Instructions for Setting Up DXR
Revision as of 21:25, 11 February 2009 by David.humphrey (talk | contribs)
This page describes the steps necessary to manually create a working DXR. The goal of this is to eventually be able to automate the process as part of an RPM for Fedora.
- mkdir ~/dxr
- mkdir ~/dxr/tools
- Setup a working Mozilla build environment:
- su -c "yum groupinstall 'Development Tools' 'Development Libraries' 'GNOME Software Development'"
- su -c "yum install mercurial autoconf213"
- Setup a working GCC+plugins build environment
- su -c "yum install mpfr-devel"
- Get Mozilla source code (needed for indexing, but also for SpiderMonkey)
- mkdir ~/dxr/mozilla-central
- cd ~/dxr/mozilla-central
- hg clone http://hg.mozilla.org/mozilla-central/ mozilla
- Build SpiderMonkey
- cd ~/dxr/tools
- link or copy js/ from the mozilla-central tree (cp -R ~/dxr/mozilla-central/mozilla/js/ ./js)
- cd ~/dxr/tools/js/src
- autoconf-2.13
- mkdir build-release
- cd build-release
- ../configure --prefix=~/dxr/tools/SpiderMonkey
- make
- cd ..
- Build GCC 4.3.0 with Plugin Support
- mkdir ~/dxr/tools/gcc-dehydra
- cd ~/dxr/tools/gcc-dehydra
- Obtain GCC 4.3 sources - wget ftp://ftp.nluug.nl/mirror/languages/gcc/releases/gcc-4.3.0/gcc-4.3.0.tar.bz2
- tar jxvf gcc-4.3.0.tar.bz2
- cd gcc-4.3.0/
- hg init .
- hg clone http://hg.mozilla.org/users/tglek_mozilla.com/gcc-moz-plugin-mq .hg/patches
- (for file in `cat .hg/patches/series`; do cat .hg/patches/$file; done) |patch -p1
- cd ..
- mkdir gcc-build
- cd gcc-build
- build for proper arch:
- (32 bit) ../gcc-4.3.0/configure --without-libstdcxx --enable-checking --disable-bootstrap CFLAGS="-g3 -O0" --enable-languages=c,c++ --enable-__cxa_atexit --prefix=$PWD/../installed
- (x86_64) ../gcc-4.3.0/configure --without-libstdcxx --enable-checking --disable-bootstrap CFLAGS="-g3 -O0 -m64" --enable-languages=c,c++ --disable-multilib --enable-__cxa_atexit --prefix=$PWD/../installed
- make
- make install
- cd .. (note: ./installed now contains the built gcc)
- Build Dehydra
- hg clone http://hg.mozilla.org/users/tglek_mozilla.com/dehydra-gcc/
- cd dehydra-gcc
- ./configure --js-libs=/home/dave/dxr/tools/SpiderMonkey/lib --js-headers=/home/dave/dxr/tools/SpiderMonkey/include --js-name=mozjs
- make
NOTE: running make check causes a known failure that can be ignored for now:
