I had to add a few other dependencies for azure-storage-cpp, such as cpprestsdk, libxml2, iconv, openssl, but I'm still getting these unresolved symbols:

Perhaps similar to facebook/KVOController#65?

you do not have enough symbol libraries for the specified architecture

symbol __llvm***

libraries libazurestorage.a

object cloud_***

when building add the necessary code or remove dependencies for your project links to this code

http://logan.tw/posts/2015/04/28/check-code-coverage-with-clang-and-lcov/

add --coverage option

fferri commented 5 years ago

Adding coverage flags (e.g. via add_definitions(-fprofile-arcs -ftest-coverage) and link_libraries(--coverage)) doesn't help

PhoebeHui commented 4 years ago

This issue hasn’t been updated in a year; if it is still an issue, please reopen.

So what's the solution for this
