fourspriter error with -O 2 option - jevilon - 02-07-2013
When I try to build my game, using fourspriter 2.1, if you compile normal works, but if I put optimization level 2 or level 3 gives me the error:
main.bas: 5526: error: Undefined label '__LABEL__fsp21DataPool'
Na_th_an I asked and he said that you mentioned it to you.
greetings

It is logical.
Fourspriter has some routines just to contain assembler code or data. These routines never have been called from basic but yes from assembler code.
Compiler optimization process removes mentioned routines, but then them can't be called from assembler.
Perhaps Boriel can detect these kind of situation in compiling time to solve it

It could be the best solution.

Could you help me on that?.
