Hello,


Configuring and installing SDL 2 will interfere in some way with SDL 1.2?

Any news or update on this?

thank you very much

Nope. They changed the name of the library to "sdl2" from "sdl" when they broke the interface. I was busy with other projects lately. What's missing is most of the code that deals with windows and events.

Anyone has a recent dlopen/dlsym implementation? I found one from OS4Depot, by Chris Young. Unfortunately it doesn't work out-of-the-box for SDL2. Looks like OS4 ships with another version of libdl.so (it has different symbols than Chris').

Static libraries and shared object are mutually exclusive. Just remove the static lib, and link with something like:
-use-dynld -Wl,-rpath-link,/sobjs -L/sobjs

Unfortunately that doesn't help me to build SDL2 with dynapi support. I found some of my older SDK has dlfcn.h by Hyperion, I wonder was it dropped from the latest SDKs or did I lose it myself.

Regarding dynapi, here is some good info https://plus.google.com/+RyanGordon/posts/TB8UfnDYu4U

Of course we can implement a symbol loader by Elf.library, or just disable dynapi, but this looks like a possibility in a world full of statically-linking developers ;)

They dropped libdl.so in the latest SDK? I'm still stuck in the u6 era, so I didn't know about this. I think it's safe to disable the SObj loader for the time being, since almost nobody uses those SDL functions, and/or has fallback to libdl.

libdl is part of the SDK and it was updated also on the latest one. Which file is missing?

The header file (dlfcn.h) is missing or at least I can't find it in my SDK install.

dlopen/dlsym are not a file. they are functions part of dlfcn.h. I remember it was part of libdl updates but in case you need it you can download the file here:

That must be a really old version of the file because it's missing stuff that's already in the version 53.1 header.

The latest version of libdl.so is 53.4 (9.4.2013).

Thanks for confirmation. If you think libdl.so should be officially supported by the SDK, I can make a BZ entry, if needed.

Please do.

The soft link for the libdl.so file is still there so likely the header file was left out by mistake.

Done. Hopefully we get a new SDK this year :) By the way, should there also be a static libdl.a?

I'm using dlfcn.h from the older SDK for now.

No, it's just built as a shared object.

Configure doesn't work with 5.3.0

Seems to works with 4.9.1 as suggested by Capehill

You're probably compiling with newlib.

Have you tried adding -mcrt=clib2 to your compiler CFLAGS?
