Hi!

I want to compile the following code:

SuperStrict

Framework BRL.Blitz
Import Pub.OpenAL

On Ubuntu the result is:

dlopen and dlsym are the equivalent to Windows LoadLibrary and GetProcAddress and defined in dlfcn.h .

So how can I link dlopen and dlsym to my execute?
(btw. have BMax an own linker or use it from GCC/Flatassembler?)

Do you have the OpenAL-Development Libraries installed?

No, and this is not necessary for this problem(or?). Becouse, the OpenAL library is loaded at runtime and so the library is not needed by compiling/linking the program.

You'll need it to link to the shared library.

It uses the GCC linker.

You need to install the OpenAL libraries.

You need to :

Import "-ldl"

Many thanks Brucey!!!
I've testet it with Import "libdl.a" or "libdl.so" but all doesn't work. (libdl.so can't import and libdl.a can't statically linked)

So for the future - how do you know that "-ldl" is needed? What can be linked with Import(outside of *.bmx, *.c, *.a, *.cpp)?

Experience ;-)

In reality, the -l is passed to the linker as you would when using it on the command line. So, for a library called libfish.so, you take of the prefix "lib", and the suffix ".so", leaving you "fish". You would then import with "-lfish".

Ahh, ok, thank you :)
