从QPrintSupport上的源错误编译Qt 5.3.1

Question

I'm not sure whether or not this question has a causality with my previous question .

So, I compiled Qt 5.3.1 from source with MinGW 4.8.2. The build stopped at qtbase/src/printsupport directory, as you can see the image below:

Is it a bug or something at qtbase/src/printsupport/kernel/qprintengine_win.cpp file? Then, should I just report it to the developer?

Answer 1

Look here it give you a hint. Probably somewhere you use this key -Werror in make files implicitly or explicitly when start compilation with gcc. If I correct understand error in that switch operation must be default: statement or case PPK_CustomBase: statement.

Answer 2

miraiE,

If you will notice in your output: cc1plus.exe: all warnings being treated as errors This is, as was mentioned before, a warning that is stopping the compile process as an error.

You should be able to run you configure.bat script again, with the option -no-warnings-are-errors. Then re-run your make.exe to get past this, and other warnings, from stopping the build.

Details of the specific configure options below:

../qtbase-opensource-src-5.3.1/configure --help |grep -i warn

-silent ............ Reduce the build output so that warnings and errors

-no-warnings-are-errors Make warnings be treated normally

-warnings-are-errors Make warnings be treated as errors

I hope this helps!
