dcmtk @3.6.1_20140617_1: error: DCMTK needs stringstream or strstream type

[ryandesign (Ryan Carsten Schmidt)]

dcmtk is failing to build for me on Mountain Lion. Errors include:

error: DCMTK needs stringstream or strstream type

error: Your C++ compiler cannot handle class templates:

error: Your C++ Compiler is not capable of compiling this code

Sounds like more older versions of clang need to be included in the compiler blacklist. I can try compiling with older MacPorts clang versions to narrow down the range.

[ryandesign (Ryan Carsten Schmidt)]

Just using a newer compiler doesn't help. macports-clang-3.4 still failed on Mountain Lion. Is it trying to use C++11 features perhaps? I'll try clang-3.5 after I've built that. But I can't explain why the port builds on Snow Leopard then, nor why it built fine on all the buildbot builders (except Snow Leopard, but that's #46099).

Neither std::strstream nor std::stringstream are C++11 features, but std::stringstream should at least be available?

Looking through the log, I see that it is grabbing headers from an installed (active) prior install of dcmtk. Try 'port deactivate dcmtk' followed by a clean and install of the updated dcmtk.

Replying to eborisch@…:

Thanks, that worked. Yowza, those are some astoundingly confusing and misleading error messages.

The conflicts_build portgroup could be used to work around this problem, until the real fix is implemented.

Committed conflicts_build setting in r129112.
