I try to build a program with g++ under Cygwin. I added this libraries

Shouldn't that be '-lboost_system'? Run 'info ld' and search for
'--dll-search-prefix': 'cyg-' is a typical default prefix that
the '-l' option should recognize without your specifying it.
okay, thanks for this hint
/usr/lib/gcc/i686-pc-cygwin/4.5.3/../../../libcygwin.a(libcmain.o):(.text+0xa9):
undefined reference to `_WinMain@16'
collect2: ld returned 1 exit status
Does this thread
http://cygwin.com/ml/cygwin/2011-10/threads.html#00440
contain the answer?
no, sorry.
If this is a console application, does it have
an implementation of main()?
yes the signature of the main is in this example:
int main(int argc, char* argv[])
Or if it's a windows GUI application,
is WinMain() implemented in some object file passed to the linker?
No i don't use the WinMain() and I call the compiler / linker with -mconsole
but on 3 examples the error with the WinMain is shown, on other examples
everything works fine, so I don't understand it
Thanks
Phil
