I cannot understand the reason. In the end, I want to send libparticles.a to another developer and let him use it. Any help is really appreciated since I stuck at this problem for a while now.
Its about how GCC links library, if the name of lib is particles try this
target_link_directories(another_project PRIVATE /home/path_to_dir_containing_lib_a_file)
target_link_libraries(another_project PRIVATE particles)
Please see this manual:
https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html
-l library
Search the library named library when linking. (The second alternative with the library as a separate argument is only for POSIX compliance and is not recommended.)
The -l option is passed directly to the linker by GCC. Refer to your linker documentation for exact details. The general description below applies to the GNU linker.
The linker searches a standard list of directories for the library. The directories searched include several standard system directories plus any that you specify with -L.
It means that dirs containing libraries are passed separatly (under another flag) from library name

I am using vcpkg for the first time with amqpcpp. I am testing it out with cmake to get a project setup using a library. vcpkg installs the package correctly and cmake has no trouble finding the target amqpcpp. There is some issue with the linker that I cannot solve. Below is my CMakeLists.txt.
cmake_minimum_required(VERSION 3.15)
set(VCPKG_TARGET_TRIPLET x86-windows )
set(CMAKE_TOOLCHAIN_FILE "C:/Users/reine/vcpkg/scripts/buildsystems/vcpkg.cmake" CACHE STRING "")
project(amqp_test)
set(CMAKE_CXX_STANDARD 11)
find_package(amqpcpp CONFIG REQUIRED)
include_directories(${amqpcpp_INCLUDE_DIR})
add_executable(amqp_test main.cpp)
target_link_libraries(${PROJECT_NAME} PRIVATE amqpcpp)
And below is the linker error that I am experiencing. The ConnectionImpl does indeed exist. Why are the file names so crazy? I imagine this is something that is done to prevent double referencing of an object. I am thinking this is where my problem is.

C:/Users/reine/vcpkg/installed/x86-windows/include/amqpcpp/connection.h:70: undefined reference to `AMQP::ConnectionImpl::~ConnectionImpl()'
I have done my due diligence searching this type of linker error and am completely stuck.

I have a problem with CMake: A static library and an executable are made but the build process is out of order. Thus, the library does not exist when the executable tries to link. I have read similar questions but did not find a solution. My project uses one root-CMakelists.txt that includes the other two:
Root: dev/CMakeLists.txt:
# Library project
include(${CMAKE_CURRENT_SOURCE_DIR}/src_lib/CMakeLists.txt)
# Client project
include(${CMAKE_CURRENT_SOURCE_DIR}/src_client/CMakeLists.txt)
Library: dev/src_lib/CMakeLists.txt
add_library(wof_static STATIC ${LIB_SRC})
TARGET_LINK_LIBRARIES(wof_static ${CMAKE_CURRENT_SOURCE_DIR}/3rdParty/lex/libs/amd64/libLexActivator.a pthread libnss3.so /usr/lib/x86_64-linux-gnu/libssl3.so /usr/lib/x86_64-linux-gnu/libnspr4.so )
Executable: dev/src_client/CMakeLists.txt
add_executable(wof ${CLIENT_SRC})
TARGET_LINK_LIBRARIES( wof
${CMAKE_CURRENT_SOURCE_DIR}/build/libwof_static.a
${CMAKE_CURRENT_SOURCE_DIR}/src_lib/3rdParty/lex/libs/amd64/libLexActivator.a
gmp
pthread
libnss3.so
/usr/lib/x86_64-linux-gnu/libssl3.so
/usr/lib/x86_64-linux-gnu/libnspr4.so
)
The above TARGET_LINK_LIBRARIES command uses the filename libwof_static.a, and thus, the build is out of order (i.e., it works only when I call make twice). Thus, I need to let CMake know that the executable depends on the library-target wof_static, right? I tried to do so:
Executable: dev/src_client/CMakeLists.txt (variant)
link_directories(${CMAKE_CURRENT_SOURCE_DIR}/build/ ${CMAKE_CURRENT_SOURCE_DIR}/src_lib/3rdParty/lex/libs/amd64/)
add_executable(wof ${CLIENT_SRC})
TARGET_LINK_LIBRARIES( wof
wof_static
${CMAKE_CURRENT_SOURCE_DIR}/src_lib/3rdParty/lex/libs/amd64/libLexActivator.a
gmp
pthread
libnss3.so
/usr/lib/x86_64-linux-gnu/libssl3.so
/usr/lib/x86_64-linux-gnu/libnspr4.so
)
The intention of the above is to let CMake know the target name wof_static. That seems to work because the compilation of the executable wof starts when the library is ready. But I assumed that CMake would know and use the output file libwof_static.a of the target wof_static. This does not seem to be true. The error I get is:

In your file dev/src_client/CMakeLists.txt, this line:
${CMAKE_CURRENT_SOURCE_DIR}/src_lib/3rdParty/lex/libs/amd64/libLexActivator.a
evaluates to the path:
dev/src_client/src_lib/3rdParty/lex/libs/amd64/libLexActivator.a
I don't think that is what you intend, as this path is different from the path you use in the dev/src_lib/CMakeLists.txt file.
Instead of CMAKE_CURRENT_SOURCE_DIR, use the CMake variable that points to the root source directory: CMAKE_SOURCE_DIR. Try something like this:
TARGET_LINK_LIBRARIES( wof
wof_static
${CMAKE_SOURCE_DIR}/src_lib/3rdParty/lex/libs/amd64/libLexActivator.a
gmp
pthread
libnss3.so
/usr/lib/x86_64-linux-gnu/libssl3.so
/usr/lib/x86_64-linux-gnu/libnspr4.so

I get the source code of percona-server from github. And I install boost 1.59 and gcc gcc-c ncurses-devel. I enter the directory of percona-server and run "cmake --DWITH_BOOST=/data/boost" but get the following error. I cannot find some solution so I came to here. Thanks!!

I am trying to compile a Fortran program using CMake on an IBM BlueGene machine. This is my source:
> tree
.
├── CMakeLists.txt
└── src
└── test1.f90
where test1.f90 simply is:
program main
use mpi
integer :: me, ierr
call MPI_Init(ierr)
call MPI_Comm_rank(MPI_COMM_WORLD, me, ierr)
write (*,"(I4,A)") me, ": hello"
call MPI_Finalize(ierr)
end program main
I would like to create a static executable. Therefore I created this CMakeLists.txt:
cmake_minimum_required(VERSION 2.5)
project(STB)
file(GLOB_RECURSE sources src/*.f90)
SET(CMAKE_FIND_LIBRARY_SUFFIXES ".a")
SET(BUILD_SHARED_LIBRARIES OFF)
SET(CMAKE_EXE_LINKER_FLAGS "-static")
add_executable(test.x ${sources})
enable_language(Fortran)
set(CMAKE_Fortran_COMPILER_ID "IBM")
if(CMAKE_Fortran_COMPILER_ID MATCHES "IBM")
MESSAGE(STATUS "IBM")
set(CMAKE_Fortran_COMPILER mpixlf2008)
set(dialect "-O2 -qarch=qp -qtune=qp -ufmt_littleendian={23}")
set(debug "-C")
endif()
set(CMAKE_Fortran_FLAGS_DEBUG "${CMAKE_Fortran_FLAGS_DEBUG} ${bounds}")
set(CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} ${dialect}")
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/")
MESSAGE( STATUS "cmake_module_path: " ${CMAKE_MODULE_PATH})
this results in:

mpixlf2008 -static -O2 -qarch=qp -qtune=qp -ufmt_littleendian={23} CMakeFiles/test.x.dir/src/test1.o -o test.x
I get the error:
/bgsys/drivers/ppcfloor/gnu-linux/powerpc64-bgq-linux/bin/ld: -f may not be used without -shared
How can I compile my program using statically using CMake? If I simply run:
mpixlf2008 -c src/test1.f90
mpixlf2008 test1.o -o bla.x
The compilation works fine and the size(45M) suggest, that it's compiled statically.
Edit:
If I remove the little endian flag:
set(dialect "-O2 -qarch=qp -qtune=qp")
I can run the cmake created makefile and then manually remove the -rdynamic
mpixlf2008 -static -O2 -qarch=qp -qtune=qp CMakeFiles/test.x.dir/src/test1.o -o test.x
Which then successfully compiles. How can I remove the -rdynamic from the CMake Makefile?
Try adding -qstaticlink to your link line instead of adding -static / -rdynamic directly. When you use the mpixlf2008 command, the compiler inserts its own -static / -rdynamic options to link in its own libraries, so the options you added are probably interfering with the ones the compiler is using. The -qstaticlink option tells the compiler you want a completely static binary. The option also has suboptions that would allow you to only statically link the gcc libraries.
Also, the specific error you're getting is because you specified "-rdynamic". XLF doesn't know this option, so it assumes it's a grouping of smaller options. So it parses it as: "-r -d -ynamic". -r is for creating a nonexecutable output file, -d is for saving preprocessed output, -y is for specifying compile-time rounding mode. The -y option takes a suboption for the rounding mode, e.g. -yn for nearest. The error you're getting is that namic is not a known suboption of -y. To pass -rdynamic to the linker, put -Wl, before it. i.e. "-Wl,-rdynamic".
Adding
set(CMAKE_SHARED_LIBRARY_LINK_Fortran_FLAGS)
allows me to remove the '-rdynamic'. This might be a bit manual, but for older CMake versions it works.
I have these files in the directory:
CMakeLists.txt datalink.c datalink.h protocol.a protocol.h
All these files were got from my teacher except CMakeLists.txt.
#CMakeLists.txt
cmake_minimum_required(VERSION 3.5)
project(DataLinkSimulator)
INCLUDE_DIRECTORIES(.)
set(SOURCE_FILES datalink.c protocol.a datalink.h protocol.h)
add_executable(DataLinkSimulator ${SOURCE_FILES})
target_link_libraries(DataLinkSimulator protocol.a)
I run 'cmake .' in this directory, and it works.
However, when I run 'make' , it gives me these errors.

The error "cannot find -lprotocol" must caused by ld's mistaking protocol as a shared lib. But my protocol is a static lib. So I am confused.
If I edit makefile by myself instead of using cmake, it works correctly.

Makefile:83: recipe for target 'all' failed

In order to understand the error you need to launch make command from the command line using verbose mode; on Linux paltform it means launching:
make VERBOSE=1
In this manner you will have the entire command line used to compile the code.
In order to resolve your error you could:
add a link_directories(directory_where_you_have_library) CMake line adding the directory where you have protocol.a before target_link_libraries line
add protocol.a with absolute path.
Your modified Makefile works because probably you have it in the same directory of all the files while CMake creates many Makefiles in various directories starting from build root directory so it needs -L gcc flags (obtainable through link_directories) or -l with absolute path (obtainable adding protocol.a with absolute path).
