ChangeLog
=========
- grte-1.2.2-src.tar.bz2 -> grte with sources stripped
Install and Usage
=================
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/bazelment/lrte/releases/download/v3.0_0 ./' >> /etc/apt/sources.list
apt-get update
apt-get install -y --force-yes lrtev3-crosstoolv2-gcc-4.9 lrtev3-crosstoolv2-clang-4.0
```
On the production machines, you should need to install
```lrtev3-runtime``` package, which contains the glibc and libstdc++
libraries.
Then gcc and clang under /usr/crosstool/v3/gcc-4.9.2-lrtev3/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/v3/bin/ldd /usr/crosstool/v3/gcc-4.9.2-lrtev3/x86/bin/clang
linux-vdso.so.1 (0x00007ffc388cf000)
libdl.so.2 => /usr/lrte/v3/lib64/libdl.so.2 (0x00007f6e55453000)
libpthread.so.0 => /usr/lrte/v3/lib64/libpthread.so.0 (0x00007f6e55236000)
libz.so.1 => /usr/lrte/v3/lib64/libz.so.1 (0x00007f6e5501c000)
libstdc++.so.6 => /usr/lrte/v3/lib64/libstdc++.so.6 (0x00007f6e54d12000)
libm.so.6 => /usr/lrte/v3/lib64/libm.so.6 (0x00007f6e54a0a000)
libgcc_s.so.1 => /usr/lrte/v3/lib64/libgcc_s.so.1 (0x00007f6e547f4000)
libc.so.6 => /usr/lrte/v3/lib64/libc.so.6 (0x00007f6e54431000)
/usr/lrte/v3/lib64/ld-linux-x86-64.so.2 (0x00007f6e55657000)
```
