undefined reference errors after following manual #27

Open CptCactus opened 1 year ago

CptCactus commented 1 year ago

Dear ObjectboxTeam, i tried setting up ObjectBox for c++ as told in the manual. After changing CmakeLists.txt to find the library i now keep getting undefined reference errors

This is my Cmakelists.txt

cmake_minimum_required(VERSION 3.22)
project(objectboxtest)

set(CMAKE_CXX_STANDARD 20)

include(FetchContent)
FetchContent_Declare(
        objectbox
        GIT_REPOSITORY https://github.com/objectbox/objectbox-c.git
        GIT_TAG        v0.17.0
)

FetchContent_MakeAvailable(objectbox)

include_directories(cmake-build-debug/_deps/objectbox-sync-download-src/include)

FetchContent_Declare(
        flatbuffers
        GIT_REPOSITORY https://github.com/google/flatbuffers.git
        GIT_TAG        v2.0.0
)

FetchContent_MakeAvailable(flatbuffers)

file(COPY ${CMAKE_BINARY_DIR}/_deps/flatbuffers-src/include/flatbuffers
        DESTINATION "_deps/objectbox-sync-download-src/include/")

add_executable(objectboxtest main.cpp main.h objectbox-model.h tasklist.obx.cpp tasklist.obx.hpp)

target_link_libraries(objectbox INTERFACE objectbox)

And this is the error i keep getting

Thank you very much in advance. Jonas

Can you please send me the link to the manual that you were using?

Please note that our most up to date docs are located here: https://cpp.objectbox.io/installation. Could you try once again, but following the steps from there?

I reply here because I have unresolved references as well with 0.17, though I think the Op might have a different problem. For me, the missing symbols seem all to be from the internal namespace. I'm sure my configuration is correct because it compiles and links, fine when I replace include and lib from 0.17 with those from 0.16. Environment is VS 2019, both x64 and x68 are affected. I think you might be missing the inline declaration for some functions in the internal namespace.

Sorry that it took me so long to answer here as i was on vacation. I followed the manual you sent me and checking the ObjectBox version went fine. But when i followed the first example, and try to run it, i get the following errors:
