Can't install kdevplatform

[ryandesign (Ryan Carsten Schmidt)]

This was not a clean attempt. Please "sudo port clean kdevplatform" and try again, then attach the new main.log.

There's definitely an issue with CXX compiler for this if you're using OS X Lion and Xcode 4.3 (latest and "greatest" version 4.3.2 :-S).

If I use clang to build kdevplatform I can get past this problem, but then I get tripped up further down the line by a #include of unordered_map which for some reason clang cannot see since it's an early-style STL header (on my system it lives in /usr/include/c++/v1/).

If I use llvm-g++-4.2 then I get the same problem that is listed in this ticket (and a few earlier ones).

This is what I did to build with clang:

1) sudo port clean kdevplatform 2) sudo port fetch kdevplatform 3) sudo port extract kdevplatform 4) cd /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/kde/kdevplatform/work/build 5) sudo cmake ../kdevplatform-1.3.1/ --> this at least on my system forces clang to be the CXX compiler. I guess you can explicitly set it to clang by passing -D CMAKE_CXX_COMPILER=clang as an argument to cmake 6) sudo make

And then I get tripped up by the #include <unordered_map>.

      'unordered_map' file not found

Clang doesn't seem to see it by default and I haven't got round to figuring out how to add a library import to CMakeCXXCompiler.cmake file.

I hope this helps.

Sorry about the formatting above, here are the steps laid out in a more readable fashion

1) sudo port clean kdevplatform
2) sudo port fetch kdevplatform
3) sudo port extract kdevplatform
4) cd /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/kde/kdevplatform/work/build
5) sudo cmake ../kdevplatform-1.3.1/ --> this at least on my system forces clang to be the CXX compiler. I guess you can explicitly set it to clang by passing -D CMAKE_CXX_COMPILER=clang as an argument to cmake
6) sudo make

Yeah, I got as far as dragan did with clang, and stopped there. Actually, <unordered_map> is available in C++11, so probably you just need to enable the C++11 option to Clang.

[dave@…]

With the following cmake command you can get all the way to link errors:

sudo port install clang-3.1
sudo cmake "-DCMAKE_CXX_COMPILER=$(which clang-mp-3.1)" "-DCMAKE_CXX_FLAGS=-std=c++11 -Wno-reserved-user-defined-literal" ../kdevplatform-1.3.1

It seems to be missing the runtime libraries for something (see my attachment). It's my wild guess that kdelibs4 and any other parts on which kdevelop depends need to be built with clang, too. Maybe someone else can get further than I.

BTW, if someone with the privileges to do so could edit out the body of the bug report (which is superseded by my attached log) I would be grateful.

Done.
