libsqlite3.dylib link with CMake

本文关键字：CMake with link dylib libsqlite3      更新时间：2023-10-16

我正在尝试使用cmake将libsqlite3.dylib与C 链接，但我一直遇到以下错误：

Undefined symbols for architecture x86_64:
  "_sqlite3_close", referenced from:
      OpnavCamera::~OpnavCamera() in opnav_camera.cpp.o
      OpnavCamera::updateState() in opnav_camera.cpp.o
  "_sqlite3_exec", referenced from:
      select_stmt(char const*) in opnav_camera.cpp.o
  "_sqlite3_open", referenced from:
      OpnavCamera::updateState() in opnav_camera.cpp.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [../modules/opnav_camera/_opnav_camera.so] Error 1
make[1]: *** [SimCode/CMakeFiles/_opnav_camera.dir/all] Error 2
make: *** [all] Error 2

在线环顾四周，看来我没有成功地链接库。我是Cmake的新手，所以我不知道自己在做什么。

我添加了以下内容到我的cmakelists.txt：

#SQLite 3
# Look for the header file.
FIND_PATH(SQLITE3_INCLUDE_DIR NAMES sqlite3.h)
# Look for the library.
FIND_LIBRARY(SQLITE3_LIBRARY NAMES sqlite3.0)
# Handle the QUIETLY and REQUIRED arguments and set SQLITE3_FOUND to TRUE if all listed variables are TRUE.
INCLUDE(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(SQLITE3 DEFAULT_MSG SQLITE3_LIBRARY SQLITE3_INCLUDE_DIR)
# Copy the results to the output variables.
IF(SQLITE3_FOUND)
  SET(SQLITE3_LIBRARIES ${SQLITE3_LIBRARY})
  SET(SQLITE3_INCLUDE_DIRS ${SQLITE3_INCLUDE_DIR})
  message( " Found ")
ELSE(SQLITE3_FOUND)
  SET(SQLITE3_LIBRARIES)
  SET(SQLITE3_INCLUDE_DIRS)
ENDIF(SQLITE3_FOUND)
set (CMAKE_SHARED_LINKER_FLAGS "-Wl,--as-needed")
MARK_AS_ADVANCED(SQLITE3_INCLUDE_DIRS SQLITE3_LIBRARIES)

cmake正在找到库，但我认为我只是错过了如何实际链接它的一步。在此处输入图像描述

我缺少什么作品？

ld: symbol(s) not found for architecture x86_64

看来，您正在构建一个64位应用程序，并试图链接到32位库。您需要链接到库的64位版本。
