src/response.cpp:169:57: error: no member named 'st_mtim' in 'stat'
  result.headers["Last-Modified"] = make_date(stat_info.st_mtim.tv_sec);

I get this error when using Apple LLVM version 10.0.0 (clang-1000.10.44.4) for Target: x86_64-apple-darwin18.2.0. I tried to look into it, but I am having an issue figuring out what this exactly does. I attached stat.h from the Apple SDK library.

I can switch to st_mtime instead, I didn't realized st_mtim was linux-specific.

jyn514 commented 5 years ago

Should be fixed in https://github.com/jyn514/crappy-server/commit/0a53c39da3e9ffa2af24e81d3d1dc09a5c6a7fcf, feel free to reopen if it doesn't work.

jyn514 commented 5 years ago

By the way, the error is this:

The library call stat is a wrapper around the system call of the same name. It takes in an output parameter of type struct stat *. On Linux and FreeBSD that struct has a field called st_mtim which returns the last time the file was modified and is more accurate than the older st_mtime. However it's less portable (as you can see from the error) and I don't need the accuracy, so I changed it to the older field.

Run man stat for more info.
