"g++ --verbose" - GCC Compiler Steps and Settings
This section provides a tutorial example on how to dump GCC compiler steps and settings using the 'g++ --verbose' command option.
If you are running into issues with the GCC C++ compiler, you may want to use the "g++ --verbose" to dump all current settings from the compiler.
herong$ g++ --verbose hello.cpp ... Target: x86_64-redhat-linux Configured with: ../configure --enable-bootstrap --enable-languages=c,c++,fortran,lto ... /usr/libexec/gcc/x86_64-redhat-linux/8/cc1plus -quiet -v -D_GNU_SOURCE hello.cpp -quiet -dumpbase hello.cpp -mtune=generic -march=x86-64 -auxbase hello -version -o /tmp/cceaNqFM.s ignoring nonexistent directory "/usr/lib/gcc/x86_64-redhat-linux/8/include-fixed" ignoring nonexistent directory "/usr/x86_64-redhat-linux/include" #include "..." search starts here: #include <...> search starts here: /usr/include/c++/8 /usr/include/c++/8/x86_64-redhat-linux /usr/include/c++/8/backward /usr/lib/gcc/x86_64-redhat-linux/8/include /usr/local/include /usr/include End of search list. as -v --64 -o /tmp/ccGgvc09.o /tmp/cceaNqFM.s COMPILER_PATH=/usr/libexec/gcc/x86_64-redhat-linux/8/: ...

So the "g++" command actually runs 3 commands: cc1plus, as, collect2.
