Am I the only one having issues trying to get this working? The webserver starts just fine, but once I add the index.html with zip as in the example, it stops working.

IIRC, from vague memories of things flying past, Big Sur won't let a modified binary run once it's been checked by Gatekeeper. Which means the first run gets checked and notarised but when you add the `index.html`, the on-disk binary has changed and Gatekeeper won't allow it to run - I guess it's to prevent malicious code modifications, etc.

I've been programming since before you were born... and this is the most impressive hacking feat I've ever seen. A single executable, that doubles as a valid ZIP file, that you can put a complete website into, also doubles as a valid executable on Windows, Mac, Linux. The build infrastructure is a complete reworking of C to make it far more portable than even K&R thought possible. I probably wouldn't have believed it…
Multi OS/arch executables exists for decades. They were called fat-binaries[0]. Old trick is new again. [0]: https://en.wikipedia.org/wiki/Fat_binary https://en.wikipedia.org/wiki/Universal_binary
I just spent 30 minutes reading about this. I'm so shocked that I'm logging in to comment after 5 years of lurking. Justine has built a c library that allows you compile a binary once and have it run it on any os or baremetal. The SAME binary. Quite frankly, that sentence doesn't even make sense to me.

Agreed, this is the best programming-related thing I've seen on the internet in a long time. It reminds me of when I was a teenager, excited to become a computer programmer. Then I grew up and joined the real world workforce and it was all far less exciting than I imagined. The coolest thing about this Actually Portable Executable is that once there's a compiler and linker built with it, I can play around with writin…
Maybe I have a blind spot or something or I've just been in Unix-land for too long.
As amazing as this is unfortunately it doesn't work for me and I am on Linux. I get bash: ./redbean.com: No such file or directory after chmod-ing. Maybe I am dumb but yeah.

I think it's really cool project; but could you explain why it's important that a binary works everywhere for you? I don't really get the enthusiasm for this sort of thing. Maybe I have a blind spot or something or I've just been in Unix-land for too long.
But on Windows, trying to get open source software written in C to compile has been a pain for decades. There have been some attempts to make it work (notably Cygwin, and now MSYS2), but it can still be challenging, especially with programs that were never designed to be compiled for non-UNIX (or non-Linux!) targets.
Having a C library that is designed from the ground up to target multiple operating systems, and an executable format that means the first compile is the only compile, that takes away a lot of toil that programmers normally have when trying to build their own abstractions around each platform's C library. I guess from UNIX land you could see the benefit as removing the need for autoconf or platform ifdefs.

Wow, that cosmopolitan C library is absolutely awesome. The ABI specialization is extremely interesting. Never seen anything like that before. I thought compilers did that. I don't understand why they couldn't properly optimize memcpy. I wonder how it handles system calls. Let me check the source... https://github.com/jart/cosmopolitan/blob/master/tool/build/... https://github.com/jart/cosmopolitan/blob/master/tool/b…
Yeah, it would have taken less bits to use GNU/POS instead, because it ain't Linux anymore.
Poettering Operating System.
I tried to run it on an old 32bit pc with Linux. But it complained about not knowing the format of the executable. But it would be awesome if I could get it to work somehow.
