This is not a debug build. Restart cmake with the options I provided and please use pastebin for large texts. Have you read this?

[mukhal]

Yes I read the manual. Here's the pastepin of the output : [http://pastebin.com/Znc6pYs5]

This is what the debug make output should look like. I need to see the command that fails. Please start a complete new checkout.

git clone https://github.com/albertlauncher/albert.git
mkdir albert-build
cd albert-build
cmake ../albert -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug
make | tee pastebin.txt

[mukhal]

Done that. Here it 's http://pastebin.com/kDAPQZhN

It seems the error occurs when building xdg_automoc.cpp.o

[ManuelSchneid3r]

This is not a new checkout and not a new rebuild. I dont know what you are linking, but we do not import that libPRIVATE. I will close this one since it is not reproducible on the target system. Just use the ppas in the docu.

Do you use a special verison of Qt, cmake or a particular c++ compiler? Whats your cmake version? This seems related to the cmake link_private stuff.

[ManuelSchneid3r]

The privat link interface was introduced in 2.8.12 . If you have <2.8.12 and this was your problem albert should not compile anymore on your machine. (7ecc7a235423116eece23d6115ed0d8894bb149a)

[mukhal]

cmake 2.8.11 g++ 4.8.4

I'll update cmake and see what happens

[mukhal]

Fixed by completely removing and reinstalling cmake
