怎样处理“error C2220: warning trea...”错误

怎样处理“error C2220: warning trea...”错误

最近在编译libMXF开源库时，出现了“error C2220: warning treated as error - no 'object' file generated”错误，编译环境为VS2010，libMXF版本为1.0.0。

本文介绍解决办法。

编译时，出现的错误信息如下：

1>d:\temp\libmxf-src-1.0.0\libmxf\lib\mxf\mxf_utils.c(265): error C2220: warning treated as error - no 'object' file generated

产生原因为：SDK中的solution文件是用VS2003.net产生的，我的VS版本为VS2010，转换后，有些Project编译选项中，Treat Warnings As Errors（把警告看作错误来处理）选项开启了。

只要把此选项关闭，就可以正常编译了。

在Solution中，选择libMXF工程，右键菜单中选择“Properties”。弹出的属性框中，将Configuration选择“All Configurations”，选择“C/C++/General/”，右侧Treat Warnings As Errors值从原来的“Yes(/WX)”改为“No(/WX-)”。

点击确定，再重新编译，即可。
