When I use initialiseJuce_GUI(), the Juce GUI is not launching. My apologies in advance for the cross-post, folks, but I really need some help - I’m not sure where to put initialiseJuce_GUI(), or how it needs to be used. This is for an open source security tool that is freely available. The current version is working, but doesn’t compile on Fedora with a juce compile error. When I upgraded juce_amalgamated to the latest, I have some compile errors and found out from Jules that I need to use initialiseJuce_GUI. It compiles on fedora now, but the GUI doesn’t launch. Helping me with this will make Juce even more popular, being used in an open source security tool.
This is the function within a cpp file that is calling initialiseJuce_GUI(). The entire cpp file is below. What am I missing?:
void *startUCSniffJUCEGUI(void *){
int retval = startJUCE();
return NULL;
}
int startJUCE ()
{
initialiseJuce_GUI();
//char *argv[] = {"ucsniff.exe"};
//return JUCE_NAMESPACE::JUCEApplication::main (1, argv, new JUCEUCSniffApplication());
//const char *argv[] = {"ucsniff.exe"};
//return JUCE_NAMESPACE::JUCEApplication::main (1, argv);
}How does the call to initialiseJuce_GUI() know the name of the JUCEApplication, because the call to main used to work before, and it returned the JUCEApplication class name??
This is the relevant C program code and main within that code that is calling the function in the Juce CPP via a thread:
int rc = pthread_create(&threads[0],NULL,startUCSniffJUCEGUI,NULL);
if(rc){
printf("Error Creating thread for JUCE GUI : %d\n",rc);
exit(1);
}cpp code for JuceUCSniff.cpp:
#include "includes_juce.h"
#include "MainComponent.h"
extern int guiShutdown;
extern "C" {
void *startUCSniffJUCEGUI(void *);
};
