您可以忽略此处的所有devtools个调用以及对RStudio的所有引用:这些只是添加的层.Everything最终会呼叫R CMD INSTALL，因此您可以直接拨打.
简而言之，您的文件可能有错误的变量.下面是最小的一个(作为我的一个实际子集，我用它在gcc和clang之间切换)
CLANGVER=-15
CLANGLIB=-stdlib=libc++
CXX=$(CCACHE) clang++$(CLANGVER) $(CLANGLIB)
CXX11=$(CCACHE) clang++$(CLANGVER) $(CLANGLIB)
CXX14=$(CCACHE) clang++$(CLANGVER) $(CLANGLIB)
CXX17=$(CCACHE) clang++$(CLANGVER) $(CLANGLIB)
CXX20=$(CCACHE) clang++$(CLANGVER) $(CLANGLIB)
CC=$(CCACHE) clang$(CLANGVER)
SHLIB_CXXLD=clang++$(CLANGVER) $(CLANGLIB)
CXXFLAGS=-Wall -O3 -pedantic
CXX11FLAGS=-Wall -O3 -pedantic
CXX14FLAGS=-Wall -O3 -pedantic
CXX17FLAGS=-Wall -O3 -pedantic
CXX20FLAGS=-Wall -O3 -pedantic
我用CLANGVER，因为Ubuntu通常给我一个 Select ，我用VER代表gcc.通常设置为CCACHE(设置为ccache)，但您也可以在没有它的情况下使用它，如以下程序包中的完整日志(log)所示:

因此，简而言之，你使用了错误的变量.它们不同于我们必须在包裹中使用的内容，以及它们的src/Makevars和~/.R/Makevars中的内容.这里没有前缀PKG_，‘global’优先于R在它自己的$RHOME/etc/Makeconf中的前缀.
