Hello, I am working on a bare metal C++ ELF project targeting Zynq CPU1 (the 2nd CPU). I successfully tested a simple Xilinx standalone application, and then started removing dependence on the standalone BSP, like this:
* I removed the BSP include and library paths from the project.
* I rewrote the startup.s and asm_vectors.s to not depend on any code from BSP.
But g++ linker is apparently still pulling in libc, as you can see below. I will NOT use any libc functions. Is there a way to tell g++ not to link against libc at all? Thank you for your help!
