building guiqwt under ubuntu:fortran issue

[jean-patrick]

I try the following command to build guiqwt:
sudo python setup.py --fcompiler=gfortran install
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help

error: option --fcompiler not recognized

gfortran is installed. What command should I use to build guiqwt?

Regards

The last version that I installed was 2.0.8 (on a ubuntu 10.10)

**As far as I remember** I just used "setup.py install --user" (without -
fcompiler) and it autodetected gfortran...

I hope that helps

I created a symbolic link called gfortran to usr/bin/gfortran-4.5 and
the compilation work.

Hi all
This is for guiqwt-2.1.0/guidata-1.3.0

There are some fortran-f90 compiler concerns for buiding guiqwt only:

1-The status of fortran compilers depends on the numpy.disutils
tuning.

2-On Ubuntu Maverick amd64 , all is compiling out of the box.

3-On RH5 amd64 , I succeded with :

python setup.py build_ext --fcompiler=gnu95 build

There are lot of warnings buildind doc :
...........
running build_doc
Running Sphinx v1.0.7
loading pickled environment... done
building [html]: targets for 0 source files that are out of date
updating environment: 0 added, 1 changed, 0 removed
Module 'guiqwt.image': missing fortran or C extension
.........

I guess there is no need for fortran for docs ...

4- Options for fcompiler are different for build and build_ext.

Hope this helps

Claude

Thanks Claude for the feedback.

I'll include this in the next bugfix release README.

The "Module 'guiqwt.image': missing fortran or C extension" warning
appearing when building doc has been handled in the development
version and guiqwt v2.1.1 (to be released soon) will include the
bugfix.

This may be a closed topic, but I am uncertain how to proceed with this error.  I am attempting to install guiqwt-2.3.1 on my Ubuntu machine and whenever I run "sudo python setup.py install" it works fine, but whenever I want to use it to install another program it says that "Module 'guiqwt.image': missing C extension" and it tells me that module histogram2d cannot be found.  How should I proceed?
