disable eventprofiler on Solaris gcc3, preventing core dumps #702 #572

eventprofiler patch is doing some realloc/malloc magic outside of
main core process, allocating memory in a way it will fail on
Solaris gcc3 (while gcc4 works). Made optional by compiler
detection flag.

refs #572

move eventprofiler init after config parsing, checking if enabled, making it optional all over #572 #702

Similar error on Solaris 10 (Sparc).

I did a test installation on Solaris 10: SunOS unknown 5.10 Generic_141445-09 i86pc i386 i86pc

I used gcc4 from blastwave.org to compile icinga i can not reproduce this problem.

Which compiler did you use?

[icinga-migration]

Updated by dilbret42 on 2010-07-31 14:22:30 +00:00

For Solaris 10 (Sparc) I used the version of gcc3 included with Sun Studio 12

[icinga-migration]

Updated by Meier on 2010-07-31 16:06:06 +00:00

Hm I did install Sun Studio 12 and i can't find any included gcc there. Compiling with the suncc fails because of https://dev.icinga.org/issues/521

Hi Meier,

There is no gcc in Sun Sudio 12. Sun Studio 12 includes its compiler. Basically we need to install gcc package on Solaris. We may install gcc package by different providers like SUNWgcc, SMCgcc etc.

The core dump happens on my following platform:
Generic_127112-10 i86pc i386 i86pc Solaris
bash-3.00# gcc -v
Reading specs from /usr/local/lib/gcc/i386-pc-solaris2.10/3.4.6/specs
Configured with: ../configure --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld --enable-shared --enable-languages=c,c**,f77
Thread model: posix
gcc version 3.4.6

BTW.The beta version icinga-1.0.1 works on my previous platform. So far this version is working on my platform and no issue is found so far.

Thanks,

I really shouldn't reply to emails in the morning without a Mtn Dew first. GCC3 came from sunfreeware.com. As another point of information I was able to compile and run the last release version just fine on the same box.

Updated by Meier on 2010-08-12 19:20:01 +00:00

dilbret42: Hm the last release version 1.0.2, but that is also the version you reported the problem against.

kimige: which icinga is NOT working for you? can you test if a build with a different compiler changes anything?

[icinga-migration]

Updated by dilbret42 on 2010-08-13 02:05:44 +00:00

By last release I meant 1.0.1

Updated by kimige on 2010-08-13 07:47:06 +00:00

Hi Meier,
The version 1.0.2 is not working for me. But the version 1.0.1 works.

let me try it with a different compiler and will let you know the result.

Thanks

I am also seeing the SIGBUS error here on SPARC64. Do you need any additional information to get this problem fixed?

[icinga-migration]

Updated by mfriedrich on 2010-09-14 16:22:28 +00:00

can we decide wether to use this issue or #702 instead?

continue in #702 please.
