digikam git build failed, possibly missing lensfun

[Wolfgang Mader]

Hello,

I am new to the list.

I try to compile digikam from git on arch linux; qt and kde come from git also
and are installed under /usr/. I followed

http://www.digikam.org/download/GIT

The execution of bootstrap.linux issued the following warning:


----- bootstrap.linux -----
CMake Warning at /usr/share/apps/cmake/modules/KDE4Macros.cmake:1062
(add_library):
  Cannot generate a safe linker search path for target digikamcore because
  files in some directories may conflict with libraries in implicit
  directories:

    link library [libz.so] in /usr/lib64 may be hidden by files in:
      /lib64

  Some of these libraries may not be found correctly.
Call Stack (most recent call first):

I think they are not crutial since on arch all lib directories are symlinks to
/usr/lib.

After changing into the build directory, make gives this error

----- make error -----

lensefun is installed. What am I missing? Headers? Do I have to install libfun
from source?

I saw that bootstrap.linux sets up LD_LIBRARY_PATH. Is this needed for
whenever I want to compile digikam?

Thank you.
Best,
Wolfgang

P.s.: I anyone installing digikam using kde-srcbuild?
