Please post your complete issue here, thanks.

hello，I have complete this issue.

from gtsam.

I believe the issue here is that the system function is not available on iOS. From the MacOSX.sdk stdlib.h

__swift_unavailable("Use posix_spawn APIs or NSTask instead. (On iOS, process spawning is unavailable.)")
__API_AVAILABLE(macos(10.0)) __IOS_PROHIBITED
__WATCHOS_PROHIBITED __TVOS_PROHIBITED
int	 system(const char *) __DARWIN_ALIAS_C(system);

A fix for you could be to conditionally compile the system call in DecisionTree-inl.h. That is the only place it is used. We would welcome a PR and I can help land it. It should be really simple to fix.

Thanks. I will push a PR a few days later.

@11janson since we don't officially support iOS, your best bet moving forward is to fork GTSAM and either remove that function or conditionally compile it for your purposes. Closing this issue.
