requirements to compile libtorrent & rtorrent

[James]

I have been abot to use the binaries posted here (rtorrent 0.84.1) on
my DNS-323 with chrooted Debian Lenny. Since ARM version of the
binaries will no longer be posted, is there any "tricks" that one
needs to knwo to compile them under Debian? I tried it couple of times
but the results were not sucessfully.
I also tried to do "apt-get -t experimental..." route but 0.8.4-1 is
the latest.
Thank you in advance,
James

Most of the information I got from http://www.osix.net/modules/article/?id=827.
You need to install the packages listed there to have a valid compile
environment.

build-essential
libsigc++-2.0-dev
pkg-config
comerr-dev
libcurl3-openssl-dev
libidn11-dev
libkadm55
libkrb5-dev
libssl-dev
zlib1g-dev
libncurses5
libncurses5-dev
libtool
automake
svn-arch-mirror
libxmlrpc-c3-dev
libwww-dev
libexpat1-dev

I use 3 scripts for the compile :

1) Get the code from the repository

svn co svn://rakshasa.no/libtorrent/trunk/libtorrent
svn co svn://rakshasa.no/libtorrent/trunk/rtorrent

2) Compile rTorrent

export CXXFLAGS="-O2 -mcpu=xscale -mtune=xscale"
cd libtorrent
./autogen.sh
./configure --disable-debug
/etc/init.d/rtorrent stop
make install
cd ..

3) Compile Libtorrent

export CXXFLAGS="-O2 -mcpu=xscale -mtune=xscale"
cd rtorrent
./autogen.sh
./configure --disable-debug --with-xmlrpc-c
make install
cd ..

The trick is to add the export for the armv5tel line of processors
(export CXXFLAGS="-O2 -mcpu=xscale -mtune=xscale"), otherwise it will
compile but will not run stable.

Works like a charm. Oh, it takes some memory and it will definately
use swap space. I swap on a USB stick to keep the compile time down,
because otherwise the disk movement will impair speed tremendously. If
you need more help, just ask.

Thanks. I have all the packages installed but can not find libwww-
dev.
Doesn't look like it is available for Lenny.

A newbie question. You have make install but no make. Is this just a
copy and paste error or there is no need to "make"?

Hmm, me neither, probably renamed or no longer needed. I cannot find
it on my system and I compile ok.

Nope, seen it for Etch and Sid, not for Lenny (weird)

Make is a program you have on your system (or "apt-get install make"
if you do not have it). The ' Install' tag in the makefile compiles
and moves the result to the install directories, which are /usr/local/
lib and /usr/local/bin. So you can either call the specific steps in
the make process or just 'make install' to do everything with one
command.

[James]

Thanks. Whether I use make then make install or just make install,
compilation did not work.
Anyway, in case someone else is using the instructions, can you
clarify the following?

2) Compile rTorrent


export CXXFLAGS="-O2 -mcpu=xscale -mtune=xscale"
cd libtorrent
./autogen.sh
./configure --disable-debug
/etc/init.d/rtorrent stop
make install
cd ..


3) Compile Libtorrent


export CXXFLAGS="-O2 -mcpu=xscale -mtune=xscale"
cd rtorrent
./autogen.sh
./configure --disable-debug --with-xmlrpc-c
make install
cd ..

Is libtorrent needs to cofigure with --with-xmlrpc-c or rtorrent needs
to?
Thank you again.

When you get the sources with the svn command, 2 directories are
created from the directory where you started them (the svn commands).
The dirs are 'rtorrent' and 'libtorrent'. You need to compile
libtorrent first.I always compile as 'root' in the /root directory.

> export CXXFLAGS="-O2 -mcpu=xscale -mtune=xscale"

This defines an environment variable that tells the compile process it
needs to optimize for the SLUG.

Thank you for your clarification. In the original post, you have step
2 as "2) Compile rTorrent" even though the details are for libtorrent.
Just want to make sure.

For my attempt to build libtorrent, autogen and configure went ok.
However, make generates whole bunch of error messages:

James,

Which version of libtool do you use ? Mine is :

libtool --version
ltmain.sh (GNU libtool) 1.5.26 Debian 1.5.26-4 (1.1220.2.493
2008/02/01 16:58:18)

If you enter "libtool --help" you should see that it supports --tag
as one of the options. just run ' apt-get --install libtool' to make
sure you have the latest version installed.

[James]

I have the same version..

libtool --version
ltmain.sh (GNU libtool) 1.5.26 Debian 1.5.26-4 (1.1220.2.493
2008/02/01 16:58:18)

Just for fun, I did "apt-get install libtool" and got

Reading package lists... Done
Building dependency tree
Reading state information... Done
libtool is already the newest version.


This is a very strange problem. I used to be able to compile rtorrent/
libtorrent several months back (before I used your ARM version of the
binaries). Binaries were generated but they crashed shortly after
startup.

[hhasert]

Weird. Thew crash was probably due to not setting the environment
variable, I did a cross compile and that had the same problem, it
started but crashed soon. My 'make'generates the same command :

/bin/sh ../../../libtool --tag=CXX --mode=compile g++ -
DHAVE_CONFIG_H -I. -I../../.. -I. -I./.. -I./../.. -I../../.. -O2 -
mcpu=xscale -mtune=xscale -DNDEBUG -fvisibility=hidden -I/usr/
include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -MT block.lo -MD -
MP -MF .deps/block.Tpo -c -o block.lo block.cc

and works fine. The only difference is that I have the dir under /
root and do not have libtorrent-0.12.5 but just plain libtorrent as a
directory. I do not have a clue what is going wrong, but being
pranoid, you have installed gcc and g++ compilers ?

I do have both installed:
gcc --version
gcc (Debian 4.3.2-1.1) 4.3.2

g++ --version
g++ (Debian 4.3.2-1.1) 4.3.2

[hhasert]

James,

I do not have a clue (yet) what is wrong. I tried to break stuff to
generate the same error, but I haven't been able to get closer to a
solution. Have you tried to compile as root in the directory /root ? I
see you have a mounted volume where you placed the files, if that is a
non unix filesystem something odd might break. Like I said, I am
clueless, never seen this before.

[James]

I tried to put the latest libtorrent under /root/libtorrent but have
the same results. I have no idea why this is happening. The mounted
volume is one of the two hard dirves I have for my DNS-323. They are
both formated by DNS-323 with ext2 format.
The interesting fact is I have no problem making the latest
transmission client.

[James]

I downloaded and made libtorrent-0.12.4 without error with the same
setup. I only did a "make" but not "make install" because I don't want
to distrub my existing installation.

[hhasert]

Did you put a ticket to libtorrent ? See http://libtorrent.rakshasa.no/ticket/1852
I do not see a resolution though. Do you have the output of autogen
and configure ?

I appended my console output including autogen and configure to ticket
1852.
Thanks.

[hhasert]

Ticket 1852 has a suggested solution :

rm -f scripts/{libtool,lt*}.m4

and then try again with ./autogen ; ./configure ; make

[James]

Thanks, I saw that. libtorrent went OK but gcc has seg fault when I
"make" rtorrent. Need to repeat everything again when I have a chance.
BTW, I saw at a blog that xmlrpc needs to be compiled also. Can I
reuse what I have from rtorrent 0.84?

[hhasert]

James,

I never recompiled xmlrpc and use the default package. Problem is that
it is a 32bit version, so the responses in number format get incorrect
representation in XMLRPC. I solved that in my interface by requesting
rTorrent to translate these to strings, so I cricumvent the issue.
