How to I tell RStudio not to ignore the indication to use clang in Makevars?

问题

以下是翻译后的内容：

我在 `Makefile` 中有这个：

PKG_CC = clang-15
PKG_CXX = clang++-15
PKG_CXXFLAGS = -g -O0 -fopenmp
PKG_LIBS = $(SHLIB_OPENMP_CXXFLAGS)
CXX_STD = CXX11
PKG_CPPFLAGS = -UDEBUG -g


当我运行 `devtools::install()` 时，我看到 `g++ -std=gnu++11 -I"/usr/share/R/include"...` 而不是我期望的 `clang...`，因为下一个测试起作用了：

```R

> pkgbuild::check_build_tools(debug = TRUE)
尝试编译一个简单的 C 文件
运行 /usr/lib/R/bin/R CMD SHLIB foo.c
使用 C 编译器：‘Ubuntu clang version 15.0.7’
clang-15 -I"/usr/share/R/include" -DNDEBUG       -fpic  -g -O2 -ffile-prefix-map=/build/r-base-JhpCKt/r-base-4.3.0=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2  -c foo.c -o foo.o
clang-15 -shared -L/usr/lib/R/lib -Wl,-Bsymbolic-functions -flto=auto -ffat-lto-objects -flto=auto -Wl,-z,relro -o foo.so foo.o -L/usr/lib/R/lib -lR
 
你的系统已准备好构建软件包！

到目前为止，我删除了 .Rproj.user 并尝试了

devtools::clean_dll()
devtools::document()
devtools::install()


<details>

I have this in `Makefile`

PKG_CC = clang-15
PKG_CXX = clang++-15
PKG_CXXFLAGS = -g -O0 -fopenmp
PKG_LIBS = $(SHLIB_OPENMP_CXXFLAGS)
CXX_STD = CXX11
PKG_CPPFLAGS = -UDEBUG -g


When I run `devtools::install()`, I see `g++ -std=gnu++11 -I&quot;/usr/share/R/include&quot;...` instead of `clang...`, which I expect because the next test worked:

```R

&gt; pkgbuild::check_build_tools(debug = TRUE)
Trying to compile a simple C file
Running /usr/lib/R/bin/R CMD SHLIB foo.c
using C compiler: ‘Ubuntu clang version 15.0.7’
clang-15 -I&quot;/usr/share/R/include&quot; -DNDEBUG       -fpic  -g -O2 -ffile-prefix-map=/build/r-base-JhpCKt/r-base-4.3.0=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2  -c foo.c -o foo.o
clang-15 -shared -L/usr/lib/R/lib -Wl,-Bsymbolic-functions -flto=auto -ffat-lto-objects -flto=auto -Wl,-z,relro -o foo.so foo.o -L/usr/lib/R/lib -lR
 
Your system is ready to build packages!

So far I deleted .Rproj.user and tried

devtools::clean_dll()
devtools::document()
devtools::install()

以下是您要翻译的内容：

您可以忽略这里的所有devtools调用，以及所有对RStudio的引用：这些只是额外的层。_一切_最终都会调用R CMD INSTALL，因此您可以直接使用它。

简而言之，您的文件可能具有错误的变量。以下是一个最小的示例（作为我用来在gcc和clang之间切换的实际子集）

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

我使用CLANGVER，因为Ubuntu通常会给我选择，而我使用VER来表示gcc。通常设置CCACHE（为ccache），但您也可以在没有它的情况下使用，如下所示在包的完整日志中：

总之，您使用了错误的变量。它们在我们必须在包和它们的src/Makevars中使用的变量之间存在差异，以及进入~/.R/Makevars的变量。这里没有前缀PKG_，'全局'变量会覆盖R在其自己的$RHOME/etc/Makeconf中的变量。

英文:

You can ignore all devtools invocations here as well as all references to RStudio: these are just added layers. Everything eventually calls R CMD INSTALL so you can this directly.

In short, you file may have the wrong variables. Here is a minimal one (as an actual subset of mine which I use to switch between gcc and clang)

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

I use CLANGVER as Ubuntu usually gives me a choice, and I use VER for gcc. CCACHE is usually set (to ccache) but you can use it without it too as shown in the full log from a package here:

edd@rob:~/git/rcppexamples(master)$ ./cleanup; install.r   # install.r wraps R CMD INSTALL

So in short you used the wrong variables. They differ between what we have to use in packages and their src/Makevars and what goes into ~/.R/Makevars. No prefix PKG_ here, the 'global' one overrides what R has in its own $RHOME/etc/Makeconf.
