--as-needed needs to come before the object files and libs to be
effective but libtool moves it to the end. This happens with both
1.5.26 and cvs head.
The fact that libtool reorders _any_ of the command-line is a bug. I
think Ralf has a fix for this but I don't think it'll happen until 2.1
or 2.2.
Still there in libtool 2.2
As a workaround until we get this fixed, if an automake based project
try 'make CXXLD='g++ -Wl,--as-needed' CCLD='gcc -Wl,--as-needed'.
I'll look into this.
Peter
that does not help:
[EMAIL PROTECTED] ~/cpp/libtooltest $ grep CXXLD *
Makefile:CXXLD = $(CXX)
Makefile: --mode=link $(CXXLD) $(AM_CXXFLAGS) $(CXXFLAGS)
$(AM_LDFLAGS) \
Makefile.in:CXXLD = $(CXX)
Makefile.in: --mode=link $(CXXLD) $(AM_CXXFLAGS) $(CXXFLAGS)
$(AM_LDFLAGS) \
But with CXX set to CXX='g++ -Wl,--as-needed' it does work. I don't know
if that will break anything but we shall see.
I also wonder why libtool brings all these dependency libraries with
