I'd like to compile cpp file w/o turning off vi.
I know the :!g++ file.cpp but I prefer :make so I added this line in .vimrc file
au FileType C set makeprg=gcc\ %
au FileType Cpp set makeprg=g++\ %
but I keep getting
"make: ***** No targets specified and no makefile found. Stop.** "message.
can anyone tell me what is wrong with my setting?
I use to compile successfully with the option above.
I should change C,Cpp into c,cpp, then it works fine.
thank you all, especially Rob Wells, your answer helped me a lot. thank you.
You need the substitution there, try something like:
set makeprg=gmake\ %:r.o
Oh, this assumes that you've got:
Check for the default by entering:
make -n <my_file>.o
and see if that gives you something sensible.
If there is a makefile in another location you can add the -f option to point at the makefile, for example:
set makeprg=gmake\ -f\ ../some_other_dir/makefile\ %:r.o
BTW For learning about make, and especially gmake, I'd suggest having a look at the excellent book "Managing Projects with GNU Make" (sanitised Amazon link).
