Cross-Compile for ARM - NTP 4.1.1 OK, NTP 4.2.0a Errors

I'm cross-compiling NTP on a Red Hat 7.3 Linux box, targeted at an Arcom ARM-based embedded board, with the Acrom Embedded Linux (AEL) 3.7 (kernel 2.4.26) host environment installed.

With NTP 4.1.1 (original included in Arcom's AEL package, no known diffs from core NTP dist), all it takes is './configure --host=arm-linux' and 'make' to get a clean compile.

With ntp-stable-4.2.0a-20040617 and ntp-dev-4.2.0a-20040914, the './configure --host=arm-linux' and 'make' routine gets me a nearly immediate screen full of errors ...

   ... in directory libntp
   ... systime.c and/or a_md5encrypt.c
   ... /usr/include/bitsmathinline.h In function 'atan2' ... error: unknown register name st(1) in 'asm'
   ... (ditto the line just above for nearly every match function known to man ;)

Maybe I'm just not familiar enough with the options I need to feed to configure to get it to set up all the include paths correctly for a cross-compile environment?

-

Also, on a related topic, any suggestions for the best set of configure options / etc. to built and configure NTP for operation in a stand-alone environment?

We have a number of embedded processor boards that will be operating in the same box with a Trimble ThunderBolt GPS-disciplined clock board, and these systems will not be connected to any other servers or clients.  We want NTP to keep the Linux clock disciplined to the GPS time from the ThunderBolt, so we can use Linux/ACE timers for software scheduling, and so that we can fall back to the OS clock as a last resort if we lose the GPS.

So the compiler you are invoking is arm-linux-gcc?

It looks like your toolchain is messed up.

I have the same problem to cross-compile for PPC the NTP 4.2.0.
Because I have no idea about how ./configure works, I do the next to
cross-compile


1�. Configure
=============

execute ./configure with your options


2�. Modify ./config.status
=====================================

This file is created by ./configure and is executed as the last step by
../configute

a) find @CPPFLAGS@ in the file and delete "-I/usr/include" from the line
where @CPPFLAGS@ is defined
b) find @LDFLAGS@ in the file and delete "-L/usr/lib" from the line where
@LDFLAGS@ is defined

NOTE: If you use openssl, there is other two line as this for openssl

3�. Execute ./config.status
===================================

../config.status


4�. Modify Makefile files
===================================

a) find the string "AR = ar" in the Makefile files recursively and change
"ar" with you utility for cross-compile
(in my case "AR = ppc_8xx-ar")

b) open the file ./ntpdc/Makefile and do the next
 b1) find "cmp" (case sensitive, word only) y put "echo " before -> echo cmp
......
 b2) find "./ntpdc-layout" (case sensitive) y put "echo " before -> echo
../ntpdc-layout ....

../ntpdc-layout is an utility created when you execute "make" that check
something (i don't know what), but
it is not necessary. As you are cross-compiling, executing ./ntpdc-layout in
the host don't work.


5�. Build and install
=======================

make
make install

I hope this help you.

As far as I can tell, the ARM toolchain is OK. I re-built 4.1.1 from a clean
distribution using:

   ./configure --host=arm-linux
   make

and both completed without errors. I checked the ntpd with 'file' and it said
it was an ARM executable. Moved ntpd and ntpq to the target board, configured
with the NMEA ref clock driver and ntpd and ntpq ran fine. Unfortunately, the
NMEA ref clock driver I've been using as my 'reference' for testing (until I
have the new ThunderBolt driver finished) appears to be broken on 4.1.1 - it
appears to be getting valid $GPRMC sentences but throws a bad time event after
each one. This is one of the reasons I want to be running 4.2.0a+ instead, as
there have been a number of fixes to the NMEA ref clock driver since 4.1.1.

Thanks for the follow-up ... and I owe the group a follow-up of my own.

I _did_ finally manage to get NTP stable 4.2.0a to build for the ARM platform,
with the help of the detailed hints from FJPSE, reading some Net docs on the
auto* tools and Canadian cross-compiling with them, and some NTP spelunking on
my own.  In the end I managed to get the process to work repeatedly without
requiring any mid-stream hand-editing of any files.

As soon as I get the ARM build fully tested and get out from underneath the
heavy load I'm carrying now, I'll post the details of what I did for all.

Hi everyone, Background: ----------- I'm very new to CORBA, ACE & TAO. I'm trying to integrate with a 3rd party system which exposes a CORBA object model to clients. This system is composed of JACOrb 1.4.1 servers registering with an ORBacus 4.1.2 NameService. We've got existing software that uses ACE 5.4.2, and the 3rd party documentation mentions that people have used TAO (no version specified) previously to integrate with their system, so I'm trying out TAO 1.4.2 as a natural solution to the problem.

LISP is the name of the programming language invented in 1959 by John McCarthy and of the first program implementing it written amongst other by Steve Russel, one of his students. LISP 1.5 is a segueing version of that same program dating about 1962 that had some distribution. Then various lisp languages were developed at various places by various teams.

The server, which normally exhibits a load average below 1 most of the time, spiked to loads that approached 100 if left alone. The interesting part of this is that this load average seems to be almost artificial - it appears to be caused by httpd processes stuck in a "closing connection" state (TIME_WAIT, in netstat).

Are these 2 versions compatible with each other in both directions? If I develop with 1.4.2, can it run against 1.4.1 JRE? Thanks. johnhurt@gmail.com wrote: > Are these 2 versions compatible with each other in both directions? If > I develop with 1.4.2, can it run against 1.4.1 JRE? Thanks. I believe that 1.4.x are all compatible. In the principle of versions 1.4.2 correct ONLY BUGS from 1.4.1 (previous version). So as it's only corrections on bugs and not ADDITION of functions there are no risk. But If you develop under 1.5 there could be several problem if you use the new functions added just in 1.5 version and want compatibility with 1.4 versions. It's like upgrade system on Linux. When a distribution is out they just upgrade to correct bugs but they "never" (in stable version) propose a new version who add new functions because it can cause several problems to cohabitate with the different packages on the system. ...

Problems after Update XFree 4.1.x to 4.2.1.1
Hallo, since i set my debian release from stable to testing, i had some problems with XFree4.2.1.1 that i can't get solved. After installation XFree4.2.1.1 didn't start, because the GLX module couldn't be loaded, so i removed that module. Now XFree86 runs, but with many warnings.

Serialization between Java 1.1.4 and Java 1.4.1
Hello, It seems to me to be in some kinda trouble. I wanted to implement communication between Java applet and Server through sockets and Serialization. So, I serialize Object, send it to server which deserialize it with no problems. In other direction problems came out since Object serialized under Java 1.4.1 seems to be not deserializable under Java 1.1.4. (MS VM). If applet si run under J2, there are no problems, but I cannot push people to download some 15MB of new JRE just to accomplish my requirements, especially if applet needs not implementation of features of new JRE... ...

Film scanner for 2 1/4 inch by 2 1/4 inch
Hi folks, I posted this over on the rec.photo.digital newsgroup earlier today and within a few hours there were three helpful and informative reply postings. Thanks much. One of them suggested that I try this newsgroup. So here it is - - - I am new to film scanning and I am seeking advice on the purchase of a film scanner. I have hundreds of APS, 35mm, and 2 1/4 by 2 1/4 inch negatives that I would like to scan. I realize that the 2 1/4 by 2 1/4 inch requirement may be a problem. Any suggestions? Thanks for your help.
