L4 env have error when compile
by wira 22 Jan '08

22 Jan '08

Hi all, I checkout the hello package and compile it with gcc and g++-3.4, and it seems fine. But after I checkout the l4env package, and compile everything back, this error appears: o/build/include/uclibc -I/home/fiasco/build/include/uclibc++ -I/home/drops/include/x86/uclibc -I/home/drops/include/uclibc -I/home/drops/include/uclibc++ -I/usr/lib/gcc/i486-linux-gnu/3.4.6/include -gstabs+ -g -O2 -fno-strict-aliasing -march=i586 -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -fno-common -fPIC -U__PIC__ -D__PIC__=1 /home/fiasco/l4/pkg/loader/lib/runtime/helper_dyn.c -o helper_dyn.s.o ==> Linking to shared libloader.s.so LD_PRELOAD=/home/fiasco/build/tool/gendep/libgendep.so GENDEP_TARGET= libloader.s.so GENDEP_BINARY=ld ld -m elf_i386 \ -o libloader.s.so -shared -T/home/fiasco/build/lib/x86_586/main_rel.ld /home/fiasco/build/lib/x86_586/crt0.s.o helper_dyn.s.o -L/home/fiasco/build/lib/x86_586/l4v2 -L/home/fiasco/build/lib/x86_586 -L/home/fiasco/build/lib -L/home/drops/lib/x86_586/l4v2 -L/home/drops/lib/x86_586 -L/home/drops/lib --whole-archive -lsemaphore.p - lthread.p -ldm_generic.p -ldm_mem.p -lslab.p -ll4env_err.p -ll4rm.p - ll4env.p -llogserver.p -lnames.p -lroot.p -lc_be_l4env_start_stop.p -lc_be_minimal_log_io.p -lc_be_simple_mem.p -lc_be_mmap.p -lc_be_mmap_util.p -luclibc_support.p -lgeneric_ts.p -lgeneric_fprov.p -lloaderif.p-ll4util_root.p - lsigma0.p --no-whole-archive -ll4sys.p -ll4util.p -ul4util_reboot -ugetopt_long /usr/lib/gcc/i486-linux-gnu/3.4.6/libgcc.a ld: cannot find -lgeneric_fprov.p make[5]: *** [libloader.s.so] Error 1 make[5]: Leaving directory `/home/fiasco/build/pkg/loader/lib/runtime/OBJ-x86_586-l4v2' make[4]: *** [/home/fiasco/build/pkg/loader/lib/runtime/OBJ-x86_586-l4v2] Error 2 make[4]: Leaving directory `/home/fiasco/l4/pkg/loader/lib/runtime' make[3]: *** [runtime] Error 2 make[3]: Leaving directory `/home/fiasco/l4/pkg/loader/lib' make[2]: *** [lib] Error 2 make[2]: Leaving directory `/home/fiasco/l4/pkg/loader' make[1]: *** [loader.lib] Error 2 make[1]: Leaving directory `/home/fiasco/l4/pkg' make: *** [pkg] Error 2 My question is, is there any different in using the 3.4 and 4.1 version of gcc/g++? It seems that the hello package compiled fine with both of the compiler version, but the l4env package have some error on my machine. Advice needed.. Thanks, karipap

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, | Sure Bjoern, here it is. Please advice me if I have made any mistakes. The error already happens when building the IDL directory, your - -client.c file is not generated at all. Dice complains idl/aes256.idl:5.27-40: error: syntax error, unexpected identifier, expecting attribute or struct Now looking at line 5, columns 27-40 of your IDL file, you use a type called aes256_context, but this type is never defined. You need to either define it inside the IDL file or import the corresponding header file.

BID-coding an encapsulate
by Lucyantie Mazalan 22 Jan '08

22 Jan '08

Hi all, I am coding my encapsulation code for my own client-server application package referring to DROPS (BID) tutorial (mine is own implementation). I managed to compile the encapsulate code of mine but encounter an undefined reference function error while compiling the client code which refers the error to the call function [xy_call( ) - generated from the idl (is in my xy-client file)]. I have certain that all of the files related were included and double checked on my call function's parameter. I have also 'make clean' my build dir and recompile. But still I receive the same error. One might think this is stupid question, but believe. It makes me crazy already. Need advice.

Re: Try to compile flips but got error..

Hi Wira, wira wrote: > Hi all, > > It seems that my machine doesnt has the same NIC model as the intel > e1000. After I compile this Flips package, can it work on my NIC too? > Is there any generic solution or driver? Mine is intel 82562EZ rev02. I would advise you that you use "flips-ore" and "ore" instead of flips-lxdrv with the integrated e1000 driver. "flips-ore" contains no hardware drivers at all, however implements a interface to access the network by using ORe, our network multiplexer. So, it is a kind of generic solution to decouple the IP stack from the network driver. ORe supports various network cards based on drivers from Linux 2.4 and 2.6, so you have here better possibilities to get your NIC running. To configure drivers go to l4/pkg/ore/server and call a make O=.. config. Bye, Alex B.
