Vim Syntastic显示警告并设置警告级别

Question

I use Vim with syntastic to code in C++ and I see all errors but I don't get any warnings. It would be nice if I didn't have to use the compiler in the terminal just to get all compiler-messages. Some errors differ in different c++ standards so it should be possible to at least change the version of c++ to error-check for.

• How do I do I show warnings?
• How do I set the warning levels and settings as I do when I compile a program using g++?
• How do I set this up if I start using another language? If I get a specific command to run for c++, then I would be lost the next time.

I can't find how to do this from the manual at :h syntastic . I have only looked at the sections that I thought were relevant however.

Answer 1

for every project, in .vimrc in the project folder i will put something like

let g:syntastic_cpp_compiler_options="-m32 -I ./inc -I ./inc/libs"

you can select -w , -Wno- or any warning level you want

use g:syntastic_c_compiler_options for pure C code

ofcourse you put this in the global .vimrc. here we use vim to edit code in several programming languages, so we use different .vimrc per project
