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. This is on Mac 10.15, CentOS 8 and Ubuntu 18.04 LTS. Centos: [centos@test ~]$ ./redbean.com -vv error: Uncaught SIGSEGV on test.novalocal ./redbean.com EINVAL/err=22/errno:2/GetLastError:0 Linux test.novalocal 4.18.0-240.10.1.el8_3.x86_64 #1 SMP Mon Ja…

Same here on MacOS Catalina 10.15.7. The original invocation runs fine

    $ bash -c './redbean.com -vv'

Visiting http://127.0.0.1:8080/ in my web browser shows a nice redbean page with lobster graphic at http://127.0.0.1:8080/tool/net/redbean.html but then following usage instructions in another shell:

    $ echo 'hello' >index.html
    $ zip redbean.com index.html
      adding: index.html (stored 0%)
    $ ./redbean.com -vv
    Killed: 9
I blame my zip

    $ zip -v

Addition of index.html shrinks(!) redbean.com from size 204800 to size 204348, with changes starting from char 172938. That clearly corrupts the portable executable format.

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. Check out https://storage.googleapis.com/justine/cosmopolitan/index.ht... As far as I'm concerned, this is literal m…

Will this work if your code uses the C++ standard library ? Or is this just for pure C ?

The are a few options but all require some effort https://github.com/jart/cosmopolitan/issues/27

Nice job, Justine. This level of excitement reminds me of the early days of Linux. I think it has the potential to go far.

Author here. Thanks! I was deeply inspired when I read the source code to early versions of Linux and UNIX. The dream of that simple elegant power is something I'm hoping to restore for a new generation. All I'm doing to achieve that is simply standing on the shoulders of the giants who came before me.

After adding a new file with WinRAR, I get: EINVAL/err=87/errno:2/GetLastError:203 The parameter is incorrect. Probably the ZIP needs to be saved in a certain format.

Author here. The zip shouldn't need to be saved in any special format. If WinRAR is posing problems then please file an issue because I'd like to fix that. That error doesn't seem like something that would indicate executable corruption. I want to learn more.

Sure thing, will provide as much info as possible.

Yup, I get "Killed: 9" on macOS (Big Sur) too. I actually had some kind of problem (I think) with the original invocation:

For real. It's hard to grok cause there are no words to describe it. When people say that something is cross-platform, they usually mean a) that the software will build on multiple platforms b) there is some sort of vm which runs the executable (jvm, beam, wasm) This is the SAME binary. Running everywhere. Could be super-useful as an archival format for mission critical code. sqlite comes to mind. Maybe it's late at…

Author here. Thanks! I've added a new sponsor tier per your request. https://github.com/sponsors/jart

Do you have a direct paypall? Im not a fan of subscription services but Id like to support this.

Author here. Absolutely. I used to love Turbo Pascal and Delphi when I was younger. If Free Pascal uses GNU LD.BFD or LLVM LLD when it links programs, then all you'd need to do is is configure it to use cosmopolitan.a when linking system call functions like read(), write(), etc. See https://github.com/jart/cosmopolitan Another option is if Free Pascal wants to write all the system call support from scratch, then doin…

I love what you've produced here. I noticed that pthreads seems to be fail-stubbed for the time being, i guess it's a todo with tricky semantics? As for holding off on UI for the time being is probably the right thing to do, keeping with the minimal style planning on going for raw-x11,etc. However, as much as I personally love plain framebuffers (late 90s democoder myself), it'd be totally non-accessible for "plain"…

So far the only platform where I've managed to get threads to work has been Windows. I came pretty close to getting clone() on Linux working a few days ago. Threads are so hard because no API was ever defined for them in original UNIX and BSD, so therefore each modern system today does them in a completely different way. Another blocker is that not all operating systems let us modify segment registers which is something that the Linux compiler assumes is available for TLS. So it'd be a miracle if it ended up being possible to make threads work portably. fork() on the other hand was easy to get working on all platforms. I love fork() and vfork().

As for GUIs I'm still open to merging raw x11 support. One tricky issue is that we'd need to define a new API that veneers framebuffers, and so far Cosmopolitan has mostly refrained from defining novel interfaces, since the focus has been twiddling with low level magic numbers in order to make the textbook interfaces we already have work everywhere!
