Configure Qt5

[GrahamL]

Hi
I downloaded Qt5 and ran the following configure command
configure -platform win32-g++
This gave me the following error

cc1plus.exe: error: unrecognized command line option "-fno-keep-inline-dllexport"
mingw32-make: *** [tmp/obj/debug_shared/arch.o] Error 1

What can I do to fix this?

Thanks

Graham

You need a GCC version >= 4.6 to build Qt5.

You can find a recent version "here":http://sourceforge.net/projects/mingwbuilds/.

Hi
Thanks for your quick reply
I have downloaded the latest mingw compiler and the configure command ran successfully
However, the build fails

codecs\qtextcodec.cpp: In function 'void setup()':
codecs\qtextcodec.cpp:269:16: error: expected type-specifier before 'QIconvCodec'
codecs\qtextcodec.cpp:269:16: error: expected ';' before 'QIconvCodec'
mingw32-make[4]: *** [tmp/obj/debug_shared/qtextcodec.o] Error 1
mingw32-make[3]: *** [debug-all] Error 2

mingw32-make[1]: *** [sub-src-make_first] Error 2
mingw32-make: *** [module-qtbase-make_first] Error 2

any idea on how to fix this?

Thanks

You are most probably using an outdated Qt5 (the mentioned error has been fixed in "Ic3c4ccce":https://codereview.qt-project.org/33691).

Either download the latest sources or, as I would recommend, clone latest from git.

I downloaded 32 bit windows mingw version of 5.0.1 yesterday and I get the same error when compiling my project.

I have the same problem exactly on Win XP. I downloaded the MinGW 32 bit version of Qt 5.0.1 install so MinGW, gcc, and g++ in the installed bin should all be up to date - I would think? ? ?

On another forum I found a single post that suggested to use the option arguments :

@
-no-qt3support CXXFLAGS="-fno-keep-inline-dllexport"
@

This worked on my system. It may work for yours as well Graham.
