Talk:Build the Viewer on Linux

You need yacc too --Eddy Stryker

I had to add "class LLUICtrlFactory;" to llui/lluictrl.h and llui/llviewborder.h to avoid a bunch of problems about that class missing --Eddy Stryker

Isn't it nescessary to use scons with the option OPENSOURCE=no since the source tarball of 2007-01-12, if you wanna use the fast KDU image decoding libraries? I haven't tried thus I am not sure and didn't add it, but the following code block taken from the SConstruct file seems to indicate it:

	if opensource == 'yes':
		flags += '-DLL_USE_KDU=0 '
	else:
		flags += '-DLL_USE_KDU=1 '

llmozlib

As Tofu wrote (Feb 23 2007), "you shouldn't generally need to download and build LLMozLib for a SL viewer build unless you're hacking on LLMozLib itself or porting SL to a platform which we don't supply pre-built libraries for".

Nonetheless, there's a need of instructions on

• how to disable llmozlib in FL-1.13.3.58185 and FL-1.13.3.58390 as explained at a thread of SLDev@lists.secondlife.com
  • Add MOZLIB=no to your Scons build command when compiling the source

and/or

• how to compile those versions with the current llmozlib from ubrowser.com

I edited it so it's complete if you want llMozLib off, getting llMozlib compiled and working with the viewer is actually nontrivial, compiling llMozLib is just about as hard as compiling the viewer itself! Gigs Taggart 08:06, 27 February 2007 (PST)

What functionality is lost if you do not use llmozlib? Meyaden Beck 20:11, 12 April 2007 (PDT)

mozjs

A similar problem seems to be present with beta-1.13.4.3, only that it's -lmozjs not -lllmozlib that's failing at linktime. I can't even seem to locate the corresponding header file (expected filename 'mozjs.h') so it might well be that the problem only looks similar to the llmozlib one, but actually isn't. I'll post to the [sldev] list as soon as I have investigated this further. --Boroondas Gupte 11:22, 1 March 2007 (PST)

Help?

Would it be useful to add a blurb on where people can get help compiling, specifically in Linux. Or at least an internal link to another wiki page that has a list of places to get help in each version, MAC/WIN/LIN/BSD/(however far people want to break it down, etc.).

little helper script

For those of you who don't want to copy-paste from this article for every build they compile, I put a little bash script I'd liked to share in my user space: User:Boroondas_Gupte/unpack.sh. It just does a part of what's explained in this article. --Boroondas Gupte 09:59, 6 March 2007 (PST)

Error?

Under the heading "fix shell scripts" there is a header file listed. can someone else confirm this should not be in that list, and if it should, why does it not have a #!/bin/sh at the top of it?

Required Headers

Is there a reason that the instructions include copying header files to the source tree?

I have not attempted the install yet, that will probably be in a few days for me. However, most packages don't require the copying of header files from any standard lib into their own source directories. I am not sure if this practice is really a good one.

Will the package not compile if the headers are simply in their proper locations? If so, this is something that the developers may want to consider fixing. I would personally consider that a bug.

Normal procedure with most apps is to have the librarries propperly installed, and have the code or makefile written so that it looks in the right place. Meyaden Beck 19:41, 12 April 2007 (PDT) (I forgot to sign before I think)

Autoconf is a wonderful tool. :P

This setup is so that a fixed build of included libraries are setup for each branch and platform. The host platform can change independently of the SL build. Also, isolation of these libraries greatly reduce debug issues. There are a few patches to use the host platform's installed libraries instead. However, a few changes still need to be made for consistency. Dzonatas Sol 11:58, 12 April 2007 (PDT)

Hmmm... I see, I think. My next question (and if I get the time I may fix this one myself), why the choice to pretty much ignore compilation of llMozlib? Stating that "Compiling it is a pain, and this is how you disable it", doesn't look good. I haven't gotten that far in my current Linux install yet. I just finished installing XFce4, but as soon as I get OpenOffice.org and Blender installed, I will likely move on to Second Life. When I do, I will go through the steps of compiling llMozlib and take notes on what I did to make it work. :-) I should probablly also make sure to include a warning that I am using an LFS build. However, the instructions the LFS site uses to build most packages should theoretically work for just about any system. ^_^Meyaden Beck 19:41, 12 April 2007 (PDT)
