Statically linking

azer_tyuiop · November 30, 2010, 5:45pm

Hi everyone,

I work on Linux and use SDL and SDL_image. I have sdl on my machine, but I want
to lunch my program via ssh on dedicated calculus machines of the lab. And they
don’t have and don’t want to install sdl.

So I thought at linking statically sdl. I replaced this :
sdl-config --cflags --libs -lSDL_image
by this, in my makefile :
-Wl,-Bstatic -lSDL_image sdl-config --static-libs -Wl,-Bdynamic

But it do not want to compile anymore (unreferenced functions of SDL).

Is it wrong?

Also any other way of making the program work without needing to install libSDL
are welcome.

Thx

Post the undefined references, please.–

I think it is to all calls of sdl functions. Here are all the errors I get at
building, thx in advance :

I did, it change nothing. Maybe it can be helpful so here is my makefile. Note
that by uncommenting/commenting the two successive lines LDFLAGS (to make the
lin dynamic) it compile just fine.

Apart the static linking, Is there any other way to make my program run on a
machine that don’t have sdl?

thx

If it is the same architecture, you could ldd' your executable, copy all dynamic libraries listed not expected to be in the other system and pack them together. Maybe even better is to issue a ldd’ on the other
machine to know which ones are missing.

Yes same architecture.

Ok, I did an ldd on the target machine, and I got a not found on the
libSDL_image library (and only on this one, the others are ok). However, I
already tried in the past to copy the libSDL_image in a personal folder, and
exported a variable to tell the linker to search for the library in that rep. I
didn’t got the libSDL_image not found error, however I got an internal error
from SDL, saying that it was not able to initiate the framebuffer /dev/fb0, or
something like that. I am not sure, but I think it is a right issue, as if I
remember well, Linux give the same rights as of the owner of the lib. And so,
this solution cannot work, as the lib have to be in /usr/lib. I am not sure of
what I am saying but that’s how I interpreted the error.

So copying the .so seems not to be a solution.

However thank you so much for your help. It is the very welcome. I really can’t
figure how to solve this.________________________________

Instead of linking statically, you could use the linker’s -rpath flag to
tell it to look for dynamic libraries in another location. A typical
compile line might have this appended:
-Wl,-rpath,$ORIGIN
You would double the $ to put it in a Makefile.

Then, just ship the shared object files alongside the executable.

No. On Linux, dynamic libraries get the same credentials as the rest
of the process.

Well ok. So I tried again, I put the libSDL_Image in my rep. I than do :
LD_LIBRARY_PATH=/users/tao/aze/libsdl:$LD_LIBRARY_PATH, and than I lunch the
program. I do not get anymore

error while loading shared libraries: libSDL_image-1.2.so.0: cannot open shared
object file: No such file or directory

The programs starts, and than I do this error :

     (c) 2001-2008  The world wide DirectFB Open Source Community
     (c) 2000-2004  Convergence (integrated media) GmbH----------------------------------------------------------------

(!) DirectFB/FBDev: Use 'fbdev' option or set FRAMEBUFFER environment variable.
(!) DirectFB/Core: Could not initialize 'system_core' core!
 --> Initialization error!
[critical] cannot initialize SDL.

-----------

But I solved partially my problem. There is a batch mode in my program that do 
not call any graphical routine. It is the one I use when I lunch experiments on 
other machines. So by shipping the .so with it, I can lunch in this mode. Which 
is a big thing and is all what I need. However if it solves my problem, it do 
not solve 'the' problem, how to lunch sdl apps on machines that cannot have root 
access to install libSDL?

And when I add -lpulse, or -lpulse-simple, it do not find it.

But I checked and I do have libpulse ad libpulse-simple in /usr/lib. What can I

The errors I exhibited at the end was before I link with ljpeg. It works fine
after. The only remaining problem seems to be pulse-audio.

As for the distribution, I have ubuntu 10.04 on my machine, and I can ask the
admin to install any package on it. So if the static version of pulse audio is
available on the repositories, it should be no prolem to install.

I will try this tomorrow and also try your modified LDFLAGS.
