I cant get working my blas library with cmake. I have arch-linxux, both blas and cmake are installed with pacman. Cant understand where is problem :-(. I made cmake to print out the output of macro CHECK_FORTRAN_FUNCTION_EXISTS, because it fails there. Maybe I dont have proper configuration of ld?
My simple testing CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
project(Test C Fortran)
find_package(BLAS)
Error part from output:

I am trying to incorporate yaml-cpp into my project.
I have a "Demes" class where I need to parse a YAML file.
This is the relevant method in Demes.cpp:
#include "Demes.hpp"
void Demes::parse(const std::string& fileName)
{
YAML::Node test = YAML::LoadFile(fileName);
}
where Demes.hpp includes the yaml-cpp headers and declares the 'parse' method.
Building with make -VERBOSE=1 (as suggested by #Tsyvarev) gives:

I am using CMake to build my project, but I am still fairly unfamiliar with it.
EDIT: I forgot to mention that I have two CMakeLists.txt files, one inside src and the other inside the external build.
The start of my CMakeLists.txt file in the external build is:
cmake_minimum_required (VERSION 3.5.0)
project (momentspp CXX)
SET(CMAKE_CXX_FLAGS "-std=c++20 -Weffc++ -Wshadow -Wall -Wextra -ffast-math -O3 -march=native")
And the part of it where I look for yaml-cpp is:
FIND_PACKAGE(yaml-cpp REQUIRED)
IF(yaml-cpp_FOUND)
INCLUDE_DIRECTORIES(${yaml-cpp_INCLUDE_DIRS})
SET(LIBS {yaml-cpp_LIBRARIES})
MESSAGE("-- yaml-cpp libraries found here:")
MESSAGE(" includes: ${yaml-cpp_INCLUDE_DIRS}")
ENDIF()
My full CMakeLists.txt file inside src is:
SET(momentspp_CPP
Log.cpp
PolymorphismData.cpp
SumStatsLibrary.cpp
Drift.cpp
Migration.cpp
Mutation.cpp
Recombination.cpp
Epoch.cpp
Model.cpp
OptimizationWrapper.cpp
Demes.cpp
main.cpp
)
ADD_EXECUTABLE (momentspp ${momentspp_CPP})
SET(momentspp-targets momentspp)
FOREACH (target ${momentspp-targets})
TARGET_LINK_LIBRARIES(${target} ${BPP_LIBS_SHARED} ${BOOST_LIBS_SHARED} ${EIGEN3_LIBS_SHARED} ${yaml-cpp_LIBS_SHARED})
TARGET_LINK_LIBRARIES (${target} ${LIBS})
ENDFOREACH (target)
INSTALL(TARGETS ${momentspp-targets} DESTINATION ${CMAKE_INSTALL_BINDIR})
and this was working prior to the inclusion of yaml-cpp.
This feels like a rather complicated CMake set-up, but I am copying and editing it from a previous project where someone else helped me with it.
How can I fix the linking issue?
I tried looking similar questions around here, but couldn't get their solutions to work for me (apparently those people where not using CMake to build their projects).
Thank you,
Gustavo
I'm interested in statically linking PROJ to a library created with pybind11.
but, I get error by cmake.
Why am I getting this error and how can I fix it?
My CMakeLists.txt is this.
cmake_minimum_required(VERSION 3.4)
project(myearth LANGUAGES CXX)
add_subdirectory(pybind11)
pybind11_add_module(myearth MyEarth.cpp)
include_directories(${CMAKE_SOURCE_DIR}/PROJ/include)
add_library(proj4 STATIC IMPORTED)
set_target_properties(proj4 PROPERTIES IMPORTED_LOCATION ${CMAKE_SOURCE_DIR}/PROJ/lib/libproj.a)
target_link_libraries(myearth PRIVATE proj4)
CMake Error.
I think fPIC option is for shared library. so, libproj.a is not necessary this option because this is static library.

Thank you.
Shared libraries must have position independent code, but your version of PROJ was built without it; you will have to rebuild PROJ with PIC.
$ ./configure --prefix=/output --with-pic

Can somebody help please.
So, there was no issue with linking the winmm library it is just that I'm linking this to a wrong target. It was a dependency of the windows port in freeRTOS/Source/Portable.

There is no file named 'libsumo_swig_compilation' under "/home/cc/src/plexe-sumo/src/libsumo".
Then I checked the error log file, but the errors shown are about pthread saying 'undefined reference to pthread_creat' and 'cannot find -lpthreads'. Actually my pthread library is installed at 'libc6: /lib/x86_64-linux-gnu/libpthread.so.0'.
So I was wondering what's the exact problem here and how to solve it. I'm using a virtual machine with ubuntu 16. I appreciate your help!

My assumption is that this is really a behavior which only the new cmake shows. You could try to rename all references to libsumo in the java part of the CMakeLists.txt or simply use the CMakeLists of the main line sumo here: https://github.com/eclipse/sumo/blob/master/src/libsumo/CMakeLists.txt

I also should note that the libVC.a is in lib sub dir of my project, and all other source codes are in source sub dir. the main function is also in libVC.a, which is static.
Try changing the name as oLen suggested, this behavior is seen in some versions of Cmake. You can check another version if you insist on using the same name.
