Development Environment for Multiple Viewers
Development Environment for Multiple Viewers
Highlights:
- Productivity increase (automation of repetitive tasks)
- Complete directory structure proposal
- Directory Dependent History and Environment Switching
- Support for development of multiple viewers on one host
- quilt
- ctags
Directory structure
The ROOT
Choose a directory that will contains everything related to SecondLife, OpenSim etc. In my case this directory contains (currently) 12 GB of data, so pick a place with space ;).
For the sake of copying and pasting commands, lets use an environment variable for this 'root' directory.
export ROOT=/usr/src/secondlife
I use /usr/src/secondlife
, but you could of course use something else, like
/opt/secondlife
, or $HOME/SLroot
or whatever.
$ROOT/viewers
The root directory will contain a subdirectory viewers
.
mkdir $ROOT/viewers
viewers
will contain any data related to viewer development (viewer build system
configuration, patches, viewer source trees, viewer subprocesses (ie SLVoice), User Application Directories (AppDir),
documentation...) while $ROOT
itself will contain everything else (things that are less close to developing the viewers,
like special/patched/custom libraries, custom scripts, uploaded assets (textures, sounds, animations), snapshots, third party projects related to SecondLife etc etc).
Purely as a suggestion, you could do
mkdir $ROOT/blender $ROOT/gimp $ROOT/libomv $ROOT/textures $ROOT/wav $ROOT/Snapshots
Viewer project base
Each viewer (version) needs it's own directory, not just for the source tree, but also for meta data (patches, quilt cache, build system configuration, etc). The below deals with a single viewer version, but you can repeat it for multiple viewers. For the sake of easy copy and pasting, lets give our first viewer version an environment variable too. For example,
export VIEWERNAME=snowglobe-1.x-svn
Then, for each such viewer create the following directories:
cd $ROOT/viewers mkdir $VIEWERNAME cd $VIEWERNAME mkdir timestamps mkdir quilt mkdir quilt/patches mkdir quilt/pc
The real source tree (the one containing the indra directory) should be called 'linden' and also goes here. For example,
svn checkout https://svn.secondlife.com/svn/linden/projects/2009/snowglobe/trunk linden
Directory dependent history and environment
Now to automate everything! First install cdeh.
Also set DEFAULTPATH
in your .bashrc
. For example,
export DEFAULTPATH="$HOME/bin:/usr/local/bin:/bin:/usr/bin:/sbin:/usr/sbin" # Or whatever your current PATH is! export PATH="$DEFAULTPATH"
Obvious, DEFAULTPATH may not depend on PATH.
If you intended to use cdeh also for library projects (ie, libraries in $ROOT) and you have multiple
compilers installed (ie, you use a special compiler version for the viewer) then you also should set
DEFAULT_TOPPROJECT
in your .bashrc
. Set it to $ROOT/viewers, but expand $ROOT (type it out fully) because obviously ROOT is not set at the moment you log in.
Here it might be wise to reboot, so that every login shell has DEFAULTPATH set; or otherwise make sure to source .bashrc to set it until you have time to reboot. The effect of not having it set is getting an empty PATH so that you will have to type full paths to execute anything :p
Next install this file in the root (/) of your operating system,
world readable, and rename it to /env.source
. Yes, that is the real root, not $ROOT.
Congratulations! You now have directory dependend history and environment switching! Lets start with creating a separate history file for most of the core directories:
cd $ROOT addhistory cd viewers addhistory cd $VIEWERNAME addhistory cd linden addhistory
As you can see I just love to have a different command history for every directory :)
Next we have to add a few environments. Copy and paste the following code blocks.
cd $ROOT/viewers cat << EOF > env.compiler CC="gcc" CXX="ccache g++" export CC CXX EOF
echo "export TOPPROJECT=$ROOT" > env.viewers cat << EOF >> env.viewers source /env.source source $TOPPROJECT/env.compiler INSTALL_PREFIX="/sl" LDFLAGS+=" -L$INSTALL_PREFIX/lib -L$INSTALL_PREFIX/usr/lib" PKG_CONFIG_PATH="$INSTALL_PREFIX/lib/pkgconfig" pre_path "$INSTALL_PREFIX/bin" pre_path "$INSTALL_PREFIX/lib" LD_LIBRARY_PATH export PKG_CONFIG_PATH LD_LIBRARY_PATH # Use libcwd #CXXFLAGS+=" $(pkg-config --cflags libcwd_r)" #LDFLAGS+=" $(pkg-config --libs libcwd_r | sed -e 's/ *$//')" # Use custom libllqtwebkit #CXXFLAGS+=" -I/usr/src/secondlife/llqtwebkit/install/include" #LDFLAGS+=" -L/usr/src/secondlife/llqtwebkit/install/lib" # Use the patched (CVS) version of gstreamer installed in /sl: #LDFLAGS+=" -L/sl/lib" #CFLAGS+="-g3 -I/sl/include/gstreamer-0.10" #CXXFLAGS+=" -g3 -I/sl/include/gstreamer-0.10" #export GTS_PLUGIN_PATH="/sl/lib" REPOBASE="$PROJECTBASE/linden" INDRA="$REPOBASE/indra" alias vi='vim -c "set tags=$INDRA/$BUILDDIR/tags" -c "set tabstop=4"' alias s='/bin/ls $INDRA/ll*/*.{cpp,h} $INDRA/linux_crash_logger/*.{cpp,h} $INDRA/lscript/*/*.{cpp,h} $INDRA/newview/*.{cpp,h} $INDRA/media_plugins/*/*.{cpp,h}' alias grep='grep -Hn' alias configure='make configure' QUILT_PATCHES="$PROJECTBASE/quilt/patches" QUILT_PATCHES_PREFIX=1 QUILT_DIFF_OPTS="-p" CCACHE_DIR=/ramdisk/ccache export QUILT_PATCHES QUILT_PATCHES_PREFIX QUILT_DIFF_OPTS CCACHE_DIR function make () { CURDIR=$(pwd) cd $INDRA case $@ in configure) rm -f $BUILDDIR/CMakeCache.txt ./develop.py $CONFIGURE_OPTS configure $CMAKE_DEFS -DCMAKE_CXX_FLAGS:STRING="$CXXFLAGS" -DCMAKE_EXE_LINKER_FLAGS:STRING="$LDFLAGS" cd $BUILDDIR/newview && (\ ln -sf ../llplugin/slplugin/SLPlugin; \ mkdir -p llplugin; \ ln -sf ../../media_plugins/webkit/libmedia_plugin_webkit.so llplugin/libmedia_plugin_webkit.so; \ ln -sf ../../media_plugins/gstreamer010/libmedia_plugin_gstreamer010.so llplugin/libmedia_plugin_gstreamer.so; \ ln -sf $INDRA/newview/app_settings; \ ln -sf $INDRA/newview/skins; \ ln -sf $INDRA/newview/character; \ ln -sf $INDRA/newview/res-sdl; \ ln -sf $INDRA/newview/gpu_table.txt; \ ln -sf $INDRA/newview/featuretable_linux.txt; \ ln -sf $INDRA/newview/linux_tools/register_secondlifeprotocol.sh; \ ln -sf $INDRA/newview/linux_tools/launch_url.sh; \ ln -sf $INDRA/newview/linux_tools/handle_secondlifeprotocol.sh; \ ln -sf $INDRA/newview/secondlife-i686.supp; \ ln -sf $INDRA/newview/res/snowglobe_icon.png; \ ln -sf $REPOBASE/../../gdbinit .gdbinit; \ ln -sf $TOPPROJECT/SLVoice; \ cd app_settings; \ ln -sf $REPOBASE/scripts/messages/message_template.msg; \ ln -sf $REPOBASE/etc/message.xml; \ cd ../skins/default/xui/en-us; \ ln -sf mime_types_linux.xml mime_types.xml; ) ;; "") ./develop.py $CONFIGURE_OPTS build ;; clean|realclean) rm -rf $BUILDDIR/* #./develop.py $CONFIGURE_OPTS clean ;; ctags|tags) ctags -f $BUILDDIR/tags `s` ;; *) echo "Don't know how to make $@" ;; esac cd $CURDIR } function store_timestamps () { CURDIR=$(pwd); cd $REPOBASE; for f in `find . -name '*.h' -o -name '*.cpp' -o -name '*.cc' -o -name CMakeLists.txt -o -name '*.cmake'`; do mkdir -p `dirname $PROJECTBASE/timestamps/$f`; md5sum $f > $PROJECTBASE/timestamps/$f; touch -r $f $PROJECTBASE/timestamps/$f; done cd $CURDIR; } function restore_timestamps () { CURDIR=$(pwd); cd $REPOBASE; for f in `find . -name '*.h' -o -name '*.cpp' -o -name '*.cc' -o -name CMakeLists.txt -o -name '*.cmake'`; do if test "`cat $PROJECTBASE/timestamps/$f`" = "`md5sum $f`"; then touch -r $PROJECTBASE/timestamps/$f $f; fi done cd $CURDIR; } function quilt () { case $@ in refresh) /usr/bin/quilt refresh -p0 ;; *) /usr/bin/quilt "$@"; ;; esac } function svn () { case $@ in update) if /usr/bin/quilt top; then echo "Storing timestamps..." store_timestamps; echo "Merging update..." /usr/bin/quilt diff -p0 -z > current.$$.diff && \ patch -p0 -R < current.$$.diff && \ TOP=`/usr/bin/quilt top` && \ /usr/bin/quilt pop -aR && \ /usr/bin/svn update && \ /usr/bin/quilt push "$TOP" && \ patch -p0 < current.$$.diff && \ rm current.$$.diff; echo "Restoring timestamps..." restore_timestamps; else /usr/bin/svn update fi ;; diff) if /usr/bin/quilt top 2>/dev/null; then /usr/bin/quilt diff -p0 -z; echo "Patch relative from 'tag' \"$(basename `/usr/bin/quilt top`)\"." else /usr/bin/svn diff; fi ;; commit) echo "You're not supposed to do a commit in here!" ;; *) /usr/bin/svn "$@"; ;; esac }
