��Hi Stephane,

I shall read that Metacello chapter. I had considered this case closed until you replied again. I took another peek and I think I found the root cause. And for the sake of those who stumble on this email thread, I should clarify this.

This is probably related to my old email thread about running Pharo 5.0 on linux with old glibc, which resulted in Pharo5.0-linux-oldLibC download to work properly.

http://lists.pharo.org/pipermail/pharo-users_lists.pharo.org/2016-October/028431.html

Following your solution, after installing PetitParser from Catalog Browser in Windows version, I noticed the ConfigurationOfPetitParser version is TudorGirba.80, the version I had problem in linux. I then wondered why it didn't work on my linux with old glibc versions. Here's what I found

Download and version (SystemVersion current imageVersionString):

centos �� Pharo-5.0-50761-

linux �� Pharo-5.0-50772-

linux-oldLibC �� *Pharo-6.0-60257-*

Pharo5.0-linux-oldLibC has image for Pharo 6.0. This is the one I use where PetitParser installation failed.

Using Catalog Browser, or Gofer instruction from smalltalkhub, for #load and #loadDevelopment versions, PetitParser installation works fine for images that come from linux and centos ��versions, but not from linux-oldLibC.

So, I believe that is the problem. I'm not sure what's the right solution, but I think I can stay in this image and use TudorGirba.77 version or I can try using image from linux version.

Thanks again. If you hadn't replied about Metacello, I'd have never taken another look and found this.

You should read the beginning of the chapter on metacello.
Metacello is a map
Monticello element of the map

You load elements by asking the map.��

Hi Stephane,

Indeed, PetitParser installation from Catalog Browser works just fine! Thank you very much.

I used Monticello Browser before, but not Catalog Browser. I didn't know this is the preferred method to install package. I don't think DeepIntoPharo mentions about Catalog Browser, but maybe my version is outdated.

Thanks again, Stephane.

Sorry I meant the catalogBrowser.
Using the catalogBrowser on a given version of Pharo you should access the configuration for this version (if people updated it correctly).��
Our plan is to make sure that such configurations are validated.��

Hi andreas

Normally you should be able to load a package using the ConfigurationBrowser and the configuration (now I do not know the one of PetitParser)
should take care of the pharo version for you.��

Following DeepIntoPharo, I tried to install PetitParser into my Pharo 5.0 image (I noticed PetitParser installation problem email in March). It failed with the message WinPlatform class was undefined. I went to Moose's PetitParser site in smalltalkhub and followed the instruction there, and this also failed.

Out of frustration, I downloaded Moose 6.0 and thought I'd start from Moose image instead. But then I noticed Moose's PetitParser package has ConfigurationOfPetitParser from version TudorGirba.77 and the instruction I followed was trying to install it using version TudorGirba.80. Back to my Pharo 5 image, I unload/remove ConfigurationOfPetitParser and load version TudorGirba.77. And this works!

But this way to solve PetitParser installation problem seems wrong. I figure if this could very well happen with other packages too. What is the right way to find package version that works with my image/pharo version? Or is this an issue with PetitParser package itself and should I ask/report this to Moose team?
