For version 0.2-2 of my ‘precautionary’ package, I have added fast numerical routines implemented in Rust. In my DESCRIPTION file, I am “LinkingTo: cargo (>= 0.1.28)”, but fail incoming check on Win-builder as follows: https://win-builder.r-project.org/incoming_pretest/precautionary_0.2-2_20210406_142130/Windows/00install.out

Other platforms check my package just fine. Is the solution to be found in configuration of Win-builder, in my Makevars.win, or elsewhere? I have taken my Makevars.win straight from https://github.com/extendr/helloextendr/blob/main/src/Makevars.win as follows: TARGET = $(subst 64,x86_64,$(subst 32,i686,$(WIN)))-pc-windows-gnu LIBDIR = ./rust/target/$(TARGET)/release STATLIB = $(LIBDIR)/libprecautionary.a PKG_LIBS = -L$(LIBDIR) -lprecautionary -lws2_32 -ladvapi32 -luserenv all: C_clean $(SHLIB): $(STATLIB) $(STATLIB): cargo build --target=$(TARGET) --lib --release --manifest-path=./rust/Cargo.toml C_clean: rm -Rf $(SHLIB) $(STATLIB) $(OBJECTS) clean: rm -Rf $(SHLIB) $(STATLIB) $(OBJECTS) rust/target [[alternative HTML version deleted]] ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
