Title: Compiling Sdl
Post by: merli on December 29, 2005, 07:00:17 am

Hello

I try to compile SDL on Zaurus using devimg. Everything seems to be OK except when I try to compile actual application I get foloowing messages

I need libSDLmain.a, libSDL.la, libSDL.a to compile application.

Can someone point me to right direction? What am I doing wrong?
Thank you very much

Hi

One of those "I don't quite understand the question" answers really.

The packages of the SDL libraries you require are [a href=\"http://ssel.vub.ac.be/Members/DennisWagelaar/download/zaurus/]Downloadable Here[/url]
Why re-invent the wheel by trying to compile them yourself.

The packages do not contain the static versions of the library but why you would want to link statically to the SDL libraries on a Zaurus?  Huge waste of limited space.

Amending the makefile of whatever you are trying to build to include in the LIBS =   -lSDL -lSDL_mixer -lSDL_image etc and removing the references to libSDL.a etc should allow a dynamic linking build.

If you really must have static libraries, I have found it easier in the past to compile them from the sources on my main computer which has the arm-linux-xxxx toolset installed and just specify to configure that I want to compile to target arm  (  ./configure --target=arm  or similar, run ./configure --help | less to get the configure options up )

Hope that is some help.

Hi

I have done some research into SDL and now see why you need to link libSDLmain.a to get a correct main() entry point for your program.

So I have tried to be of more practical use to you

I have cross compiled SDL-1.2.9 for arm with QTopia support enabled.

A package of the SDL libraries you require included  libSDLmain.a are [a href=\"http://myweb.tiscali.co.uk/drahthaar/Z/libSDL-1.2.9-arm-libs.tar.gz]Downloadable Here[/url]

I can bore you with the cross compile environment settings which allow the libraries to build at some later time if you wish.

Hope that is some help.

Thank you for your help. I have meantime switched to pdaXrom where everything "just" works. When I return back to Cacko I will try your SDL package. I tried to compile SDL 1.2.9 with Qtiopia support directly on Zaurus with zgcc or devimg package (no crosscompiling) but result library didnt work for me. I dont know what I did wrong.

Still I dont know how it is compiled for example snex9x which has SDL compiled dynamically as seen with ldd.

Thank you for making this available, could you please indicate where the different files have to be place in order to compile apps which require them? Can they just be place in any of the "lib" folders?

Sorry, haven't checked this forum for ages.

If you have not already found out -

The shared libraries need to be in whatever path is searched for libraries under your setup or specified in the makefile eg
(In Makefile)
LIBS   =   $(SUBLIBS) -L$(QTDIR)/lib -lqpe -ljpeg -lqte

so place libSDL_mixer.so in $(QTDIR)/lib and amend the line to

LIBS   =   $(SUBLIBS) -L$(QTDIR)/lib -lqpe -ljpeg -lqte -lSDL_mixer  or whatever is required.

If you want to include a static library such as libSDLmain.a I have always found it easier to copy it to the same directory you are building from and modify the Makefile line to

LIBS   =   $(SUBLIBS) -L$(QTDIR)/lib -lqpe -ljpeg -lqte -lSDL_mixer ./libSDLmain.a

regards
