[solved]can't compile rdiff-backup, could not read symbols

==> Starting build()...
running install
running build

building 'rdiff_backup._librsync' extension

librsync built fine through AUR...i'm not sure why rdiff-backup isn't working.  i'm new to the 64bit stuff.

thanks.

Re: [solved]can't compile rdiff-backup, could not read symbols

The error message tells you to recompile librsync with the -fPIC option. Did you do that? There's probably a configure option to do that. If not, you'll need to patch the Makefile.

Re: [solved]can't compile rdiff-backup, could not read symbols

i set the variables in makepkg.conf and recompiled libsync.  rdiff still gave me the same error...

what kind of patching would i need to do to the makefile?

EDIT:
i checked the makefile for librsync, CFLAGS has a -fPIC in there.

Re: [solved]can't compile rdiff-backup, could not read symbols

in librsync PKGBUILD use this configure line:
./configure --prefix=/usr --with-pic

also add this field before the build function to do libtool slay:
options=('NOLIBTOOL')

Re: [solved]can't compile rdiff-backup, could not read symbols

we usually fix it like this:

export CFLAGS="$CFLAGS -fPIC"
export CXXFLAGS="$CFLAGS" (if needed)

put this right on top of the build section into the pkgbuild.

here's the PKGBUILD

here's the compile output for librsync

here's the compile output for rdiff-backup

i give up!
i downloaded some opensuse binary packages of rdiff-backup and modified the PKGBUILD to just extract files from the rpm.

Re: [solved]can't compile rdiff-backup, could not read symbols

stubborn as i am...i went back to get the damn thing compiling in arch64...

rm pkg src -rf
makepkg

that did it...i guess it left some crap from previous compiles or something.
