Is there any install target that builds debug and release static libraries side by side? For instance, my use case would be to build grpc and then use cmake's $<CONFIG> parameter to select release or debug with grpc as an IMPORTED CMake target.
It looks like grpc builds the debug and release libraries with the same name. Instead of seeing grpc.lib and grpc_d.lib, they're both named grpc.lib. This means they can not coexist for the same install target through CMAKE. A quick example of this problem is to do the following actions (I'm using v1.72, but this should still be recent enough): 1) Checkout the git module and submodules for grpc. 2) navigate to the test\distrib\cpp directory 3) Run the run_distrib_test_cmake.bat batch file (noting that you'll need powershell and other things in your path for it to complete successfully). 4) Navigate to the examples\cpp\helloworld\cmake\build directory and open the HelloWorld.sln that is built by the batch file above. VS 2022 (in my case) will open the project. 5) Attempt to build using the default Debug target. It will fail. This is because grpc was built using Release above, and not debug. You will get an output similar to the following: 7>grpc++.lib(completion_queue_cc.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in greeter_async_server.obj 7>grpc++.lib(completion_queue_cc.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in greeter_async_server.obj 7>grpc++.lib(insecure_server_credentials.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in greeter_async_server.obj 7>grpc++.lib(insecure_server_credentials.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in greeter_async_server.obj 7>grpc++.lib(server_context.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in greeter_async_server.obj 7>grpc++.lib(server_context.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in greeter_async_server.obj --- Now, I understand that this is looking for Debug windows symbols that aren't in the generated Release library. I understand that the way to solve this is to build the library for Debug and not Release. The question I have, is: Is there a way to build both debug and release versions of the GRPC (and dependencies) libraries such that I can switch between Debug and Release configurations of a build without having to call CMake again to change the location of find_package(grpc CONFIG REQUIRED)? I saw a note about changing the CMakePresets.json file, and this would work to switch between two install directories of GRPC, but I want to avoid having to do this if at all possible, as it appears to be a workaround and calls CMake to configure for each build designation instead of simply using a common CMake target and switching between a CONFIG target. I apologise for the dense CMake terminology. Perhaps there is a simpler way to build the debug targets with different library names. If anybody can point me in that direction, that would be great. -- You received this message because you are subscribed to the Google Groups "grpc.io" group.
