When writing and debugging functions, it is easier for the C compiler (either GCC or G++) to link the program as the C compiler is aware of the appropriate locations for the various C/C++ libraries.
For example, assuming that the source file is named example.asm, the commands to compile, assemble, link, and execute as follows:
yasm -g dwarf2 -f elf64 example.asm -l example.lst
gcc -g -o example example.o
Note, Ubuntu 18 will require the no-pie option on the gcc command as shown:
gcc -g -no-pie -o example example.o
This will use the GCC compiler to call the linker, reading the example.o object file and creating the example executable file. The “-g” option includes the debugging information in the executable file in the usual manner. The file names can be changed as desired.
