Re: [osg-users] problem with osg 2.4 stable release
I must admit, due to both my own and others struggles getting DLLs properly locationed, I've been very tempted to build as many 3rdParty libs as possible in only static configuration. That minimizes the runtime dependency chain, so we'd only have to deal with OSG finding its own DLLs. I dont recall now many of the upstream 3rdParty support a static config (I'm not going to add one if they dont supply it themselves) but I'll be looking in this direction in the future. -- mew On Wed, Jun 18, 2008 at 10:18 AM, Robert Osfield [EMAIL PROTECTED] wrote: Hi Guys, I don't have much experience to through into discussions about static vs dynamic libs under Windows, but what is clear from sitting on the list how much traffic is dedicated to build issues under Windows, almost all relate to dll's problems. With the OSG-2.x we've tried to tackle this with the version'd dll's and version plugins directories which should help, but it hasn't solved it completely - users are still have lots and lots of problems. Using static linking by default for the OSG plugins does seem like a good way of tackling a big part of problem, and while there will be a memory overhead I'd say it's well worth it. If less users have problems then their experience of OSG under Windows will be more positive and we'll have less support for wade through. Watching these threads as an outsider it does seem like keeping Windows is a black art, with a complex matrix of things that work in different combinations. Personally I'd much rather programmers spend their brain power on doing 3D graphics apps than fighting build systems/dll's etc learning all the caveats of working on specific platforms. So if you want to go static link of external dependencies under Windows then guys, you have my backing.

Bonjour Arnaud, I put the libpng13.dll in the same directory of osgdb_png.dll but in visual studio output window the dll is called anytime I try to read a png and then unloaded after the operation. No, libpng13.dll should be in your PATH or in your executable's directory. The plugins are in OSG_BIN_DIR\osgPlugins-version, which is not on your PATH (and should not be) - OSG loads them directly which is why it works, but the libpng13.dll needs to be on the DLL search path. It's up to you where you want to put it. I usually put it alongside osgNN-osg.dll (in my case my OSG_BIN_PATH is on my PATH). If you include the OSG DLLs alongside your application in an installer, for example, you should include libpng13.dll alongside the OSG DLLs (not the plugins).

Hi Paul, Yes, the increase in size would be a downside. But disk space and memory are fairly cheap these days. I suspect only a small number of plugins would increase (jpg, png, tiff, jp2). I think we need to quantify it. Then we can evaluate if it's significant or not.

Perhaps linking to static dependencies could be an option in the CMake generation process, with the deps binary packages including static libs, and the default being static.

Hi Paul, I wasn't suggesting that _apps_ link statically, merely that the plugin DLLs link statically against their (non-OSG) dependencies. Ah, I hadn't seen it that way. It would in that case increase the size of plugins that use the same dependencies (zlib is used by multiple plugins I think), and the thing with multiple OSG versions using more space would remain. But it would be much better than linking apps statically. Well, it was more of a philosophical question, but a poll would be interesting. Using the ML for that will be horrible, although easy to do.

For OS/X there are no prebuilt packages, right? Would voting for multiple selections be allowed? I use OSG on Win32 and Linux for instance...

But disk space and memory are fairly cheap these days. I suspect only a small number of plugins would increase (jpg, png, tiff, jp2). I think we need to quantify it. Then we can evaluate if it's significant or not. If I have 16 OSG apps which all include (for example, I didn't try it) 5MB of dependencies statically linked each, that's 80MB instead of 5 (for the DLLs which could be shared). However, if I need to link to a specific version of OSG+deps, I'd need my application to include the specific DLLs in its directory anyways, so no savings there... I wasn't suggesting that _apps_ link statically, merely that the plugin DLLs link statically against their (non-OSG) dependencies. Perhaps linking to static dependencies could be an option in the CMake generation process, with the deps binary packages including static libs, and the default being static. Then if others want to compile and link to DLLs, they can switch the option in OSG's CMake config. Here I am suggesting ideas which I don't have time to implement... Shame on me. Spoken like a true open source contributor :) It would be interesting to know which users specifically are having problems: 1. using prebuilt OSG + dependencies (either Mike's deps or perhaps from the gnuwin32 project), not compiling their own app, are merely trying out the OSG 2. using prebuilt OSG + dependencies, are compiling their own app 3. using prebuilt dependencies, compiling OSG from source, compiling their own apps 4. compiling everything from source Are you suggesting a poll? Doing this on the mailing list would be a bit hard to keep track of... (Incidentally, I'm mostly in 3, though I'll have to move to 4 for 64 bit soon). Does the wiki have a poll functionality? Or perhaps we could use Gordon's forum for that? Well, it was more of a philosophical question, but a poll would be interesting. Using the ML for that will be horrible, although easy to do. I don't think trac supports polls out of the box. If we could have a web-based poll on the forum site we'd only have to publicize it on osg-users.

thanks a lot J-S the problem was that the libpng13.dll was not in the path. I thought that only osgdb_png.dll was needed i owe you one ;) Date: Wed, 4 Jun 2008 09:02:07 -0400 From: [EMAIL PROTECTED] To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] problem with osg 2.4 stable release Hello David, i have a osgdb_png.dll file which is the result of the compilation and i can see in the visual studio ouput window that the dll is called anytime i try to read a png and then unloaded after the operation The PNG plugin, like some others, has a dependency on an external DLL, namely libpng13.dll in this case. Can you check if you have this in your path? You can find it in the 3rdparty/bin directory. Put it in your OSG/bin directory if you don't already have it. (or somewhere else where you know your app will find it before any other DLL of the same name) Additionally, you can try to set OSG_NOTIFY_LEVEL to DEBUG to see if there are other problems. If, for example, the debug output shows that the osgdb_png.dll plugin is loaded, then it finds your PNG file and tries to open it and fails, it's most probably because either it can't find the libpng13.dll, or because it's finding the wrong one (as happened to me lately). Make sure in that case that the OSG bin directory is early in your PATH or in the search path for DLLs, before any other directory that may contain another copy of libpng13.dll.

Hi David, It'd be useful if you to say what platform you are using/how you built the OSG + dependencies, and clarify the problem with loading files. As the texture no longer having the image, is this after loading? After rendering? Do you have Texture::setUnrefImageAfterApply(bool) enabled? Robert.

Re: [osg-users] problem with osg 2.4 stable release
Hi David, Have a search through the recent achives w.r.t png plugin. The png plugin doesn't have any code changes to between 2.2 and 2.4 so it must be just a build issue/dependency isse. W.r.t getImage, my guess is that your paged database has unref on apply enabled, and a bug fix since 2.2 has meant that this feature is now working correctly, if you don't want this feature then you'll need to disable it in the external files or via a Registry::ReadFileCallback.
