I failed to build Qt
-
I want to build Qt for my windows machine but it doesn't work.
I entered from a directory called Qt-5.8.0-build "..\Qt-5.8.0-src\configure.bat -debug-and-release -platform win32-g++ -prefix C:\Qt\Qt-5.8.0- bin-x64
But I got some errors:
C:/Qt/Qt-5.8.0-src/qtbase/tools/configure/environment.cpp: In static member function 'static Compiler Environment::detectCompiler()': C:/Qt/Qt-5.8.0-src/qtbase/tools/configure/environment.cpp:144:50: error: 'KEY_WOW64_32KEY' was not declared in this scope KEY_WOW64_32KEY).toLower(); ^ C:/Qt/Qt-5.8.0-src/qtbase/tools/configure/environment.cpp: In static member function 'static QString Environment::execute(const QString&, int*)': C:/Qt/Qt-5.8.0-src/qtbase/tools/configure/environment.cpp:389:60: error: '_popen' was not declared in this scope FILE *proc = _popen(command.toLatin1().constData(), "r"); ^ C:/Qt/Qt-5.8.0-src/qtbase/tools/configure/environment.cpp:399:29: error: '_pclose' was not declared in this scope int r = _pclose(proc); ^ <builtin>: recipe for target 'environment.o' failed mingw32-make: *** [environment.o] Error 1What could I do to make it work?
Thanks for help

Hi,
Which compiler are you using exactly ?
-
32 or 64 bit ?

I installed mingw-w64 and now I have the 6.3.0 version. It works now but there are a lot of other problems:
At the end of configure it checks the gold linker and then a window appears with the text: ld.gold.exe doesn't work anymore. My options are "Debug" and "Close program". When I use the second it continues with checking things. Then I type mingw32-make -j4 and then: it compiles but suddenly there are a lot of problems. The entry point "_ZdaPvy" was not found in the DLL ...\rcc.exe. It appears more than one time. After this there are ptoblems like "waiting for unfinished jobs" and then compiling was aborted

@Gravak said in I failed to build Qt:

I had the same problem and found no solution online, so in case someone else has the same issue:
This error can occur if you have another, incompatible version of libstdc++-6.dll in your PATH. Make sure that the right one is found first, e.g. that it's location appears soon enough in the PATH environment variable.

This issue occurs if you open the command line (visual studio) and try to compile Qt. Please try to open cmd from an old Qt ex 5.9.1 and try from it to compile, this should use the mingw32-make from 5.9.1 for example, otherwise you should correct the path.
