Re: Problems installing DateTime module ...

Does cpanm not automatically install Cbuilder?

The log says CBuilder is installed

 

Possible compiler flag/switch issues?

You never show any output from any compiler

You show a whole bunch of test failures, showing missing prerequisites

 

Complaints of “no compiler” – where do I set the “c compiler?”

Since you compiled your own perl, you can just ignore this message, its probably a bug in whatever emitted it

Here is one way to check

$ perl -V:cc
cc='gcc';

$ which gcc
C:/MinGW/bin/gcc.EXE

But you shouldn't need to do this, esp if you compile your own perl

 

“Can't locate Params/Validate.pm in @INC” message

Maybe you want to install Params::Validate?

 

Build resorting to “/nas/rhome/dotykg/.cpanm” when I have a “cpanm” version underneath “/rstor/dotykg/PERLBREW/bin”

Configuration directory, configuration files, cache ... does not live under .../bin, and the executable is named cpanm not .cpanm , .cpanm is the config/cache directory

Dear Anonymous Monk:

Thank you for your advice. On the compiler issue, here is what I got doing your tests:

matrix01 51# perl -V:cc
cc='cc';
matrix01 52# which gcc
/usr/bin/gcc

I tried installing Params::Validate but I wind up with the same snag:

Do you possibly have any other ideas? Many thanks, Kevin Doty

Dear Anonymous Monk:

After my last e-mail I was looking in ithis directory: /nas/rstor1/dotykg/PERLBREW/build/perl-5.8.9 in the “config.sh” file and it shows the following assignments:

cc='cc'
cccdlflags='-fPIC'
ccdlflags='-Wl,-E'
ccflags='-fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_
+SOURCE -D_FILE_OFFSET_BITS=64'
ccflags_uselargefiles='-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64'
ccname='gcc'

Should the variable “cc” be defined “gcc”? If so can I define it properly and do a reconfigure/reinstall? Many thanks, Kevin Doty

Dear Anonymous Monk:

My system uses the environment modules system:

http://modules.sourceforge.net/

In my .cshrc file I was loading several modules. When I removed all module loads and re-installed Perl 5.8.9 I was successful installing the DateTime module. I had several modules loaded (including Portland compiler, MPICH2, HDF, NETCDF, and IDL). - hard to say which one was the culprit.

Many thanks, Kevin Doty
