Thank you.
it seems I misunderstand the meaning of "archive" in the document. :P
So I change the script as below:
OUTPUT_ARCH(mips)
SECTIONS
{
.onlyText 0x80000000 : { lib2.a:*.o (*.text) }
}
OUTPUT_ARCH(mips)
SECTIONS
{
.onlyText 0x80000000 : { lib2.a: (*.text) }
}
and link command as:
mipsel-linux-gnu-ld -Bstatic -T ./link.xn -o TEST_LINK.elf -Map
TEST_LINK.map --oformat elf32-tradlittlemips lib2.a
but I still cannot see the section I named in the script file shows up
in final elf.
