[QUOTE=alexvong1995;425343]Hi people, could you try appending --enable-verbose-compiler and --disable-silent-rule when running configure and paste the output? (I don't want to give away my phone number to register...)[/QUOTE]

Sure. But you can always use a "burner phone" in such cases. I know guys who have a half dozen or so for just such instances... :wink:

But here are the results of what you asked for:

[CODE]configure: WARNING: unrecognized options: --disable-silent-rule[/CODE]Oh I forget a "s". :rolleyes:
[CODE]../src/platform.h:1072:4: error: #error Multithreading currently only supported for Linux/GCC builds![/CODE]Judging from this line, maybe we should try to build without multithread. Maybe we can try ./configure --enable-verbose-compiler --disable-threads and see what happens.
By the way, --help should show all options of configure. (only the Custom Options part is useful)

[QUOTE=alexvong1995;425358]Maybe we can try ./configure --enable-verbose-compiler --disable-threads and see what happens.[/QUOTE]

This is the last help I'm going to provide on this matter.

Create your own account to debug further on the IBM 390 mainframe....

We are still awaiting Ernst to speak.

Usually he is rather loud. His silence is notable.

Edit: Casts got your tongue?

There are two distinct issues here - [1] the basic code-build and [2] the automated Linux/x86-oriented build scripts - which should be tackled in turn. I'll let Alex focus on [2] since he developed the scripts.

As to [1], the OP mentions having 'tried' the pre-build-script-wrapped 14.1 release - what precisely was tried? The manual build instructions on the README page? Note that due to the non-x86 CPUs here we are stuck with the non-SIMD basic scalar-double C build. But it's still always useful to work through build and code issues on non-primary-target platforms, to make/keep the code as portable as reasonably possible.

So to the OP (or anyone else with access to this platform - I will look into a guest account over the weekend), try the most-basic manual build first: straight C, unthreaded - i.e. no USE_ flags of any kind in the compile command.

As for the threading-related preprocessor #error, if this platform supports pthreads it should be a simple matter of tweaking the platform.h header to look in the right place for the pthreads-related header files. Looking at the #error line Alex quoted in my platform.h file, it's clear the
[i]
#include <pthread.h>
[/i]
is not finding the pthread.h file. Is there one in the /include tree on this platform?

The part about the Mlucas_12.11.2014.tgz release not supporting that kind of auto-build, possibly.

You missed this:

I was referring to the 'and' part of the OP's second sentence:
[i]Tried compile MLucas (mlucas-14.1.tar.gz and Mlucas_12.11.2014.tgz)[/i]

How about this (in get_fft_radices.c, lines 1443-1446):
[CODE] case 7 :
numrad = 6; rvec[0] = 16; rvec[1] = 8; rvec[2] = 8; rvec[3] = 8; rvec[4] = 8; rvec[5] = 16; break;
#ifndef USE_ONLY_LARGE_LEAD_RADICES
case 7 :
numrad = 5; rvec[0] = 8; rvec[1] = 16; rvec[2] = 16; rvec[3] = 32; rvec[4] = 16; break;

[linux1@rhel7-3 build]$ gcc -Os ../src/get_fft_radices.c

[/CODE]Their gcc compiler is a bit stricter than on x86_64 (I've built it before -- no problems were reported, only warnings).

A bit later (in TRICKY section)
[CODE]../src/util.c: In function ‘print_host_info’:
../src/util.c:1071:106: error: ‘OS_BITS’ undeclared (first use in this function)[/CODE]so add -DOS_BITS=64 to the compiler line.

After polishing these two little blemishes, runs like a clock.
