Hi all,
   i think we have a problem with 64bits target.
   The problem is that package create shared libraries in /usr/lib64 instead of
   /usr/lib.
   Also pkgconfig files contain path to /usr/lib64.
   So we need to find a way to package this libraries.
   A good example is openssl.
   To  compile/install  properly i have activate the extglob shell option
   ([1]http://www.linuxjournal.com/content/bash-extended-globbing)     in
   buildtool.mk:
   [2]SHELL:=/bin/bash -O extglob
   -       -chmod -R 755 $(TARGET_DIR)/usr/lib/*
   -       -$(BT_STRIP) $(BT_STRIP_LIBOPTS) $(TARGET_DIR)/usr/lib/*.so
   -       -$(BT_STRIP) $(BT_STRIP_LIBOPTS) $(TARGET_DIR)/usr/lib/engines/*.so
   +       -chmod -R 755 $(TARGET_DIR)/usr/lib*(64)/*
   +       -$(BT_STRIP) $(BT_STRIP_LIBOPTS) $(TARGET_DIR)/usr/lib*(64)/*.so
   +       -$(BT_STRIP) $(BT_STRIP_LIBOPTS)
   $(TARGET_DIR)/usr/lib*(64)/engines/*.so
   So the libraries are installed properly (some are in /usr/lib other in
   /usr/lib64).
   The problem now is the packaging:
               <File>
                   Filename    = usr/lib/libssl.so.1.0.0
                   Source      = usr/lib/libssl.so.1.0.0
                   Type        = binary
                   Permissions = 755
               </File>
               <File>
                   Filename    = usr/lib/libssl.so.0
                   Target      = usr/lib/libssl.so.1.0.0
                   Type        = link
                   Permissions = 755
               </File>
               <File>
                   Filename    = usr/lib/libssl.so
                   Target      = usr/lib/libssl.so.0
                   Type        = link
                   Permissions = 755
               </File>
   One idea that come in my mind is to create a variable (example libarch) that
   will have the value 'lib' in 32bits and 'lib64' in 64bits mode.
   So the packaging configuration file will be:
               <File>
                   Filename    = usr/$libarch/libssl.so.1.0.0
                   Source      = usr/$libarch/libssl.so.1.0.0
                   Type        = binary
                   Permissions = 755
               </File>
               <File>
                   Filename    = usr/$libarch/libssl.so.0
                   Target      = usr/$libarch/libssl.so.1.0.0
                   Type        = link
                   Permissions = 755
               </File>
               <File>
                   Filename    = usr/$libarch/libssl.so
                   Target      = usr/$libarch/libssl.so.0
                   Type        = link
                   Permissions = 755
               </File>
   What do you think about this ?
   Do you think it's a good solution ?
   Do you have another better name for the variable (instead of libarch) ?
   We can also have a variable (we need to find a name) i call it foo that will
   be empty in 32 bits mode and will have the value '64' in 64 bits mode.
   So the path will be like: Filename    = usr/lib$(foo)/libssl.so.1.0.0
   What do you prefer if you think it's the good way ?
   Also we need to find where and how the value will be set. The best will be
   in the make/toolchain/*.mk file but they are not use during packaging.
   To resolv this we can use a config file specific to a toolchain and that is
   include by the global configfile: conf/buildtool.conf
   So in conf/buildtool.conf we will have:
   ?include conf/$(Toolchain)-vars.cfg
   and in conf/i486-unknown-linux-uclibc-vars.cfg
   <EnVars>
       libarch=lib
   </EnvVars>
   and in conf/x86_64-unknown-linux-uclibc-vars.cfg
   <EnvVars>
       libarch=lib64
   </EnvVars>
   If  we  go in this way, i need to update the perl module so we can use
   variable in included filenames.
   Regards,
   Yves
