In addition to C99=1 on the make command line, also allow
C89=1 or C11=1 or C23=1.
NOTE: Those won't all lead to a successful build of NetHack,
and the use of C23=1 (-std=c2x) will only be valid on recent
compiler versions (clang-15, for one, accepts it).
CSTD can be manually set near the top of src/Makefile, util/Makefile
or by including c99=1 or C99=1 on the build make command line if
using the linux.370 or macOS.370 hints files.
1. remove all window interface bits from compiler.370, and have
the preceding include files set some variables to control
the behavior of compiler.370 when it comes to c++.
2. some more common Makefile lines into sys/unix/hints/include/multiw-3.370.
3. make it so you can pass cppregex=1 on the Make command line to build with
sys/share/cppregex.cpp instead of posixregex.c
4. fix sys/share/cppregex.cpp so that it will build with clang compiler
(required an additional header include). I don't know if it would have
worked with g++ without that change. The include can be placed into an #ifdef
block if there's an issue with the change on other compilers.
5. Anything that needs to compile using c++ (Qt, sys/share/cppregex.cpp) can
just ensure that CPLUSPLUS_NEEDED Makefile variable is set above the lines
in compiler.370 to ensure that things get set up for c++. It no longer
checks specifically for Qt. That is what sys/unix/hints/include/multiw-2.370
does now.
Add a 3rd multi-window include file that comes after compiler.370.
Relocate a small section of Makefile lines common to both macOS.370
and linux.370 to multiw-3.370.
Also relocate a section near the tail of compiler.370 that really
has nothing to do with compilers or compiler flags, but was
related to Qt which is one of the supported multi-window interfaces.
Now, the only usage of GCC_WARN is for the guard of PRINTF_F in wincurs.h.
This guard can be removed safely, as PRINTF_F is already used unconditionally in extern.h.
Report stated a -Wformat-nonliteral at line 612,
and a -Wformat-security at line 614
I was only seeing the latter, so I added the former to the
flags in sys/unix/hints/include/compiler.370. Some compiler
versions have that warning on by default internally and others
don't. If the format string isn't a string literal, there's no
inteference with printf argument checking because that only
operates on string literals.
Rename the recently added timestamp file used to throw away old qt
'moc' files from moc.qt5 or moc.qt6 to Qt5.h-t or Qt6.h-t and use
that to also throw away old qt_*.o when switching from Qt 5 to Qt 6
or vice versa. Temporarily the old names remain in Makefile.src's
'clean' target and in src/.gitignore but those will be removed soon.
Update 'make depend' to add the timestamp file to qt_*.o dependencies.
Have it generate rules to build qt_*.moc from ../win/Qt/qt_*.h instead
of using a template rule in hints/include/compiler.370. So building
the Qt interface doesn't require use of that hints file anymore and
someone reading Makefile.src won't have to know about it, but using
those hints will make their life easier.
Simplify the Qt timestamp handling portion of compiler.370. Only one
extra rule gets added when creating src/Makefile.
src/Makefile generated from sys/unix/Makefile.src that's been rebuilt
with 'make depend' got broken by uncommenting '#include "amiconf.h"'
in global.h. That file isn't in include/ but every object file now
depended on it and make didn't know what to do about that. Have
depend.awk treat it as a special case so that no object files depend
on it. That means that actually modifying it won't trigger a rebuild;
anyone fiddling with that will have to always do 'make clean' or
'touch config.h-t' after changing it. The alternative is to move it
from outdated/include/ back to include/.
In depend.awk, recent gawk complained that "\." wasn't a defined
escape sequence in regular expressions so it would be treated as ".".
That's exactly what is intended but change it to "[.]" to avoid the
warning. Similarly for one instance each of "\#" and '\"'. I also
tried changing "\/" to "[/]" even though that is a defined sequence
and doesn't trigger any warning. gawk accepted it but the awk that
comes with OSX choked on it so I changed it back to "\/".
This is an attempt to address the issue of switching from Qt 5 to
Qt 6 or vice versa on Unix without running 'make spotless'. Various
*.h files (but not all of them) in win/Qt/ are run through a program
called 'moc' to create new files *.moc that are included by *.cpp.
The problem is that the constructed files use the same names for Qt
5 or 6 but their contents apparently aren't compatible. This adds
rules (specific to GNU make) that use a pair of timestamp files to
track which version of moc made src/*.moc and to destroy them when
switching Qt versions in order to force their re-creation.
As it stands, a hints file which includes hints/include/compiler.370
is now required in order to build the Qt interface with the Unix
Makefiles. There's no change for platforms that don't use those and
I've no idea whether something comparable could be done for macOS
Xcode IDE.
The first time make is run with WANT_WIN_QT=1 after this is in place,
all the .moc files will be rebuilt and the subset of .cpp files which
include them will be recompiled. After that, the .moc files will be
rebuilt as needed--and only as needed--just like any other constructed
files.
The reason that the QT6.2 build on Linux was getting a warning
on qt_main.cpp, but the QT6.2 build on macOS was not, was
because of a difference in compiler flags between clang++ and g++.
clang++ was using the
-Wno-deprecated-declarations
and g++ wasn't, so add it.
djgpp cross-compiler was griping about several.
This also removes these lines from sys/unix/hints/include/compiler.370.
CFLAGS+=-Wno-format-nonliteral
CCXXFLAGS+=-Wno-format-nonliteral
-Wformat-nonliteral should not be incompatible with the printf
argument-checking capabilities on literal format strings and there
shouldn't be any new warnings created.
