我正在尝试构建rtl140.bpl的调试版本,以便更轻松地使用运行时包调试应用程序。我构建了DPK并在其上运行了DCC32,然后它就会进入,然后死掉。
C:\ Program Files(x86)\ Embarcadero \ RAD Studio \ 7.0 \ source \ Win32 \ rtl \ sys \ Variants.pas(1072)致命:F2092程序或单位'Variants'以递归方式自行使用
但是看着Variants.pas,我看不出怎么样。它只在接口部分中使用SysUtils和Types,它们都不使用Variants,也不使用任何使用Variants的东西。
有没有人知道为什么这会破坏?

这是我们(RAD Studio团队)不建议重建核心rtl包的主要原因之一。它需要非常小心地完成,并且需要按照特定顺序在包含部分中列出单元。
Variants是一个“混蛋”单位。编译器具有它的特定知识,这样当它看到使用Variant类型时,它会自动将变量添加到使用列表中,以确保存在对Variant类型的实际RTL支持。 System.pas将大多数变量操作推迟到Variants单元,但由于System不能使用除SysInit之外的任何其他单元(这也是一个非常特殊的单元),编译器必须参与其中。
目前,除了尝试重新排列.dpk中的包含列表并重试之外,我没有任何具体的建议来完成这项工作。这是我们用来构建该软件包的rtl.dpk的包含列表:

答案 1 :(得分:3)
程序或单位'Variants'以递归方式自行使用
通常是由您尝试构建的项目的库搜索路径中的source / win32 / rtl / sys路径引起的。
答案 2 :(得分:-1)
转到(Delpi_Path)\ source \ Win32 \ rtl \ sys,然后重命名" Variants.pas"对任何事情,例如" Variants.sav",然后一切都好。
这是因为德尔福无法找到" Variants.pas"现在任何地方,但它仍然可以找到一个名为" Variants.dcu"的编译后的dcu文件。在某个地方,这就是它。
P.S。如果Delphi也找不到dcu,你应该手动设置" Variants.dcu",然后在"工具 - >中添加路径。选项"菜单。
