My Makefile for win32-gcc for a static lib creates a dll

Hi.
My engine is a static lib and my Makefile for win32-gcc creates a dll (that works!). Even though it works I don't want that dll so how can I make it only a static lib?

Makefile:

Code: Select all

VERSION = 0.1

# make
# This will compile NGE, create a static lib (libNGE.a), and copy it into the subdirectory lib/Linux. That's all.

# If you want NGE to be compiled as shared lib (libNGE.so.versionnumber), then run:
# make sharedlib
# make install

#List of object files
NGEOBJ = CConfigManager.o CursorController.o FontController.o Game.o GameEntity.o GameManager.o GameState.o GridSceneNode.o CIniFileReaderIrr.o CIniFileReaderStub.o CIrrKlangDevice.o CIrrKlangPlayedSound.o CIrrKlangSoundObj.o NGEReceiver.o NUSoftwareIntroSceneNode.o StateCredits.o StateIntro.o StateMenu.o StatePlay.o StateSettings.o IAudioDevice.o IConfigManager.o IIniFileReader.o nge.o NUS.o CLevelManager.o CEmptyLevelNode.o CRegionLevelNode.o CWorldLevelNode.o CZoneGroupLevelNode.o CZoneLevelNode.o Level.o NUSoftwareIntroLevel.o CNullAudioDevice.o CNullPlayedSound.o CNullSoundObj.o ISoundEmitterSceneNode.o ISoundListenerSceneNode.o CSceneNodeControllerAnimator.o IActor.o INPC.o IPlayer.o PlayerSpaceship.o IItemEntity.o

# Next variable is for additional scene nodes etc. of customized NGE versions
EXTRAOBJ =

LINKOBJ := $(NGEOBJ) $(EXTRAOBJ)

Thanks.

P.S
randomMesh created that Makefile.

there's never any command to create a static lib file.

where it says NGE_DLL:= ...
add an extra variable that += on the dll path, the file extension
so instead of

Code: Select all

NGE_DLL := ../bin/Win32-gcc/NGE.dll

use

Code: Select all

NGE_DLL := ../bin/Win32-gcc/NGE.
NGE_DLL_EXT = .dll
NGE_STA_EXT = "whatever"

and add this variable to the back of the correct compile spots
i guess...i'm not to familiar with windows makefile build systems

Well, since the makefile is just a rewrite of Irrlicht's, the usual 'make staticlib' should work.

I tried: mingw32-make NDEBUG=1 all_win32 staticlib
and I get:

Code: Select all

ar: creating libNGE.a
cp libNGE.a ../lib/Linux
process_begin: CreateProcess(NULL, cp libNGE.a ../lib/Linux, ...) failed.
make (e=2): The system cannot find the file specified.
mingw32-make: *** [staticlib] Error 2

C:\nge\source>

And I still get a dll AND a libNGE.a file.

@rooly: "and add this variable to the back of the correct compile spots" - and where is that exactly

And you mean this variable yes? NGE_STA_EXT.
And what about the `= "whatever" `?

Oh, I guess you should use staticlib_win32. Also use it as the only target after a clean. Also, your makefile environment should provide a cp command, as it is required for make.

Just to note, to get rid of the "cannot find the file specified", save this

Code: Select all

set cppatha1=%1
set cppathb1=%2

set cppatha2=%cppatha1:/=\%
set cppathb2=%cppathb1:/=\%

copy %cppatha2% %cppathb2%

as a bat file called "cp.bat" in the windows directory, to provide an equivalent to the unix cp command.

Thanks but I did this:

clean_tmp_files.bat

Code: Select all

del *.a /Q
del *.o /Q
del *.d /Q
del *.user /Q
del *.ncb /Q
del *.suo /Q

mingw32_build_debug.bat

Code: Select all

mingw32-make all_win32
del ..\bin\Win32-gcc\NGE.dll /Q
clean_tmp_files

mingw32_build_release.bat

Code: Select all

mingw32-make NDEBUG=1 all_win32
del ..\bin\Win32-gcc\NGE.dll /Q
clean_tmp_files

And I also realize why everything happens.
when I do all_win32 it makes the staticlib config as well as dynamic lib config. Now what hybrid suggested is to compile using only the static lib config (which is right). I just don't really care about it anymore and because maybe in the future I would make it also as a DLL I don't care letting it says this way.

But thanks anyways!

well, it was more for the benefit of anyone else who stumbled across this problem. I guessed you would have solved it by now

Cool, Thanks anyways!
