so with help of someone from BugReport portal, the solution was extremly simple...
as you can see form the log:
eea6d5ef-d2db-4406-8d50-50e2ca9c185a-image.png
C and C++ compler is pucked up from PERL, not form MinGW,
so I have onlymoved MinGW environment variables PATH above the PERL and then all worked fine...

they also suggested to try specify:

-DCMAKE_CXX_COMPILER=C:/path/to/mingw/compiler/g++.exe -DCMAKE_C_COMPILER=C:/path/to/mingw/compiler/gcc.exe

but im not sure where to put this realy.

other option (im only thinking, was not suggested) is to use MingwDir parameter in configure

but not sure if the Qt is this smart enough to use this parameter as a compiler path for C and C++, this has to be tested realy

First try to for the use of OpenGL.

Otherwise, you will have to build Qt itself.

@surajj4837 Hey, can you please provide your solution to this issue? Thank you ...

@TBRZ said in Fix for build error "member access into incomplete type 'const clang::FileEntry'":

notify the developers about a problem

This is user forum. If you want to communicate with developers you should either use bug tracker or the mailing list.

@Davronito Yes many times.........

Hi,

Two question:

Why Qt 5.7.1 ? The current LTS is 5.12.5 Can you use a more recent version of GCC ? 4.4 is a bit old.

@Linuxfluesterer No it's not the size of your hard drive, it's the size of the RAM allocated to that machine and how much it uses for /tmp.

So do a df -h and you can post the output or at least see how much space you have on tmp. If it is less than the 1.4gb needed for the install, up it. Or as I suggested temporarily point /tmp to a hard disk if you don't have the ram for a bigger /tmp.

I made several modifications ... but i think the properly modifications are

In : QtSrc\qtbase\mkspecs\win32-g++\qmake.conf add

QMAKE_LFLAGS += -static -static-libgcc QMAKE_CFLAGS_RELEASE -= -O2 QMAKE_CFLAGS_RELEASE += -Os -momit-leaf-frame-pointer DEFINES += QT_STATIC_BUILD

In : QtSrc\qtbase\src\plugins\sqldrivers\oci\oci.pro add

QMAKE_LFLAGS += oracle_home\oci\lib\msvc\oci.lib QMAKE_LFLAGS += oracle_home\oci\lib\msvc\ociw32.lib QMAKE_LFLAGS += oracle_home\oci\lib\msvc\oraocci11.lib LIBS += -Loracle_home\oci\lib\msvc -loci -lociw32 -loraocci11 INCLUDEPATH += oracle_home\oci\include

cmd

-static -debug-and-release -platform win32-g++ -prefix QtPath\Static -I C:\\OpenSSL-Win32\\include -L C:\\OpenSSL-Win32\\lib -opensource -confirm-license -c++std c++14 -nomake examples -skip qtdoc -skip wayland -skip purchasing -skip serialbus -skip qtserialport -skip script -skip scxml -skip speech -skip location -no-opengl -no-angle -qt-zlib -qt-pcre -qt-libpng -no-libjpeg -qt-freetype -sql-oci -I oracle_home\oci\include -L oracle_home\oci\lib\msvc

try it. the other modifications do not matter

@no_ideaw Can you show your pro file?
Also did you run qmake and rebuild your project after changing Kit to "Android for armeabi-v7a"?

Old post but I had the same error; I had to build qtdeclarative BEFORE qwebchannel to solve this error.

Hi,

What version of Qt are you trying to build ? Which options did you pass to configure ? What was the configuration summary ?
