Hi all,

Hello Truong,
When I tried the tutorial how to build Genode for Linux, I have an error :
In file included from /home/lbtruong/genode.11/base-linux/src/base/ipc/ipc.cc:21: /home/lbtruong/genode.11/base-linux/src/platform/linux_syscalls.h: In function ‘int lx_socketcall(int, long unsigned int*)’: /home/lbtruong/genode.11/base-linux/src/platform/linux_syscalls.h:82: erreur: ‘__NR_socketcall’ was not declared in this scope
Genode's syscall bindings for Linux include the host-system's Linux headers containing the syscall opcodes (the definitions are prefixed with SYS_). Those definitions are mapped to __NR_-prefixed defines in '/usr/include/bits/syscall.h'. According our you output, so far, everthing seems to be fine.
On 32-bit Ubuntu Linux, those names are then defined in '/usr/include/asm/unistd_32.h'. For some reason, this last step seems to go wrong on your Linux distribution.
Which Linux distribution are you using? Do you have the Linux kernel headers installed (I assume yes because the compiler does not complain about missing them)?
You could help to resolve the issue by posting result of a grep for '__NR_socketcall' in '/usr/include':
grep -r __NR_socketcall /usr/include
If you see a line containing something like the following
#define __NR_socketcall 102
Could you please tell us the name of the header file where is definition is found on your platform?
Thanks Norman
Hi Norman,
Thanks for your rapid response.
I'm sorry, I forgot to mention my distribution is Ubuntu 11.04.
with grep -r __NR_socketcall /usr/include , I see :
/usr/include/i386-linux-gnu/asm/unistd_32.h:#define __NR_socketcall 102

Hello Truong,
ok, now that makes sense. On Ubuntu 11.04, the includes have moved to the 'i386-linux-gnu' subdirectory. When compiling components that use the Linux syscall bindings, we tell the compiler to use the standard include search locations. This works because the Genode tool chain is actually a Linux tool chain. However, at the time when the Genode tool chain was built, those standard include paths did not comprise the 'i386-linux-gnu' subdirectory. So this directory is not searched for includes.
There is a quick fix and a real fix for this problem. The quick fix is the patch attached to this email. The patch adds the new include search location manually to the search paths. Could you please give it a try? If it works for you, I will commit it to our public SVN. If it does not work, could you please post the lines of the log preceding the actual error message?
The real fix would be to use a non-Linux tool chain in the first place and let the Genode build system handle the include-search paths explicitly (rather than relying on gcc's built-in heuristics). This is one topic I am currently working on. I expect that the tool chain will become part of the next release scheduled for November.
Best regards Norman
Hi Norman,
I'm sorry but it doesn't work. My distribution is a French version. So you may have somme difficult to understand the log.

thanks a lot! This log was of great help.

The actual problem is the absence of the '/usr/include/asm/' directory. The attached patch adds the new location at the places where needed. However, this should just be an interim fix. Please expect a clean solution in our SVN mid next week.
I hope, the new patch works for you.

Hello Truong,
thank you for testing the patches so quickly. Now I can construct a clean fix.
BTW, please excuse my naive question but what is the correct (and polite) way to refer to your first name. Is it Truong, or Le Bao, or TRUONG? I ask because I want to avoid embarrassing you with greeting you in each mail in a wrong way. .-)

Hello Le Bao,
now I have committed a much better solution to the SVN. Instead of duplicating in the 'i386-linux-gnu' paths at several places, the handling of hybrid Linux/Genode applications is now taken care of by the 'syscall' and the new 'lx_hybrid' libraries.
Maybe you would like to give the current SVN version a try?
Cheers Norman
Hi Norman,
Thanks for the good information. I will check it out.
