When I created the test schematic I had the same problem. However this
time I also added the original 74HCT245-1.sym from the gEDA symbol
library and assigned the desired TSSOP.. footprint from Luciani and it
worked fine! So the problem is in my modified version of the
74HCT245-1.sym. I modified the original version of the symbol so that I
had the power and GND pins on the symbol rather than defaulting to the
nets defined in the symbol. I also moved some pins around and deleted
the default footprint of DIP. Thinking that every symbol must have a
default footprint I assigned the default to the desired TSSOP... and it
still failed.:) I did a difference between the original and my version
and I don't see anything obvious. I ran gsymfix.pl which modified it
but didn't fix the problem.
So at least we have it narrowed down to the symbol. So what could be
wrong with my symbol that would cause an M4 error?
Note:
I attached my modified version of the 74HCT245-1.sym.
I placed your symbol in a schematic, changed the footprint attribute and
gsch2pcb ran correctly. I loaded the resultant PCB file and placed the part.
NB: I do not have any m4 libraries and only use newlib parts that are stored in
my production directory.
