Did you build libzmq as a static library? Is there a libzmq.a or only a libzmq.so?
the libs have been installed from a package not compiled.
I do have the 2 files :
/usr/lib/x86_64-linux-gnu/libzmq.so
/usr/lib/x86_64-linux-gnu/libzmq.a
BTW I'm on Ubuntu 18.04
Any updates?
Same issue in Ubuntu 20.04 I have both shared and static libzmq as well: /usr/lib/aarch64-linux-gnu/libzmq.a /usr/lib/aarch64-linux-gnu/libzmq.so
cppzmq version 4.8.1, ZeroMQ installed through apt-get (libzmq3-dev version 4.3.2)
Hello,
I encounter the same problem. I am using cppzmq, built manually. I used apt to get libzmq. I have both static and shared libs for cppzmq and libzmq.
Actually I cannot link statically cppzmq into my project, which is a big problem for deployments ...
find_package(cppzmq REQUIRED)
target_link_libraries(myTarget PUBLIC cppzmq cppzmq-static)
The error is : /usr/bin/ld: cannot find -llibzmq-static
I use Ubuntu 18.04 and CMake 3.10.
Same issue with cppzmq-static with MSVC with CMake 3.26.3
My CMakeLists.txt contains following:
include(ExternalProject)
ExternalProject_Add(
ZeroMQ
GIT_REPOSITORY https://github.com/zeromq/libzmq.git
GIT_TAG v4.3.4
CMAKE_ARGS -DCMAKE_MODULE_PATH:PATH=${CMAKE_INSTALL_PREFIX} -DCMAKE_INSTALL_PREFIX:PATH=${CMAKE_INSTALL_PREFIX} -DBUILD_TESTS=OFF -DBUILD_STATIC=ON
)
ExternalProject_Add(
cppzmq
DEPENDS ZeroMQ
GIT_REPOSITORY https://github.com/zeromq/cppzmq.git
GIT_TAG v4.10.0
CMAKE_ARGS -DCMAKE_MODULE_PATH:PATH=${CMAKE_INSTALL_PREFIX} -DCMAKE_INSTALL_PREFIX:PATH=${CMAKE_INSTALL_PREFIX} -DCPPZMQ_BUILD_TESTS=OFF
)
and then
target_link_libraries(myTarget PUBLIC cppzmq-static)
Then I go to my MSVC project and don't see Additional Include Directories and only cppzmq-static.lib in the Additional Directories. Additional Library Directories has no path to the library.
find_package(cppzmq)
seems to work as:target_link_libraries(exe cppzmq)
is workingbut
target_link_libraries(exe cppzmq-static)
does not work as it tries to link with a lib cppzmq-static :/usr/bin/ld: cannot find -llibzmq-static
