the dde_linux26 link error

[Guanghui, Cheng]

Hello:
        i write a device driver for L4 with DDE but when i compile the server and
client code it can't link into the lib dde_linux26 with the error like this:
        ld: cannot find -ldde_linux26
        I check the files in the libdde* and there are only these files:
        libddekit.a  libdde_linux26_block.a  libdde_linux26_net.a  libdde_linux26.o.a  
libdde_linux26_sound.a
        No libdde_linux26.a but libdde_linux26.o.a instead.

        Maybe some configuation is wrong and thanks for your any suggestion.
                                                                Cheng

Hi,

just add "libdde_linux26.o" instead of "libdde_linux26" to your Makefile
and it will work. IMHO this change was made because otherwise the linker
might have some problems to find certain symbols inside the library, and
thus will refuse to link the file. But others may correct me if I am wrong.

Regards,
Andre

So, then try linking with -ldde_linux26.o ;)

Cheers,
