CMake libqt4-dev Multilib problem

[Pascal Spörri]

Hi Everyone,

I have an already running cmake program that I was unable to compile on oneiric:
(In order to compile it I needed to add the path: /usr/lib/x86_64-linux-gnu/ to LD_LIBRARY_PATH)

cmake_minimum_required(VERSION 2.6.2)
project(BarnesHutGPU_CSELAB)
set(CMAKE_BUILD_TYPE Debug)
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/CMake" ${CMAKE_MODULE_PATH})
set(CUDPP_ROOT_DIR "${CMAKE_SOURCE_DIR}/../cudpp/" CACHE PATH "CUDPP Root dir" FORCE)
find_package(CUDA 4 QUIET REQUIRED)
find_package(CUDPP REQUIRED)

[Some cuda stuff here]
#### QT
find_package(Qt4 REQUIRED)
include(${QT_USE_FILE})
include_directories(${QT_INCLUDES} ${CUDPP_INCLUDE_DIR} ${CMAKE_CURRENT_SOURCE_DIR}/../data_import/src/ ${CMAKE_CURRENT_SOURCE_DIR}/../cuda_includes/)
[...]
cuda_add_executable(BarnesHutGPU_CSELAB ${MAIN_SRCS} ${PS_SRCS})
target_link_libraries(BarnesHutGPU_CSELAB ${QT_LIBRARIES} ${CUDPP_LIBRARY})

But somehow cmake has problems detecting the correct qt version:

make[2]: *** No rule to make target `/usr/lib/libQtGui.so', needed by `BarnesHutGPU_CSELAB'. Stop.
make[1]: *** [CMakeFiles/BarnesHutGPU_CSELAB.dir/all] Error 2
make: *** [all] Error 2

libqt4-dev is installed but dpkg -L libqt4-dev shows:

[...]

I have the same problem. And no solution yet - sorry :)
Just wanted to note that I do not have to modify LD_LIBRARY_PATH, as ldconfig is configured correctly to locate libraries:

> cat /etc/ld.so.conf.d/x86_64-linux-gnu.conf
# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu

Still, the problem persists.
Must be somewhere in FindQt.cmake I assume.

cheers
Michael

The weird thing is that I'm able to compile it on my desktop, which
was an upgrade from 11.04, but I got the problem on my laptop which is
a fresh install.

Status changed to 'Confirmed' because the bug affects multiple users.

[Rockroehre (rockroehre)]

I'm having the same problem after a clean install of 12.04:

error msg:
No rule to make target `/usr/lib/libQtGui.so', needed by `foo'. Stop.

cat /etc/ld.so.conf.d/x86_64-linux-gnu.conf
# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu

[Rockroehre (rockroehre)]

Deleting the CMakeCache.txt file for the project fixed it for me.

Deleting CMakeCache.txt worked for me too.

[Gianfranco Costamagna (costamagnagianfranco)]

closing then, maybe was a cache issue.
