[sane-devel] Building backends on FreeBSD?

[Torfinn Ingolfsen]

Ok, I remembered to look at the FreeBSD port, and check how things are
done there. Now I'm using this configure line:
tingo at kg-core1$ MAKE=gmake CPPFLAGS=-I/usr/local/include
LDFLAGS=-L/usr/local/lib ./configure --disable-locking
--enable-pthread --without-api-spec --without-systemd BACKENDS="epson2
plustek"

unfortunately, gmake still wants to build other backends (yes, I have
done 'gmake clean' first):
cc -DHAVE_CONFIG_H -I. -I../include/sane  -D_REENTRANT
-DPATH_SANE_CONFIG_DIR=/usr/local/etc/sane.d
-DPATH_SANE_DATA_DIR=/usr/local/share
-DPATH_SANE_LOCK_DIR=/usr/local/var/lock/sane       -DV_MAJOR=1
-DV_MINOR=0 -I. -I. -I../include -I../include  -I/usr/local/include
-Wall -Wextra -pedantic -g -O2 -MT ../backend/umax_pp_low.o -MD -MP
-MF $depbase.Tpo -c -o ../backend/umax_pp_low.o
../backend/umax_pp_low.c &&\
mv -f $depbase.Tpo $depbase.Po
../backend/umax_pp_low.c:1174:4: error: use of undeclared identifier 'found'
          found = 0;
          ^
../backend/umax_pp_low.c:1175:4: error: use of undeclared identifier 'fd'
          fd = open (name, O_RDONLY);
          ^
../backend/umax_pp_low.c:1176:8: error: use of undeclared identifier 'fd'
          if (fd < 0)
              ^
../backend/umax_pp_low.c:1194:34: error: use of undeclared identifier 'fd'
              sanei_umax_pp_setparport (fd);
                                        ^
4 errors generated.

not sure how to fix this, as the (FreeBSD port) patch for this backend
already is in the source file, as far as I can see.
