Hello,


Does anybody know how to deal with this gem problem ?

Thanks a lot in advance for your help.

After trying to run gem update the message is:
gem update

Do you have a working C compiler available ? The error message suggest
that you don't

Hi Fred,


thanks a lot for your answer !

No, I don't think so. I am running this in a (minimal) Windows Vista
installation on Virtual PC (to easily correct for mistakes, as I just
started to learn ruby and rails).

I have not installed anything that would include a C-compiler.

Is there a special one to install to run with ruby ? And where would I
put it ? In the ruby folder ?

If a special one is not required, which one would you recommend ?


thanks a lot


Peter

I thought that hpricot had a pre-built binary gem for windoze?

Hi Peter,

Try this command:

gem install hpricot --platform mswin32 --source http://code.whytheluckystiff.net

Gerson,

That worked for me on Windows Vista Home Premium.

Thanks for the tip!

Hi Philip,

could you tell me, please, what exactely you did; as for me - I am still
getting the same error (after doing successfully: gem install hpricot
--platform mswin32 --source http://code.whytheluckystiff.net)

I also tried the gem update --with-make-prog option, but something
is wrong with that option ( or the way I am putting it), its not
accepted.

Even though I downloaded and installed hpricot (as mentioned above) the
gem update fails as mentioned in my initial posting.

So maybe a detailed description of what you did might help ? --I hope !!


Hi Gerson,

thanks a lot for the tip, even though for me it was not the breakthrough
yet.

Best

Peter

Hi,



Visual C 6.0 won#t install in Vista (at least I can't) get it istalled.
Would anybody know how to do that (as VC 6.0 apparently can't deal with
the Vista environment)



Best

Peter

Dear Peter,

this might have to do with Vista wanting you to have administrator rights....
You can set them in "system preferences" or look here:

Dear Axel


thanks a lot for your suggestion. The problem seems to be more
fundamental: at least when I try to install VC 6.0 within my VirtualPC
Vista I am getting an errror message (very early on during installation)
which must be somehow related to an address conflict. It seems that VC
6.0 is using 16 Bit addresses and Vista can't handle these ?!

Do you have any idea what to do ?



Best regards,
