QtCreator vs cmd.exe (not equal)
-
Thank you, sneubert, for your advices.
I am not sure that I have done exactly what you said, so I describe what I do.
I choose C++ Project, With qmake, without Qt. There are 2 “similar” types: 1) C++ Project, With cmake, without Qt; 2) C++ Project, With qbs, without Qt. I suppose you mean “With qmake” isn’t?“… check that you configure for the kit containing the mingw4.9 compiler. If you don´t have a kit, create a new one.”
Unfortunatly I don’t know how to check “mingw4.9 compiler”. I use default kit “KitSelection:Desktop Qt 5.4.1 MinGW 32bit”. And maybe, this parameter from Project Prpoperties can be interesting too
qmake.exe ProjectTestNoQt.pro -r -spec win32-g++File *.pro have a bit difference
LIBS += -L$$PWD/ -lUSTROYSTVO //not llibUSTROYSTVO and with pwdINCLUDEPATH += $$PWD/ // and this 2 strings(1)
DEPENDPATH += $$PWD/ // and this 2 strings(2)And these strings was placed before "headers +=.. ". But I moved them to the end of file.
include(deployment.pri)
qtcAddDeployment()But however I have the same errors like I had early.
Any ideas? )) I asked in third forum and still can’t solve my problem. (( So I am glad to see any your advice and idea. -
Hi and welcome to devnet,
What errors are you getting now ?
-
Thank you, SGaist , for your or attention.
I have some identical errors in different parts of code: “undefined reference to” and “more undefined references to”
For example:undefined reference to
SomeOneFunc(_dictionary_*, char const*, int)' . more undefined references toSomeOneOtherFunc(dictionary, char const, int)' follow.This SomeOneFuncs are described in file1.c and file1.h and they have no deal with *.a. (I am not totally sure but looks like that is true. As I said before I am not author of this code.)
Moreover there is exist one more error (last one)
C:/ProgramFiles/QtMinGW/Tools/mingw491_32/bin/../lib/gcc/i686-w64-mingw32/4.9.1/../../../../i686-w64-mingw32/bin/ld.exe: release/ FileMain.o: bad reloc address 0x14 in section `.text$ZStplIcSt11char_traitsIcESaIcEESbIT_T0_T1_ERKS6_S8[_ZStplIcSt11char_traitsIcESaIcEESbIT_T0_T1_ERKS6_S8]'
collect2.exe: error: ld returned 1 exit status
mingw32-make[1]: *** [release\ProjectTest.exe] Error 1
mingw32-make: *** [release] Error 2 -
The
bad reloc addresserror you get, maybe caused by linking files compiled with different compilers.
Do you build any part with a different compiler, or different version of gcc?
Sometimes such errors are the result of having multiple mingw installation.
You can compile from command line. Can you check the gcc dir withwhere g++? -
When I compile from command line I use shortcut “Qt 5.4 for Desktop (MinGW 4.9 32 bit)” (from Start->Programs->Qt MinGW). This shortcut has properties (target object.. don’t sure how to translate it correct. But I suppose you know what I mean. ) This is one row
C:\Windows\System32\cmd.exe /A /Q /K C:\ProgramFiles\QtMinGW\5.4\mingw491_32\bin\qtenv2.batAs I understand /A /Q /K is not important for compiler options. This is tenv2.bat file text: (4 rows)

echo Setting up environment for Qt usage...
set PATH=C:\ProgramFiles\QtMinGW\5.4\mingw491_32\bin;C:\ProgramFiles\QtMinGW\Tools\mingw491_32\bin;%PATH%
cd /D C:\ProgramFiles\QtMinGW\5.4\mingw491_32I don’t know how to check what QtCreator uses… Could you help me to know it?
Moreover…When I saw first time Qt example I had OS Windows 8.1 and MS Visual Studio 2010 and I didn’t know what does g++ means. So I downloaded and installed Qt (5.4.1 MSVC 2010, 32bit) (qt-opensource-windows-x86-1.6.0-8-online, http://www.qt.io/download-open-source/). :) A bit later I had understood that it isn’t what I need :). After that I downloaded and installed http://sourceforge.net/projects/mingw/files/Installer/ mingw-get-setup.exe (86.5 kB) [with Basic Setup mingw-developer-tolkit mingw32-base mingw32-gcc-g++ msys-base]
And the example works well with Windows cmd.exe without any bat-files or something else. But of course I set path to environment. After this I downloaded and installed Qt 5.4.1 for Windows 32-bit (MinGW 4.9.1, 856 MB) ( www.qt.io/download-open-source/ ). "G++..." command still works good from cmd.exe and g++ from previous installated MinGW (mingw-get-setup.exe).
But I tried to delete path from environment for installed MinGW (mingw-get-setup.exe) and g++ stopped work with Windows cmd.exe But g++ command works with shortcut “Qt 5.4 for Desktop (MinGW 4.9 32 bit)”.
Note: When I say “Windows cmd.exe ” I mean Start->Run->cmd.exe. Not shortcut with bat file and “path=…”. Moreover I don’t see in environment paths any folder for installed Qt 5.4.1 for Windows 32-bit (MinGW 4.9.1, 856 MB).
I didn’t build compile etc *.a library from this example. And I haven't got source code for it or any information about how it had been created too. -
There's absolutely no need to install anything from MinGW since it comes as an option when you use the installer. Use that one. If you really want to do console development on Windows, then use the provided link to setup the console. Otherwise you'll have to do it by hand. Don't modify the PATH environment variable by hand, that's the shortest way to a world of trouble.

Ок. Thank you for advice. I understand. But what should I do now for create QtCreator project without errors? Should I uninstall all Qt and MinGW and reinstall then only Qt (MinGW version)?
-
Since your install looks a bit messed up, yes, stat from clean
-
I have cleaned and reinstalled Qt. Moreover I installed Qt(MinGW) on other PC (without qt mingw etc before, but with MS VS2010).
In both case there are the same errors I have described. -
The bad realloc error ? Or the kit error ?
-

Yes, realloc and undefined reference.
undefined reference to SomeOneFunc(dictionary, char const, int)' .
more undefined references to SomeOneOtherFunc(dictionary, char const, int)' follow.
and
...bad reloc address 0x14 in section...
I said about it before. Nothing changed after reinstall. And I have the same errors on other PC too. -
What symbols are missing ?
-
Thanks for advices.
I have found the solve at Russian Qt forum.
http://www.forum.crossplatform.ru/index.php?showtopic=10432
Thanks to them.
Problem can be solved by renaming all *.c file in project into *.cpp file.
