Building Qt5 source code fails 'No suitable compiler found in PATH. Aborting.'

Dongha Kang

Hi,

I need older version of Qt5 (5.6.0) and I keep getting the same error. This is my step (I am trying to be super specific so here I go).

I use Windows 10
I have MSVC2015 (I need this version..). So all of these, I worked in Developer Command Prompt for VS2015
clone qt repository ... fetched it, perl init-repository worked perfectly in git bash...
When I run ..\qt5\configure -developer-build -opensource -nomake tests -nomake example I get the error saying

C:\Users\DELL\Desktop\qt5-build>..\qt5\configure
+ cd qtbase
+ C:\Users\DELL\Desktop\qt5\qtbase\configure.bat -top-level
Please wait while bootstrapping configure ...
<srcbase> = C:/Users/DELL/Desktop/qt5/qtbase
<outbase> = C:/Users/DELL/Desktop/qt5-build/qtbase
No suitable compiler found in PATH. Aborting.

Here is my PATH

>> echo %PATH%
C:\Perl64\bin;C:\Users\DELL\AppData\Roaming\ActiveState\bin;C:\Program Files\dotnet\;C:\Users\DELL\.dnx\bin;C:\Program Files\Microsoft DNX\Dnvm;C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin;C:\Users\DELL\AppData\Local\Programs\Python\Python39\Scripts\;C:\Users\DELL\AppData\Local\Programs\Python\Python39;C:\Users\DELL\AppData\Local\atom\bin;C:\Users\DELL\.dotnet\tools;C:\Program Files (x86)\Windows Kits\10\bin;C:\Program Files\Git\bin;C:\Program Files\Git\cmd;C:\Windows\System32\WindowsPowerShell\v1.0;C:\Program Files\CMake\bin;

C:\Program Files\Git\bin;C:\Program Files\Git\cmd;
C:\Windows\System32\WindowsPowerShell\v1.0;
C:\Program Files\CMake\bin;

I have been struggling for a while.. If someone can help me with this. That will be fantastic ;(

Hi,

Did you checkout the corresponding branch ?

In any case, you should rather start from the archive.

You can then follow the build instructions from the documentation.

In any case, even if locked to the 5.6 series, I would recommend to use the latest minor release available for it rather than the .0 release.

Running into the same issue.

The Microsoft C++ compiler (cl.exe IIRC) is in none of the directories in the OP's system path. It seems the OP did use the VS2015 developer command prompt, which does expose the compiler if present. I think that at some point Microsoft decided that C/C++ compilers would not be installed by default with Visual Studio, so that is possibly the cause. If you have a full VS then it should be an option you can add.

If are not blessed with VS then this is another way to get the compilers:
