octastd
OctaSTD is a new "standard library" for C++14. It provides containers (dynamic arrays etc) as well as other utilities.
Documentation for OctaSTD can be found at https://wiki.octaforge.org/docs/octastd.
Full C++14 support is required in your compiler.
Supported compilers
| Compiler | Version |
|---|---|
| gcc/g++ | 5.4+, 6+ |
| clang | 3.8+ |
Other C++14 compliant compilers might work as well. OctaSTD does not utilize compiler specific extensions except certain builtin type traits - to implement traits that are not normally possible to implement without compiler support.
OctaSTD does not provide fallbacks for those traits. The compiler is expected to support these builtins. So far the 2 above-mentioned compilers support them (MSVC++ supports most of these as well).
While Clang 3.6 does implement a sufficient level of C++14 support, it suffers from a bug in its variable template implementation that prevents OctaSTD from functioning. Therefore version 3.8 or higher is necessary (where this bug was finally fixed).
GCC has implemented a sufficient feature level of C++14 since version 5.1, but also is too buggy until version 5.4. Version 5.1 and 5.2 have variable template partial specialization issues and version 5.3 has an internal compiler error triggered by the tuple implementation. Version 5.4 appears to be the first one to compile this without issues. GCC 6.1 also appears to compile without problems.
MSVC++ is currently unsupported. Support is currently being investigated and might be added at least for VS 2015 Update 2, assuming I don't run into any significant bugs or missing features. MSVC++ with Clang frontend will be supported once Microsoft updates it to Clang 3.8 (3.7 as is currently shipped suffers from the issue mentioned above).
Supported operating systems
Currently supported OSes in OctaSTD are Linux, FreeBSD and OS X. Other systems that implement POSIX API will also work (if they don't, bug reports are welcome).
OS X support requires Xcode 8 or newer to work. That is the first version to ship a Clang 3.8 based toolchain, so things will not compile with an older version of Xcode. Alternatively you are free to use any other supported compiler from other distribution channels (official Clang, homebrew gcc or clang, etc.).
Windows is supported with GCC (MinGW) and Clang. The MS C runtime is supported as well, so compiling with Clang targeting MSVC compatibility will work.
