Creating makefile's for DLL's!!! 1

[ctoma2005]

Hy. I have to create a makefile for buiding a DLL. The DLL contains only a resource file(jpg's and waw's). The game i am working on is written in C++ builder. I want to create a makefile and using project -> export_makefile doesn't work(it gives me an "access violation" when I type "make -f data.mak" at the command line). Somebody help me!! Thanks in advance.

That helps me (I learned more about makefiles), but it doesn't help me .Let me be more explicit about my problem:
I have some pictures and sounds and a data.rc with their id's. I compile data.rc and make a data.res. From that file I want to create the dll, but not with cbuilder. I want to use a makefile. The problem is that I get a "share access violation" when I open the project, but I can pass this problem in the IDE. But when the makefile compiles the file, it can't pass the error. I have no idea from where the error comes, since in the IDE it is not fatal! (I just press OK).
It is not very eficient to make a makefile for such a little project, but that's my job .
If someone can help me....please!!!!

This is the exact error: "Error creating form: Access violation at address..." (I understand the error, since the project is a dll). I tried to make just a source code, not a project, but I still get an fatal error when making the makefile.

 

[tsh73]

would you post your makefile so we could make some mode informed guess? )

Ok.
The source code looks like this:
" #include <windows.h>

#pragma resource "data.res"
#pragma argused
BOOL WINAPI DllEntryPoint(HINSTANCE, DWORD, LPVOID)
{
return TRUE;
}
"

The makefile looks like this:
"
.autodepend
resources.dll : main.cpp
bcc32 -WDR main
"

The .rc file looks like any resource file (with id's for
every picture and sound).

From this files I have to create a compile.bat file, witch
should look like this:
"
BRCC32 data.RC
make -f dll.mak
".
I think I didn't do anything wrong but the dll is created, but it's no good. When compiling the .bat file, it
gives me an error: " Fatal: access violation. Link terminated ".
I get this kind of error even if I make a dll project in C Builder, but there I just press OK.

I found some posts on this site - check them out

Ok... I read the posts, but I already know how to create the dll and use the stored jpg's. My problem is with creating the makefile for the JPG!!I want to use a simple .bat file to create the dll, that is why i need the makefile.As I said, when typing "make -f data.mak" it gives me an error that I get when building the dll project in C buider, but it's not fatal. Maybe I'll figure it out somehow... Thanks!

You probably should be adding the .res file (generated by brcc32) to the dependencylist of resources.dll like:

data.res: data.rc
    brcc32 data.rc

resources.dll: main.cpp data.res
    bcc32 -WDR main

(Untested script)

This should force both data.rc to be compiled to data.res and main.cpp + data.res into main.dll (!!!) Adding -eresources to the bcc32 line should resolve that (also untested)

Hmmm....this doesn't work either...
It still gives me the error "Fatal: Access violation. Link terminated" when typing "make -f data.mak". I see that the error comes from "main.cpp", and that the .res file and the .mak file is good. I think I need some option when building the .cpp file (maybe something like "silent" compiling, to try to bypass some errors/warnings).
I just realised that making that DLL doesn't worked in C Builder neither if I don't press "release" from
project->options. Maybe I need to do that but I can't tell the make command to do that!!
You don't have to loose more time with this problem, since I don't have to do this right away...but I am very curios to find the answer...

using your codes, I got main.dll compiled no problem at all. I used Borland free command line tools (BC++5.5)
If some spaces are missing make says something like "Error dll.mak 4: Command syntax error", but no any violation.
makefile I used (and got main.dll ):

.autodepend
resources.dll : main.cpp
   bcc32 -WDR main

other one, to get it named resources.dll:

.autodepend
resources.dll : main.cpp
  bcc32 -WDR -eresources main

I wonder if it's just "make" bug - check if Borland site has an update may be?

You are proably right. I'm going to download the free compiler from Borland later. Thank's very much for your time.
