plugin ../afl-gcc-pass.so ../afl-gcc-pass.so: undefined symbol: _Z13build_int_cstP9tree_nodel

I looked through the plugin's symbols using nm and discovered that the majority of symbols are undefined, including ones like exit and random. I'm new to most of this and am unsure of what that really means. Some searching online suggested that it may have had something to do with incorrect library paths, but setting LIBRARY_PATH and LD_LIBRARY_PATH and rebuilding did not seem to help.

The gcc version set-ups I have tried:

1: x86: 5.4.0 , arm: 5.4.1 on ubuntu 16.04

2: x86: 5.2.0 , arm: 5.2.1 on CentOS 6.8

Is it possible to use a gcc plugin in a different gcc than it was compiled with or am I wasting my time?

Yes, it is possible to build a gcc plugin with a given compiler and then use the plugin in another compiler (including a cross-compiler), but you have to make sure you include the right header files when building the plugin. Specifically, you have to include the plugin development header files of the target compiler, instead of those of the host compiler. The directory where plugin development files for your target compiler are located can be obtained with the following command:
