Difference between -shared and -Wl,-shared of the GCC options

Question

I know -Wl,-shared is a option of ld. I\'ve seen some person compile like this,

$ gcc -shared -Wl,-soname,libtest.so -o libtest         


        

Answer 1

I don't think there is any difference. -shared is not a supported option of gcc and it is passed to linker whether you specify it with -Wl or not. -Wl option of gcc is used to specify that a comma separated list of options is to be passed to linker for further processing.
