[R-pkg-devel] win-builder, compiling C code, make[1]: ar: Command not found

[Gillian Sharer]

Hi,

I tried to submit a package to win-builder with C code and it won’t compile. I get this result:

  ar -crs libmseed.a fileutils.o genutils.o gswap.o lmplatform.o lookup.o msrutils.o pack.o packdata.o traceutils.o    tracelist.o parseutils.o unpack.o unpackdata.o selection.o logging.o
  make[1]: ar: Command not found
  make[1]: *** [libmseed.a] Error 127
  make[1]: Leaving directory `/cygdrive/d/temp/RtmpUvWmaH/R.INSTALL3e847db06d40/IRISSeismic/src- i386/libmseed'
  make: *** [libmseed/libmseed.a] Error 2
  Warning: running command 'make -f "Makevars.win" -f "D:/RCompile/recent/R/etc/i386/Makeconf" -f   "D:/RCompile/recent/R/etc/i386/Makevars.site" -f "D:/RCompile/recent/R/share/make/winshlib.mk"   SHLIB="IRISSeismic.dll" OBJECTS="parseMiniSEED.o"' had status 2
  ERROR: compilation failed for package ‘IRISSeismic'

It says it can’t find the command ar, which I don’t understand. This was my original Makevars.win file:

  PKG_CFLAGS=
  PKG_CPPFLAGS=-Ilibmseed
  PKG_LIBS=-Llibmseed -lmseed
  $(SHLIB): libmseed/libmseed.a
  libmseed/libmseed.a:
	@(cd libmseed && $(MAKE) static CC="$(CC)" CFLAGS="$(CFLAGS)”)
  clean:
	@(cd libmseed && $(MAKE) clean)

and I also tried it using the following with the same results:

  libmseed/libmseed.a:
	@(cd libmseed && $(MAKE) static CC="$(CC)" CFLAGS="$(CFLAGS)” AR="$(AR)")

A google search turned up nothing and a stackoverflow question has not had any responses yet. Is there something I’m missing? And is there any other relevant information I can provide? I don’t have much experience compiling C code, but it works on Mac OSX and Linux.

Thanks,
