@ -87,6 +87,14 @@ flags specific to Spot:
--disable-assert
--enable-optimizations
--enable-glibgxx-debug
Enable the debugging version libstdc++
https://gcc.gnu.org/onlinedocs/libstdc++/manual/debug_mode_semantics.html
Note that the debugging version og libstdc++ is incompatible with
the regular version. So if Spot is compiled with this option, all
client code should be compiled with -D_GLIBCXX_DEBUG as well. This
options should normally only be useful to run Spot's test-suite.
Here are the meaning of the fine-tuning options, in case
--enable/disable-devel is not enough.
