Summary: some library packages always attempt to build shared libraries

Details:

Build some libs will fail with crt1.o error.

The problem happens for lib bitvector with flat format. FDPIC is ok.

Follow-ups

lib bitvector also has such fail in shared-flat format.

--- Yi Li 2009-06-05 05:44:44

Cannot reproduce pcre:

Here is what I got:

/bin/bash ./libtool --tag=CC --mode=link bfin-uclinux-gcc -pipe -Wall -g -O2

-mcpu=bf537-0.2 -version-info 0:1:0 -Wl,-elf2flt -mcpu=bf537-0.2 -o

pcre_maketables.lo pcre_newline.lo pcre_ord2utf8.lo pcre_refcount.lo

pcre_study.lo pcre_tables.lo pcre_try_flipped.lo pcre_ucd.lo pcre_valid_utf8.lo

pcre_version.lo pcre_xclass.lo pcre_chartables.lo

mkdir .libs

bfin-uclinux-ar cru .libs/libpcre.a pcre_compile.o pcre_config.o

pcre_dfa_exec.o pcre_exec.o pcre_fullinfo.o pcre_get.o pcre_globals.o

pcre_version.o pcre_xclass.o pcre_chartables.o

bfin-uclinux-ranlib .libs/libpcre.a

Fixed the others.

For pcre, svn trunk is updated to newer version and build well for FLAT. So

update the branch with newer version of pere too.

--- Vivi Li 2009-08-20 05:31:19

libnl still fails to build for flat format.

When I build pcre, if zlib is not selected in advance, it will fail to build

pcre. It lacks the dependency of pcre on zlib.

Summary for above libs after verify:

lib bitvector is ok;

lib ldap needs uclibc full version for locale lib and it can be built now;

lib pcre has dependency problem with zlib;

nllib still has the bug of crt1.o, needs to fix.

--- Yi Li 2009-08-21 00:39:31

Fixed above lib pcre and libnl issue.

--- Vivi Li 2009-09-28 00:16:41

OK on both branch and trunk. Close it.
