In an ideal world we don't want them, right?
I've just been building the 13x tree using Dec's make and find that
the src tree is almost Ok. The changes I have to make are to the
build rules for our 'unusual' sources.
Eg, this in src/frontends/xforms/forms/Makefile.am:
%.C: %.fd
$(SHELL) $(SCRIPT) $<
The '%.C: %.fd' thing, meaning the .C file depends on the .fd file,
whilst intuitive, is a gnu make-ism. The standard make way is:
.SUFFIXES: .fd .C
.fd.C:
$(SHELL) $(SCRIPT) $<
Which is written in Makefile.am as:
SUFFIX = .C .fd
.fd.C:
$(SHELL) $(SCRIPT) $<
Patch attached. Ok to apply to 13x, Jean-Marc?
The same sort of thing is present in the qt frontend, although the
problem is more complex:
src/frontends/qt2/ui/Makefile.am contains:
%.h: %.ui
$(UIC) $(UICFLAGS) $< -o $@
%.C: %.h %.ui
$(UIC) $(UICFLAGS) -impl $^ -o $@
Fixing the first of these is trivial '%.h: %.ui' -> '.ui.h:'.
However, the second is more complex.
1. The .C file depends on the .ui file '%.C: %.ui' -> '.ui.C:'
2. The .C file also depends on the .h file -> '.ui.C: $*.h' ???
3. '$^' in the build rule. The line above expands to:
/usr/local/kde/qt/bin/uic -tr qt_ -impl QMathDialogBase.h
../../../../../src/frontends/qt2/ui/QMathDialogBase.ui -o
QMathDialogBase.C
so, somehow '$^' is expanded to 'QMathDialogBase.h
../../../../../src/frontends/qt2/ui/QMathDialogBase.ui'
Ie, it is probably equivalent to '$*.h $<' but I haven't got this to
work yet.
Any input from the gurus?
