Marcus,
I have tracked this up one more file. The file:
build/gnuradio-runtime/swig/CMakeFiles/Export/lib/cmake/gnuradio/runtime_swigTargets.cmake
on the host system has lines starting around line 44:
# Compute the installation prefix relative to this file.
get_filename_component(_IMPORT_PREFIX "${CMAKE_CURRENT_LIST_FILE}" PATH)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
if(_IMPORT_PREFIX STREQUAL "/")
set(_IMPORT_PREFIX "")
endif()
Where as the on on the cross-compile has lines:
# Compute the installation prefix relative to this file.
get_filename_component(_IMPORT_PREFIX "${CMAKE_CURRENT_LIST_FILE}" PATH)
# Use original install prefix when loaded through a
# cross-prefix symbolic link such as /lib -> /usr/lib.
get_filename_component(_realCurr "${_IMPORT_PREFIX}" REALPATH)
get_filename_component(_realOrig "/usr/lib/cmake/gnuradio" REALPATH)
if(_realCurr STREQUAL _realOrig)
set(_IMPORT_PREFIX "/usr/lib/cmake/gnuradio")
endif()
unset(_realOrig)
unset(_realCurr)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
if(_IMPORT_PREFIX STREQUAL "/")
set(_IMPORT_PREFIX "")
endif()
I have found a bug report with another project, which looks close to my
error, but I cannot see that is was ever fixed:
https://bugs.launchpad.net/ubuntu/+source/pugixml/+bug/1799660
Thanks
Toby
