[solved]Compiling an Irrlicht program for "distribution"

[Nyx Erebos]

Hello there,

usually I can find quite easily solutions to any Irrlicht related problem so for my first post it'll not be an (fully) Irrlicht related question.

I've made an Irrlicht program (navmeshes with A*) using opengl as renderer and pthreads, and now that I've finally got it to work I want to try to give it to a friend. So my question is basically how do I do that ? I want to compile my program and give it to him without him having to install anything. I've tried numerous things to get it to work but with no success (I've been messing around with libIrrlicht.a libIrrlicht.so and so on for two days). If there's a tutorial out there on how to do it on linux (ubuntu) that would be great or if you could give me the steps to follow I'd give you an internet hug (a tuto on how to do it on windows would be awesome too).

Thanks for your help and pardon my english, I'm french .

If your dependencies are not too complex you could instruct your friend to just install the needed libraries via his package manager, like

Code: Select all

sudo apt-get install irrlicht <additional deps here>

Other than that, try to link everything as statically as possible (-> use the .a instead of the .so), copy any left runtime deps into the folder with the binary and include that folder in the lib path. Use your favorite search engine for further info or feel free to ask here.

Cheers!

Thanks for the quick answers .

I've already tried that and several variations.

Actually I want to avoid that.

I'm trying hard but can't get it to work . Here's my makefile (don't mind the windows parts) :

Code: Select all

CXXFLAGS = -Wall -O3 -ffast-math -std=c++0x -g
 
ifeq ($(HOSTTYPE), x86_64)
LIBSELECT=64
endif

DESTPATH = ./$(Target)$(SUF)

    $(warning Building...)
    $(CXX) $(CPPFLAGS) $(CXXFLAGS) $^ -o $(DESTPATH) $(LDFLAGS)
 
clean: clean_linux clean_win32
    $(warning Cleaning...)
    @$(RM) $(OBJ)
 
clean_linux clean_win32:
    @$(RM) $(DESTPATH)
 
.PHONY: all all_win32 clean clean_linux clean_win32

I don't know if all the libs dependancies are necessary but even when I remove them I've got the same errors. I have the libIrrlicht.a and pthread.a in ./Linux and the headers in ./include/Irrlicht and ./include/pthread. What do you mean by runtime deps ?

After compiling my program it works on the computer where I developped it but when I try to launch it from Virtualbox on another computer (yeah I know it's maybe not the best way to test it but I don't want to install another linux just to be sure that the program doesn't get the lib from usr/lib) I get this :

Code: Select all

$./Demo
./Demo: error while loading shared library: libIrrlicht.so.1.7a: cannot open shared object file: No such file or directory

When I type ldd Demo :

Code: Select all

    linux-gate.so.1 =>  (0xb77b7000)
    libIrrlicht.so.1.7a => not found
    libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xb7788000)
    libstdc++.so.6 => /usr/lib/i386-linux-gnu/libstdc++.so.6 (0xb769e000)
    libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xb765b000)
    libgcc_s.so.1 => /lib/i386-linux-gnu/libgcc_s.so.1 (0xb763e000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb748b000)
    /lib/ld-linux.so.2 (0xb77b8000)

It doesn't find libIrrlicht.so.1.7a and the pthread lib is linked from lib/i386-linux-gnu/. I think there's something I don't understand about compiling (and I promise I searched, a lot ).

I feel a bit stupid now, I thought it was an Irrlicht setup related problem but no it was really just a compiling knowledge fail. I just had to find out that it was not a good idea to try to link staticly opengl and pthread, ant to use the options -static and -dynamic. Thanks for your help anyway
