Cmake錯誤生成庫

我編寫簡單的Protobuf-C庫。雖然它編譯成lib中我有如下錯誤：Cmake錯誤生成庫

target_link_libraries(ArgentumTracer-native protobuf-c)

請幫我建庫。我的資料庫擺在github上repository分支發展

您需要至少分享您的CMake代碼。乍一看，它看起來像你沒有找到/正確鏈接protobuf庫。 – StAlphonzo 2015-04-03 12:55:53

我將完整的源代碼放入存儲庫中。 – 2015-04-03 17:27:50

正如我在我的評論所說，你需要使用的CMake發現的protobuf和德protobuf的庫添加到您的target_link_libraries。您確實有鏈接中明確指出的庫，protobuf-c，但這不是一個真正的傻瓜式的方法。可以肯定的是，你應該嘗試以下內容......

find_package(Protobuf MODULE) 
if(NOT PROTOBUF_FOUND) 
    message(FATAL_ERROR "-- Protobuf is required!") 
endif() 

target_link_libraries(ArgentumTracer-native ${PROTOBUF_LIBRARIES})

現在，你可以確定你有你的正確的庫。此外，如果找不到protobuf，您將知道find_package何時失敗並有機會讓CMake成爲真正的位置。
