Hi
Ubuntu's toolchain is configured to set -Wl,--as-needed by default as
to automatically strip superfluous ELF dependencies. This change might
be adopted to Debian in the future.
yforth 0.1beta-22 fails to build with current Ubuntu toolchain setup; a
simple "make" in the source tree fails with:
[...]
gcc -lm -o yforth block.o blocke.o core.o coree.o double.o doublee.o exceptio.o
facility.o file.o filee.o float.o floate.o locals.o localse.o memall.o search.o
searche.o string.o tools.o toolse.o udio.o vm.o ycore.o yfinit.o yforth.o
yfvinit.o
float.o: In function `_floor':
float.c:(.text+0x44d): undefined reference to `floorf'
float.o: In function `_f_round':
float.c:(.text+0x538): undefined reference to `floor'
[...]
Prefixing -Wl,--no-as-needed to the gcc flags allows it to pass.
The fix is to change Makefile as follows; instead of:
$(CC) -o yforth $(OBJECTS) $(MATHLIB)
use:
$(CC) $(MATHLIB) -o yforth $(OBJECTS) $(MATHLIB)
Attaching a debdiff to this effect.
Thanks,
