Suppose one has an ISA executable file (e.g., an application that

X86-64. If under OTHER the executable file is built with only
static libraries -- no dynamic .so calls -- will it execute under
SL 7? That is, when system (kernel) calls are made by the
executable, will the use of a different kernel and glibc generally
cause the executable to fail? I am restricting the discussion to
the X86-64 ISA, not an arbitrary ISA for which OTHER may be available.

It depends on how statically it is compiled. I have seen things which
were listed as static but only for everything but glibc. In that case
you need to install the x86_32 glibc to get it working. That said..
when things are super static you can end up with hunt the file I
need.. it is static but is looking for a file which is in a 32 bit
directory.
So some of the time it will work, some of the time it won't. Without
knowing more about what ldd and say strings says about the
executable.. not sure which category your executable will fall in.

My intention is this. There exist applications on various other
distributions (Fedora, Ubuntu, SuSE, etc.) that do not exist and will
not build under SL 7. The intent would be to setup a development
machine of the other distro, build the application from source as static
as possible (with bloat by this mechanism), include whatever directories
or files that need to be present, and then run the thing under SL 7 .
In a worst case, rather that using a physical machine, install the other
distro in a virtual machine under VirtualBox (that runs very well under
SL 7) -- with enough disk space assigned to the Virtual Box machine to
allow for such a build. Some applications (such as a full window
manager) I would not consider, but there are others of more limited
generality that I would.
