We've all seen cases where a quick patch is rejected in favor of a
hypothetical patch, and years down the road, the program still has the
problem. The people who blocked the quick patch, naturally, never
bothered trying to write the patch they wanted.
That's a mistranslation. It means that there are other criteria
beyond some people having trouble. Such as, we really want multilibs
to be built.
This is an interesting conflict of requirements. I see the point of both
sides, being a developer on one side and being a user on the other.
I really appreciate the fact that I got a clear message telling me to
install mpc. I would have hated needing to google for a cryptic error
message.
How about a middle-ground, not aiming at cross compilation?
If --enable-multilib or --disable-multilib are passed then things
are performed as today, more or less. If these flags are not
explicitly given then gcc has to do something different:
If the system compiler is GCC then 'configure' tries if the system
GCC can build i686/x86-64/x32/etc. If the system gcc creates
workable executables then all is fine and 'configure' proceeds
to a multilib build.
Otherwise an error will be emitted saying something like:
"
I can't figure out if your system has [???] development libraries.
If you have [???] then rerun configure with
--enable-multilib
If you don't have [???] then you should rerun configure with
--disable-multilib
You should note that if you pass --enable-multilib despite having
no [???] development libraries, then you would likely get the
following error at the last stages of bulid:
gnu/stubs-[???].h: No such file
"
This should be relatively simple to implement, and will catch most
cases. I guess that a native English speaker can phrase something
more readable and welcoming.
