Question

我正在编译一个R包，其中包含来自第三方的.cpp源文件。要将.cpp文件编译成静态库，我正在使用Makevars.win文件（link）。我在尝试解决与并行SHLIB相关的另一个问题时偶然发现了make仅在Windows上的一种奇怪行为，这表明我在将$(SHLIB)定义为($SHLIB)的括号中放错了位置Makevars和Makevars.win文件（link）中。

长话短说，我在$(SHLIB)和($SHILB)文件中将Makevars误写为Makevars.win。更正该错误不会在Linux和OSX的计算机上给我带来任何错误，但是在Windows ($SHLIB)上可以，但是$(SHLIB)会给我以下错误：

我了解到undefined reference错误消息正在链接错误，但是我不确定为什么会收到头文件的File format not recognized错误消息。更有趣的是，当WRE文档谈论$(SHLIB)而不是($SHLIB)时，为什么在Makevars.win文件中用$(SHLIB)替换($SHLIB)的所有方法都能正常工作。实际上，该软件包通过了所有CRAN检查，直到最近($SHLIB)中的Makevars.win都在CRAN上。

任何人都可以解释为什么会发生这种情况以及如何解决现在$(SHLIB)导致的错误。我想替换代码中错误的($SHLIB)。谢谢！

您的SOURCES_*变量包含.c和.h文件的混合。 .c被.o的{{1}}替换，但是OBJECTS_SUNDIALS_ALL文件仍然存在。在构建静态库时，这些文件似乎使.h感到困惑。如果您从nm.exe变量中删除了.h文件，则SOURCES_*消息应该消失了。
