GMPlib tuneup building bug

[Cyclopropinon]

Hello,

I encountered a bug while trying to build the tuneup tool.

Version I downloaded: https://ftp.fau.de/gnu/gmp/gmp-6.3.0.tar.lz

I got the same problem on both systems I tried on.

System 1 (Ubuntu 24.04.1 LTS):

./configure --enable-fat --enable-cxx

gcc version 13.2.0 (Ubuntu 13.2.0-23ubuntu4)

uname -a: Linux (device name) 6.8.0-45-generic #45-Ubuntu SMP 
PREEMPT_DYNAMIC Fri Aug 30 12:02:04 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

.config.guess: k8-pc-linux-gnu

.configfsf.guess: x86_64-pc-linux-gnu


System 2 (Ubuntu 22.04.5 LTS):

./configure --enable-fat --enable-cxx

gcc version 11.4.0 (Ubuntu 11.4.0-1ubuntu1~22.04)

uname -a: Linux (device name) 6.8.0-47-generic #47~22.04.1-Ubuntu SMP 
PREEMPT_DYNAMIC Wed Oct  2 16:16:55 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

.config.guess: haswell-pc-linux-gnu

.configfsf.guess: x86_64-pc-linux-gnu


Problem:

$make tuneup
gcc -DHAVE_CONFIG_H -I. -I..  -I.. -I../tests   -O2 -pedantic 
-fomit-frame-pointer -m64 -c -o tuneup.o tuneup.c
gcc -DHAVE_CONFIG_H -I. -I..  -I.. -I../tests   -O2 -pedantic 
-fomit-frame-pointer -m64 -c -o hgcd2.o hgcd2.c
make: *** Keine Regel vorhanden, um das Ziel „sqr_basecase.c“,
   benötigt von „sqr_basecase.o“, zu erstellen.  Schluss.

(translated: make: *** No rule to make target 'sqr_basecase.c', neede by 
'sqr_basecase.o'.  Stop


Steps to reproduce:

download & extract gmp-6.3.0

following the guide (https://gmplib.org/manual/Installing-GMP):

$./configure --enable-fat --enable-cxx

$make

$make check

(all checks pass)

now following https://gmplib.org/manual/Performance-optimization:

$cd tune/

$make tuneup

gcc -DHAVE_CONFIG_H -I. -I..  -I.. -I../tests   -O2 -pedantic 
-fomit-frame-pointer -m64 -c -o tuneup.o tuneup.c
gcc -DHAVE_CONFIG_H -I. -I..  -I.. -I../tests   -O2 -pedantic 
-fomit-frame-pointer -m64 -c -o hgcd2.o hgcd2.c
make: *** Keine Regel vorhanden, um das Ziel „sqr_basecase.c“,
   benötigt von „sqr_basecase.o“, zu erstellen.  Schluss.

running it again results in:

make: *** Keine Regel vorhanden, um das Ziel „sqr_basecase.c“,
   benötigt von „sqr_basecase.o“, zu erstellen.  Schluss.

(but this time without the previous lines)


I hope this helps in finding the bug!

Sincerely,
