[gentoo-user] Bug 919184 - sys-libs/libstdc++-v3-3.3.6-r4

Dear list,

I'm trying to install the Checkpoint client for linux (cshell_install). It
requires sys-libs/libstdc++-v3, 32 bits. I couldn't compile it and found
this bug: https://bugs.gentoo.org/919184

Do you know any way of work around this? Maybe copying the binary file from
another distro or try to use another gcc version?

Thank you,

TIL that we have a twenty-year-old libstdc++ in the tree.

It's running a test program to find the glibc minor version:

  #include <features.h>
  main(argc, argv)
       int argc;          
       char *argv[];
  {
    printf("%d\n", __GLIBC_MINOR__);
    return 0;
  }

But this test program, having been written 20+ years ago, is crap. It's
missing <stdio.h> and a correct signature for "main" at least. Newer
GCCs (like the one that you're using) will refuse to compile it. So the
test fails unexpectedly, and the build stops. You might be able to
trick it by disabling -Wimplicit-int, -Wimplicit-function-declaration,
and whatever other warnings that program raises... but then you have to
actually compile the rest of it with a new GCC. Good luck :)

Maybe we should mask it?
It is supossed to work with gcc <3.4 and the oldest we have is 8.5.0, which is masked already.

Hi.
I don't know if you tried, but passing -fpermissive via /etc/portage/env
is not enough.
You need to write wrapper scripts to get around the gcc14 issue.

It shouldn't be *that* hard.

https://bugs.gentoo.org/923112#c13

And as Sam noted:

"""
I concur with Eli and Enne. We should just strip it all. It's a brittle
package for ancient binaries.
