Hello, Some days ago I have found the great compiler "gcc" in the web. But I have got three questions. I would like to create a IDE for C/C++. I have compiled a C++ script with following command line: g++ -c "d:\projekt c editor\files\hello_world_cpp.cpp" -o "d:\projekt c editor\files\hello_world_cpp.exe" But then I got a message including the message, that I have not got no acces for the file. I have got full acces! I hope you can help. The second question is: Is there any posibility (COM-Interface for example) to communicate with GCC? Of course my IDE needs a debugger. Or is there any posibility, that GCC can integrate a connection with my application? And the third question is: Does GCC support the creation of real windows in C? I found a tutorial, which describes how to create applications under Win32 with real windows in C. But GCC has given an error. I hope, you could understand me and you can help. Thank you!
