kdevplatform @1.3.1 fails to build: Undefined symbols "KDevelop::IPlugin::extensions() const"

[blixa@…]

I got the following linker error when compiling kdevplatform on OSX Lion 10.7.3/Xcode 4.3.2

I think the symbols can't be found in libkdevplatforminterfaces.5.0.0.dylib, but libkdevplatforminterfaces.5.0.0.dylib build fine

I have the same system configuration and I believe I am having the same problem. I have attached the log file for my failed build.

Cc Me!

Woot after hours (days ?) I finally made it.

But first, I must say that my problem was linking error with sublime. But when I tried to remove the tests and examples of sublime, the build process stopped at the same linking error as this ticket.

So, I was successful after installing macports clang-3.1 After an include file not found, I changed a line in :

/opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/kde/kdevplatform/work/kdevplatform-1.3.1/language/editor/modificationrevision.cpp

I changed the line :

#elif defined GXX_LT_4_3

for :

#elif defined GXX_LT_4_3 || __APPLE__

and it worked.

oops Forgot, I used

sudo port install kdevplatform configure.compiler=macports-clang

[blixa@…]

worked for me with apple's clang. thanks.

This issue should be fixed with commit r94069 following ticket #34545.
