Hi,
I attempted to import 'quotearg' module into an existing project tree by following the instructions on this section of the manual:
changing the existing project files
configure.ac and top Makefile.am accordingly. It seems that the 'lib' and 'm4' directories have been successfully created and the relevant files copied.
After that, I ran 'autoreconf' and attempted to build the project. The first thing I noticed is that the existing project explicitly defined _GNU_SOURCE in some source files. After importing the gnulib changes, this is now also defined in config.h too so the compiler complained about double references to the macro in the sources that explicitly defined it and also included config.h. I resolved that by removing the definition in the existing project tree source files and left the definition from config.h.
So far so good. Then I attempted to take advantage of the qutoeaf facilities provided by quotearg by including "#include "lib/quotearg.h"" in the source and adding the following definitions
/* Use these when there are spaces around the file name,
in the error message. */
#define quoteaf(arg) \
quotearg_style (shell_escape_always_quoting_style, arg)
#define quoteaf_n(n, arg) \
quotearg_n_style (n, shell_escape_always_quoting_style, arg)
borrowed from coreutils/src/system.h just to test locally if it works.
I got this compile error:
undefined reference to `quotearg_style'
I added this to the top Makefile.am (among other things):
...
AM_CPPFLAGS = -I$(top_builddir)/lib -I$(top_srcdir)/lib
...
LDADD = lib/libgnu.a
...
but it looks like no lib/libgnu.a file has been generated.
What I am missing as part of this procedure?
Thanks,
Alex
