Hello all!
I am the maintainer of a free software package for scientific data
storage: netcdf.
In order to build on AIX in 64-bit mode, I have to be able to set the
ARFLAGS, but I can't get that to work. No matter what I do, automake
ignores my ARFLAGS and just uses "cru".
I have created a minimalistic example. A single C file, small.c, with
one function, is turned into a libtool library. The configure.ac,
Makefile.am, and code file are appended to this email.
>From the info pages on Automake:
`AR' and `ARFLAGS' default to `ar' and `cru' respectively; you can
override these two variables my setting them in your `Makefile.am',
by `AC_SUBST'ing them from your `configure.ac', or by defining a
per-library `maude_AR' variable (*note Program and Library
Variables::).
However, this is not working for me. Nor is setting AM_ARFLAGS, nor
using a per-library variable. Here's how I build this:
autoreconf -i && ARFLAGS=lalala ./configure && make
Here's the build output:
make[1]: Entering directory `/home/ed/small_autotools'
/bin/sh ./libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -Wall
-g -MT small.lo -MD -MP -MF .deps/small.Tpo -c -o small.lo small.c
libtool: compile: gcc -DHAVE_CONFIG_H -I. -Wall -g -MT small.lo -MD -MP -MF
.deps/small.Tpo -c small.c -o small.o
mv -f .deps/small.Tpo .deps/small.Plo
/bin/sh ./libtool --tag=CC --mode=link gcc -Wall -g -o libsmall.la -rpath
/usr/local/lib small.lo
libtool: link: ar cru .libs/libsmall.a small.o
libtool: link: ranlib .libs/libsmall.a
libtool: link: ( cd ".libs" && rm -f "libsmall.la" && ln -s "../libsmall.la"
"libsmall.la" )
make[1]: Leaving directory `/home/ed/small_autotools
As you can see, ar is using "cru" instead of "lalala", which is what
ARFLAGS is set to. Interestingly, the Makefile does have ARFLAGS
defined:
ARFLAGS = lalala
But neither ar nor ranlib seem to be actually used in the Makefile.
but this seems to be ignored when building the library.
So what am I doing wrong here?
Thanks,
Ed
