If a variable is declared as extern non-array in one module
and then defined as an array in another, a linker error may occur:
Definition: foo.c:uint64_t variable[SIZE];
Reference: bar.c:extern uint64_t variable; ld: The value 0xXXX does not fit when applying the relocation GPREL22 for
symbol "variable" at offset 0xYYY in section index ZZZ of file bar.o. |
Workaround: The declaration should be changed to: extern uint64_t variable[];
This error can also occur in assembly code if items <=
8 bytes are put into .data/.bss instead of .sdata/.sbss.
Workaround (assembler): For "small" variables defined in assembly,
change the section name from .bss to .sbss or .data to .sdata:
.section .sdata = "asw", "progbits" .align 8gggggggg:: data4 0x000003e7 |
