READ THE BAZEL INTRODUCTIONS PART TWO POST FIRST!
Note that this is what worked for me on Debian Jessie. It probably won’t work for you.
Write the file
#include <iostream>
int main() {
std::cout << "Hello, World\n";
return 0;
}
Run the preprocessor on the file
$ cpp main.cpp -o main.i
This will take the cpp file, run the preprocessor, and then output the .i file.
Convert the .i file to assembly code
$ g++ -S -o main.s main.i
gcc with the -S option only converts the preprocessed file into assembly. It outputs it to main.s.
Convert the .s file to an object file.
$ /usr/bin/as main.s -o main.o
Link the .o file into an executable
$ ld \
> -dynamic-linker \
> /lib64/ld-linux-x86-64.so.2 \
> -o main \
> /usr/lib/gcc/x86_64-linux-gnu/4.9/../../../x86_64-linux-gnu/crt1.o \
> /usr/lib/gcc/x86_64-linux-gnu/4.9/../../../x86_64-linux-gnu/crti.o \
> /usr/lib/gcc/x86_64-linux-gnu/4.9/crtbegin.o \
> main.o \
> -L/usr/lib/gcc/x86_64-linux-gnu/4.9 \
> -lstdc++ \
> -lc \
> /usr/lib/gcc/x86_64-linux-gnu/4.9/crtend.o \
> /usr/lib/gcc/x86_64-linux-gnu/4.9/../../../x86_64-linux-gnu/crtn.o
This ld command will be completely different on a different computer/version of g++. I created it by using g++ -v and copying the command line options for the linker which I actually needed. The above should be totally minimal.
Run the executable!
$ ./main
Hello, World
In the words of rubenvb on StackOverflow, “It’s not practical to do this… ever.”
I’d like to thank StackOverflow, manpages, caffeine, and the sheer grit available at 2:00 AM for my completion of this project.
was it worth it? No.
