Header correct, but compile error(identifier not found)

I am trying to include vdb in a project (github.com/mmp/pbrt-v2)

I had try vdb's examples, every example works fine.

but in this project(pbrt), I ran into Error identifier not found

here is my code:

#include "../vdb.h"
#include "stdafx.h"
#include "shapes/heightfieldImproved.h"
#include "shapes/trianglemesh.h"
#include "paramset.h"

// heightfieldImproved Method Definitions
HeightfieldImproved::HeightfieldImproved(const Transform *o2w, const Transform *w2o, bool ro, int x, int y, const float *zs)
    : Shape(o2w, w2o, ro) {
    nx = x;
    ny = y;
    z = new float[nx*ny];
    memcpy(z, zs, nx*ny*sizeof(float));

    nVoxels[0] = nx - 1;
    nVoxels[1] = ny - 1;
    nVoxels[2] = 1;

    ComputeVertexNormal();
    vdb_line(0, 0, 0, 1, 1, 1);
}

IntelliSense works fine, it knew what vdb_line() is, but when I built whole project, the error raised("vdb_line": identifier not found)

I'm using visual studio 2015 on win10

Thanks!

I change the include as full path

#include "C:\Users\ssarcandy\Documents\GitHub\pbrt-v2\src\vdb.h"

and still get the same error....
there just only one error:

"vdb_line": identifier not found

--- edited2 --- After I change the order of include, as follow:

#include "stdafx.h"
#include "C:\Users\ssarcandy\Documents\GitHub\pbrt-v2\src\vdb.h"

I get lots of errors:

The proper place to include vdb.h is after stdafx.h, not before. By default if your project is set to use precompiled headers, it will ignore all includes that come before stdafx.h in a source file. You should have seen a warning telling you this before that error that you mentioned in your post:

warning C4627: '#include "vdb.h"': skipped when looking for precompiled header use
note: Add directive to 'StdAfx.h' or rebuild precompiled header

This is way it later failed the compilation telling you it can't find that function.

Now if you move the include statement after stdafx.h you get a lot of errors, most of them about duplicate definitions of WinSock related names. That's because you end up including both winsock.h and WinSock2.h. The first one gets included from windows.h which in turn gets included on a long chain starting with stdafx.h and ending in parallel.h. The second one gets included directly from vdb.h.

To fix this you can go about in two ways:

1. Make windows.h not include winsock.h automatically

To do this, you define the macro WIN32_LEAN_AND_MEAN at the top of stdafx.h, before any other include statements.

#define WIN32_LEAN_AND_MEAN

This disables the inclusion of a few more headers besides winsock.h, so you might get some new errors when you do it. You could try to fix these by including the appropriate headers directly where needed.

I'm not familiar with the PBRT project and it's source code, I don't know if it actually uses WinSock or it just got the header included without it realizing, so I can't tell you exactly what new problems you might run into.

2. Convert vdb to using winsock instead of winsock2

I'm not familiar with this project either so I can't tell you how much work this would involve. But on a first look it looks doable if for some reason the first method fails.

The compiler does not know what vdb_line is. The line

#include "../vdb.h"

is probably not correct since the header file, according to your github link, does have the cdb_line deklaration. Try including vdb.h with the explicit path to verify. Place the header file correctly relative your working directory to include it with "../vdb.h".

Intellisense has it owns mechanics. By default, it only uses standard include directories to find header files. But other files, even non project files, can be added for intellisense to parse. It is not strange that intellisense knows the cdb_line declaraion and the compiler does not but as to why, we would have to look into your visual studio project settings.
