Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Cannot Build C++ Project with 4.10.2


After installing 4.10.2 and VS 2015 (several times), I am in the situation that I cannot build a simple blank C++ project. When I build in VS, I get the following output.

I'm totally stumped and could not find any info on this specific error (could not get full path for tool -q), so your help is much appreciated.

Hello KyotoG,

What build configuration is your Visual Studio project attempting to build in? Did you use any previous versions of the engine/VS prior to this where you didn't have these issues? Are you using a Binary build (downloaded from the Launcher) or a source built engine? If you're using a Binary build, as a possible general fix, can you try verifying the installation through the launcher to see if it helps at all?

I tried several configs, which all gave the same error: Development, Development Editor, Game Debug, Shipping. The above error is from the Development config.

I installed 4.10 first (but only tried blueprint projects, which worked fine both on 4.10 and 4.10.2). A few days later, 4.10.2 was released so I installed that.

I'm using the Binary build, so I'll take you advice and try verifying and will post my results soon.

I reinstalled, and unfortunately get the same issue as before. This is the output when generating the project from the New Projects tab of the project browser.

The project could not be compiled. Would you like to open it in Visual Studio?

I went ahead and tried to build the Unreal Engine myself (from GitHub) and I get the same error. "could not get full path for tool -q" What is the build looking for? Is there a way of getting a more verbose output so I can try and track down what the actual issue is?

I found this thread, which points to SN-DBS being the problem. I'll first try upgrading, and if that fails, uninstalling it.

I couldn't upgrade SN-DBS as this would affect everyone in our company, but uninstalling solved the issue.
