How to determine which command line options gcc passes to ld by default?

Question

Consider the hello world C program:

hello.c:

#include \"stdio.h\"

int main()
{
        printf(\"Hello, World!\\n\");
}

Answer 1

For oneline lovers:

echo "int main(void) {}" | gcc -o /dev/null -v -x c - &> /dev/stdout| grep collect | tr -s " " "\012"

Replace -x c with -x c++ to get c++ flags.

Can be used also with clang, but in such case you should grep for /usr/bin/ld
