Cross-compiling from MacOS

[Héctor Marqués]

Hi,
I am trying to follow https://wiki.minix3.org/doku.php?id=releases:3.2.1:developersguide:crosscompiling

But I am already stuck in: sh build.sh -U -mi386 -O ../build tools

It complains about "implicit declaration of function 'mi_vector_hash' is invalid in C99 [-Werror,-Wimplicit-function-declaration]".

Could anyone provide me some guidance on how to fix that error?

Thank you in advance!

Hello,
I didn't think anybody had reported a successful Mac OS build until I saw the table on that page.  Mind you I just realized why: that's an older version of the page geared towards Minix version 3.2.1.  Is that the version you're trying to compile or are you trying to compile the current master branch?  The latest version of the guide can be found here:

• https://wiki.minix3.org/doku.php?id=developersguide:crosscompiling (I see the table is now at the bottom of the page)
  

Please be aware that compilation tools have changed a bit in the last 5-10 years and issues have started to crop up.  It seems that compiling with older OSes (usually in a VM) may yield better results.  You can also compile within Minix, although that can be a slower process.  Sorry I can't be of more help at this time, but feel free to keep asking questions!

Thanks,

Hello stux,
thank you for your response :)

I was trying to compile master. I will attempt to follow the the guide of the url you passed with a VM.

Thanks!
