Christophe then goes on to show a helpful example, which example ends
with the line
: mata mlib index
.mlib libraries to be searched are now
lmatabase;lmataado;lmataopt;lcopula;lghquad;lhce;lib_beh_slp;lib_econ;
lib_struct;llib_benchmarksurv;llib_id;llib_matabench;llib_nid;
llib_psw;lnicolib;lnwspgr;lorenz;lpersonal;lplack;lpscorelib;lsimul_hce;
ltauchen;ltaxben;lvfunckw;lfhh;lhalton;lkdens;lsq
Christophe expected to see "laddition" listed after "lsq", but it is
not there. I've taken the liberty of cleaning up the output; the only
point I want to make is that Chrstophe has lots of Mata libraries.
The current versions of Stata 11 and Stata 12 allow up to 255
characters for the list of libraries. Adding ";laddition" pushes
length of the string beyond 255, and thus it was not added.
That the limit is 255 can only be termed a bug. We will fix this in
both Stata 11 and Stata 12.
In the meantime, I suggest Christophe work around the problem by
shortening the names of some libraries. I warn Cristophe that I would
not be surprised if there is no file named lsq.mlib. "lsq" appears at
the end of the list. The string Christophe showed has exactly 254
characters, meaning 255 once the terminating binary zero is added, and
thus I suspect the name "lsq" has been truncated.
Christophe can rename *.mlib libraries without rebuilding them, but I
also caution him that renaming *.mlib libraries obtained from SSC
will confuse -ssc update-, -ssc install-, and -ssc uninstall-.
-ssc- will think any renamed library is personal rather than part of a
downloaded package, and it will think that the downloaded library has
been accidentally erased. -ssc update- and -ssc install- used to
update a package will replace the original library. -ssc uninstall-
will not erase the renamed library.
If Christophe must rename a SSC *.mlib file, just do so, and then be
aware that if he uses -ssc- to update to re-install an existing
package, he will after to erase the renamed libary and then the new
library to the shorter name.
