gcc_personality and strtol

[dmatt0001]

Hi All,

I'm trying to do a test compile of a library (contains one function with a for loop just for fun) and main routine which prints the program name using iostream and then calls the library routine. Sounds simple eh?

Well this is where I am having some problems. If I use the i_static icpc option everything is good. If I just use the static option, things go bad. I have included the output below.

I suspect it is something to do with the default lib and include paths. If I use the -# option, I see that in fact icpc is intentionally linking with

I am using the intel version 9.0 compilers installed on a linux machine in my home directory. There is nothing strange in my environment. I sourced iccvars.sh only.

Thanks for your time, I have included compile output below incase there is an obvious missuse of the tool on my part!

Regards,

Matt

From my experience this has to do with exception handling. If you add -lgcc_s to your link command it links fine. I don't know excactly where the problem comes from though. You can also try compiling without exception support if you dont need it. The option for that is -fno-exceptions.

I hope this helps,
