Forum OpenACS Development: xotcl-core doesn't load on HEAD

Posted by Dave Bauer on 01/25/08 09:29 PM

I installed from HEAD today. xotcl-core does not seem to work.

I have xotcl 1.5.4 installed.

% package require XOTcl
1.5.4

Hmm, this code (checking the xotcl version) is unmodified since a long time (16 months) and is part the stable version in the oacs-5-3 branch. This variable is set by xotcl by versions since 2001.

I have the suspicion that you have multiple versions of xotcl installed on your system, or that your xotcl installation is broken. What do you see if you "fgrep XOTcl .../log/error.log"? Did you make an "make install-aol"?

Btw, the head version requires XOTcl 1.5.* or newer (1.5.6 recommended). The code in the serializer tests for backward compatibility for versions before 1.4, and can be mostly dropped (which i will do now).

Looks like it found 1.5.4 but it then can't get past the version check.

Those Tcl comments in the log are from the error stack trace when it tries to load xotcl-core.

I had not done make install-aol for some reason when I installed XoTcl. After doing that it works great!
