I’ve been spending the holidays to upgrade some of my own servers. One of them is the Sguil server I use. Until now it ran Debian Squeeze. On Debian Squeeze you could use tcl8.3, which has threading disabled. For Sguil tcl threading needs to be disabled:
ERROR: This version of tcl was compile with threading enabled. Sguil is NOT compatible with threading.
This is a compile time option in TCL, and the Debian Wheezy packages have it enabled by default. Here are the steps to create your own tcl deb with threading disabled:
# apt-get install dpkg-dev # apt-get install devscripts
Get the tcl8.5 source package and build deps:
# apt-get source tcl8.5 # apt-get build-dep tcl8.5 # cd tcl8.5-8.5.11/
Next, edit the debian/rules file to disable threading. Remove the line:
--enable-threads \
Then, build the package:
# debuild -us -uc
And finally install the package:
# cd .. # dpkg -i ../tcl8.5_8.5.11-2_amd64.deb
I followed this guide here at Debian Administration. It has some more detail on rebuilding debs.
if you are using 8.6, you need to explicitly disable it by replacing –enable-threads by –disable-threads.
you also have to remove the line Tcl_GetMemoryInfo from debian/libtcl8.6.symbols : this one is only declared when building with threads
