--- Comment #10 from xiehongbiao <xiehongbiao at sensetime dot com> --- (In reply to Andrew Pinski from comment #8) > Can you also add -Wl,-v ; this will cause collect2 to print it runs? It reports error :"gcc: error: unrecognized command line option ‘-Wl’". Please let me know if I misunderstood. Thanks. Paste the details: jiaojiancheng@jiaojiancheng:~/test_compile$ gcc -O1 -pedantic -fomit-frame-pointer -m64 -Wl -v conftest.c Using built-in specs.
