ZdcPluginMissing: SSL/TLS plugin initailization failed (VM plugin missing ? OS libraries missing ?)

by Offray Vladimir Luna CÃ¡rdenas

Hi, I'm trying to deploy a small web app in Teapot, following the Enterprise Pharo documentation and so, using Pharo 4 in the server. Installation went fine, but when I try to actually use the app and I get this error: ZdcPluginMissing: SSL/TLS plugin initailization failed (VM plugin missing ? OS libraries missing ?) Looking at [1] I see that this is because Pharo VM is expecting to found libssl at some place. My server is a virtual Debian 6 64 bits, as provided by Digital Ocean. When I locate the missing library and make a symbolic link using: ln -s /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 /usr/lib/libssl.so.1.0.0 I still get this behavior: ldd libSqueakSSL.so linux-gate.so.1 (0xf7747000) libssl.so.1.0.0 => not found libc.so.6 => /lib32/libc.so.6 (0xf758b000) /lib/ld-linux.so.2 (0xf774a000) So, still is not finding the libssl.so. [1] https://stackoverflow.com/questions/12293670/zodiac-mail-sending-in-pharo-s… I don't know if this is related with running a 32 VM inside a Debian 64 bits distro, but running the chapter 2 example of the Enterprise Pharo, I have not any problem like this one, on the same virtual server while deploying the web app. How can I solve this? Thanks, Offray

Re: [Pharo-users] PharoJS

Norbert: Great answer. Spoken like a wise man. I want a web app to fill paper forms - like income tax forms say. The forms are scanned or input into the app. The developer provides the logic connecting the input and output fields of the forms. The users then use the app to fill their own forms, print them or send them electronically. Can Smalltalk provide a superior solution? How?

Craig: Great news for Pharo. I presume it will be after you are done with Squeak running on SqueakJS. Do you have a roadmap. How will WebAssembly help or not with project?

Re: [Pharo-users] Are we able to run pharo images in a read only environment?

by Tim Mackinnon

Thanks Sven - I was going to search for that as I recall it being talked about. I will give it a go and report back on results with Lambda. Iâm not sure how sensitive it is to image sizes and trying to open that file - so it will be interesting.

The error about saving the changes file comes from the fact that at startup, Pharo tries to open Pharo.changes in read and write mode, which is impossible if you are in a read-only environment. I am working on deploying Pharo in read-only, and it's one of the main problems that shows up during my tests. -- View this message in context: http://forum.world.st/Are-we-able-to-run-pharo-images-in-a-read-only-enviro… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
