Static library built in VS2015 doesn't work about celero

[DigitalInBlue]

Did you compile with the CMake variable CELERO_COMPILE_DYNAMIC_LIBRARIES set to OFF? If you did, there should be a precompiler definition of CELERO_STATIC for all of your projects. When that is set, Export.h is supposed to give blank definitions to CELERO_EXPORT and CELERO_EXPORT_C. When this is true, you will not have __declspec(dllimport) used in your project, but this is exactly what I see in your log file. Check to make sure CELERO_STATIC is defined in all of your projects.

While adding CELERO_STATIC did fix _declspec(dllimport) errors, I've got a new one:

celerod.lib(Utilities.obj) : error LNK2019: unresolved external symbol CallNtPowerInformation referenced in function "void __cdecl celero::DisableDynamicCPUScaling(void)" (?DisableDynamicCPUScaling@celero@@YAXXZ)

Again, same code (from the example you provided), works with dll build.

Looks like PowrProf.lib needs to be included. (I haven't actually built with static libraries myself.)

Yes, adding PowrProf.lib fixed this issue.

Will you fix the static build or just advise against using it? Either way, I think it would be a good idea to update the README file on project's page.

[DigitalInBlue]

Great. I will update the CMakeList.txt and push the change. Thanks for the debugging help.

No problem. Thank you for creating this great library :)

Can you close this issue?

[MichaelMauderer]

Has this actually been fixed? I just ran into this issue (Visual Studio 14 2015 Win64) with the current version.

[DigitalInBlue]

Was the issue that "PowrProf.lib" was not linked or is your problem a new issue?

[MichaelMauderer]

Yeah exactly. I got it fixed for our build, but it seems that the current fix in the Celero CMake file didn't work for me.

[DigitalInBlue]

Ok. Can you push your fix up? Sorry. I don't use it statically and didn't know it was broken still.

[MichaelMauderer]

I only fixed the issue locally by adding a target_link_libraries(PROJECTNAME PowrProf.lib) to our build. I am not sure why the one from the Celero CMakeLists.txt did not do the job though.
