Hi all,
I have a platformIO project, I’m trying to understand how pio links binaries with mbed.
If I put a lot of C++ classes in the project (headers in include and implementations in src), but I don’t use them, so my main.c is the following:
#inlcude "mbed.h"
int main() {
while(1);
return 0;
}
I get a .elf file of 13992 bytes.
If I move the classes outside the project (f.e. in a directory tmp outside src and include) and I use the same main file, I obtain a .elf file of 9444 bytes.
Why the linker is linking symbols that I am not using? Is there a way to avoid it?
