EQEmu DEV-C++ Howto (updated for 5.5DR1)

[Tertiary]

Here is a HOWTO to get EQEmu 5.3DR2 (01/01/2004 version) to compile
with Bloodshed Dev-C++ / mingw.

http://www.rama.demon.co.uk/EQEmu-Dev-C++.zip

Most of the changes were trivial. The two biggest headaches were:

1) Dev-C++ won't by default link against the mysql libraries

I have included instructions on how to create a libmysql.a

2) vsnprintf would SIGSEGV every time.

In the end I found a portable version of vsnprintf written in C
which I have included in the zip, and included in the HOWTO details
of where to put #ifdefs to use this version when compiling under Dev-C++.

I have also included .dev files for Emusharemem/world and zone (similar to VS .NET's .SLN fies).

I have only tested briefly under minilogin and it seems stable enough.

EDIT: The following added for 5.5DR1

The source tree for 5.5DR1 with Dev-C++ changes already made is available here:

www.rama.demon.co.uk/5.5DR1DevCPPSource.zip

I found out why vsnprintf wasn't working, so the 5.5DR1 zip no longer uses the 'portable vsnprintf', rather there are changes to allow the standard vsnprintf to work. As a result, any bugs (such as non-functioning #npcspawn add) relating to the use of the portable vsnprintf should be gone.

Great contribution!!!

Let me know if you get it to work

[Shadow-Wolf]

well sadly it didn't compile right =(
here are the errors i get:
86 C:\eqemu\5.3dr2dev\common\debug.h

Thanks Shadow-Wolf. Give me a day or two and I will see if I can figure out what is wrong. BTW can you give me a link to the EQEmu source that you are using ?

[Shadow-Wolf]

well im using the source from shawns cvs
http://shawn319.eqemulator.net/cvs/ no changes made to it except for the ones you said to add

[Tertiary]

Don't add the

#ifdef __MINGW32__
#include "../common/Portable_vsnprintf.h"
#define vsnprintf portable_vsnprintf
#endif

to common/types.h (or remove it if you did). That was an error that slipped in while I was reworking the changes and compiling the howto.

[Lurker_005]

Very nice job! Should make quite a few people happy.
Dang! that makes an F#$%ing HUGE zone.exe!

First a note, I updated to mingw 3.3.1


In world\console.cpp

if defined(WIN32) && !defined(__MINGW32__)

is missing the # on the if

I had to add -D_GLIBCPP_USE_C99 -D_GLIBCPP_USE_C99_DYNAMIC to the dev files.

I got

Warning c:\SourceCode\EQEmu-0.5.3-DR1\world\Warning
.drectve `%.*s' unrecognized

when compiling world


For perl support:
c:\dev-cpp\bin\reimp -d c:\perl\lib\core\perl58.lib

I didn't do any testing besides compiling it.


FYI The changes didn't have an effect on compiling in MSVC++6
Not that they should have.

Any developers using bloodshed want to join the dev team ?

[Muuss]

Well, nice job Tertiary, amazing !

I compiled without real trouble using your fixes, with dev-cpp 4.9.8.0. things i did :
--added Portable_vsnprintf.h/cpp to the project files
--changed -lzlib to -lzlib1 (i used the pre-compiled zlib1.dll from www.zlib.org)
--adapted the directories to my configuration

Thank you for porting eqemu to BloodShed, that's great of you, nice to have it compiling on a free w32 compiler !

ps : zone.exe weights 10

[Muuss]

zone.exe weights 10 718 428 bytes.

for zone.dev,
project -> project options -> compiler [tab] -> linker -> generate debugging information = yes

reduced zone.exe to 2

[Shadow-Wolf]

ok, i got eqmemshare.dll compiled nothing bad so far but when i try to compile world.exe i get these errors:

[dingo01]

For the first part of your problem, correct the typo that Lurker pointed out. In world\console.cpp, add a # to the front of

if defined(WIN32) && !defined(__MINGW32__)

For your second problem, the makefile is looking for zlib.dll in the C:\dev-cpp\lib folder, so make sure you have a copy of it over there and you should be alright.

I do have a problem of my own, though, that maybe someone could help with. Apparently I'm not installing or using reimp right. When I try to run World.exe or Boot5Zones, I get this error:

The procedure entry point mysql_real_escape_string could not be located in the dynamic link library libmysql.dll.

Is there a certain directory I should be in when I run the reimp and dlltools commands? Do I have to add any files anywhere else? I ran both of those commands as listed just from whatever directory I happened to be in. I installed MinGW 3.1.0-1 in the dev-cpp\bin folder (and also have an install sitting in dev-cpp\bin\MinGW and also have all the contents of MinGW\bin sitting in the bin directory). When I run those two commands it pops up a new command prompt without an error, like the command went through. Any help would be greatly appreciated.

Oh, and great package, Tertiary!

yay got it working now you rock tertiary!(and dingo01
for his bit of help)
