[Opengrads-devel] x86_64 portability

[Arlindo da S. <da...@al...>]

Jennifer,

  I am trying to get to the bottom of the portability (or lack thereof) of
grads binaries for x86_64. Some observations:

1) In my experience, binaries linked with g++ are more vulnerable than those
linked with plain gcc.

2) The gcc version used hardly matters provided it is gcc v3 or newer.

3) The libc/libstc++ version seems to to be the key issue.

4) In some cases, providing your own libstdc++ does the trick (if the one
required is older than what is on the system), but when you bring a new
libc/libstc++ to an older installation it lead to segmentation faults.

Do you agree with 1) -4)? Could you send me the version of the libc/gcc you
use for your x86_64 builds? Just enter:

% rpm -qa | grep glibc
% gcc --version

  Thank you,

         Arlindo
