dev-cpp-users Mailing List for Dev-C++

I read in the e-mail of Per Westermark about drawn.c the existence of 
Gnu Visual Debugger. I tried to download from Internet but it isn't to 
the site (https://libre2.adacore.com/gvd/gvd-1.2.5-nt.exe) and now it is 
available only together with GNAT. Someone knows where is possbile to 
download gvd stand alone? Or other similar graphical debugger (in my 
experience the one included in DevC++  is not very stable).
Thanks
Alessandro

You did remember to compile without optimization? Adding debug information
but not turning off optimization makes for very interesting debugging,
since the compiler will rearrange the order of the generated code compared
to the order of the source lines.

Debugging an optimized binary is only meaningful in assemply mode, to look
for code code that isn't behaving correctly under optimization, i.e. that
is compiled with wrong flags (assumption of aliasing for example) or if
the compiler is suspected of generating incorrect (or bad) code.

Hi all,

Rodolfo sent me the version in which he added winsock.h and that compiled 
fine under Dev-C++. However, the GNU debugger was still skipping lines of 
code when I traced the execution of dcraw.c (which was the purpose of all 
this, so I could understand the various file formats its capable of dealing 
with). But thanks to Rodolfo's file, and a couple of questions on the 
Borland C++ Builder group, I managed to compile and run dcraw successfully 
under the recently released Borland Turbo C++, and its debugger is tracing 
every step of the code as it should and now I got a pretty good idea about 
all those raw file formats.

So, thank you all, because without your help I wouldn't have been able to do 
this.

Hi,

I could compille dcraw.c with dev-c++ (mingw compiler).  I just added 
#include <winsock.h> to dcraw.c and -lwsock32  to the linker parameters.

Rodolfo d'Ettorre
