Jürgen,
ok, just pulled revision 1142. turned off treating warnings as errors via
./configure CXX_WERROR=no
gor a bunch of sem_init deprecated warnings
also got the following:
-----
Workspace.cc:595:13: warning: use of logical '&&' with constant operand
[-Wconstant-logical-operand]
if (mode && SIM_debug) out << endl;
^ ~~~~~~~~~
Workspace.cc:595:13: note: use '&' for a bitwise operation
if (mode && SIM_debug) out << endl;
^~
&
Workspace.cc:595:13: note: remove constant to silence this warning
if (mode && SIM_debug) out << endl;
~^~~~~~~~~~~~
-----
i replaced '&&' with '&' at the flagged location (OK?)
i'll do make install, try to run, and see what happens
best regards
Jeff H. Derby

Subject: Re: [Bug-apl] errors building gnu-apl 1.7
Hi Jeff,
the warning regarding -Wconstant-logical-operand is bogus. I have
nevertheless
updated the sources; the line now reads:
ostream * log = (LOG_startup != 0 || LOG_Svar_DB_signals != 0) ? & cerr :
0;
You can either fix that line manually, or update to the latest SVN version
1138 where the
line is corrected.
The sirst two warnings (-Wnull-dereference) are a little obscure since the
indicated
line numbers in ScalarFunction.cc do not show anything close to the
printout of the error.
This could have two reasons:
A. you compile a rather old version of GNU APL (for examle the one stored
on the GNU mirrors).
In that case I would recommend to fetch the GNU APL code from our SVN
repository at savannah
(see https://savannah.gnu.org/svn/?group=apl with an empty modulename).
B. your compiler expands some macros somewhere and displays the expaneded
text while
loosing track of the source code lines. In that case I would disable this
particular warning
(reconfigure the sources with something like:
CXXFLAGS = -Wnonull-dereference ./configure
). I believe these 2 warning are also not significant.
Best Regards,
Jürgen

should i just turn off treating warnings as errors?
