Eduardo: Please try doing `gcc-config -l` to see what gcc profiles you have installed on your system. If you're currently using a -hardened one, try temporarily switching to non-hardened to see if that will make splashutils compile. Arpad: Please attach config.log from /var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/jpeg-6b/.
Your recommendation worked for me. I changed the gcc-config to non hardened and splashutils went in OK.
i'm also having trouble with splashutils and using a hardened gcc, is there any possibility that splashutils will work with hardened gcc at some point? i don't have a non-hardened gcc compiled right now so... thanks for your work, and please let me know if i can help you by attaching anything
The problem here is with klibc (a library that is bundled with splashutils). If you want to help, you can grab the latest klibc tarball from http://www.kernel.org/pub/linux/libs/klibc/ and see if you can compile it with a hardened gcc.
Thats my config.log below. What should i do now? swatinux jpeg-6b # cat config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. configure:538: checking for gcc configure:615: checking whether the C compiler (gcc -Wall -g -I/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/linux/include -m elf_x86_64) works configure:629: gcc -o conftest -Wall -g -I/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/linux/include -m elf_x86_64 conftest.c 1>&5 cc1: error: missing argument to "-m" configure: failed program was: #line 625 "configure" #include "confdefs.h" main(){return(0);}
Created attachment 46328 [details, diff] Added LDFLAGS clearing..
Created attachment 46329 [details] Ebuild that uses Makefile.diff
Please put the attached Makefile.diff into the files/ subdir and replace your ebuild with the one I attached and try to emerge splashutils. Let me know whether this changes anything for you.
Sorry for the late answer and thanks for the patch. Emerging splashutils now works perfectly. I'm configuring a new kernel right now. Lets see if it works ;)
Just gave splashutils with 2.6.10 a try. But same problem with hardened-gcc here (undefined references to propolice __guard and __stack_smash_handler...). Most interestingly even when I switch from hardened to plain 3.4.3 with gcc-config it still does not work (oh yes, I did source the profile, also did a re-login twice). But when I switch to gcc-3.3.4 it worked just fine - huh? %-)
Created attachment 48261 [details, diff] Patch for the ebuild file. Compiles libraries with -fno-stack-protector. The current patch and ebuild did not worked for me. I submit a new patch for the portage ebuild: If the hardened flag is detected then compiles klibc and other libraries with the -fno-stack-protector flag. Note that this makes the package "unhardened".

OK, this is getting a little complicated, with bugs reported for different GCC versions and different configs. Let's stick to a common testing scenario. If you're experiencing problems with undefined references, please do the following: 1) If you have compiled your gcc with 'hardened' USE flag, please apply the patch from Nikolaos and see if it fixes your problem. 2) If you don't use 'hardened' USE flag, do gcc-config -l and make sure you're using a non-hardened profile. If you have multiple versions of gcc installed, switch to the latest one. Then, do `echo $GCC_SPECS`. If the variable points to a hardened spec file or anything that you don't think is right, unset it (unset GCC_SPECS). It might also be a good idea to set it to "" in /etc/env.d/05gcc After you've done all that, try to emerge splashutils and let me know of the results.
But the patch from Nikolaos is for 0.9_pre10 and not for 0.9_rc1! GCC_SPECS is already set to "". After starting emerge it came to the same result. Perhaps it belongs to another problem: During compiling e.g. kmplayer I got the following result: --------------------------------------------------------------------- * This package is blocked because it wants to overwrite * files belonging to other packages (see messages above). * If you have no clue what this is all about report it * as a bug for this package on http://bugs.gentoo.org --------------------------------------------------------------------- Does this belongs to the problem?
Created attachment 48407 [details] ebuild patched with the hardened fix
Reiner & other people using _rc1 with hardened: please try the newly attached _rc1 ebuild.
Created attachment 48448 [details, diff] Warning for "unhardened" build. Yep, last ebuild with applied patch works for me and on rc1! Though, we should inform the user that the package will be built "unhardened". I am including a patch for that...
Created attachment 48552 [details] a new ebuild with the hardened fixes Please test the new ebuild. I have changed one of the lines that add -fno-stack-protector and added a warning.
With the patch of Michal it still does not work on my both computers (Notebook and Desktop): --------------------------------------------------------------------------- make[1]: Leaving directory `/var/tmp/portage/splashutils-0.9_rc1/work/miscsplashutils-0.1.2/fbtruetype' MAKE klibc tests/environ.o(.text+0x1d): In function `main': tests/environ.c:6: undefined reference to `__guard' tests/environ.o(.text+0xa0):tests/environ.c:24: undefined reference to `__guard' tests/environ.o(.text+0xb4):tests/environ.c:24: undefined reference to `__stack_smash_handler' libc.a(__static_init.o)(.text+0x19): In function `__libc_init': /var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/libc_init.c:35: undefined reference to `__guard' libc.a(printf.o)(.text+0x16): In function `printf': /var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/printf.c:11: undefined reference to `__guard' libc.a(printf.o)(.text+0x40):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/printf.c:19: undefined reference to `__stack_smash_handler' libc.a(vfprintf.o)(.text+0x1c): In function `vfprintf': /var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/vfprintf.c:13: undefined reference to `__guard' libc.a(vfprintf.o)(.text+0x61):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/vfprintf.c:26: undefined reference to `__guard' libc.a(vfprintf.o)(.text+0x73):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/vfprintf.c:26: undefined reference to `__stack_smash_handler' libc.a(fwrite.o)(.text+0x1c): In function `_fwrite': /var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/fwrite.c:10: undefined reference to `__guard' libc.a(fwrite.o)(.text+0x6a):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/fwrite.c:32: undefined reference to `__guard' libc.a(fwrite.o)(.text+0x7f):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/fwrite.c:32: undefined reference to `__stack_smash_handler' libc.a(puts.o)(.text+0x15): In function `puts': /var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/puts.c:8: undefined reference to `__guard' libc.a(puts.o)(.text+0x4d):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/puts.c:13: undefined reference to `__guard' libc.a(puts.o)(.text+0x5f):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/puts.c:13: undefined reference to `__stack_smash_handler' libc.a(vsnprintf.o)(.text+0x26): In function `format_int': /var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/vsnprintf.c:47: undefined reference to `__guard' libc.a(vsnprintf.o)(.text+0x2e1):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/vsnprintf.c:159: undefined reference to `__stack_smash_handler' libc.a(vsnprintf.o)(.text+0x30d): In function `vsnprintf': /var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/vsnprintf.c:163: undefined reference to `__guard' libc.a(vsnprintf.o)(.text+0x7b5):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/vsnprintf.c:433: undefined reference to `__guard' libc.a(vsnprintf.o)(.text+0x7ca):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/vsnprintf.c:433: undefined reference to `__stack_smash_handler' libc.a(fputs.o)(.text+0x1d): In function `fputs': /var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/fputs.c:13: undefined reference to `__guard' libc.a(fputs.o)(.text+0x56):/var/tmp/portage/splashutils-0.9_rc1/work/splashutils-0.9-rc1/libs/klibc-0.179/klibc/fputs.c:15: undefined reference to `__stack_smash_handler' libc.a(__udivdi3.o)(.text+0x16): In function `__udivdi3': libgcc/__udivdi3.c:11: undefined reference to `__guard' libc.a(__udivdi3.o)(.text+0x3d):libgcc/__udivdi3.c:13: undefined reference to `__stack_smash_handler' libc.a(__umoddi3.o)(.text+0x16): In function `__umoddi3': libgcc/__umoddi3.c:11: undefined reference to `__guard' libc.a(__umoddi3.o)(.text+0x45):libgcc/__umoddi3.c:16: undefined reference to `__stack_smash_handler' libc.a(__udivmoddi4.o)(.text+0x1a): In function `__udivmoddi4': libgcc/__udivmoddi4.c:5: undefined reference to `__guard' libc.a(__udivmoddi4.o)(.text+0xcc):libgcc/__udivmoddi4.c:32: undefined reference to `__stack_smash_handler' make[1]: *** [tests/environ] Error 1 make: *** [klibc] Error 2 !!!

I've to correct myself: it worked on my desktop but not on my notebook. :-?
Reiner: could you please try it with the ebuild labeled 'ebuild patched with the hardened fix' on the machine on which the latest ebuild fails? Nikolaos: could you please try the latest ebuild and let me know whether it works for you just as well as the previous one did?
Michal: Przepraszam! Sorry! I don't know what to say... but on my notebook I forgot to copy your ebuild. After recognizing it I tried again and it worked. Now I've a problem with updateing kplayer... :-(
OK! Works perfectly for me. We can, if you agree, close the bug and update the portage tree.
I've just added the fix to CVS, closing.
Please don't make the stripping/negating of -fstack-protector conditional on USE=hardened. Many people, including me, use the -fstack-protector on otherwise standard systems and get caught by this.
Fixed in CVS. Thanks for the suggestion.
