yes, i only tried to compile this in clang/termux environment.
can you look around (in Makefile may be) if XOPEN_SOURCE defined somewhere?
if yes - try to remove it?

The makefile's just a gcc command, there's no XOPEN anywhere in any file. I cobbled the time.h and endian.h, but it's still a bag of worms. I'm afraid I'm no C programmer. |

try to add few more places with inclydes (gcc -I..)?

there is also libbsd https://libbsd.freedesktop.org/wiki/ |

Well... that does seem to help a little. The unused def helps. Let's see.... put a "stdint.h" here, a sys/time.h there.... linking error! Nuts! getprogname is in bsd/stdlib.h, not sure how to get it work. |

add also 'pkg-config --libs libbsd-overlay'?

Granted, Linux lacking UDF 2.5 write support, I've accomplished rather a Pyrrhic victory with no ability to put anything on said filesystem.... |

and sadly makefs can't put anything in 2.01+ images too...
I used this line for booting netbsd livecd and then mounting device from
inside VM (i used VNC because it was faster on termux, you can use usual
sdl/gtk3 interface..)
qemu-system-i386 -device sb16 -nic user,model=ne2k_pci \
-accel tcg,tb-size=64 -vnc :1 -boot d -vga cirrus \
-cpu pentium2 -m 320 -hda udfimg.img -cdrom netbsd-92-boot.iso
but netbsd's drive notation a bit different from Linux, you better to
consult netbsd's man online
https://man.netbsd.org/NetBSD-5.0/mount_udf.8
in our case it will be wd0* device (not sure wich one exactly)

Am I doing this wrong? Do I need clang? I get tons of u_int vs uint errors, time.h is not sys/time.h - I've got to be doing something terrible wrong. Tips appreciated, thanks.
