Dear autoconf developers,
in a software package I have found code like this:
FOO_DIR="${bindir}"
AC_SUBST(FOO_DIR)
AC_DEFINE_UNQUOTED(FOO_DIR, "$FOO_DIR",
[Directory where foo files are installed])
The problem with that is that the value of bindir is usually
'${prefix}/bin', so the above code leads to the following line in config.h:
#define FOO_DIR "${prefix}/bin"
Since the C preprocessor does not know about variable expansion, this
reference will never be resolved, and as a result, the programs will not
find the files.
What is the most elegant way of solving this? One way I could imagine is
to drop the AC_DEFINE_UNQUOTED line and reintroduce the line via
AM_CPPFLAGS = -DFOO_DIR="@FOO_DIR@"
Is that the preferred solution?
Thanks,
Roland
