Ubuntu 12.04: Installing MonoDevelop “broken packages”/”unmet dependencies” error
I am very new to Linux, so please forgive me if the answer to my question is obvious. Since I am running an ARM device and can’t install wine, I am trying to install Mono/Develop. The problem is, whenever I try to install any of the Mono packages, I am greeted with a huge block of “unmet dependencies.” For example:
SIGALRM, interval timers and problems with sleep()
I am working with porting one of our embedded microcontroller libraries to linux and writing a python wrapper around it. One of my low level modules depends on a callback that gets called every 10ms. This callback counts up software timers that each have callbacks of their own. These timers are used all over our library and while they don’t
__builtin_return_address returns null for index >0?
I want to get the return address of the caller function. I’m using __builtin_return_address() funtion, but if I give index value greater than 0 it is returning NULL. Please help me with this or tell me any other function to get the same. Answer See this answer to a related question. __builtin_return_address is GCC and processor specific (also available in
cmake linking shared libraries on ubuntu
Hi I am having problems with linking two libraries on ubuntu using cmake 2.8.12 Directory structure CMakeLists.txt for lib1 This builds fine. Then for lib2 I have the following CMakeLists.txt Here I get Linking CXX shared library ../build/liblib2.so /usr/bin/ld: cannot find -llib1 I am not clear how to correctly link these two shared libraries using CMake. Anyone an idea what
Process management code behaves different on Linux and Windows – Why?
(Context) I’m developing a cross-platform (Windows and Linux) application for distributing files among computers, based on BitTorrent Sync. I’ve made it in C# already, and am now porting to C++ as an exercise. BTSync can be started in API mode, and for such, one must start the ‘btsync’ executable passing the name and location of a config file as arguments.
What does `OBJECTS = $(SOURCES:.cpp=.o)` mean in a makefile
I am going over this tutorial and it has something like this I am not sure if I understand the document and would appreciate it if someone could explain the last two statements. Here are my three questions regarding Makefile Question 1 : Whats the difference between and It says that the second case only works if .cpp files exist
Shared library on Linux and -fPIC error
I am trying to compile a shared library in Linux using a Makefile created with Cmake, but running make I obtain the following error: I provide the following command in the CMakeLists.txt in order to say that I want a shared (.so) library: add_library(cpp-lib SHARED ${CPP_FILES}) What else do I need to specify in order to avoid the -fPIC error
Retrieve path of symbolic link
I want to store the path of the file the symbolic link is pointing to into bufff. This works with my current implementation using readlink but it grabs extra data I don’t need because my bufsize is arbitrarily valued. I’m not sure how to size it according to the path of what the symbolic link points to because all I
Why does QCoreApplication call `setlocale(LC_ALL, “”)` by default on Unix/Linux?
I think that it’s safe to say that C locales are universally recognized as a bad idea. Writing an application that tries to parse or write text-based machine formats (which happens quite often) with C standard library functions gets near-impossible if you have to account for locale being set to anything different than “C”. Since locale is normally per-process (and
