prelink

According to [1], prelink is no longer needed.

When I configure wine-1.9.6, I get the warning message,
"configure: WARNING: prelink not found and linker does not support 
relocation, base address of core dlls won't be set correctly."

Hi there,

So I'm not one of the devs but my first question would be are your 
build-tools (specifically the linker, "ld" for gnu or "lld" for clang) 
relatively up-to-date? Prelink used to be the default way to set the 
DLLs in a specific memory location (for the occasional program that 
expects that), but prelink brings a lot of baggage with it.

I think Fedora actually stopped packaging prelink altogether a while 
back, and I know Debian no longer builds their wine packages with it. 
Apparently there are other ways to solve any problem that prelink can, 
but you also need some newer linker features.

For a little background, here's a mailing-list discussion...
https://www.winehq.org/pipermail/wine-devel/2015-August/108695.html
... and here's the patch that explains your warning message:

Thanks for the information and links.

A distro I compile in:

ld --version
GNU ld (Linux/GNU Binutils) 2.18.50.0.2.20071001
Copyright 2007 Free Software Foundation, Inc.


Another distro I compile in:

ld --version
GNU ld (Linux/GNU Binutils) 2.20.51.0.2.20091009
Copyright 2009 Free Software Foundation, Inc

It is good to know that when I decide to compile with a newer version of 
my distro, with the included updated 'GNU ld', I will no longer need 
prelink.

This means your binutils version might not yet support the -Wl,-Ttext-segment option.

Ciao, Marcus
