I don’t use Projucer much, only when I add new files.

I think my previous version was 7.0.2.

After upgrading I now get the following error for my synth, which compiled without errors and worked fine before (this morning). I’m using Visual Studio 2022 64-bit current version;

Working my way back through the releases, using “Rebuild Solution”;

7.06 - Same issue  
7.05 - Seemingly built ok, but when trying to run, lots of errors.  
7.04 - As 7.05  
7.03 - As 7.04, see below;  
7.02 - Even with “Rebuild Solution” I get same “VST3\_SDK” / Steinberg errors as in build 7.03! I needed to code this afternoon. Is there a version I can download that has not changed causing the errors below?

Can’t get past the “VST3\_SDK” errors even trying release 6.1.6 and 6.0.

Can anyone please tell me what release contains the previous (older), but in my project working “VST3\_SDK” files?

Fortunately for me I was able to copy my working JUCE folder from a spare Laptop, which I last used in May 2023.

The version I actually had was 7.0.5, and it “Rebuild Solution” complies without errors. So I assume something happened in version 7.0.6 or 7.07 that caused the VST3\_SDK file errors.

Be _sure_ you are on the appropriate branch, if you’re using git … the **develop** branch can often be a bit thorny.

When switching JUCE versions, it’s vital that you resave the project using a copy of the Projucer that matches the JUCE version.

In practice, this means that after updating to a new version of JUCE, you must rebuild the Projucer using the project files included with the updated copy of JUCE, and then use that Projucer to resave your project.

I think its good practice to create a script, which automatically rebuilds projucer and resaves all \*.jucer projects within your repository automatically via projucer with “–resave” option.

Ok Saving the project I will do, but what exactly do you mean by “rebuild the Projucer”? I do not see a rebuild option in Projucer.

In `extras/Projucer/Builds` you can find project files to build the Projucer itself.

++ seems, same. Problems with VST after upgrade from 7.05 to 7.07 and 7.08  
Most strange, is that the one .jucer file is generating project , which have errors during compilation, but another .jucer file with slightly different options (plugin name / manufacturer code, etc) , with the same source folder as above, make project which compiling fine.

I am using git, but don’t have a “clear” commit before and after migrate from 7.05 to 7.08.

I have never thought of that. I have always just used the Projucer.exe provided in the JUCE folder as part of the release download. Maybe the rebuilding instructions only really applies if I’m using GitHub instead of the all-inclusive downloads.

Hm, I found this in my .juce file  
\<JUCERPROJECT …  
headerPath=“…/…/asio/common\*\* \*\*”\>  
but it was not the problem, but problem was a local copy of “processor”. Don’t know how it became ‘local’

Hi I am using CMake with the following package declaration

```auto
include(cmake/cpm.cmake)

CPMAddPackage(
    NAME JUCE
    GIT_TAG 7.0.5
    VERSION 7.0.5
    GITHUB_REPOSITORY juce-framework/JUCE
    SOURCE_DIR ${LIB_DIR}/juce
)

```

7.0.5 works as it should but I get warnings and cannot compile VST3 when I remove my build folder and lib/juce folder, and

```auto
cmake -S . -B build
cmake --build build

```

defining a higher JUCE version e.g. 7.0.6 … 7.0.9 🙂

Is it possible to upgrade this way ? 🙂  
Best, Lasse
