How can I get the command line GCC uses to invoke ld? I have a problem for an AVR target where GCC apparently adds a linker option which I am trying to override, so I would like to look at the exact options GCC uses for ld. ...
Hi I'm trying to use the boost library in my code but get the following linker errors under Sparc Solaris platform. The problem code can essentially be summarised to: #include <boost/algorithm/string.hpp> std::string xparam; ... xparam = boost::to_lower(xparam); The linker error is: LdapClient.cc:349: no match for `std::string& ...
I've been working on some older C code. I found out that there are quite some POSIX calls that are now outdated and marked deprecated in the manual pages. What's the best way to check if there are still deprecated POSIX calls in your code? I'm thinking of either: special gcc warning options. some kind of lint tool detecting these call...
I plan on using GCC more (Linux and Windows) and I was wondering if there's an equivalent of the MSVC debug heap and the STL checks available for the GCC CRT and STL. I already know about tools such as Valgrind, but I'm looking for something built in the libraries. ...
My target is to analyze and learn in details of compiler development techniques. Here I want to add a keyword in gcc and see how it works. ...
I have a perl script I'd like to filter my cpp/h files through before gcc processes them normally -- basically as an extra preprocessing step. Is there an easy way to do this? I realize I can feed the cpp files to the script and have gcc read the output from stdin, but this doesn't help with the header files. ...
Are integers in C assumed to be handled by a hardware spec or handled in software? By integer, I am referring to the primitive "int" The underlying idea being that if integers in C are not hardware dependent would it be a violation of standard to have gcc implement different integer handlers. This way you could have your traditional 32...

I have a Visual Studio C++ based program that uses pre-compiled headers (stdafx.h). Now we are porting the application to Linux using gcc 4.x. The question is how to handle pre-compiled header in both environments. I've googled but can not come to a conclusion. Obviously I want leave stdafx.h in Visual Studio since the code base is p...
This seems like it should be really simple. I compiled a library in Qt (this newmat library), and produced the file libnewmat.a. Now I need to integrate this library into another project but I just can't get it to work. I've tried a few different things with the LIBS variable in my .pro file including: Win32:LIBS += libnewmat.a #libr...
Hello, I'm having a macro like this ( not exactly, but function is quite equivalent): #define STRUCTMEMBER(Member,Value) GlobalStructInstance. ## Member = Value ... STRUCTMEMBER(Item,1); This works perfectly in Visual C++, but gcc 3.4.5 (MingGW) yield the following error: pasting "." and "Item" does not give a valid preprocessing to...
I have a C function that contains all the code that will implement the bytecodes of a bytecode interpreter. I'm wondering if there is a way to align segments of the compiled code in memory on fixed size boundaries so that I could directly calculate the address to jump to from the value of the bytecode? Sort of the same way an array work...

I am using the function gets() in my C code. My code is working fine but I am getting a warning message (.text+0xe6): warning: the `gets' function is dangerous and should not be used. I want this warning message not to pop up.Is there any way? I am wondering that there might be such possibilities by creating a header file for disabli...
How can I make gdb interrupt (like in breakpoint) the program at the point where an exception is thrown, and interrupt again on rethrows and beginnings of the relevant catch blocks? ...
So, when we do the following: #include <stdio.h> versus #include "myFile.h" the compiler, GCC in my case, knows where that stdio.h (and even the object file) are located on my hard drive. It just utilizes the files with no interaction from me. I think that on my Ubuntu Linux machine the files are stored at /usr/include/. How does...
I'm trying out the solution to a question about specialized template classes. This code with a compiles fine in g++, but throws up linker errors when compiled with gcc.
