Sorry, I did not understand youe example. I thought that you linked all obj-file in one sh-obj, and it functions off course. Now I have seen that you use the tipical "-L<path> -l<lib>" C options. I tried to do the same in my Makefile, but is does not function, and returns the following error: `libmyprint.so: cannot open shared object file: No such file or directo +ry at /usr/local/lib/perl5/5.8.7/i686-linux/DynaLoader.pm line 230.` [download] It looks like that I must tell to Perl where is my sh-object. I am tring with @dl_library_path in pm-file, but no success again... have you a suggestion for me?	[reply] [d/l]

Either you use rpath to code the path to the shared object file into helloworld.so, or you put libmyprint.so into a standard library path (/usr/lib, /lib, directories in /etc/ld.so.conf, ...) and run ldconfig afterwards, or you set the LD_LIBRARY_PATH environment variable to the path where libmyprint.so lives. As an alternative you can also build libmyprint as a static library and link it into helloworld.so as a statically. That of course depend on the vendor of the library you want to bind as it'll only work if they provide a static library. Cheers, Flo	[reply]
