CMake找不到OCCI for C ++ Oracle应用程序 [英] CMake does not find OCCI for C++ Oracle app

问题描述

编辑：对此已经足够改变了，我打开了一个新问题。 您可以在这里找到。

Enough has changed from this that I have opened a new question. You can find it here.

我正在尝试使用OCCI使用C ++连接到Oracle 12c。我正在将CLion2016.1与受支持的Cygwin版本一起使用。 Windows7。昨天（2016年3月29日）下载了Oracle Instant Client（基本和sdk）

I'm trying to connect to Oracle 12c with C++ using OCCI. I am using CLion2016.1 with the supported version of Cygwin. Windows 7. The Oracle instant client (both basic and sdk) were downloaded yesterday (29Mar2016)

注意： C：/ Users / hunrt / libs 已添加到我的系统路径。

Note: C:/Users/hunrt/libs has been added to my system path.

我只有一个 main.cpp 文件：

#include <occi.h>

using namespace oracle::occi;

int main()
{
    Environment *env = Environment::createEnvironment(Environment::DEFAULT);
    Environment::terminateEnvironment(env);
}

如果我使用此CMake文件，则会出现以下错误。注释掉的find_library（）调用是我尝试使其工作的不同方式。我每次都收到相同的错误消息（一次只能使用一个）。

CMake文件

If I use this CMake file I get the error below. The commented out find_library() calls are the different ways I have tried to get it to work. I get the same error message with each one (I only use one at a time).
CMake file

cmake_minimum_required(VERSION 3.4)
project(Oracle)
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++14")

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)

#find_library(OCCI NAMES oraociei12.lib oci.lib orannzsbb12.lib oraocci12.lib PATHS C:/Users/hunrt/libs)
find_library(OCCI NAMES oraociei12.lib oci.lib orannzsbb12.lib oraocci12.lib PATHS /cygdrive/c/Users/hunrt/libs)

#find_library(OCCI NAMES oraociei12.lib ociw32.lib orannzsbb12.lib oraocci12.lib PATHS C:\\Users\\hunrt\\libs)



set(SOURCE_FILES
        src/main.cpp
        include/occi.h)

add_executable(Oracle ${SOURCE_FILES})
target_link_libraries(Oracle ${OCCI})

错误

Error

Error:The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
OCCI

如果我删除了find_library（）和target_link_libraries（）调用，则会收到以下错误：

If I remove the find_library() and target_link_libraries() calls then I get the following error:

我做过的其他事情尝试

我尝试将libs，dll和sym文件放入项目中，与CMakeLists.txt文件放在同一目录中，并且得到相同的错误消息。

Other things I've tried
I've tried putting the libs, dlls and sym files in the project, in the same directory as the CMakeLists.txt file and I get the same error message.

感谢您的帮助。谢谢。

Any help is appreciated. Thanks.

推荐答案

找不到库OCCI。当前，您通过的是绝对路径，这不是走的路。您应该使用 CMAKE_PREFIX_PATH 将路径添加到库。然后 find_library 将检查 CMAKE_PREFIX_PATH 中的所有路径。

The library OCCI is not found. Currently you pass an absolute path, which is not the way to go. You should add the path to the library with the CMAKE_PREFIX_PATH. Then find_library will check all paths from CMAKE_PREFIX_PATH.

对于每个图书馆oraociei12.lib，oci.lib，orannzsbb12.lib和oraocci12.lib，您都必须自己使用find_library。

For each of your libraries oraociei12.lib, oci.lib, orannzsbb12.lib, oraocci12.lib you have to usa a find_library for its own.

这篇关于CMake找不到OCCI for C ++ Oracle应用程序的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
