Solved Problem building qt static on win 10
-
I am trying to build a static version of qt on win 10 and get the following error:
C:\Qt\5.12.2\Src\qtbase\src\corelib\global\qlibraryinfo.cpp: fatal error C1853: 'qmake_pch.pch' precompiled header file is from a previous version of the compiler, or the precompiled header is C++ and you are using it from C (or vice versa)
This is surprising since I configured to not use precompiled headers. Here is how I am building the system if this gives any clues, or any of my configure options may be wrong
"\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvars64.bat"
configure -static -release -no-pch -platform win32-msvc2017 -confirm-license -prefix "\QtStatic" -opensource -mp -nomake examples -nomake tests -no-icu -no-opengl -no-angle -no-openssl -skip webengine
Any help would be welcome....

Did you use a clean source and build directory or did you compile with other options before in there?

It was clean at the beginning, although I have fiddled around with having or not having -no-pch since then. I will nuke the C:\Qt\5.12.2\Src directory and try again, but this will take a few hours. -

OK. My mistake. I deleted the sources using the maintenance tool, deleted what was left in the Src directory, downloaded, and executed the two commands - and it built perfectly. So I must have done something wrong along the way. I see now the the qmake_pch.pch is build in the configure stage not the nmake stage, so it must have been me who built it with the wrong compiler.Apologies for wasting your time. I should have had the sense to rebuild from scratch without needing to be prompted.
