Are static c libraries created with one compiler compatible with another?

In my case I have a library built with code sourcery gcc targeting arm cortex-m4. I am trying to then link that library into a project being compiled with IAR compiler.

Is it possible to do this or does the library have to be rebuilt with the new tools? What factors affect this?

Solution

  • Static library is bundle of several object files which are always compiler specific. So if you try to link a gcc based lib with IAR compiler, you will get error at compile time due to mismatch between object file formats to be linked.

    You need to rebuild your library using IAR.
