问题描述
我尝试从node.js应用程序连接到DB2。我决定使用。安装 db2.js 的说明首先告诉您如下安装 node-gyp ：
sudo npm install -g node-gyp
对我来说。
然后我尝试用这个命令安装db2.js：
sudo npm install -g db2
然后我得到这个错误：
...
cc1plus：错误：无法识别的命令行选项-std = c ++ 0x
...
gyp ERR！ node -v v0.10.9
gyp ERR！ node-gyp -v v0.9.6
查看，它说我需要gcc。在我的系统上在gcc上做一个人显示， -std 选项只支持一些真正的旧编译器，例如 c ++ 98 4.1.2 20080704（Red Hat 4.1.2-50）， gnu99 。
所以我有几个问题。有没有另一种方法连接到db2从节点？如果我继续使用db2.js，那么我现在需要做什么，升级我的gcc或安装一个 c ++ 0x 编译器？ （我认为是C ++版本11）。
祝你好运。
编辑：
我在我的linux服务器上升级gcc时遇到问题，所以我尝试在我的树莓pi上安装测试：
sudo npm install -g node-gyp
cd / usr / lib / node_modules
sudo git clone https://github.com/herzi/db2.js.git
sudo node-gyp configure
sudo node-gyp build
得到此错误：
在从../src/binding.cc:3:0：
中包含的文件中。 ./src/connection.hh:6:20：致命错误：sqlcli.h：没有这样的文件或目录
编译终止。
我猜这是DB2客户端头文件，所以我可能还需要安装。 p>
EDIT 2
我在我的系统上安装了 gcc 一个不同的目录。然后我改变了 / usr / bin 中 gcc 和 g ++ 指向我的新gcc和g ++（在gcc内）。现在我得到了相同的 sqlcli.h 错误，我得到我的pi。获得DB2客户端的时间。
Meh。我有db2客户端9.1.2。我需要9.7根据一些搜索在db2 binding.gyp 文件。

我安装了IBM Data Server Runtime Client V9.7，但在<$ c $中没有 sqlcli.h c> /opt/IBM/db2/V9.7/include 文件夹！我有一个V9.1.3在不同的机器，有一个包含文件夹。因此，我安装了帮助我。现在我从node-gyp生成一个错误， strcmp 没有声明。我打赌我需要设置一个lib包含或节点环境var。
你可以添加包含文件的字符串函数 #include< cstring> ）转换为 src / connection.cc 。这应该启用字符串函数;也许你需要用 strcmp（）替换 std :: strcmp（）。
I am trying to connect to DB2 from a node.js application. I have decided to use the db2 node module. The instructions for installing db2.js first tell you to install node-gyp like this:
sudo npm install -g node-gyp
That seems to have worked for me.
Then I try to install db2.js with this command:
sudo npm install -g db2
Then I get this error:
...
cc1plus: error: unrecognized command line option "-std=c++0x"
...
gyp ERR! node -v v0.10.9
gyp ERR! node-gyp -v v0.9.6
Looking at the prereqs for node-gyp, it says I need gcc. Doing a man on gcc on my system shows that the -std option is only supporting some really old compilers like c++98, gnu99, etc. I have gcc version 4.1.2 20080704 (Red Hat 4.1.2-50).
So I have a few questions. Is there another way to connect to db2 from node? If I continue with db2.js, then what do I need to do now, upgrade my gcc or install a c++0x compiler? (I think that's C++ version 11).
Wish me luck.
EDIT:
I am having trouble upgrading gcc on my linux server, so I tried installing on my raspberry pi as a test:
sudo npm install -g node-gyp
cd /usr/lib/node_modules
sudo git clone https://github.com/herzi/db2.js.git
sudo node-gyp configure
sudo node-gyp build
On the last command I get this error:
In file included from ../src/binding.cc:3:0:
../src/connection.hh:6:20: fatal error: sqlcli.h: No such file or directory
compilation terminated.
I am guessing that's the DB2 Client header file, so I probably need to install that also.
EDIT 2
I installed gcc on my system in a different directory. Then I changed the symlinks in /usr/bin for gcc and g++ to point at my new gcc and g++ (inside gcc). Now I get the same sqlcli.h error that I get on my pi. Time to get the DB2 Client.
Meh. I have db2 client 9.1.2. I need 9.7 according to some searching in the db2 binding.gyp file.
EDIT 3
I installed "IBM Data Server Runtime Client V9.7", but it does not have sqlcli.h in the /opt/IBM/db2/V9.7/include folder! I have a V9.1.3 on a different machine which does have a include folder. So I installed "IBM Data Server Client 9.7" using an old blog post of mine to help me. Now I am getting an error from the node-gyp build that strcmp was not declared. I bet I need to set a lib include or node environment var.
You can add the include files for string functions (e.g. #include <cstring>) into src/connection.cc. That should enable the string functions; maybe you need to replace strcmp() with std::strcmp() then.
