[PURRS-devel] Apparent non-termination of NTL's `make check' (version 5.3.2)

[Roberto Bagnara]

Dear Sir,

I have downloaded NTL 5.3.2 and I have configured it with the command

$ ./configure NTL_GMP_LIP=on NTL_STD_CXX=on GMP_PREFIX=/usr/local

Doing `make' proceeds fine, even though the MakeDesc command seems
to print the wrong version number:

$ make
make setup1
make[1]: Entering directory `/usr/local/distrib/ntl-5.3.2/src'
gcc -I../include -I.  -O2 -c MakeDescAux.c
gcc -I../include -I.  -O2  -o MakeDesc MakeDesc.c MakeDescAux.o -lm
./MakeDesc
This is NTL version 5.3.1

GOOD NEWS: compatible machine.
summary of machine characteristics:
bits per long = 32
bits per int = 32
bits per size_t = 32
arith right shift = yes
double precision = 53
NBITS (maximum) = 30
single mul ok = yes
register double precision = 64
double rounding detected = yes
-- auto x86 fix


mv mach_desc.h ../include/NTL/mach_desc.h
[...]

When I do `make check', the process arrives to the following point

[...]
running LLLTest
LLL_FP...0
LLL_QP...0.02
LLL_XD...0.03
LLL_RR...0.18
G_LLL_FP...0.01
G_LLL_QP...0.07
G_LLL_XD...0.07
G_LLL_RR...0.52
LLL...0.01
LLLTest OK

making subset
make[1]: Entering directory `/usr/local/distrib/ntl-5.3.2/src'
g++ -I../include -I.  -O2  -o subset subset.c ntl.a  -L/usr/local/lib -lgmp -lm
make[1]: Leaving directory `/usr/local/distrib/ntl-5.3.2/src'
subset 40 40 20 10 999999 f
n: b: size: prune: seed: alg [fqQxr]: +

and then sits there for ages.  On my machine, an Athlon 2800 running
Red Hat Linux 9, the `subset' process is running since almost 5 hours now.
I am using GCC 3.4.1 and GMP 4.3.1.
Have you any idea what the problem may be?
Thanks a lot,

     Roberto
