Qpid proton C++ static link

[Attila Kalcsú <at...@gmail.com>]

Hello,

I would like to static linking qpid proton c++ static libraries to my
executeable binary.

I've used the 'client' example codes to compile & build & run with static
lib linking.

---------------------------------------------------------------
command line
---------------------------------------------------------------

git clone https://github.com/apache/qpid-proton.git
cd qpid-proton
git checkout tags/0.29.0
mkdir _build
cd _build
cmake .. -DBUILD_WITH_CXX=ON -DBUILD_STATIC_LIBS=ON
make -j4
make install
sudo make install
sudo ldconfig

---------------------------------------------------------------

After these steps I found 3 qpid static library in the "/usr/local/lib/ "

-libqpid-proton-core-static.a

-libqpid-proton-proactor-static.a

-libqpid-proton-static.a


So I've created a CMakeLists.txt to link .a files:

---------------------------------------------------------------
Content of CMakeLists.txt:
---------------------------------------------------------------
add_executable (x main.cpp)

set(CMAKE_CXX_STANDARD 17)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -v -std=c++17 -lpthread
-static-libgcc -static-libstdc++ -fdiagnostics-color=auto")

include(ExternalProject)

add_library(qpid1 STATIC IMPORTED)
set_property(TARGET qpid1 PROPERTY IMPORTED_LOCATION
/usr/local/lib/libqpid-proton-core-static.a)
add_library(qpid2 STATIC IMPORTED)
set_property(TARGET qpid2 PROPERTY IMPORTED_LOCATION
/usr/local/lib/libqpid-proton-proactor-static.a)
add_library(qpid3 STATIC IMPORTED)
set_property(TARGET qpid3 PROPERTY IMPORTED_LOCATION
/usr/local/lib/libqpid-proton-static.a)

target_link_libraries(x qpid1 qpid2 qpid3)

---------------------------------------------------------------

But the result log is (snippets):
