Environment

• Linux pop-os x86_64 GNU/Linux
• Conan 2.0.9
• CMake 3.25.1
• Coin-utils 2.11.6
• Coin-osi 0.108.7
• Coin-clp 1.17.7
• C++20

Current structure

The MWE can be found here.

##### SETs
set (CMAKE_BUILD_TYPE Release) 
set (CMAKE_CXX_STANDARD 20)
set (BUILD_SHARED_LIBS On)

##### Additional packages 

find_package (coin-utils REQUIRED)

file(GLOB_RECURSE SOURCES "src/*.cpp")

add_executable( main ${SOURCES} )

target_link_libraries(main pthread m dl)

• src/main.cpp:

#include "coin/OsiClpSolverInterface.hpp"

int main (int argc, const char *argv[])
{
    OsiClpSolverInterface model;
    return 0;
}

Process

mkdir build
conan install . --profile conanprofile.txt --output-folder=build --build=missing
cd build
cmake .. --preset conan-release
make

Expected result

[ 50%] Building CXX object CMakeFiles/main.dir/src/main.cpp.o
[100%] Linking CXX executable main
[100%] Built target main

Actual result

[ 50%] Linking CXX executable main
/usr/bin/ld: CMakeFiles/main.dir/src/main.cpp.o: in the function `main':
main.cpp:(.text.startup+0x56): reference to `OsiClpSolverInterface::OsiClpSolverInterface()' not defined
/usr/bin/ld: main.cpp:(.text.startup+0x5e): reference to `OsiClpSolverInterface::~OsiClpSolverInterface()' not defined
collect2: error: ld returned 1 exit status

make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/main.dir/all] Error 2
make: *** [Makefile:91: all] Error 2

Goal

Fix the compilation.

Guess

Probably we have to set the target_link_libraries accordingly.

Thanks and regards.

[matheusdiogenesandrade]

Thanks for the attention. I already managed this. Suffices to add the following target link libs:

target_link_libraries(main 
  coin-clp::coin-clp
  coin-osi::coin-osi
  pthread m dl
)

However, it seems that the CBC still has no integration with Conan 2.x.
