使用Artful MySQL模块出错

Posted 2020-10-01

总是报错：

[email protected]:/opt# newlisp
newLISP v.10.6.0 64-bit on Linux IPv4/6 UTF-8 libffi, options: newlisp -h

> (load "/opt/mysql.lsp")

ERR: string expected in function import : libmysqlclient

结果发现是Ubuntu 12.04下安装的libmysqlclient.so的路径不正常，用 find / -name查找， 将真实路径加入到mysql.lsp文件里

;;; Find the libmysqlclient library on this system                                                                                               
(setf is-64-bit nil)
(let ((paths ‘("/usr/lib/libmysqlclient.so"
               "/usr/lib/x86_64-linux-gnu/libmysqlclient.so" ;;here
               "/usr/lib64/mysql/libmysqlclient.so"
               "/usr/local/mysql/lib/libmysqlclient.dylib"
               "/opt/local/lib/libmysqlclient.dylib"
               "/sw/lib/libmysqlclient.dylib")))

好了。载入模块成功：

> (load "/opt/mysql.lsp")
MAIN

但是连接数据库报错。原来是没有跟上newllisp 10.6.0的步伐。 如今获取最新的未測试的代码：

git clone https://gist.github.com/10490156.git

似乎可用了，详细还要等作者完毕測试。
