I need to link my C++ programs against a couple shared libraries which generate way too much output to std::cout and std::cerr rendering them both useless for my uses. I have access to the C++ source code of these libraries, but cannot modify them. Is there a way to redirect their output to a different stream or suppress it when linked ...
This is related to an issue I have been discussing here and here, but as my investigations have led me away from the STL as the potential issue, and towards "new" as my nemisis, I thought it best to start a new thread. To reiterate, I am using an arm-linux cross compiler (version 2.95.2) supplied by the embedded platform vendor. When ...

I am moving a C++ project from Windows to Linux and I now need to create a build/make file. I have never created a build/make file before. I also need to include Boost libraries to make it more complicated. It must also be a makefile and I need to learn how to create makefile anyway, so CMake and SCON are out. IDEs are also out because o...

Hi, I have a ptrace code for a AIX machine, but want to port it to PPC-linux machine. I was able to figure out the respective ptrace requests on ppc-linux (like for reading registers PTRACE_PPC_GETREGS). However, I am unable to write to the registers, using the SETREGS call. Can there be any particular reason for this? Also, I found ...

I have a little USB-powered light. I'd like to be able to turn it on and off with software. I'll be attaching it to a Linux computer. I have an Atmel ATtiny2313 from a previous project, but I'd rather do this with a simple hack than repurpose my microcontroller. Is this possible? I suspect this can't be done as the computer won't talk t...

For instance: int main(){ a(); b(); } void a(){ c(); } The tool gives out something like: a----- c------ b------ ...
