Summary:                    libglib12 is only built as a static library
Description: 
trying to make libglib12 and it ends with error about missing libglib.so in
buildroot/build_arm/staging_dir/lib/. 

cp -dpf
/home/guru/project/original/bldrt/buildroot/build_arm/staging_dir/lib/libglib.so

In file build_i386/glib-1.2.10/ltconfig, there is a test which starts at
line 1793:
echo $ac_n "checking dynamic linker characteristics... $ac_c" 1>&6
case "$host_os" in
...

Because our $host_os is 'i386-pc-linux-gnu', I gather that the script
matches our $host_os to this:
[line 1902]
gnu*)
  version_type=linux
  need_lib_prefix=no
  need_version=no
  library_names_spec='${libname}${release}.so$versuffix
${libname}${release}.so$
  soname_spec='${libname}${release}.so$major'
  shlibpath_var=LD_LIBRARY_PATH
  ;;

I think the correct match is further below:
[line 1987]
linux-uclibc*)
  version_type=linux
  need_lib_prefix=no
  need_version=no
  library_names_spec='${libname}${release}.so$versuffix
${libname}${release}.so$
  soname_spec='${libname}${release}.so$major'
  finish_cmds='PATH="\$PATH:/sbin" ldconfig -n $libdir'
  shlibpath_var=LD_LIBRARY_PATH
  shlibpath_overrides_runpath=no
  # deplibs_check_method=pass_all
  deplibs_check_method='file_magic ELF [0-9][0-9]*-bit [LM]SB (shared
object|dy$
  file_magic_cmd=/usr/bin/file
  file_magic_test_file=`echo /lib/libuClibc-*.so`
  # This implies no fast_install, which is unacceptable.
  # Some rework will be needed to allow for fast_install
  # before this can be enabled.
  # Note: copied from linux-gnu, and may not be appropriate.
  hardcode_into_libs=yes
  # Assume using the uClibc dynamic linker.
  dynamic_linker="uClibc ld.so"
  ;;

I inserted a line right after the start of the test:
[line 1793]
echo $ac_n "checking dynamic linker characteristics... $ac_c" 1>&6
host_os=linux-uclibc
case "$host_os" in
...

After that, the package builds normally.

Hi,

when compilling libglib12, configure output says

<snip>
<snip>
<snip>

checking for /opt/arm-uclinux/usr/bin/arm-linux-uclibcgnueabi-ld
-L/opt/arm-uclinux/lib -L/opt/arm-uclinux/usr/lib
--sysroot=/opt/arm-uclinux/ option to reload object files... -r
checking dynamic linker characteristics... no
checking if libtool supports shared libraries... no
checking whether to build shared libraries... no
checking whether to build static libraries... yes
checking for objdir... .libs
creating libtool
<snip>
<snip>
<snip>

In in ltconfig file, host_os is taken as arm_linux. I placed an echo for
host_os at line 1793 in ltconfig file.

echo $ac_n "checking dynamic linker characteristics... for host $host_os
$ac_c" 1>&6
case "$host_os" in

  Here it checks for Dynamic linking characteristics of this os
(arm-linux) and hence it fails the test. So it cannot build shared
libraries. 

Can anyone shed some light on this. 

Should i add 
host_os=linux-uclibc 

or 

linux-uclibc*)
arm-linux*)                     ----> add this line. is this correct

Thanks in advance

Gururaja
