Re: Please help -- errors while compiling Scratch tarball (T#562835)

  Thread Previous • Date Previous • • Thread Next 
Hello Jean,
Just today we made a beta .rpm package of Scratch available on our website. This package was contributed by a community member, and needs testing. Please try it out and let us know how things go. 

http://info.scratch.mit.edu/Scratch_on_Linux
The package spec file is available on the Assembla site linked from the same page, so if you'd like to contribute changes, let me know and I'll add you to the Assembla team. Anyone should be able to report bugs / tickets via the Assembla page.
Hopefully, the package will work for you, and compiler errors won't matter. At a glance, it looks like the errors are caused by failed dependencies on libpango and libcairo. The .rpm spec file available on the Assembla site (or the Debian control file) should declare / describe all the various dependencies necessary to compile the plugins. 

Scratch On!

Hello Amos,

We'd really appreciate help getting Scratch installed on SuSe linux.
If we get it working I would likely introduce ~300 UPenn undergrads
to Scratch during the upcoming year, as I would include it in the
lab work for my intro programming course.

Hi Amos Blanton,

I have been directed to contact you with regard to a problem that I am
having trying compile the Scratch tarball for our systems.

We are running SuSE Linux 11.2 and, as there was no RPM package
available for RedHat/SuSE systems, I downloaded and unpacked the tarball
that was supplied on the Scratch website.

I am at a loss as to how to continue, as it won't compile.  Here is the
output of errors (warning, it's long):
