# Note: this linking command will not work correctly when jpgalleg or loadpng
# are linked statically (Note how we patched allegro to make sure these are
# always compiled as dynamic libraries). The problem probably is, that
# Build/Compile adds these linking options to early in the command line, and
# static libraries won't resolve symbols of objects added later on.
#
# You won't even see a compiler error; the resulting _alpy.so would be going
# to segfault due to an unresolved (0-pointer) symbol.
