Hello,
I have a simple cmake file for a small project. That project uses boost and
links again a shared lib that also uses boost:
find_library(precice precice PATHS $ENV{PRECICE_ROOT}/build
$ENV{PRECICE_ROOT}/build/last)
find_package(Boost 1.60.0 REQUIRED COMPONENTS system program_options filesystem)
add_executable(preciceMap src/preciceMap.cpp src/common.cpp)
target_include_directories(preciceMap PRIVATE ${Boost_INCLUDE_DIRS})
target_link_libraries(preciceMap ${Boost_LIBRARIES})
target_link_libraries(preciceMap ${precice})
output is:

CMake finds boost 1.66 but why does it try to link against 1.54.0? $BOOST_ROOT
is set and $LIBRARY_PATH, $LD_LIBRARY_PATH and $CPLUS_INCLUDE_PATH are also set
appropriately.
:~/software/aste/build> ls $BOOST_ROOT/lib/*filesystem*
/opt/hlrs/tools/boost/1.66.0/lib/libboost_filesystem.a
/opt/hlrs/tools/boost/1.66.0/lib/libboost_filesystem.so
/opt/hlrs/tools/boost/1.66.0/lib/libboost_filesystem.so.1.66.0
:~/software/aste/build> ls /usr/lib64/*filesystem*
/usr/lib64/libboost_filesystem-mt.so /usr/lib64/libboost_filesystem.so
/usr/lib64/libboost_filesystem.so.1.54.0
Maybe it prefers the -mt variants? But how can I get it to link against the
correct files, i.e., 1.66?
Or is the "DSO missing from command line" another problem? All I found about
that is that boost_system should be added, but that's already the case.
cmake version is 3.5.2
Can you run make with VERBOSE=1 and give as the output please?
To me it looks like, that cmake discards the library directory and links
with -lboost_filesystem instead of the fullpath. This happened in my
environment whenever the environment variable LIBRARY_DIR contains the
boost library directory.
Nevertheless, you should unset LIBRARY_DIR with cmake. Otherwise, the
compiler gcc will treat the folders in this variable as system folders.
Thanks,
Florian
