Problem building clang on Windows 7

[eranif]

You need to add the include paths for clang ( the gcc default ones )

For example, for me, I had to add the following line into:

Settings -> Build Settings -> Compilers -> clang++ -> Advanced -> Include Paths

Code: Select all

c:\mingw-4.7.1\lib\gcc\mingw32\4.7.1\include\c++;c:\mingw-4.7.1\lib\gcc\mingw32\4.7.1\include\c++\mingw32;c:\mingw-4.7.1\lib\gcc\mingw32\4.7.1\include\c++\backward;c:\mingw-4.7.1\lib\gcc\mingw32\4.7.1\include;c:\mingw-4.7.1\include;c:\mingw-4.7.1\lib\gcc\mingw32\4.7.1\include-fixed

and it worked. Remember that you also need to disable EH (Exception Handling) using -fno-exceptions flag

Damn, this is like having your teeth pulled by Hannibal Lecter...
well did a little research and found this which led me here for a canonical source, at the bottom of the page, wow. And so:

• Code: Select all

  End of search list.

The -v switch is terribly verbose and gives the search path(s) of which I have none. I think I can handle this...

That's where the @#% it was?!!! I thought I would lose it when I couldn't find where you'd update the include path. Danke sehr, Eran!
