Params::Validate

[Joanna Ciomborowska]

Hi All,

I've just started my adventure with Circos.

I have Windows XP, cygwin, strawberry perl and I have a problem with
installing Params::Validate module.
I've tried with:

> perl -MCPAN -e shell
% install Params::Validate

and the results look like this:

what should I do?

From the error message, it looks like the installation step cannot
find the C compiler required to compile the Params::Validate module.

I don't have any experience with Strawberry perl, unfortunately. I
suggest you follow up on a forum dedicated to Strawberry perl.

From the CPAN documentation, it looks like Strawberry perl does
include a C compiler for installing modules.

http://search.cpan.org/~csjewell/Perl-Dist-Strawberry-2.11/lib/Perl/Dist/Strawberry.pm

It's possible that CPAN expects that the compiler location is in your
PATH, but the PATH has not been appropriately updated during
Strawberry installation. See this article

http://win32.perl.org/wiki/index.php?title=Strawberry_Perl#cpan_doesn.27t_set_compiler_path_in_portable_version

Good luck,

Martin

Ok, thanks for help.
I reinstalled strawberry and with another version of this
Params::Validate module - it works :)
but...
another problem occured.
After command
bin/circos -conf tutorials/2/2/circos.conf

programm is running and at the end it shows:
created image at /cygdrive/c/circos-0.52/circos-0.52/output/circos-
tutorial.png

but I can't see this file in this folder...
At the begining I had default seetings with /tmp but .png wasn't also
visible.

what it means?

thanks in advance,
regards
Joanna

Check that the directory exists before writing an image to it. Try
setting

dir = .

in the .conf file. This is the current directory.
