使用MySQL Connector C ++構建程序時出錯

Question

我有以下編譯時錯誤我找不到原因：

fatal error: mysql_connection.h: No such file or directory

我正在使用cmake，這些是CMakeLists.txt文件：

# Top level CMakeLists.txt - MyProg

cmake_minimum_required (VERSION 2.6)
set (PROJECT_NAME "MyProg")

### Out-of-tree directories
set (UTILITIES_DIR "~/utilities")

### Configure header file to pass CMake's settings to the source code
configure_file (
    "Config.h.in"
    "${PROJECT_SOURCE_DIR}/Config.h"
    )

add_subdirectory (src "${CMAKE_CURRENT_BINARY_DIR}/obj")
add_subdirectory (${UTILITIES_DIR} "${CMAKE_CURRENT_BINARY_DIR}/obj/external/utilities")

和

# Source level CMakeLists.txt - MyProg/src

### MySQL Connector/C++ ###

set (MYSQLCONNECTORCPP_ROOT_DIR "~/3rdParty/mysql-connector-c++-1.1.0")

### Include paths ###

include_directories (${CMAKE_CURRENT_SOURCE_DIR})
include_directories (${UTILITIES_DIR})
include_directories (${MYSQLCONNECTORCPP_ROOT_DIR})
include_directories (/usr/local/include)

link_directories (/usr/local/lib)
link_directories (${MYSQLCONNECTORCPP_ROOT_DIR}/driver)
link_directories (/usr/lib64/mysql/)
link_directories (/usr/lib64/)
link_directories (/usr/local/mysql/lib/)

add_executable (myprog
    entrypoint.cpp
    MyProg.cpp
    MyProg_test.cpp
    ${UTILITIES_DIR}/DBInterface.cpp
    )

target_link_libraries (myprog mysqlcppconn-static mysqlclient)

這是cmake的輸出（源代碼構建之外）：

> cmake ../MyProg/

-- Build files have been written to: ~/MyProg_prj/Debug

這是我從make得到的致命錯誤：

> make
Scanning dependencies of target myprog
[  8%] Building CXX object obj/CMakeFiles/myprog.dir/entrypoint.cpp.o
In file included from ~/MyProg_prj/MyProg/src/entrypoint.cpp:18:0:

make[2]: *** [obj/CMakeFiles/myprog.dir/entrypoint.cpp.o] Error 1
make[1]: *** [obj/CMakeFiles/myprog.dir/all] Error 2
make: *** [all] Error 2

mysql_connection.h文件位於CMakeLists.txt文件中指定的目錄中。

我升級Linux（在它正常工作之前）發生了這個問題，但這不應該是原因。 PATH應包含所需的一切。

謝謝。

平台：Linux（OpenSuse），GCC 4.7.1，cmake，MySQL Connector C ++ 1.1.0

Answer 1

您很可能錯過了'libmysqlcppconn-dev'庫。 安裝后，您不應該看到此錯誤。

Answer 2

在更新系統之前，我在源代碼中包含了MySQL標頭，如下所示：

#include <mysql_connection.h>

現在我必須指定子目錄：

#include <driver/mysql_connection.h>

路徑設置方式必須改變...
