Unable to build static version of Qt 5.15.2

@Christian-Ehrlicher Yep. I figured as much after I asked. So that is done and it seemed to get further in the compilation but I'm still getting errors:

As you can see the compiler complains again about numeric_limits so add this include there too.

[robertwilliamallen]

@Christian-Ehrlicher Added #include <limits> to qbytearraymatcher.h and it worked. Thanks for your help! Just getting into Qt and definitely feeling the learning curve.

@robertwilliamallen It works,good job!!!

I am using Qt5.12.6 and I was getting the same error. While attempting this solution I noticed that qglobal.h is included in all these files mentioned, so I added limits include to the __cplusplus check like this and it worked:

#ifdef __cplusplus
#  include <type_traits>
#  include <limits>
#  include <cstddef>
#  include <utility>
#endif

@Christian-Ehrlicher Hello,
is there anywhere we can ask for the files to be updated? the ones in the https://download.qt.io/official_releases/qt/5.15/5.15.2/single/
still have this issue I struggled to compile it until I found this post by chance.... would be great to rectify this for other future people out there....

@otaolafr Hi,

If you are building from source anyway, you should download a more recent version such as 5.15.11. See the content of the 5.15 releases folder.

it generates this error with gcc11.x

compile it specifically using gcc9.x (for e.g. gcc9.4) and it will compile without any problem
