Hi, Recently I want to use gcc to learning the compiler. And I know the program `gcc` is a collection of preprocessed, compiler, assembler, linker and other tools. So I try to use `gcc -E`,`gcc -S`,`gcc -c` and `gcc -o` to preprocess, compile, assemble and link to build a program successfully. But when I try to use `cpp`, `cpp -S`, `as` and `ld` to build a program, the output of program is wrong. The source code of program is "helloword" in C. The command is: $ cpp ../main.c -o main.i $ gcc -S main.i $ as main.s -o main.o $ ld main.o -o main -I/lib64/ld-linux-x86-64.so.2 -lc -e main The output of program is: $ ./main Hello World! Segmentation fault (core dumped) I think reason is `ld`. Because when I use `gcc -o` replace `as`, the program will work fine. So I want to know how to set `ld` option can make it work same as `gcc -o`. Looking forward to your reply, Thanks.
