compiling CloudCompare in debug mode

[zhuhaixiong]

hello，when I compile cc in debug mode，It occurs some problem such as：
93 IntelliSense: "void (*)(GLenum source, GLenum type, GLuint id, GLenum severity, GLsizei length, const GLchar *message, GLvoid *userParam)" 类型的实参与 "GLDEBUGPROC" 类型的形参不兼容 e:\study\project\trunk-2.6.2\trunk-2.6.2\libs\qCC_glWindow\ccGLWindow.cpp 605 26 QCC_GL_LIB
错误 65 error LNK1104: 无法打开文件“..\libs\qCC_glWindow\Debug\QCC_GL_LIBd.lib” E:\study\project\trunk-2.6.2\cmake\ccViewer\LINK ccViewer
错误 92 error LNK1104: 无法打开文件“..\libs\qCC_glWindow\Debug\QCC_GL_LIBd.lib” E:\study\project\trunk-2.6.2\cmake\qCC\LINK CloudCompare
错误 32 error C2664: “void (GLDEBUGPROC,void *)”: 无法将参数 1 从“void (__cdecl *)(GLenum,GLenum,GLuint,GLenum,GLsizei,const GLchar *,GLvoid *)”转换为“GLDEBUGPROC” E:\study\project\trunk-2.6.2\trunk-2.6.2\libs\qCC_glWindow\ccGLWindow.cpp 605 1 QCC_GL_LIB
my software version is：VS2013+QT5.4+CMAKE3.4+trunk2.6.2
but there is no problem when I compile in release mode;
there is either noproblem when i compile trunk2.7 in the same condition.
how can i correct this problem!

In fact CC only supports Qt 5.5+ now. But the differences are small, and mostly in debug mode.

You should either use Qt 5.5 or comment the part where QOpenGLDebugLogger is initialized in ccGLWindow (line 761).

[zhuhaixiong]

line761 is “void ccGLWindow::resizeEvent(QResizeEvent *evt)”
on the one hand,you means I shoud makes some changes on ccGLWindow.cpp(line761)？
can you teach me how to change by detail?
i am a rookie in cc
on the other hand,you means i should change QT5.4 to qt5.5?right?

[zhuhaixiong]

another problem :dose QT5.5 contain opengl?

[daniel]

Yes.

[daniel]

The simpler would probably be to upgrade Qt and use 5.5 version.

thanks for you help，I have substituted the debug initilizing code in trunk 2.6.2(ccGLWindow.cpp line 624):
glEnable(GL_DEBUG_OUTPUT);
glEnable(GL_DEBUG_OUTPUT_SYNCHRONOUS);

//int value = 0;
//glGetIntegerv(GL_CONTEXT_FLAGS, &value);
//if ((value & GL_CONTEXT_FLAG_DEBUG_BIT) == 0)
//{
// ccLog::Warning("[3D View %i] But GL_CONTEXT_FLAG_DEBUG_BIT is not set!");
//}

glDebugMessageControl(GL_DONT_CARE,GL_DONT_CARE,GL_DONT_CARE,0,NULL,GL_TRUE);
//glDebugMessageControl(GL_DONT_CARE,GL_DEBUG_TYPE_OTHER,GL_DONT_CARE,0,NULL,GL_FALSE); //deactivate 'other' messages
glDebugMessageCallback(&GLDebugCallback, this);
by
trunk2.7 debug code(line761):
QOpenGLDebugLogger* logger = new QOpenGLDebugLogger(this);
logger->initialize();

connect(logger, SIGNAL(messageLogged(const QOpenGLDebugMessage&)), this, SLOT(handleLoggedMessage(const QOpenGLDebugMessage&)));
logger->enableMessages();
logger->disableMessages(QOpenGLDebugMessage::AnySource,
QOpenGLDebugMessage::DeprecatedBehaviorType
| QOpenGLDebugMessage::PortabilityType
| QOpenGLDebugMessage::PerformanceType
| QOpenGLDebugMessage::OtherType);
logger->startLogging(QOpenGLDebugLogger::SynchronousLogging);
/*glEnable(GL_DEBUG_OUTPUT);
and the problem maybe solved,because I has complile 2.6.2 in debug mode by qt successfully;
I will compile it in VS2013 in debug mode later.
thank you very much
