[SOLVED] qtCreator doesn't build my project since I update to Mountain Lion

rikytres

In /usr/bin i can't find any file that contain "g++", "clang" or "gcc" in the name.
I think the problem will be resolved only with re-installing xcode...

I'm download it and in a few minutes i will do it... ;)

rikytres

Ok... I failed again...
I found out the g++ and gcc comand in /Developer/usr/bin/ and i set they as manual in tool chains.
I set "Compiler path" as /Developer/usr/bin/g++ and "Debugger" as /Developer/usr/bin/g++ too... Is it correct?

tobias.hunger

No, the debugger is called gdb. It will most likely be in the same directory as g++.

rikytres

And then is somethig like this?
Compiler path: /Developer/usr/bin/g++
Debugger: /Developer/usr/bin/gdb

right?

rikytres

I done it and now qtCreator can find the compiler.

But now I have an other problem... The compiler can't find the "basics" libraries like <iostream> or <string>.

I don't know what i can do...

This is the compile output log:

DISCLAIMER: use at your own risk and don't blame me if this procedure deletes precious files from your machine etc! :-)

Let me tell you what I did when updating from Snow Leopard to Mountain Lion:

Uninstalled Qt SDK using the respective option at SDK's updater.
Installed the latest XCode from Mac App Store.
From XCode, from the menu XCode --> Preferences --> Downloads, I downloaded Command Line Tools.
I reinstalled Qt SDK.

rikytres

I decided to do what you suggested... but i start from download last version of Xcode and then download the command line tools...

Then I deleted the QtSDK and I'm gonna to re-install it...

rikytres

The situation start to be very stressful... -_-
I reinstalled QtCreator, and now QtCreator can see all the compiler.

But...
when I open my project and compile it the compiler return me the follow errors...

../CalcolatriceSensibile/mainTest.cpp: In instantiation of 'std::basic_ostream<_CharT, _Traits>& std::operator<<(std::basic_ostream<_CharT, _Traits>&, const std::basic_string<_CharT, _Traits, _Alloc>&) [with _CharT = char, _Traits = std::char_traits<char>, _Alloc = std::allocator<char>]':

make: *** [mainTest.o] Error 1

I can't understand why this error...

rikytres

In particular the compiler give this error three times at the same row's code...

/Users/TresMac/Developing Project/C++/CalcolatriceSensibile-build-desktop-Desktop_Qt_4_7_4_for_GCC__Qt_SDK__Debug/../CalcolatriceSensibile/mainTest.cpp:16: error: explicit instantiation of 'std::basic_ostream<_CharT, _Traits>& std::operator<<(std::basic_ostream<_CharT, _Traits>&, const std::basic_string<_CharT, _Traits, _Alloc>&) [with _CharT = char, _Traits = std::char_traits<char>, _Alloc = std::allocator<char>]' but no definition available

rikytres

I found that tis problem come out when i use the operator << with cout on a std:.string variable.

For exemple this code give mi problems:
@#include<string>
#include<iostream>
std::string exemple = "exemple";
std::cout<<exemple;@

zetavision

I have the same operator << problem. Does Anyone know how to solve it?

garrgravarr

Yes!!

I had the same problem with the
"explicit instantiation of 'std:basic_ostream<..'"

I tried out the flags that Qt used to compile a simple main routine. Seems it works if you say
-mmacosx-version-min=10.7
instead of
-mmacosx-version-min=10.5

There are no sdks for 10.5 or 10.6 on Mountain Lion and XCode 4.4!

Hope that helped.

cheers,

tim

garrgravarr

btw, the entries with

-mmacosx-version-min=10.5

can be found in

$QTDIR/mkspecs/common/g++-macx.conf

.

cheers again...

zetavision

Great! I just found that conf. It works now. Thanks a lot. :)

rikytres

Perfect!! Now it works!!
Thanks a lot!

gosuperninja

Changing the mkspec file to -mmacosx-version-min=10.5 worked for me.

This one was real obscure. Does anyone have reason why this would break std iostream functions? At first I thought it was change in the gcc version with Mountain Lion.

Also, this appears to only effect gcc. Clang doesn't seem to have a problem with min-version is seto to 10.5

tobias.hunger

Did you guys "file a bug report":http://bugreports.qt-project.org/ ? This needs fixing in Qt.

JMLA

This is nice, but on my MacBookPro with ML (and a brand new XCode) I still get an error like

11:09:29: Configuration unchanged, skipping qmake step.
11:09:29: Could not start process "make" -w
Error while building project ImportMML (target: Desktop)
When executing build step 'Make'

What do you recommend ? Thanks ? jm

gosuperninja

JMLA, In the latest xcode the command line tools aren't installed by default. Look in Xcode->preferences->downloads. Select "Command Line Tools". Once you do this you may need to re-open QtCreator. But if this is the problem I would have expected Qt to complain earlier about not finding the tool chain.

JMLA

Thanks gosuperninja! It probably helps. Nevertheless the error code is now as below
(I turned back to one of the QT basic drawing examples, that has always been working!)
I am afraid I might be forced, to continue my work, to go for a while through Parallels... (:-(
(I have added on Qt Creator/Preferences.../Build & Run/Manual GCC with correct paths)
