Maybe you should write something about that (with some cool screenshots). It is hard for us to even imagine how all this would work since we don't speak/read/write Japanese. Thx, Sven

ah, emacs. end of conversation, from the friendly editor. And likely the end of Mozart Oz, only they just can't believe it. Emacs, version 25 on the way to 125. Oz. Version 1.4 and on the way to nowhere, but at least it got there via emacs [ enough said.] ( I remember the senseless attacks on Visual Prolog as Turbo Prolog, on bytecode ( before Java ), DASD in favour of RAM above 640k ... ) If ever a tool set back the development of IDE's before ( gag ) IBM WorkBench/eclipse, it was surely emacs. But then again, someone will link eclipse to the VA Smalltalk team at *IBM*... ( eclipse has almost shuttered the Curl IDE at www.curl.com and www.curlap.com - to my amazement. Only IDE to rival Smalltalk. Pooof ! And with pluggable editors and the code in the package.) To really see the state of editors as components, just try writing tests and docs in Japanese for a week for the programming paradigm of your choice. Yes, time to configure an editor for Japanese is not included,as that would be unfair. ( painful reminder : even Kobo, the e-reader, is lame compared to Amazon Kindle, as a Japanese reader. And the Sony e-reader is gone. And that is just mere Japanese text display without annotation, let alone editing for development. But Apple fans far out-number emacs advocates, don't they? ;-) Pharo 3 for coding in Japanese is now the best IDE of which I am aware. And it is a great pleasure to see that. My thanks to everyone who helped bring Unicode to Pharo and Pharo to Unicode fonts. And there is still no IDE for swi-prolog. Because Logtalk + SWI wouldn't benefir from an IDE, would it.

yes, it changed the glibc. you can try using this version of the vm, it should work: http://files.pharo.org/vm/pharo/linux/pharovm-u804.tar.gz Esteban On 22 Apr 2014, at 01:15, Sergi Reyner <sergi.reyner(a)gmail.com> wrote: > 2014-04-21 23:12 GMT+01:00 GABRIEL DEFAGOT <gaby_defa91(a)hotmail.com>: > /pharo3.0/bin/pharo: /lib32/libc.so.6: version `GLIBC_2.15' not found (required by /pharo3.0/bin/pharo) > > What's missing? > > A newer version of glibc, probably.

Re: [Pharo-users] Error when trying to initiate Pharo in Ubuntu 64 bits

by Stephan Eggermont

Hi Gabriel, Version 11.10 of Ubuntu is no longer supported. That ended nearly a year ago. That means that there is no heartbleed openssl update, you might need to compile a safe version from source. And that also means that there is no recent precompiled pharo for it. If you need to use a machine for a longer time, you might want to either use a LTS version, or upgrade regularly. Stephan

Error when trying to initiate Pharo in Ubuntu 64 bits

by GABRIEL DEFAGOT

Hi, I downloaded pharo 3.0 for linux. Since I'm using Ubuntu 11.10 64bits, I've installed the ia32-libs as the readme file says, but when I run ./pharo the following error is shown: /pharo3.0/bin/pharo: /lib32/libc.so.6: version `GLIBC_2.15' not found (required by /pharo3.0/bin/pharo) What's missing? Thanks in advance.
