Are you sure? I'm sorry,I have made a mistake.Yes,the l4x_dispatch_suspend is surely no empty,it may be some error of gcc to compile the inline function,I search the error message from the Internet,they says the problem might be that a function was declared with two different inlining attributes.So,I think it maybe the gcc's matter,but after I re-install the gcc-3.4.6 and compile the l4linux-2.6.22,the some error massage appearing,so I don't know why,maybe it have something to do with another compiler enviroment,but I don't know what.

roottask problem?? help!!!
by huang 04 Sep '07

04 Sep '07

hi,dear all: When I tried to use the l4env nameserver "names" to help doing sth, I found it doesn't work. For example, the logserver "log" can not register at nameserver, so it fall asleep, so does names_demo. I examed and tested the names.c, and I modified a few lines of code in main() such as: ... if(rmgr_init()) printf("roottask service unavailable!\n"); else printf("roottask service init successfully!\n"); ... then I rebuilded names, and tested again with modules listed in menu.lst: title hello world kernel (hd0,0)/fiasco/bootstrap modaddr 0x02000000 module (hd0,0)/fiasco/fiasco -nokdb -nowait module (hd0,0)/fiasco/sigma0 module (hd0,0)/fiasco/roottask module (hd0,0)/fiasco/names module (hd0,0)/fiasco/names_demo the output screen is in the attachement roottask.jpg, the key output is names | roottask service unavailable! Is this really caused by roottask?? In the manual tut.pdf, the menu.lst is as below: title Hi world, server version kernel (nd)/tftpboot/yourname/bin/x86_586/l4v2/bootstrap modaddr 0x02000000 module (nd)/tftpboot/yourname/bin/fiasco -nokdb -nowait module (nd)/tftpboot/yourname/bin/x86_586/l4v2/sigma0 module (nd)/tftpboot/yourname/bin/x86_586/l4vs/roottask module (nd)/tftpboot/yourname/bin/x86_586/l4v2/log module (nd)/tftpboot/yourname/bin/x86_586/l4v2/names module (nd)/tftpboot/yourname/bin/x86_586/l4v2/dm_phys module (nd)/tftpboot/yourname/bin/x86_586/l4v2/hiserver module (nd)/tftpboot/yourname/bin/x86_586/l4v2/hiclient I found the line of roottask is different from other lines in "l4vs", while others are "l4v2". What is the difference? best wishes! 　　　　　　　　huang 　　　　　　　　learnl4(a)sina.com 　　　　　　　　　　2007-09-04

Hi,everyone: When I used latest version of L4 to compile the l4linux-2.6.22,it is following error message appeared. In file included from arch/l4/kernel/arch-i386/dispatch.c:586: arch/l4/kernel/arch-i386/../dispatch.c: In function `l4x_user_dispatcher': arch/l4/kernel/arch-i386/../dispatch.c:362: sorry, unimplemented: inlining failed in call to 'l4x_dispatch_suspend': function not considered for inlining arch/l4/kernel/arch-i386/../dispatch.c:506: sorry, unimplemented: called from here make[1]: *** [arch/l4/kernel/arch-i386/dispatch.o] error 1 make: *** [arch/l4/kernel/arch-i386] error 2 so I check the function dispatch.c,the function l4x_dispatch_suspend is empty indeed.Maybe there is something wrong,but I don't know what have happened.Everyone who knows this problem please help me,thanks! The L4 and l4linux are all downloaded from svn today,and my linux distribution is ubuntu 6.06. Best Regards!

why there is no bin and lib directory under build directory after I compiled the L4
by 丁莹 04 Sep '07

04 Sep '07

Hi,everyone: I have get a tudos from svn a few days ago,but when I have compiled it,there is no bin and lib derictory under tudos/l4/build/.And In the /tudos/l4/build/include derictory ,there is only a l4 directory which containning just a one file,but all compile process are all right. Of course,when I use this L4env to compile the l4linux-2.6.21,there is a lot of error,you can seeing the error informantion from the attachment. The compiler instructor I used as follow: cd tudos make -C l4 config O=./build make -C l4 O=./build The config options I used are as same as before,so I don't know what have happened.And I used the linux distribution is slackware 10.2, gcc-3.4.6,make-3.81,bison-2.3. Everybody who knows this problem please hlep me.Thanks! Best Regards!
