Unknown CMake command "QT4_WRAP_CPP".

[rnordstrom]

Hello!
This has been tried on both a WinXP (64 bit) and a Win7 (32 bit) system. IDE is Visual Studio 2010.
Running the file "Make VS10 Project Files.bat", renders the error "Unknown CMake command "QT4_WRAP_CPP".", both from the current revision (4761) or at the latest release version (4230).
Following the advice given in other threads, and linking to an own installation of QT4 (v.4.8.6) works initially, but renders the error "QtCore4.dll cannot be found" when running a built test module, as per this thread. The wiki also advices against this build method, citing "DLL hell" issues.

To quote mellingers post

There is no USE_STD_QT any more -- instead, cmake will try to detect whether there is a BCI2000-precompiled version of Qt available for your platform/compiler, and will try to detect an external installation of Qt if this is not the case.

I cannot get this method to work. I have tested it on both XP and 7, CMake v.2.8.3 (linked from here) and latest stable release (3.0.2, downloaded from Cmake.org). Output below;

Is there another way to get the "stripped-down, precompiled version of Qt" refered to on the wiki?

Problem solved by adding C:\Qt\4.8.6\bin to PATH. Now I can build against an external QT lib, and run the executables.

I seem to be having the same problem. I was wondering if you could add more details on how you fixed it. Did you add C:\QT\4.8.6\bin to PATH of CMAKE or PATH of VS2010?

Thanks!

I meet this problem, too. Plz let me know if there is any solution.

Thx!

Hi,
sorry for not replying earlier.
The BCI2000 trunk is currently broken and will remain so until the next binary release comes out, which is scheduled for the first quarter of this year.

If you experience build problems, please check out the source code version corresponding to the most recent binary release, as suggested on the BCI2000 wiki:

http://www.bci2000.org/svn/stable

instead of /svn/trunk.

Regards,
Juergen

Hello!

Very sorry for late answer. I added the search path to QT:s bin-directory ("C:\QT\4.8.6\bin", but it might be different on your system) in Windows PATH variable. To set it, one can navigate via Windows GUI:

• Click the Windows-orb/Start-button
• Right-click Computer->Properties
• "Advanced System Settings" (left side)
• "Environment Variables"-button
• Edit the variable named "Path". Use a semicolon (;) to separate two entries, remember to enclose path in double quotes (") if it has spaces.
