GCC:: __gxx_personality_v0 problem

GCC:: __gxx_personality_v0 problem

[Lindsay Braine]

Dear Mailing List,

I am trying to use gcc to compile a simple .cxx file, but am getting the 
following error 'symbol __gxx_personality_v0: referenced symbol not 
found' when I try and use the created shared object. Can anyone provide 
some insight into why this might be occuring (looking at web search 
engines has revealed that it might be a configuration problem with 
previously installed versions of gcc clashing - but I have never had 
another version other that the one I am using!)

I am using GCC version 3.1
I am on Sun Solaris 8
Configuration information is :
->gcc -v     
Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.8/3.1/specs
Configured with: ../configure --with-as=/usr/ccs/bin/as 
--with-ld=/usr/ccs/bin/ld --disable-nls
Thread model: posix
gcc version 3.1

and my compilation command file reads :

echo "Compiling C Wrapper Code"
g++ -fPIC -c -I/usr/java1.2/include -I/usr/java1.2/include/solaris 
-I/space/otherlibs/libs service_wrap.cxx 
echo "Linking C Wrapper Code"
ld -G -o libservice_wrap.so service_wrap.o functionslib.o

Any help/pointers/answers would be gratefully recieved.
Best Regards,
Lindsay.

compiling GLIBC-2.2.5

[RMD]

I need to compile glibc-2.2.5 on a 686 machine, for a i486 target.

In the web, I read things like "This package is known to behave badly when
you have changed it´s default optimization flags (including the -march
and -mcpu options), GLIBC is best left alone, so we recommend you unsetting
CFLAGS, CXXFLAGS and other such variables/settings that would change the
default optimization values it comes with. Also, dont pass
the --enable-kernel option to the configure script. It´s known to cause
segmentation faults when other packages like fileutils, make and tar are
linked against it"

This remains true? If so, how can I build a glibc on a pentium-class machine
for another x86 target?

Don't know much about solaris, but I woud have done what you're trying to 
do as:
g++ -fPIC -c -I/usr/java1.2/include -I/usr/java1.2/include/solaris 
-I/space/otherlibs/libs service_wrap.cxx
g++ -fPIC -shared -o libservice_wrap.so service_wrap.o functionslib.o

(note that functionslib.o has to be compiled with -fPIC, I guess)

This may help, or it may not :-(
