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/dionescu/lrte/releases/download/lrtev2 ./' >> /etc/apt/sources.list
apt-get update
apt-get install -y --force-yes lrtev2-crosstoolv2-gcc-4.9 lrtev2-crosstoolv2-clang-4.0
Important: If you want to handle MSAN instrumented builds, you will
need to build an instrumented libstdc++ using the crosstool. To do
this, simply run the msan.sh script after you install LRTE
(note that you may need to modify the script if you installed LRTE
in a non-default location). The instrumented libstdc++ will be placed
under path_to_crosstool_base/gcc-4.9.2-lrtev2/x86/lib64/msan.
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 and 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)
