[Win32] Cannot 'make speed' in the 'tune' folder

[sisyphus1 at optusnet.com.au]

Hi,

I built gmp-6.1.0 in an msys shell with:
./configure --disable-shared --enable-static --enable-assembly && make && 
make check

It passed all tests.

Then I cd to the tune directory and run 'make speed':

$ make speed
gcc -std=gnu99 -m32 -O2 -pedantic -fomit-frame-pointer -mtune=corei7 -march=corei7 
speed.c   -o speed
speed.c:43:20: fatal error: config.h: No such file or directory
compilation terminated.
make: *** [speed] Error 1

On Ubuntu (where 'make speed' works fine), the command that gets run 
includes "-I..  -I.. -I../tests", and it's the omission of those flags that 
causes this Windows failure.

However, looking at the Windows tune/Makefile (attached as Makefile.orig) 
and comparing it with the Ubuntu tune/Makefile, I cannot see why those flags 
are being omitted on Windows.

It's not so hard to get past this failure - I chose to set CPPFLAGS (which 
is initially empty) to "-I.. -I../tests", but then I get:

$ make speed
gcc -std=gnu99 -m32 -O2 -pedantic -fomit-frame-pointer -mtune=corei7 -march=corei7 
 -I.. -I../tests   speed.c   -o speed

C:\Users\sisyphus\AppData\Local\Temp\ccHW0ipc.o:speed.c:(.text+0xaba):

.... and many more.

I guess the problem here is that the missing "-c" flag means that we're 
trying to build speed.c into an executable named "speed".
On Ubuntu speed.c gets compiled into an object file named speed.o.
What should I try next ?

Oddly enough, if I run 'make tune' then there's no need to modify the 
original Makefile - though 'make tune' subsequently fails to compile after a 
while.
I'll make this the subject of another bug report after this one has been 
sorted.

In case the 'make tune' output throws some light on the problem with 'make 
speed' here's how 'make tune' terminates:

... many successful compilations ...
/bin/sh ../libtool  --tag=CC   --mode=compile

make[1]: *** [time.lo] Error 1
make[1]: Leaving directory `/c/smoke_mpfr/gmp-6.1.0/tune'
make: *** [tune] Error 2

I haven't run anything in the 'tune' directory before, so I'm unable to say 
whether these are new problems or not.
FAIK, they may not even be gmp bugs.

Cheers,
Rob
