I think I tried the commands in the right R session. Here are all the output related to the environment variables for R as well as Sys.which(): ``` > Sys.getenv("RTOOLS42_HOME") [1] "C:/rtools42" > Sys.getenv("RTOOLS43_HOME") [1] "C:/rtools43" > Sys.getenv("R_USER") [1] "C:\\Users\\Christophe Bousquet\\Documents" > Sys.getenv("R_RTOOLS43_PATH") [1] "C:/rtools43/x86_64-w64-mingw32.static.posix/bin;C:/rtools43/usr/bin" > Sys.getenv("R_LIBS_USER") [1] "C:\\Users\\Christophe Bousquet\\AppData\\Local/R/win-library/4.3" > Sys.getenv("R_LIBS_SITE") [1] "C:/PROGRA~1/R/R-43~1.1/site-library" > Sys.getenv("R_HOME") [1] "C:/PROGRA~1/R/R-43~1.1" > Sys.getenv("R_COMPILED_BY") [1] "gcc 12.2.0" > Sys.getenv("R_ARCH") [1] "/x64" > Sys.which("Make") Make "C:\\rtools43\\usr\\bin\\Make.exe" > Sys.which("GCC") GCC "C:\\rtools43\\X86_64~1.POS\\bin\\GCC.exe" ``` So when I run the commands, I get this output. I honestly have no clue whether this can be considered as something useful or not :-/ ``` > tools:::.shlib_internal(c('-n', 'hello.c')) make cmd is make -f "C:/PROGRA~1/R/R-43~1.1/etc/x64/Makeconf" -f "C:/PROGRA~1/R/R-43~1.1/share/make/winshlib.mk" SHLIB="hello.dll" WIN=64 TCLBIN= OBJECTS="hello.o" make would use gcc -I"C:/PROGRA~1/R/R-43~1.1/include" -DNDEBUG -I"C:/rtools43/x86_64-w64-mingw32.static.posix/include" -O2 -Wall -mfpmath=sse -msse2 -mstackrealign -c hello.c -o hello.o if test "zhello.o" != "z"; then \ if test -e "hello-win.def"; then \ echo gcc -shared -s -static-libgcc -o hello.dll hello-win.def hello.o -L"C:/rtools43/x86_64-w64-mingw32.static.posix/lib/x64" -L"C:/rtools43/x86_64-w64-mingw32.static.posix/lib" -L"C:/PROGRA~1/R/R-43~1.1/bin/x64" -lR ; \ gcc -shared -s -static-libgcc -o hello.dll hello-win.def hello.o -L"C:/rtools43/x86_64-w64-mingw32.static.posix/lib/x64" -L"C:/rtools43/x86_64-w64-mingw32.static.posix/lib" -L"C:/PROGRA~1/R/R-43~1.1/bin/x64" -lR ; \ else \ echo EXPORTS > tmp.def; \ nm hello.o | sed -n 's/^.* [BCDRT] / /p' | sed -e '/[.]refptr[.]/d' -e '/[.]weak[.]/d' | sed 's/[^ ][^ ]*/"&"/g' >> tmp.def; \ echo gcc -shared -s -static-libgcc -o hello.dll tmp.def hello.o -L"C:/rtools43/x86_64-w64-mingw32.static.posix/lib/x64" -L"C:/rtools43/x86_64-w64-mingw32.static.posix/lib" -L"C:/PROGRA~1/R/R-43~1.1/bin/x64" -lR ; \ gcc -shared -s -static-libgcc -o hello.dll tmp.def hello.o -L"C:/rtools43/x86_64-w64-mingw32.static.posix/lib/x64" -L"C:/rtools43/x86_64-w64-mingw32.static.posix/lib" -L"C:/PROGRA~1/R/R-43~1.1/bin/x64" -lR ; \ rm -f tmp.def; \ fi \ fi [1] 0 > tools:::.shlib_internal('hello.c') using C compiler: ‘gcc.exe (GCC) 12.2.0’ gcc -I"C:/PROGRA~1/R/R-43~1.1/include" -DNDEBUG -I"C:/rtools43/x86_64-w64-mingw32.static.posix/include" -O2 -Wall -mfpmath=sse -msse2 -mstackrealign -c hello.c -o hello.o gcc -shared -s -static-libgcc -o hello.dll tmp.def hello.o -LC:/rtools43/x86_64-w64-mingw32.static.posix/lib/x64 -LC:/rtools43/x86_64-w64-mingw32.static.posix/lib -LC:/PROGRA~1/R/R-43~1.1/bin/x64 -lR [1] 0 ``` > (I'm still debugging from first principles.

I think that my environment variables and paths are correct. But I did not fully understand how to adjust PATH. I already tried a few things along these lines, but it never solved my problem. And I somehow assumed that by uninstalling/reinstalling all R-related things, the paths and variables would also be reset. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
