stl fstream and macros on vs7

while working with visual studio 2003 / 7, c++, fstream, log files and macros, like the following:

#define LOGMACRO (format_string, ...) log (__FILE__, __LINE__, format_string, __VA_ARGS__)

got some errors:
error C2059: syntax error : '...'
error C2061: syntax error: identifier '_DebugHeapTag'
xdebug(29): _CRTIMP2 void * __cdecl operator new(size_t, const std::_DebugHeapTag_t&, char *, int)
_THROW1(std::bad_alloc); // allocate from the debug CRT heap

the solution was in 4 steps:

1. replacing all stl include files matching the pattern:
#include <string.h>
#include <fstream.h>

with header files without '.h' in their names, ex:
#include <string>
#include <fstream>

2. putting some parantheses around the parameters in the macro def. value, like:
#define LOGMACRO (format_string, ...) log (__FILE__, __LINE__, (format_string), __VA_ARGS__)

3. replacing '...' and '__VA_ARGS__' with a simple parameter. vs7 does not support varargs in macros.
#define LOGMACRO (format_string, args) log (__FILE__, __LINE__, (format_string), (args))

4. putting the fstream include in the last line of stdafx.h, removing from any other location in the source code like below.
#include <fstream>
using namespace std;

In addition to the things described above, here is a nice macro tutorial:

SIG33 and the other POSIX RT (runtime) signals

Here is a tutorial about POSIX signals.

from an other source:
if you get "Program received signal SIG35, Real-time event 35.", this is due to a directory changing rather than a bug. You can disable these events and then c(ontinue) (the signal number may vary):

(gdb) handle SIG33 noprint nostop
(gdb) c

there is also mentioned strace :
$ strace -p PID

$ strace -p PID -t

gcc, dlopen and cdecl

Here is a small tutorial about loading .dll-s (.so-s) under linux and the solution to the mangling problem.

shortly : to make available your function written in c++ for dlopen use extern "C" before the function header :

extern "C" void hello() {
std::cout << "hello" << '\n';

gcc personality problems

gcc - the c compiler - has a pretty funny error, when you try to compile a non c file with it:

undefined reference to `__gxx_personality_v0'

one has to rely on the "personality" of g++ to keep the intergrity of the gcc self-esteem.
