Re: FW: [Dev-C++] Execution Problem

[Ray K. <kul...@wr...>]

fflush(stdin) isn't portable either, so that should probably be replaced  
with cin.ignore(8) or something. (with the argument being greater if you  
anticipate more than 8 chars of garbage in the stdin queue).

[Dev-C++] CoCreateInstance(..) errors

[Mark A. <am...@ho...>]

Hi Steve,

I'm using your suggestion, but it has no effect.
I still get an error from CoCreateInstance: 0x800401F0
It is CO_E_NOTINITIALIZED
'Failed to connect to server'

Surfing the internet results in hints that it may have something to do with 
'MsiInstaller', 'Events'.
'Exchange Server 5.5 Service Pack 2 (SP2)', 'CoInitialize has not been 
called'.

I tried using OleInitialize(..) or CoInitializeEx(..) but these crash!

I've now found the solution!
I use CoInitialize(NULL) in stead of CoInitializeEx(..)

Thanks for your help by the way :)

greetings,

Mark Ament

Per,

You're quite right.

Replacing "C:\Dev-Cpp\lib\libole32.a" with "-lole32" in the Parameters - 
Linker box has resolved the issue.

Hi Mark,

I'm using COM without any problems.

I'm using the libraries that came with Dev-Cpp - Try using 
Dev-Cpp\lib\libole32.a. This should work fine.

Re: FW: [Dev-C++] Execution Problem

[lordSauron <lor...@gm...>]

yes that is a good point.  You really should use ignore() or something
like that as opposed to system() commands because they are deathly
non-portable.  Making them portable is really a pain too.  However,
system() commands are necessary in certain situations so don't shelf
the idea entirely.

Re: [Dev-C++] Newbie question on issue / bug reporting

[Per W. <pw...@ia...>]

Note that Libs=3D is empty and that the linking is done using the full
library name (excluding path).

Note that the libraries are not specified with the -l parameter, so gcc
will not care about any library paths (-Lxxx).

An expected link line should have looked like:

gcc ... -L"C:/Dev-Cpp/lib -lole32 -loleaut32

Sudhir,

Thanks for your help. However this does not address the issue.

The first approach to adding a library via the IDE is to use the "Add
Library or Object" dialog. Using a standard library produces the
following entries in the .dev file:-

[Project]

Libs=

Linker=../../../../../Dev-Cpp/lib/libole32.a_@@_../../../../../Dev-Cpp/lib/liboleaut32.a_@@_

This compiles fine. However the entries use a relative path from the
project directory to the library directory. In other words moving the
project directory will break the build. This is not good.

By editing the entries in the "Linker" box of the IDE we can ad the full
path in. This improves the situation. The .dev file now looks like this

[Project]

Libs=

Linker=C:\Dev-Cpp\lib\libole32.a_@@_C:\Dev-Cpp\lib\liboleaut32.a_@@_

This also compiles fine. However the dev file now contains full
addresses for all libraries. Again this is a portability issue. This may
also cause problems with large projects due to shell limitations on the
command line length.

The correct solution is to only add the library name. This produces the
following entry in the .dev file

[Project]

Libs=

Linker=libole32.a_@@_liboleaut32.a _@@_

This is now portable. However is does not compile. The compile log is as
follows:

Compiler: Default compiler

Building Makefile: "C:\Documents and Settings\Steve Higham\My
Documents\Dev\ConsoleTest\Makefile.win"

Executing make clean

rm -f main.o ConsoleTest.exe

g++.exe -D__DEBUG__ -c main.cpp -o main.o
-I"C:/Dev-Cpp/lib/gcc/mingw32/3.4.2/include"
-I"C:/Dev-Cpp/include/c++/3.4.2/backward"
-I"C:/Dev-Cpp/include/c++/3.4.2/mingw32"
-I"C:/Dev-Cpp/include/c++/3.4.2" -I"C:/Dev-Cpp/include" -g3

g++.exe -D__DEBUG__ main.o -o "ConsoleTest.exe" -L"C:/Dev-Cpp/lib"
libole32.a liboleaut32.a -g3

g++.exe: libole32.a: No such file or directory

g++.exe: liboleaut32.a: No such file or directory

make.exe: *** [ConsoleTest.exe] Error 1

Execution terminated


I don't understand why this fails. The -L switch identifies the correct
directory (C:/Dev-Cpp/lib) and the lib names are correct. This is the issue.

It's probably not the most important issue in the world. But it would be
nice to resolve it.

Kind Regards,

Steve

[Dev-C++] Windows, COM, CoCreateInstance and OleInitialize

Secondly: in the menu 'Project' -> 'Project Options' --tab-> Parameters =

The problem is that CoCreateInstance never succeeds in creating an =

in crashing!

I hope this problem can be solved to meet the important requirement of =
using COM in DEV-C++ !

 Sounds more like a missing 'system("PAUSE");' statement.  If the input

hi,

  In regard to your first issue:
=================================

   If your library doesn't resides in default library
path, you can alternativily add the directory where
your library files resides  by adding "-L<dir_name>"
to "additional commandline parameters" for c/c++
compiler or adding the the directory in the
"directory" tab in "project options" .Now link the
required library by adding "-l" option in the
"parameters" tab .If you want to link "libXYZ.a" then
the linker parameter will be "-lXYZ"


e.g , you want to link with "c:\lib\libXYZ.a" then
1.)add "-Lc:\lib" to compilier paremeters or add the
"c:\lib" directory in  library directories.

2.)add "-lXYZ" in the linker options.


  Pardon for my english.

Re: [Dev-C++] add lib

[Per W. <pw...@ia...>]

Since you are running Dev-C++ on a Windows machine and the used compiler -
MinGW - is a special version of the gcc compiler, you can select the
simplest solution:

#define IBPP_WINDOWS
#define IBPP_GCC
#include "ibpp.h"

Note however, that adding the #include line in your source file does _not_
add a library to your project. If ibpp.h has the implementation code in a
library, you must also add a reference to this library to your project so
that the linker will link in the library.

I would rather suggest you download and install wxDevCpp, from

It is a version of DevCpp with the wxWidgets libraries already

anyone have any information or idea...

  What I have noticed ,on windows the memory managment

is not that good as compared to OSes like LINUX .

  So what I personally recommend is to try an external
memory manager with your programs.But be warned ,in
some cases their use may lead to system instablity!
  
  I use 7-max < www.7-max.org > , an application
accelerator from the maker of 7-zip . It is fairly
stable and give the performance boost of 5 to 10% on
my system. Just attach 7-max to the memory hungry
application and notice the diffrence.

  In the case of dev-c++ , I achieved best results by
attaching 7-max to the gcc compiler exe (gcc.exe etc.)

instead of attaching it with dev-c++ exe.
