Problem with '-flto=N' on MinGW

Problem with '-flto=N' on MinGW

[niXman]

HI,

I've built MInGW using the sources GCC version 4.7.1.
When using LTO '-flto=N' when N greater  1 - I get the following error:
> "make": [C:\Users\niXman\AppData\Local\Temp\ccl7QYlh.ltrans0.ltrans.o] Error 1 (ignored)

If I use '-flto' или '-flto=1' then the error is absent.
Tell me please, where is this error printed from? Because of what?
This error is found also in gcc-4.6.3 and gcc-4.7.0.

I'd like to have an working LTO whith more than one thread.

Thanks!

That should not be the only error message.  What are the other ones?

When you use -flto=N, GCC simply turns that into a -j N option for
make.  Perhaps your copy of make does not suport -j?

The option should only support GNU make with jobserver feature

Did you build make using --enable-job-server?

I think it's not supported by default on MinGW in the past, but I don't 
know it now.

I remembered  Ozkan Sezer wrote some patches for it, but I have no idea 
whether GNU Make has accepted them.

Forward it to Ozkan Sezer, I think he knows it.

Does GNU Make CVS support it now? Or need some patches?

At the time I built that package, the make configury didn't used to
enable job server for windows targets even if you did specify the
--enable-job-server argument to configure, so I manually changed
the generated config.h after configuring (look in the package to see
how it was built.)  Don't know whether it is enabled now in the make
CVS version.

I just replaced the make.exe/mingw32-make.exe to those in the archive,
reference to which you have given.
But the problem remained.
Ideas?

It's possible that Ozkan isn't subscribed to the list.  I added him to
the CC list.

I unfortunately have nothing else to offer you :(

It has been quite some time since I compiled something on windows,
therefore I can't help you at the moment.  You may try compiling make
from CVS-latest and see whether it makes a difference.

I tried. Result is the same.

Can anyone tell me where make is running from?
