Configuration script for the gint library.
Usage: $0 [options...]
You should build out-of-tree by creating a build directory and configuring from
there.
Target selection:
--target=fx9860g|fxcg50
fx9860g covers all fx-9860G II-like monochromes models that support add-ins
or can be flashed with an OS that does. This includes SH3 and SH4 machines.
Default toolchain is 'sh-elf'.
fxcg50 covers just the fx-CG 50; there is some unofficial compatibility with
fx-CG 10/20. All of these are SH4-only.
Default toolchain is 'sh-elf'.
Build options:
--toolchain=TRIPLET Build with a different toolchain
--prefix=PREFIX Install prefix (PREFIX/lib and PREFIX/include are used)
--cflags=FLAGS Additional compiler flags at end of command
Library options (disabled by default):
--boot-log Display a boot debug log at startup if a key is pressed
Used to investigate unstabilities.
--no-syscalls Cut off all syscalls (this will break things)
Only use this option if you have a good idea of which.
--static-gray Allocate gray VRAMs in static RAM instead of the heap
May help when --no-syscalls is on.
Size limits:
--atexit-max=NUM Number of exit handlers in atexit()'s array [16]
Deprecated options (to be removed):
-events-queue-size=<n>
Size of event queue (this mechanism is likely to
disappear in future versions) [64]
