build-rdup-on-osx.txt

I managed to build rdup on OSX by performing the following steps.
I don't use rdup-tr so haven't bothered to figure out how to build it.

I'm sure there is a better way to do this, but I'm not familiar enough with C or the configure/make ecosystem to know how.

1. Install glib (eg from homebrew)

2. git clone

3. autoreconf

4. ./configure; make clean; make at this step will result in this error:

crawler.c: In function ‘dir_crawl’:
crawler.c:127: error: ‘DIR’ has no member named ‘dd_fd’
make: *** [crawler.o] Error 1

To fix, I forced the use of dirfd in crawler.c: (line ~ 124)

/*ifdef HAVE_DIRFD */
	if (fstat(dirfd(dir), &s) != 0) {
/*else
	if (fstat(rdup_dirfd(dir), &s) != 0) {
endif*/

5. ./configure; make clean; make at this step will result in this error:

In file included from entry.c:8:
rdup-tr.h:35:21: error: archive.h: No such file or directory
rdup-tr.h:36:27: error: archive_entry.h: No such file or directory
make: *** [entry.o] Error 1

To fix, I forced ARCHIVE_L to be no in configure: (line ~ 4395)

# if test "x$ac_cv_lib_archive_archive_entry_copy_symlink" = xyes; then :
#   cat >>confdefs.h <<_ACEOF
# #define HAVE_LIBARCHIVE 1
# _ACEOF
# 
#   LIBS="-larchive $LIBS"
# 
# else
  ARCHIVE_L="no"
# fi

6. ./configure; make clean; make should now work.

$ ./rdup -V
