Do you have a Makefile in the directory yourPackage/src/libmseed?
If so, how does it call 'ar' or '$(AR)'?

Thank you for your response. I apologize for asking basic questions, but I?m new to this. On my local machine (mac osx) the $R_HOME/etc/Makeconf AR=ar and $BINPREF is not set. I have ar in my path.

I?m uploading the package to http://win-builder.r-project.org/ using devtools::build_win. Am I right in thinking the path in question is on the Windows machine? I don?t have access to the Windows Makeconf file, so do I need to set something in the Makevars.win file?

I tried adding this to the src/Makevars.win file:
AR=$(BINPREF)ar

Then I tried:
BINPREF=/mingw_$(WIN)/bin/
AR=$(BINPREF)ar

And:
BINPREF=d:/Compiler/gcc-4.9.3/mingw_32/bin/
AR=$(BINPREF)ar

None of these changed the win-builder results. Do I have the wrong path or is Makevars.win the wrong place to set this?

Thanks,
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

  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.

It's just what it said:  you don't have ar on your path.  Normally the $(AR) variable is set to $(BINPREF)ar.  Perhaps you've changed R_HOME/etc/Makeconf so that isn't true, or have overridden BINPREF with a value different from the default.
