每当我在Release中构建代码时,它都会编译并运行正常。但是,当我切换到Debug时,我得到一些我似乎无法弄清楚的错误。

我正在使用SWIFT和OPCODE库。我在C ++中有“运行时库”字段 - &gt;代码生成对于所有3个项目(我的主项目,swift,操作码)都是相同的。我已经尝试将它们全部设置为\ MT,并将所有设置为\ MD for Debug模式,但都不起作用。实际上,当它在Release中成功构建时,我必须将Opcode和我的活动项目设置为\ MD(swift可以是\ md或\ mt,它仍然构建)。我不太了解运行时库以便很好地链接...所以如果这是问题,你可以尝试明确吗?
我也去寻找_ITERATOR_DEBUG_LEVEL,但找不到它。我应该在哪里找到它来改变它?我在源头的任何地方都找不到它。我没有在项目属性中看到它,但是我只是没有找到属性中的正确位置,这是完全合理的。
显然,人们对错误匹配的字符集有类似的错误。我已经尝试将它们全部设置为多个并且全部设置为unicode。这似乎没有任何影响。
目前,我的活动项目只有swift.lib作为附加依赖项。我有opcode.dll和opcode_d.dll所以我没有静态链接那些。
在C / C ++设置下的预处理器中,我有以下预处理器定义:
操作码:
WIN32
_DEBUG
_WINDOWS
_USRDLL
OPCODE_EXPORTS
(SWIFT):
_DEBUG
WIN32
_LIB
LOOKUP_TABLE_5_625
活动项目:
WIN32
_DEBUG
_CONSOLE
如果需要,我可以提供更多信息。谢谢你的帮助。
答案 0 :(得分:0)
听起来您已经确保C运行时库(CRT)对所有项目都是一致的,这是首选做法。它对你的DLL项目来说不那么重要,因为它使用了CRT的独立副本。
下一步是查看项目设置的“预处理器”页面。您正在寻找可能在三个项目中发生冲突的预处理器(宏)定义。我相信你会在该列表中找到_ITERATOR_DEBUG_LEVEL。
我不知道如何在StackOverflow上发布后续问题,但您可以在您的问题中添加您在每个项目中找到的宏定义。
