include path problems

[tuli]

hi,

[edit: This is a general problem i have with a lot of libraries, i'm using LLVM as an illustrative example.]

I want to use the LLVM framework libraries.
So i downloaded LLVM, compiled it, added the include\ and \build\lib\ directories to my default paths and gave it a go.

however, i keep getting problems like this:

error C1083: Cannot open include file: 'llvm/Support/DataTypes.h': No such file or directory c:\users\tuli\desktop\lllvm\llvm\include\llvm-c\core.h 18

this is the code in question (core.h)

#include "llvm/Support/DataTypes.h"

Ofcourse: if you use "x.h" instead of <x.h>, it wont find the llvm/ dir, which i added previously to the include paths!



my code:

#include <llvm-c/Analysis.h>
#include <llvm-c/Disassembler.h>


int main()
{
	return 0;
}

I have had this issue before with other libraries. Previously, i'd just change all the #include "..." to #include <...>.
There are way too many header files involved here, though.


What to do?


spec:
VS2010 sp1
Win 7 sp 1 x64
latest llvm

If the header is not found when you use this:

#include "xyz"

The preprocessor should re-try as if it were:

#include <xyz>

Hence, a manual change should be unnecessary.

I wonder if this is just a case of you adding wrong paths to the list of paths to be searched for headers.

Resolved! Thanks!


The fault lies with some sort of cmake hiccup. DataTypes.h was located in the wrong directory, and i found a DataTypes.h.cmake in its place. Rearranging the files appropriately solved the problem.
(Previously, i just checked for the existence of "DataTypes.*"...)

It's still a little wired that i was able to resolve very similar errors by ""/<> substitution. Maybe i'll get back to that after the holydays.
