It is not possible to create an executable from direct.i. My compilation fails:
(.text+0x20): undefined reference to `main'
/tmp/cc0VOLHm.o: In function `___H_direct_2d_fft_2d_recursive_2d_4':
_num.c:(.text+0xf1): undefined reference to `___gstate'
_num.c:(.text+0x18e): undefined reference to `___gstate'
_num.c:(.text+0x1c7): undefined reference to `___gstate'
_num.c:(.text+0x27b): undefined reference to `___gstate'
_num.c:(.text+0x2e0): undefined reference to `___gstate'
/tmp/cc0VOLHm.o:_num.c:(.text+0x6f0): more undefined references to `___gstate'
follow
Could you attach the source that can be used to create the executable? Or
perhaps a detailed instructions how to create one from sources you already
posted.
