A common problem on some systems seems to be that configure detects zlib
but then on link this error is reported (for example on IRIX):
ld32: ERROR 33: Unresolved text symbol "compress2" -- 1st referenced by
./.libs/libswishindex.al(docprop_write.lo). Use linker option -v
to see when and which objects, archives and dsos are loaded.
ld32: INFO 152: Output file removed because of error.
compress2 is in zlib.
I'm using this in configure:
if test "$with_zlib" = "no"; then
echo "Disabling compression support"
else
AC_CHECK_HEADERS(zlib.h,
AC_CHECK_LIB(z, gzread,[
AC_DEFINE(HAVE_ZLIB,[],[Do we have zlib])
if test "x${Z_DIR}" != "x"; then
Z_CFLAGS="-I${Z_DIR}/include"
Z_LIBS="-L${Z_DIR}/lib -lz"
[case ${host} in
*-*-solaris*)
Z_LIBS="-L${Z_DIR}/lib -R${Z_DIR}/lib -lz"
;;
esac]
else
Z_LIBS="-lz"
fi]))
fi
I can see that we added some test for solaris at one point.
This problem seems to come up often and I don't really understand what's
causing it on some platforms. Isn't the point of AC_CHECK_LIB to make
sure I can link with the given library?
