• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

i've been trying to build a project that was originally coded for 32 bit... while trying to get the code running when i selected the 64bit SimConnect.lib into the VC++ directories and Additional Include directories i got these errors while trying to build.

You need to update the platform you are using to compile the project. You should be using VS2015 or later. or get the updates.

from the wiki on MS VS C++

MSVC++ 4.x _MSC_VER == 1000 (Visual Studio 4.0?)
MSVC++ 5.0 _MSC_VER == 1100 (Visual Studio 97)
MSVC++ 6.0 _MSC_VER == 1200 (Visual Studio 6.0)
MSVC++ 7.0 _MSC_VER == 1300 (Visual Studio .NET 2002)
MSVC++ 7.1 _MSC_VER == 1310 (Visual Studio .NET 2003)
MSVC++ 8.0 _MSC_VER == 1400 (Visual Studio 2005)
MSVC++ 9.0 _MSC_VER == 1500 (Visual Studio 2008)
MSVC++ 10.0 _MSC_VER == 1600 (Visual Studio 2010)
MSVC++ 11.0 _MSC_VER == 1700 (Visual Studio 2012)
MSVC++ 12.0 _MSC_VER == 1800 (Visual Studio 2013)
MSVC++ 14.0 _MSC_VER == 1900 (Visual Studio 2015)
MSVC++ 14.1 _MSC_VER >= 1910 (Visual Studio 2017)
 
i am running visual studio 2017... i will look into the update thanks!


EDIT: doing that changing the project target SDK to 10.0.16299.0 instead of NO UPGRADE gave me 312 errors...

Recall that .lib files created with VS are version specific. Whether you use VS2015 or VS2017, you need to use the VS2015 toolset.
Also, SimConnect.lib is compiled with the /MD option, so your project should also be compiled with /MD.

How would i compile with /MD sir?

EDIT: I have set the runtime library property to /MD

now that i have fixed most of those errors i have been having errors that have to do with "abs"

for example most of the abs errors have to do with the float zoom... :
Code: 
float zoom = abs(ppage->zoom);
Code: 
int w = 0, h = 0;
    page_s* ppage = current_page();
    if (ppage!=NULL) 
    {
        w = (int)(ppage->mediawidth * abs(ppage->zoom));
        h = (int)(ppage->mediaheight* abs(ppage->zoom));
 
In the first example, i presume that ppage->zoom is a double, rather than a float, so that VS doesn't understand whether you want to convert the double to a float and then return the absolute value, or whether you want to return the absolute value as a double and then convert that value to a float.
Explicitly casting ppage->zoom should probably solve the problem.
float zoom = abs( (float)(ppage->zoom) );

changing :
float zoom = abs(ppage->zoom);
to :
float zoom = abs( (float)(ppage->zoom) );
did not work ... errors still are there...

i should also add that ppage is the current page (displaying pdf in sim ) the project was orriginally coded on VS2010 and only compatible upto p3d v3.. i really want to recompile and fix the errors to get it for p3d v4 ...

I tripped over this one recently when upgrading a project from VS2013 to VS2015. The maths libraries have changed. Somewhere in your project you will have a line that says:

#include <maths.h>

Change it to

#include <cmath>

and that should shut up the abs errors. Note: cmath is correct. There is no .h suffix.
 
I was able to resolve most of the errors... now i am stuck with these:

these are my last errors i need to solve... ive been working really hard to resolve all other 300 + errors...
 
Normally caused by declaring a callback function and then not implementing it e.g. if I declared

ICON_UPDATE_CALLBACK switch_icon_cb;

and then had no

FLOAT64 FSAPI switch_icon_cb( PELEMENT_ICON pelement)

body I'd expect to see a similar error. As you've got so many errors of the same type, I'd be checking to see if an #include directive is missing.
