Hi,
While I was trying to fix FACT-1559[1], which is a trivial 2 lines fix,
I embarked in an endless and very frustrating journey of trying to build
facter.
I was able to rebuild facter in isolation on an ubuntu 16.04, once all
the dependencies were fulfilled correctly.
But when I tried to build in the context of the puppet-agent package so
that my facter build would:
* be able to replace the shipped facter
* use the /opt/puppetlabs embedded ruby
* use the various /opt/puppetlabs/puppet/lib shipped library
I encountered an endless stream of issues:
* impossibility to build with static boost and/or static yaml-cpp, I
kept getting link errors about:
/usr/bin/ld:
/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libyaml-cpp.a(parse.cpp.o):
relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a
shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libyaml-cpp.a: error
adding symbols: Bad value
or
/usr/bin/ld:
/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libboost_locale.a(format.o):
relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a
shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libboost_locale.a:
error adding symbols: Bad value
* if building a full dynamic lib, I get numerous boost link issues like
those:

`std::_Function_handler<unsigned long (),
facter::ruby::module::ruby_search_external(unsigned long, unsigned

...
It's like if boost libs weren't there, but they seem specified in the
linker command line arguments. Cmake found them correctly.
I haven't done any serious C++ programming in the last 15 years, so I'm
all rusty (no pun intended of course), and I might have missed something
essential.
That would be great to be able to rebuild facter with my fix (I'm not
sure what's the plan on facter release nowadays, but I don't expect to
see an updated puppet-agent with facter including this coreos fix in a
timeframe that would allow me to make progress on my side).
My cmake looks like this:
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 cmake
-DLEATHERMAN_GETTEXT=OFF \
-DCMAKE_VERBOSE_MAKEFILE=ON \
-DCMAKE_PREFIX_PATH=/opt/puppetlabs/puppet \
-DCMAKE_INSTALL_PREFIX=/opt/puppetlabs/puppet \
-DCMAKE_INSTALL_RPATH=/opt/puppetlabs/puppet \
-DRUBY_INCLUDE_DIR=/opt/puppetlabs/puppet/include/ruby-2.1.0/ \
-DBOOST_STATIC=OFF \
-DCMAKE_POSITION_INDEPENDENT_CODE=ON \
-DYAMLCPP_STATIC=OFF \
-DAIO_AGENT_VERSION=1.8.0 \
-DINSTALL_BATCH_FILES=NO \
..
Any help is welcome :)
