Boost Linker Error

[white valley]

I am trying to add boost::thread to my application, but I get this link error. I have the proper include path in the compiler, and I have -pthread specified in the linker. I am not sure what I am doing wrong.

CMake Error at CMakeLists.txt:52 (target_link_libraries):
  Target "boost_thread" links to:

    Boost::assert

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

CMake Generate step failed.  Build files cannot be regenerated correctly.    CMakeLists.txt    /thread    MhError    CMake Problem

I am already including boost::assert's includes into my project and have them specified in the project's include path.

the error message is saying that one of boost_thread's dependencies cannot be found.

Target "boost_thread" links to:
Boost::assert
but the target was not found.
so the target "boost_thread" links to the target "boost::assert" and it could not be found

I added boost::assert both to the build path and included its includes

Let me amend my original post to include that information

[drifting pecan]

and have them specified in the project's include path
its the cmake target boost_thread that cannot find boost_assert. not your project

ok, i dont use cmake much. just install it via vcpkg and all works.

what does your cmakelists look like? are you using find_package(Boost REQUIRED COMPONENTS thread system) or the like?

all you should need in your cmakelists file is something like the following:

find_package(Boost_Thread REQUIRED)
add_executable (blah "blah.cpp" "blah.h")
target_link_libraries(blah Boost::thread)
(depending on how you have set things up)

I will check it out in the morning. I really appreciate the guidance. I will let you know how it goes 🙂

Thank you! I got that part working. I still have more compile errors, but your advice helped me solve this problem. I looked into the target_link_libraries and added those to the includes path as well as set them as project references and it worked. I really appreciate your assistance!
