[Dev-C++] Executable size is huge

[Kevin S. <web...@ba...>]

Hi,
using a simple Hello World program and the appropriate compiler flags 
(-O3) and without any debug info the executable is about 440KB in size. 
The compiler doesn't seem to be doing any dead code removal. I remember I 
had this problem a long time ago when I used cygwin but I don't remember 
my solution.

Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/

[Dev-C++] ok, better formulation of the problem

[P.T. W. M. <pt...@ea...>]

Using this hand modified makefile:

CPP  = g++.exe
CC   = mingw32-gcc.exe
WINDRES = windres.exe
RES  = X01_private.res
OBJ  = object/main.o $(RES)
LINKOBJ  = source/main.o $(RES)
LIBS =  -L"C:/bin/cpp/lib" -mwindows
INCS =  -I"C:/bin/cpp/include"
CXXINCS 
=  -I"C:/bin/cpp/include/c++"  -I"C:/bin/cpp/include/c++/mingw32" 
-I"C:/bin/cpp/include/c++/backward"  -I"C:/bin/cpp/include"
BIN  = exe/X01.exe
CXXFLAGS = $(CXXINCS) -std=gnu99
CFLAGS = $(INCS) -std=gnu99

.PHONY: all all-before all-after clean clean-custom

all: all-before exe/X01.exe all-after


clean: clean-custom
	rm -f $(OBJ) $(BIN)

$(BIN): $(LINKOBJ)
	$(CPP) $(LINKOBJ) -o "exe\X01.exe" $(LIBS)

object/main.s: source/main.cpp
	$(CPP) -c source/main.cpp -S $(CXXFLAGS)

X01_private.res: X01_private.rc
	$(WINDRES) -i X01_private.rc -I rc -o X01_private.res -O coff

on the simple attached (automatically generated app) main.cpp where I 
completely removed the main.o lines and inserted a rule to make the asm 
source yields this console output:

C:\Documents and Settings\patrick\My Documents\Shop>make
g++ -I"C:/bin/cpp/include/c++"  -I"C:/bin/cpp/includ

*********************** output end

This error seems strange to me as I'm not asking for any .o file, and in 
fact deleted the main.o rule to see if I could get rid of this error, which 
was stopping me inside the GUI as well.

Again, my goal is simple.  I'd like to just be able to turn on the -S 
option and then get .s files as output, rather than asm in .o files.

Right now, I'm doing this merely to groke the GUI and see the relationship 
to the Makefile.win it creates, etc.

Anyway, if anyone can set me straight about this I'm grateful.  It just 
does not appear to be working the way I would expect.  I notice that in the 
Makefile.win created by Dev-Cpp, that it does not use a macro for the .o rule.

I assume what I want to do is possible with a standard makefile, and 
therefore should be possible with the Dev-Cpp GUI.  Maybe I need to 
manually enter an additional rule?

RE: [Dev-C++] write a startup code

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

There is nothing magic about it.

All you have to do is setup the processor registers. Then you may call the
_main function and perform the rest of the hardware initialization there.

What type of processor are you using? If it is a 386 or higher you might
have to initialize processor to proper memory mappings and then enter
protected mode before calling _main.

Re: [Dev-C++] -S solution to viewing .asm

[P.T. W. M. <pt...@ea...>]

Yes, I can successfully change the object/output directory, no problem.

The problem is that there is apparently no way to just have MinGW just 
output the asm file as .s, rather than .o, so it looks like an object vs. 
and asm file (without forcing it with the -o command option).

That is to say that when I throw the switch (-S in this case) I really want 
to see it output a .s file automatically, rather than .o.  Apparently, 
however, the GUI does not permit this as it puts in a non-removable -o 
option regardless mandating output be .o.  I even tried disabling this by 
editing the compile command with override, and removing the -o part.  If I 
do this, then it simply fails altogether.

So, I guess it is just a limitation and that if I want this behavior, I'll 
have to create and manage my own make file.

RE: [Dev-C++] write a startup code

[Smitha V. B. <smi...@so...>]

hi ..
thank you for your instant reply..
I am writing startup code for my gcc compiled program for SH on custom made
board. The code that is been generated is fine. But now, I want to add my
own startup code.
What i have to do..does I need to write a small piece of "free-standing"
code, i.e. it will contain its own startup code .
can u give some guidelines..
how i have to start

[Dev-C++] -S solution to viewing .asm

[P.T. W. M. <pt...@ea...>]

Hi,

Ok, after managing to read more of the manual I have found the reason I 
didn't see the .s file was a -o file command telling the compiler to save 
as .o anyway.

I really just want the compiler to use the appropriate extension, but 
suspect this is the result of my specifying a directory for 'object' files.

What should I be modifying to allow me to save output files to a 
sub-directory, but without mandating the extension so that the compiler 
will use the appropriate .s or .o as required.

Thanks, Patrick

[Dev-C++] gcc docs in other than ps

[P.T. W. M. <pt...@ea...>]

Hi,

I downloaded the gcc docs, but they are in PS formated on A4.

I used Acrobat's Distiller to convert them to .pdf, but the text is barely 
readable, and since it is in A4 format, I cannot easily print it.

I'm looking for the docs in some other format so that I might be able to 
better manipulate them into the form I need to be able to read it.

Where might I find some other format?  I have a FreeBSD machine at my 
disposal as well.

Thanks, Patrick

Re: [Dev-C++] Linking a Dev-C++ DLL using VC++.net

[<or...@vp...>]

Hi!

Have you tried using the library with a Dev-C++ project?
GCC compiled binaries can use MSVC DLLs very well. This is the purpose 
of MinGW anyway, to use msvcrt.dll (and others) from GCC binaries.
Your case however now is just the opposite (VC binaries using GCC DLLs), 
and I don't if it works, however (because of simple C code) it should.

Try it from a Dev-C++ project, that is similar to the VC++ project, and 
see if that works or not.

[Dev-C++] Linking a Dev-C++ DLL using VC++.net

[Dirk T. <d.t...@gm...>]

Help!

I'm new to this list and quite new to programming on Windows, so please=20
forgive me any ignorance.

I like Dev-C++ a lot and find it more usable in many respects than the=20
commercial M$ offerings.

My problem is as follow: I have a source-code (in plain C for gcc) of a=20
library I need to use in a Visual-Studio project (for the W32 gui).

I was able to successfully port (compile and link) the library into a=20
dll using Dev-C++ (current - good job, folks) and the dll projects type=20
(using declspec etc. for exports).

Then I created a small VC++.net project and included the import library=20
and headers. everything links fine but the test app crashes on the=20
first library call with a read access violation.

After much fiddling and reading I started loading the DLL and calling=20
some functions dynamically using GetProcAddress().
This works as expected and leads me to thinking that there is some=20
incompatibility in the import library.

Can it be the calling convention? I did not declare any and the=20
def-file created by Dev-C++ does not contain underscores nor=20
@<paramtersize> decorations.

It would also be an option to link statically against the GCC-built=20
library using VC++.
I tried that but also got nothing but crashes. Is that possible at all?

Note that I only use pure C, no C++ anywhere.

Any help is very much ap=FCpreciated!

Greetings,
Dirk

[Dev-C++] Question

[stephane w. <ste...@9o...>]

In the Compiler option, I must add "D:/Program =
Files/MPICH/SDK/Lib/mpich.lib" to the linker command line to use MPI.
But when I close and re-open Dev-C++, the command line is translated as=20
D:/Program Files/MPICH/SDK/Lib/mpich.lib
without "".
The compiler understand this as 2 phrases like this : D:/Program and =
Files/MPICH/SDK/Lib/mpich.lib.
How i can solve this problem ?

Thank.

Re: [Dev-C++] More Template Problems -- NewB

[Abdelkader G. <go...@li...>]

it's just a small problem with the type that you have declared: 

> typedef jme::Index<const int, const std::string > T_index;

So, T_index now is considered as an alias to the type jme::Index<const int, 
const std::string >

Consequently, accessing an attribute or a method that are not declared as 
static for this class has no sense. Perhaps you intention was to declare a 
variable which is an instance of T_index. In this case you should write 
this:
<old     code> T_index( i, name );
<correct code> T_index my_instance(i,name);
                       ^^^^^^^^^^^
and change also this:

<old     code> std::cout << T_index.getKey() << std::endl;
<correct code> std::cout << my_instance.getKey() << std::endl;
                            ^^^^^^^^^^^

Hi there,

Your code is well written, it should compile and run, just check that you 
have compiled correctly the 'file.C' (rename it to .cpp :) or delete all 
old *.o files and recompile all the project.
