Some Notes on Building for Linux from Latest Stable (0.9.63)

Postby Feanor76 » Mon Jun 05, 2006 17:33

Hi folks,

I'm sorry these notes aren't in better shape, but I'm really short on time these days. Regardless, to get from downloading the latest stable distribution (0.9.63) to a working build on Linux required a couple steps for me. Here are my crash course notes:

Regards,
Mark

************************************
* still have to build _orngCRS.so
************************************
**** grab source from CVS: (not the orngExtn
**** from Alex's website which is older)

export CVSROOT=:pserver:cvs@estelle.fri.uni-lj.si:/CVS
cvs login
cvs co orngCRS
cvs logout

cd to orngCRS/src


**** edit the Makefile ... depending on swig output: I used
**** clustind_wrap.c clustind_wrap.o

**** also, make sure python paths are correct

**** don't bother with setup.py ... just use the makefile
**** .... it will create "bin" in the orngCRS directory that
**** is the _orngCRS file we're after

**** This compiles _orngCRS
**** Copy _orngCRS to orange/



*****************************
get the orange/setup.py file (either from cvs install_scripts or a
recent daily snapshot)
*****************************
**** grab install_scripts from CVS
export CVSROOT=:pserver:cvs@estelle.fri.uni-lj.si:/CVS
cvs login
cvs co install_scripts
cvs logout
**** and fish out the toplevel setup.py file

*****************************
get a few missing build files
from the daily snapshot
*****************************
*** grab the cvs snapshot (of orange) either directly
*** from CVS or the dailysnapshot and copy over
*** orange/source/orangene
*** orange/source/orangeom
*** orange/source/pyxtract
*** to the version you want to build

**** dedos everything (i.e. make sure that all newlines
**** are unix friendly .... look for the dedos file for
**** hints on this)

**** add newlines to all the *.h *.c *.cpp etc files
**** this just prevents an annoying gcc warning (ugh)
for i in *.cpp; do echo -e "\n" >> $i; done

build with orange/source/Makefile to test things out

should have all the *.so files in orange/ at this point

(add a version name to orange/setup.py)
build from orange/ with python setup.py and either
do the system install or to a custom directory (I did custom directory and then copied it to /usr/lib/python2.3/site-packages)


copy all these files to python2.x/site-packages/
tinker with orange.pth (maybe)

make /usr/lib/liborange.so a link or a copy of orange.so

in some of the orng* modules ... replace whrandom with random (orngCI, orngTest)

Thanks, Mark. You've left out two important things that would really interest me, though. Which gcc and which Python?

We're just fixing the problems with gcc 4.0. I fixed the sources, but wasn't able to compile due to some missing libraries, so I left it for Tomaz to finish the checking (he's our only Linux man, for now). But if you already successfully compiled the newest version from cvs with gcc 4, that's great.

Regarding Python version, you probably use 2.4, since you mention whrandom. I stilll use 2.3, but tried to link Orange against 2.4 and it worked fine, except for the whrandom warning. I already replaced it with random (on Friday, so your snapshot must be older than that :).

I added dedos and newlines to our to-do list.

Thanks,
Janez

Versions

Janez,

I used Python 2.4 (as you guessed). Unfortunately, I only used gcc 3.4.6 ... because of issues with gcc 4.1 (with orange and other projects - I'm waiting a bit until that gets sorted out).

As far as the gui stuff goes, I'm using:

sip 4.2.1
PyQwt 4.1
PyQt 3.14.1-r1
Qt 3.3.6-r1

which was good enough to build without complaints and I fired up OrangeCanvas briefly ... enough to see that it was usable ... but I didn't test it at all.

Regards,
Mark

success with snaphot 06-27

Postby marko » Wed Jun 28, 2006 17:59

I have successfully installed orange (from snapshot 06-27) on Ubuntu dapper with help from tMark's instructions. I only needed to add "_orngCRS.so" to list of libraries in setup.py That was needed to get nomogram widget to work.

Why isn't orngCRS included in snapshots and why is it not included in source/ folder like everything else?

I used gcc 4.0.3. It worked flawlessly. I also didn't need to dedos anything (in contrast with 0.9.63).

Hi,

thanks for your notes. For what it's worth, I'm planning to make a Debian package, so it should be then easy to adapt it to Ubuntu. I'll get back to you in some time, currently I'm quite busy with exams and stuff like that. Don't hesitate to ping me if I don't show up soon. ;-)

Hi,

I'd just want to tell you (in case you haven't noticed) that the C++ code now requires numpy instead of Numeric, and we are also doing the same with widgets. We plan to leave Numeric behind soon. (Numeric and numarray will be supported, but not used.)
