unordered prime_list_template release-only link problem with sunpro toolset

[jhamm@…]

Missing symbol on sun solaris for release build of a project using unordered. We are currently using:

Sun C++ 5.9 SunOS_sparc Patch 124863-05 2008/06/03

The related shared objects and executable compile cleanly without warnings. When the shared object is linked at runtime, the executable cannot link due to a missing symbol for

prime_list_template<T>::length = 28;

The original code works for debug versions, so we suspect a compiler bug or perhaps an inlining problem.

Here is our solution:

* * 81,87 --- 81,95 ----

template<typename T> struct prime_list_template {

static std::size_t const value[];

+ #if defined(SUNPRO_CC)

+ static std::ptrdiff_t const length = 28;

+ #else

static std::ptrdiff_t const length;

+ #endif

};

template<typename T>

* * 93,100 --- 101,113 ----

50331653ul, 100663319ul, 201326611ul, 402653189ul, 805306457ul, 1610612741ul, 3221225473ul, 4294967291ul };

+ #if !defined(SUNPRO_CC)

template<typename T> std::ptrdiff_t const prime_list_template<T>::length = 28;

+ #endif

typedef prime_list_template<std::size_t> prime_list;

(In [59200]) Set length of primes inside template on Sun C++. Refs #3854

The library has changed a fair amount since 1.37 so that patch doesn't apply any more. I just checked in a fix for the issue on trunk, but it's quite possible that there will be other similar problems with the new version.

(In [59911]) Merge hash and unordered from trunk.

• Replace uses of deprecated C++0x macros
• Set length of primes inside template on Sun C++. Fixes #3854
• Missing newline at end of file.
