Wierd linking errors that I donnn't quite get yet.

[walkeraj]

I'm trying to compile an open source game called IVAN
[ivan.sourceforge.net], and I'm able to compile it from a makefile, but
not from an IDE. I have attempted to recreate the way the makefile
compiles the project as closely as possible, yet I'm getting odd
linking errors. I think I've traced it to some kind of problem with
the SDL libraries it uses, yet I can't explain why it will compile from
the makefile and not from the IDE. I have made sure that the ide knows
all of the include paths, and is linking to all of the libraries in the
makefile (and then some). Here is the makefile:

=======================================

As you can see there aren't any errors until linking, yet I cannot
identify where these errors are coming from. It LOOKS like some
library or another isn't being included, but no extra libraries are
listed in the makefile, which compiles just fine. You can even see
that I attempted to fix some of the errors by including libwinmm.a, but
that didn't solve all of them, and I've decided to ask for help rather
than attempting to include random libraries without any direction

 

[Jim Langston]

I'm trying to compile an open source game called IVAN
[ivan.sourceforge.net], and I'm able to compile it from a makefile, but
not from an IDE. I have attempted to recreate the way the makefile
compiles the project as closely as possible, yet I'm getting odd
linking errors. I think I've traced it to some kind of problem with
the SDL libraries it uses, yet I can't explain why it will compile from
the makefile and not from the IDE. I have made sure that the ide knows
all of the include paths, and is linking to all of the libraries in the
makefile (and then some). Here is the makefile:

I dont' see where you're linking to the directx libraries in your makefile.

 

[walkeraj]

Which libraries should I link? I don't think it's a problem with the
makefile.

If I run "mingw32-make -f ivanmgw.mak" from the command line, it works
fine. ivanmgw.mak is the makefile that I pasted in the message above,
and as you can see, it makes no mention of directx libraries. It seems
to be a problem with the way the SDL is being linked through the IDE.

Further, I've tried linking almost all of the directx libraries that
come with mingw to the project through the IDE and nothing works.

 

[walkeraj]

I think I've narrowed it down to a library dependancy issue during
linking. These are the libraries I'm linking. When they are linked in
this order:

...\..\MinGW\lib\libmingw32.a
...\..\MinGW\lib\libwinmm.a
...\..\MinGW\lib\libSDLmain.a
...\..\MinGW\lib\libSDL.a
FeLib\Release\libFeLib.a

The errors start like so:

...\..\MinGW\lib\libSDL.a(SDL_systimer.o): In function `SDL_StartTicks':
/home/hercules/public_cvs/SDL12/src/timer/SDL_systimer.c:73: undefined

although IID_ errors appear in both cases.

Can anyone help me???
