[esp-r] Re: res crashes when netflow results should be shown

Tue Jul 22 14:26:57 BST 2008

Hi Holger,

Are you compiling ESP-r from source (that is, using a sandbox checked
out from svn)? If so, check which version of gcc you're using:

  $ gcc -v

If the result is gcc 3.4.X, then everything's probably ok. The Install
script should correctly locate the gcc/g77/g++ compilers, and link in
the correct libc and libstdc++ libraries. But if your default compiler
is set to gcc 4.+, you need to specify the '--gcc4' command line
argument during installation. Run the following command from the src
directory for more information:

  $ ./Install --help

If you fail to specify '--gcc4' on a system with gcc4 compilers, the
install script will likely find the version 4.X gcc and g++ compilers,
but will probably use the version 3.4 g77 fortran compiler. It will
probably link these against the version 4.X libc and libstdc++
libraries. 

These library and compiler mismatches will produce unpredictable
results, and might well generate the stack-smash error you encountered.
Even if you're using the '--gcc4' option, I can't be certain which
library your binaries will be built against if other gcc libraries are
present on your system.

Truth is that many linux distibutions do a poor job managing multiple
versions of the gcc compiler. Gentoo provides a useful script called
gcc-config, which allows users to cleanly switch between multiple
versions of gcc, and updates the environment variables to point to the
correct libraries. Does anybody know of similar tools for Ubuntu and
other distributions?

Hello Jon,

ESP-r 11.5 is running on Ubuntu 8.04.
I chosed X11.

But I'm not sure about the compiler.
Is it the gcc?
On my system are gcc-3.4 and gcc-4.2.
If I had been asked,
I'd chosen the recommended...
Can I check this afterwards?

Thanks and best regards,
Holger
