为什么不Win32::ODBC找到的ODBC.dll 在Perl5.10和Cygwin?
题
我试图使用Perl ODBC连接到Microsoft SQL服务器。我的问题是,Perl5.10.0是具有一个问题,使用的Win32ODBC driver.
如果我运行Perl壳和执行这一行,我得到了错误。
use Win32::ODBC;
Can't load '/usr/lib/perl5/vendor_perl/5.10/i686-cygwin/auto/Win32/ODBC/ODBC.dll'
for module Win32::ODBC: No such file or directory at
/usr/lib/perl5/5.10/i686-cygwin/DynaLoader.pm line 201.
我已经验证了dll的文件不存在。
我已经安装的Cygwin包:
- perl(5.10.0-5)
- perl-libwin32(0.28-2)
解决方案
这似乎是一个 已知的问题.抓住 libiodbc源, ,适用以下修补、建造和安装:
diff -ub libiodbc-3.52.6/include/iodbcunix.h.orig

更新: Cygwin伙计 有一个TODO于这个问题, 但这是几个月。在情况下的等待时间太长,可以假它在此期间:
#! /bin/bash
# run from the libiodbc build directory
gcc -shared -o cygiodbc-2.dll \
-Wl,--out-implib=libcygiodbc-2.dll.a \

其他提示
我已经验证了dll的文件不存在。
你的意思是 /usr/lib/perl5/vendor_perl/5.10/i686-cygwin/auto/Win32/ODBC/ODBC.dll
存在?如果是这样,你有读取和执行的许可?
有一种意见就上述/usr/lib/perl5/5.10/i686-cygwin/DynaLoader.下午线201:
# Many dynamic extension loading problems will appear to come from
# this section of code: XYZ failed at line 123 of DynaLoader.pm.
# Often these errors are actually occurring in the initialisation
# C code of the extension XS file. Perl reports the error as being
# in this perl code simply because this was the last perl code
# it executed.
因此它似乎事情是错误的安装。你可以试试重新安装Win32::ODBC:
$ cpan Win32::ODBC
