Help with fg-from-scratch

Postby pb321 » Fri Nov 01, 2019 4:02 pm

Trying to compile with fg-from-scratch and get the following in the first few lines of scratch.log:
Code: Select all
White Text Fix: 0
scratch-source/openscenegraph-3.6-git
scratch-build/openscenegraph-3.6
'qtpaths.exe' is not recognized as an internal or external command,
operable program or batch file.
QT Folder:
CMake Toolchain: "Visual Studio 15 2017 Win64"
Updating vcpkg . . .
Already up to date.
Compiling vcpkg
The property 'instance' cannot be found on this object. Verify that the
property exists.


QT 5.10.1 is installed in c:\qt, as I understand it should be. In addition, I'm using cmake-3.13.3-win64-x64, Git for Windows v2.20.1 and Visual Studio 2017.

Any suggestions will be very much appreciated!

@pb321,

Sorry for my delayed reply. Just getting back to FG after taking a break for a few months.
qtpaths.exe is a program that installs with Qt - fg-from-scratch uses this to understand how to link with your install.

Before running fg-from-scratch, ensure your PATH includes the Qt\bin folder containing the program qtpaths.exe
Code: Select all
set PATH=C:\Qt\5.13.1\msvc2017_64\bin;%PATH%

I compiled a fgfs.exe with fg-from-scratch successfully in C:\fg
I modified the PATH environment variable to include:
C:\Qt and C:\fg\scratch-install\bin

I get The code execution cannot proceed because gdal204.dll was not found. Reinstalling the program may fix this problem. Same message for OpenAL32.dll and libcurl.dll


a second run of fg-from-scratch seems to have fixed these errors and fgfs starts.

But now I'm getting:
Reqired data files not found, please check your installation. Looking for base-package files at '../data/

What should ../data be?

I downloaded a zip of fgdata and placed it in c:\data

Now fgfs starts, I get a white window and it immediately closes.

command window has: the following and then nothing happens.
