I am trying to create a BB10 cascade project using the Momentics IDE version 2.0, and I need a project to use the GNU standard library instead of Dinkumware (because I have external libraries compiled from arm-unknown-nto-qnx8.0.0eabi-g++that only support gnu std).
In the IDE, I changed Project Properties-> C / C ++ Build / Settings / Runtime to “C ++ GNU with Exceptions”. However, when I run a simple project with a static library (.a file) created by me (only with a header containing the constructor, object std::string, setter and getter (for the object) and the corresponding cpp file) I get a segmentation error when I do this:
testnamespace::testclass *object = new testnamespace::testclass();
std::string test = "Hello";
object->setText(test);
delete object;
I think this error occurs because the library was compiled with gnu std and the project was compiled with Dinkumware.
I checked the inclusion paths and I found out that
C:\bbndk\target_10_1_0_428\qnx6\usr\include
contained before
C:\bbndk\target_10_1_0_428\qnx6\usr\include\c++\4.6.3
Also, the command used by makefile to compile the cpp files in the project qcc -Vgcc_ntoarmv7leinstead qcc -V4.6.3,gcc_ntoarmv7le_gpp(support flag for gnu stl).
Am I doing something wrong? Some configuration missing?
I really need to use GNU STD instead of Dinkumware in my BlackBerry project, but I cannot figure out how to do this.
EDIT:
I made some changes to my project and fixed some problems.
I added this to my .pro file
QMAKE_CXX = qcc -V4.6.3,gcc_ntoarmv7le_gpp
QMAKE_CC = qcc -V4.6.3,gcc_ntoarmv7le
QMAKE_LINK = qcc -V4.6.3,gcc_ntoarmv7le_gpp
QMAKE_AS = qcc -V4.6.3,gcc_ntoarmv7le_gpp
LIBS += -lc -lm -lcpp -lstdc++ -Bstatic ../libs/libteste.a -Bdynamic
(The LIBS team was already there, but I decided to put it here so you can understand how I link libraries).
Now I have the following code:
testenamespace::TesteClass *temp = new testenamespace::TesteClass() ;
std::string teste = "Hello";
temp->setTesteString(teste);
QString qsr = QString::fromStdString(temp->getTesteString());
qDebug ("String in the object: "+qsr.toLatin1());
delete temp;
, delete temp;, :
