Programming :: Dereferencing Pointer To A Shared Memory Struct?

Feb 5, 2011

I have what should be a relatively simple program (fadec.c) that maps a struct from an included header file (fadec.h) to a shared memory region, but Im struggling accessing members in the struct from the pointer returned by shmat. Ultimately, I want to access members in the shared memory structure with a globally declared version of the struct, shm__. Not only do I not know how to accomplish that, but I cant even seem to access members of the shared struct directly from the pointer itself (compiler complains about dereferencing pointer to incomplete type). Im at a loss and could use another set of eyes if you guys dont mind taking a gander:

Compile Errors:
tony-pc:/cygdrive/p/test> cc -o fadec fadec.c
fadec.c: In function 'main':
fadec.c:30: error: dereferencing pointer to incomplete type
fadec.c:31: error: dereferencing pointer to incomplete type

Programming :: Bizarre Compilation Error / Was Not Declared In This Scope?

Well, either it's bizarre or I'm going crazy. Here is a student's very simple linked-list implementation.

The problem is simply that when the list class is named "link", g++ complains:

Programming :: How Switches Controlling Code Compilation

Aug 28, 2009

I had been working on a CPP code for sometime now, without being aware that some parts of its code, especially security related were not being compiled. Problem was like my product did not work for SSL mode. On analysis, I found that some part of CPP codes inside a switch(ENABLE_SSL_LIBRARY)were not getting compiled at all. And also that this gets set when we do newgrp crypto command on the box. This left me without lots of doubts. I wanted to understand how these switches work and if this switch was propreitary to my code or something related to Linux.

My questions now are:
1. Switches like the one mentioned above, are they user defined, for my particular code or are they related to Linux/GCC or makefiles?
2.If a user can define such switches to control code compilation, then need to know the concepts/procedures behind it. How is it done ?

Kindly excuse if these are very very basic. But since I could not get proper stuffs on google, I thought I should ask some experts here who could either explain me or point me to appropriate resources (links of articles / tutorials)

Debian :: Bluetooth Menace - Compilation Error ?

Jan 11, 2011

I'm running debian lenny, kernel.

I get the error "could not open obex://some_long_MAC_address...please do something..." when I try to browse my samsung using bluetooth.

My phone's service list indicates all but one service item(modem) are present. I can send stuff to it but not the other way round. Someone told me that debian distros have bluetooth problems.

Also, when compiling kernel and 2.6.37-etc, I get the undisputed error concerning the 'lguest' feature. How do I turn it off?
