Re: [IPCop-devel] try to build IPCOP on sparc64 - stopped on gcc

[Doug A. <dou...@gm...>]

64-bit userland in Gentoo and other linux sun4u distros definitely
doesn't work.  You absolutely need to specifiy 32-bit, unless things
have changed very recently.

Have you checked emerge to see what glibc version you have installed,
and what version is expected by IPCop?  On my sparcs and hppas running
gentoo, I frequently had problems with "old" compilers and libraries.

Sorry I can't be of more help, but maybe that will point you in the
right direction.
