how to make bear work with different compilers

[jpy139]

I'm trying to setup a development environment for a company project.
After installing bear, I found it works with the gcc I installed via apt, but when used together with the cross compiler that I installed manually, I always got the following error:

ERROR: ld.so: object '/usr/local/$LIB/bear/libexec.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

I thought it might be because the cross compiler is 32bit and the one that works fine is 64bit, but this problem still exist after I installed both 32bit and 64bit bear accroding to wiki. I also checked the previously reported issues but didn't get a working solution. So I wonder if you have time to help analyze.

Environment:

OS name: Linux

OS version: Ubuntu 22.04.2 LTS

OS architecture: x86_64

Bear version: 3.1.2

Bear install method: built from source

What architecture you are trying to compile for? arm 32bit

cross compiler：arm-none-eabi-gcc

@jpy139, your set up looks good. The multilib setup is not tested by CI, and it might be broken. Sorry for that.

@rizsotto Hello, and thank you for your reply,
Currently I just want to get Bear+arm-none-eabi-gcc working, can you let me know how should I fix it next?
