Hi,
I'm trying to build a Debian package but I have found a problem with a
libboost dependency. I'm totally new to building Debian packages. I'm
using bzr builddeb for building. It generates a .dsc file containing:
...
Build-Depends: debhelper (>= 8.0.0), libfreetype6-dev,
libunittest++-dev (>= 1.3.0), zlib1g (>= 1:1.1.4), libpng-dev,
libboost-date-time-dev, libboost-thread-dev
...
But when all files are compiled and it is going to link, it fails with the following error (from .build log):
...
/datos/USR/lm/build/lomse/build-area/lomse-0.12.4/obj-i686-linux-gnu/bin/testlib: error while loading shared libraries: libboost_date_time.so.1.42.0: cannot open shared object file: No such file or directory
...
At this point I'm completely lost because libboost_date_time version 1.42.0 is installed in my machine, as dpkg shows:
$ dpkg -l | grep 'boost'
ii libboost-date-time-dev 1.48.0.2

ii libboost1.46-dev 1.46.1-7ubuntu3 Boost C++ Libraries development files
$
Also, I do not understand why it tries to link to version 1.42.0. The
point is that I use CMake for generating the makefile. Before
attempting to build the Debian package I have tested my CMakeList.txt
file. I can generate the makefile, and build from the command line, by
doing:
$ cmake -G "Unix Makefiles" ../sources
$ make
This works perfectly.
My debian/rules file contains:
#!/usr/bin/make -f
include /usr/share/cdbs/1/rules/debhelper.mk
include /usr/share/cdbs/1/class/cmake.mk
In the build log (file .build) I see that libboost 1.46.1 is found:
...
-- Boost version: 1.46.1
-- Found the following Boost libraries:
-- date_time
-- thread
Boost found: libraries: /usr/lib/libboost_date_time-mt.so;/usr/lib/libboost_thread-mt.so;pthread
Boost found: include= /usr/include
Boost found: libdir= /usr/lib
Boost found: version= 1_46_1
...
Those lines are generated by CMakeList.txt file, containing:
...
# Check for Boost >= 1.42.0
set(Boost_ADDITIONAL_VERSIONS "1.42" "1.42.0" "1.43" "1.43.0" "1.44" "1.44.0"

"1.50" "1.50.0" )
#set(Boost_USE_STATIC_LIBS OFF)
#set(Boost_USE_MULTITHREADED OFF)
#set(Boost_USE_STATIC_RUNTIME OFF)
#set(Boost_DEBUG TRUE)
find_package(Boost 1.42.0 COMPONENTS date_time thread REQUIRED)
if(Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
link_libraries( ${Boost_LIBRARIES} )
link_directories( ${Boost_LIBRARY_DIRS} )
message("Boost found: libraries: ${Boost_LIBRARIES}" )
message("Boost found: include= ${Boost_INCLUDE_DIRS}" )
message("Boost found: libdir= ${Boost_LIBRARY_DIRS}" )
message("Boost found: version= ${Boost_LIB_VERSION}" )
else()
message(SEND_ERROR "Boost package not found. Reason: ${Boost_ERROR_REASON}" )
endif()
...
As in no place in my CMakeList.txt file nor in any other debian/ file I point to 1.42.0 version, but to the found version, I do not understand why it tries to use version 1.42.0 instead of 1.46 and from where the 1.42.0" string comes. But in any case, both are present!
I would greatly appreciate any clues or help to solve this issue. I'm a newbie on this (my first deb package) and I am completely lost.
Thank you in advance.
