Re: [Xotcl] How to build XOTcl 1.6.8 so that it works with both Tcl 8.5 and 8.6?

Dear Yusuke,
building XOTcl binaries with Tcl 8.5, that work with Tcl 8.6 is actually
not quite simple,
since when XOTcl is compiled under Tcl 8.5 uses the Tcl function
TclObjInterpProcCore(),
which was unfortunately removed from Tcl in 8.6. The commit entry, which
deleted the
stub entry in Tcl 8.6 says:
"Used to be needed for TclOO-extension; unneeded now that TclOO is
in the core
and NRE-enabled"
Therefore, when one loads the binary from Tcl 8.5 into Tcl 8.6, this
symbol cannot be
resolved. See as well the discussion in [1].
However, to address this problem, i've added a new configure
option "--enable-forward-compat86", which allows to build binaries of XOTcl
with 8.5, that do not use TclObjInterpProcCore(), and can therefore be
loaded into Tcl 8.6 as well. You can get this version currently just
from git
git clone git://alice.wu.ac.at/nsf
cd nsf
git branch xotcl1 origin/xotcl1
git checkout xotcl1
Use "--enable-forward-compat86" only in cases, where you need the forward
compatibility. One will get better performance under Tcl 8.5 or Tcl 8.6
by compiling
exclusively for these versions.
best regards
