Comment (by gouezel):
I already tried a different linking order, it does not make any
difference.
Here is the difference between (working) sage.6.8.beta2 and (failing)
sage.6.9.beta2 regarding symbols:
in 6.8.beta2:
{{{
nm /home/Sebastien/sage13/sage/local/lib
build/temp.cygwin-1.7.35-x86_64-2.7/build/cythonized/sage/modular/arithgroup/farey_symbol.o
| grep _to_SL2Z
000000000001f190 T convert_to_SL2Z
nm build/temp.cygwin-1.7.35-x86_64-2.7/sage/modular/arithgroup/farey.o |
grep _to_SL2Z
U convert_to_SL2Z
}}}
in 6.9.beta2:
{{{
nm
build/temp.cygwin-2.2.0-x86_64-2.7/home/Sebastien/sage15/sage/src/build/cythonized/sage/modular/arithgroup/farey_symbol.o
| grep _to_SL2Z
000000000001cfa0 T convert_to_SL2Z
nm build/temp.cygwin-2.2.0-x86_64-2.7/sage/modular/arithgroup/farey.o |
grep _to_SL2Z
U __imp_convert_to_SL2Z
}}}
looks like the symbol in farey.o got prefixed by `__imp_`for some reason.
So, the symbols in the two files do not match... Is this `__imp_` some
kind of cython magic? Is it there on other platforms?
