Hi, Thanks for the reply. With this email I hope to resolve my previous problems and also seek for solution of new problem. First, to respond you from previous email: | * your package dir is called aes, so all include files need to be | included through something like <l4/aes/...> Yes, previously my package name was that but I rename the archive file name to aes for your reference. But, however I am now sending to you the fixed one which all the include path is exactly same as the package name, aes. Sorry for that. | * the IDL file somehow needs to know about your aes_context type, so | either include it from a header or define it inside the IDL file - I did | so by uncommenting your stuff. Thank you, yes I have fixed it by defining the aes_context type inside the IDL file. I have also recompiled it; generate new server code and writing new same implementation in my server's functions. | And this was probably your problem: | - ---> | * The aes-client.h file should be included using | ~ #include "aes-client.h" | ~ without any directory prefixes. It is a generated header file which | ~ does not end up in the L4 include dir, but resides inside the | ~ package's IDL build dir. This is path is different from the usual | ~ include paths and is added to your compile run automatically by BID. Thank you for the information. Yes I have also fixed in my aes package file which includes the header with just a '#include "aes-client.h"', without the prefixes. However, when I compile again my client code, I still got the same error which makes me more confused of where is actually the problem is. Here I attach the pkg archive and paste the errors that I get: ---------------------------------------------------------------------------- root@lucy-ubuntu:/# cd home/fiasco/l4/pkg/aes/examples/client/ root@lucy-ubuntu:/home/fiasco/l4/pkg/aes/examples/client# make O=/home/fiasco/build/ PWD=/home/fiasco/build/pkg/aes/examples/client/OBJ-x86_586-l4v2 make -C /home/fiasco/build/pkg/aes/examples/client/OBJ-x86_586-l4v2 -f Makefile make[1]: Entering directory `/home/fiasco/build/pkg/aes/examples/client/OBJ-x86_586-l4v2' ...
