Fiasco / L4Re compilation issues
by Thomas DuBuisson 01 Nov '10

01 Nov '10

All, I've never had success with Fiasco but decided to give it another go so I could run some benchmarks. In short, I had one success and two failures. Any help would be appreciated. 1) I can build Fiasco for x86 on the host (32 bit x86 system). Yay 2) Can't build Fiasco for ARM on an x86 host due to... an old arm-linux-gcc version? 3) Can't build L4Re due to linker error. 1) Successful build of Fiasco x86 This and other builds are using a recent pull from the repo [1] on a Fedora based 32bit x86 system running gcc 4.4.4 on Linux 2.6.34. 2) Failure to build Fiasco ARM This early failure seems to be a simple problem with gcc changing the arguments - can anyone tell me the version of the "official" arm compiler in use? I'm running arm-linux-gcc 3.4.4. ------------ make[1]: Entering directory `/home/tommd/dev/L4/L4Re/build_arm' ... Generating version information ... Making kip.o cc1plus: error: invalid option `abi=apcs-gnu' make[1]: *** [kip.o] Error 1 ------------- 3) Failure to build L4Re due to linker error The symbol "__stack_chk_fail_local" is missing when building "libl4util.so" (see below). A quick objdump/grep doesn't show this symbol in any object file in the build directory - is the build system slightly broken? I see the source definition but don't really want to hack around in the build system. $ ld --version GNU ld version 2.20.51.0.2-20.fc13 20091009 ------------- make[5]: Entering directory `/home/tommd/dev/L4/L4Re/build/pkg/l4util/lib/src/OBJ-x86_core2-l4f' ==> Linking to shared libl4util.so /usr/lib/gcc/i686-redhat-linux/4.4.4/libgcc_eh.a(unwind-dw2.o): In function `.L107': (.text+0xb79): undefined reference to `__stack_chk_fail_local' /usr/lib/gcc/i686-redhat-linux/4.4.4/libgcc_eh.a(unwind-dw2.o): In function `.L358': (.text+0x1a85): undefined reference to `__stack_chk_fail_local' /usr/lib/gcc/i686-redhat-linux/4.4.4/libgcc_eh.a(unwind-dw2.o): In function `_Unwind_Backtrace': (.text+0x24bf): undefined reference to `__stack_chk_fail_local' /usr/lib/gcc/i686-redhat-linux/4.4.4/libgcc_eh.a(unwind-dw2.o): In function `_Unwind_ForcedUnwind': (.text+0x26ad): undefined reference to `__stack_chk_fail_local' /usr/lib/gcc/i686-redhat-linux/4.4.4/libgcc_eh.a(unwind-dw2.o): In function `__frame_state_for': (.text+0x29e8): undefined reference to `__stack_chk_fail_local' /usr/lib/gcc/i686-redhat-linux/4.4.4/libgcc_eh.a(unwind-dw2.o):(.text+0x2b78): more undefined references to `__stack_chk_fail_local' follow ld: libl4util.so: hidden symbol `__stack_chk_fail_local' isn't defined ld: final link failed: Nonrepresentable section on output make[5]: *** [libl4util.so] Error 1 ---------------- Cheers, Thomas [1] http://os.inf.tu-dresden.de/L4Re/download.html

How to compile DDekit in l4re-snapshot-2010080920?
by 方明伟 25 Oct '10

Hi : Everyone! I am a new one to use fiasco.OC. Now, I am compiling L4Linux for X86 and arm. But I didn't know how to configure the DDekit. In "l4/pkg/dde/Makefile", three senteces are being commented. "# $(VERBOSE)PWD=$(PWD)/linux26/include $(MAKE) -C linux26/include # $(VERBOSE)PWD=$(PWD)/linux26/contrib/include $(MAKE) -C linux26/contrib/include" "# $(VERBOSE)PWD=$(PWD)/linux26/lib $(MAKE) -C linux26/lib" Does that mean I can't use the DDekit now? So I wondered can DDekit be used in L4Re? If yes, how can I configure and compile the dde in /l4/pkg?
