Fork of https://github.com/mzhaom/lrte
- still using Google's GCC 4.9.2 branch and Clang 4.0 dev branches
- clang includes openmp and polly
- added a build of Intel's [https://github.com/ispc/ispc/][ispc] : Work In progress
install precompiled lrtev2 package. On production machine, lrtev2-runtime is all you need. Debug symbols, includes, etc are all optional
to install crosstools v2 on debian :
sudo dpkg -i output/lrte/results/debs/lrtev2-runtime*.deb
sudo dpkg -i output/lrte/results/debs/lrtev2-crosstoolv2-gcc-4.9*.deb
sudo dpkg -i output/lrte/results/debs/lrtev2-crosstoolv2-clang-4.0*.deb
sudo dpkg -i output/lrte/results/debs/lrtev2-crosstoolv2-ispc-1.9.2dev*.deb
the same thing can indeed be done with RPMs
I build all of this with a GCE VM using debian:jessie docker images. ubuntu:14.04 should work as well. and may have more reliable APT mirrors.
Install LRTE
git clone https://github.com/alichnewsky/lrte.git
cd lrte
TAR_DIR=upstream ./grte/downloads.sh
./release.py --no_build_crosstool --email [email protected] --docker_image=debian:jessie
Download gcc, clang and ispc crosstool source code
bash crosstool/get-gcc-svn.sh
bash crosstool/get-clang-svn.sh
bash crosstool/get-ispc-from-github.sh
Build and install crosstools
./release.py --no_build_lrte --email [email protected] --docker_image=debian:jessie
Only building ispc when lrte, gcc and clang crosstools have already been built
./release.py --no_build_lrte --crosstool_skip gcc clang --email [email protected] --docker_image=debian:jessie
AFAIK releases still have to be created manually from the github website I could not get them created programmatically
Assuming you have an un-encrypted .netrc, and that release v2.2_0 has been created in github, and that you have installed github-release tool(https://github.com/aktau/github-release) in you rpath:
export GITHUB_USER=username GITHUB_TOKEN=$(cat ~/.netrc |egrep "^password" | awk '{print $2}' | uniq) RELEASE_TAG=v2.2_0
bash upload-github-release.sh $(find output/lrte/results/ -type f)
It's recommended to just install the precomiled packages from release page. For example, to install lrtev2 with crosstool v2:
apt-get update
apt-get install -y apt-transport-https
echo 'deb https://github.com/mzhaom/lrte/releases/download/v2.0_0 ./' >> /etc/apt/sources.list
apt-get update
apt-get install -y --force-yes lrtev2-crosstoolv2-gcc-4.9 lrtev2-crosstoolv2-clang-3.7
On the production machines, you should need to install
lrtev2-runtime package, which contains the glibc and libstdc++
libraries.
Then gcc and clang under /usr/crosstool/v2/gcc-4.9.2-lrtev2/x86/bin can be used to produce binaries that only work with LRTE, which means these binaries only depend on glibc and libstdc++ coming from LRTE runtime, so they can be shipped without worrying about the system's glibc version.
Btw: the gcc and clang inside crosstool are linked against LRTE runtime they can pretty much run on any release of ubuntu or redhat.
For example:
# /usr/lrte/v2/bin/ldd /usr/crosstool/v2/gcc-4.9.2-lrtev2/x86/bin/clang
linux-vdso.so.1 (0x00007ffc388cf000)
