dockpack.base_boost

base_boost is an Ansible role that installs libraries for the GNU C++ compiler tools.

Requirements

You need a RHEL-like system, Ubuntu, or Windows.

Role Variables

Corporate feature: controls the desired state
```
compilers_present: present
```
Software collections provide the latest versions of programming languages. Set this to true to use the gcc-toolkit on CentOS 8.
```
collections_enabled: true
```
Approved/test release of software collections' devtoolset
```
cplusplus_devtoolset: devtoolset-7
```

Most Boost libraries only require header files, meaning they don’t need separate compiled library files. However, this role does compile some libraries. You can change this if you want:

compile_boost: true

The only Boost libraries that need separate building have no extra documentation to compile and are set as defaults (you can change them in group_vars or your playbook):

compile_boost_with:
  --with-chrono
  --with-context
  --with-filesystem
  --with-graph_parallel
  --with-iostreams
  --with-locale
  --with-program_options
  --with-regex
  --with-serialization
  --with-signals
  --with-system
  --with-thread
  --with-timer
  --with-wave

Boost Compiler Flags for Windows

/DFOO - defines FOO in the preprocessor.
/EHsc - catches C++ exceptions; assumes extern "C" functions do not throw exceptions.
/GR - enables RTTI (Run-Time Type Information).
/MD - creates a multithreaded DLL.
/MDd - creates a debug multithreaded DLL.
/O1 - optimizes for size.
/O2 - optimizes for speed.
/Ob0 - does not use auto-inlining.
/Ob1 - only inlines functions marked inline and class member functions defined in a class.
/Ob2 - allows the compiler to inline freely.
/Od - no optimization.
/RTC1 - runs checks at runtime for uninitialized variables and frame errors. More details are on their site.
/W3 - sets warning level 3 (out of 4), for production quality.
/Zi - generates complete debugging information, similar to -g for clang/gcc.
