Hello everyone,  
I have just updated JUCE to 5.3.1 version and all of a sudden I got a lot of problems building my project. 72 to be exact. I have never experienced something like that and I have tried for hours to make it work but I had zero success. During compiling ,Visual studio 15 which I use, gets to this first:

```
e:\audioplug-ins\framework\juce\modules\juce_gui_basics\layout/juce_Grid.cpp(317): error 
C2059: syntax error: '}' (compiling source file 
..\..\JuceLibraryCode\include_juce_gui_basics.cpp)
1>e:\audioplug-ins\framework\juce\modules\juce_gui_basics\layout/juce_Grid.cpp(941): fatal 
error C1903: unable to recover from previous error(s); stopping compilation (compiling source 
file ..\..\JuceLibraryCode\include_juce_gui_basics.cpp)
1> INTERNAL COMPILER ERROR in 'E:\Program Files (x86)\Microsoft Visual Studio 
14.0\VC\bin\x86_amd64\CL.exe'
1> Please choose the Technical Support command on the Visual C++
1> Help menu, or open the Technical Support help file for more information
1>cl : Command line error D8040: error creating or communicating with child process

```

After that it starts to build my vst and here all hell breaks loose 😕

```

What happened here? If you need more details about my project settings and debugging I will gladly share.

Thanks in advance,

Looks like the same issue as [this post](https://forum.juce.com/t/juce-v5-3-0-error-after-update/26905). Can you try the steps listed in there?

I have just tried that now without success. Instead of all errors from before, now I only have:

| Severity | Code | Description | Project | File | Line |
| --- | --- | --- | --- | --- | --- |
| Error | LNK1104 | cannot open file ‘DrPad.lib’ | DrPad\_VST | E:\AudioPlug-ins\DrPad\Builds\VisualStudio2015\LINK | 1 |

And the wierd syntax error from juce\_gui\_basics is still there.

Have you cleaned the project in Visual Studio and rebuilt?

Yes, I have done Clean solution ,and then rebuild solution. I have tried any combination with these 3,clean build rebuild options ☹

Are you trying to link to a 3rd party lib?

As for the syntax error in gui\_basics, it’s a compiler error that seems to only occur in VS2015 where it expects braces around a `jassert`. I’ve pushed a fix that should be on develop shortly but you just need to add some braces at line 315 of `juce_Grid.cpp` like so:

```auto
if (strings.size() > 0)
{
    for (auto s : strings)
    {
        jassert (s.size() == strings[0].size()); // all rows must have the same number of columns
    }
}

```

Those magic braces sorted everything out. Now it works, thanks for helping, it was driving me crazy, I appreciate it. Cheers !

Great. The fix will be on develop in a moment once it passes our CI builds so you can pull it in instead of locally patching your JUCE.
