Cygwin uses newlib for its C library. From what I can see, qsort is there but qsort_r isn't. > There was a commit in libgit2 that was supposed to fix this : > > https://github.com/libgit2/libgit2/commit/0d77647adc1f76df66e437e6442d7f7706e2c38e#diff-bb2cd4651768482b99cb1c52d29ceffdR694 > > but I don't know enough about Cygwin internals to determine why it still > fails on Cygwin. The problem with that patch is that it doesn't take Cygwin into account. If you append a check for Cygwin there as well (i.e. defined(__CYGWIN__) ) then that should resolve the compile issue. -- Larry _____________________________________________________________________ A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting annoying in email? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
