Re: Building on a Mac

[James Hudson <jameshudson3010@gmail.com>]

Hello,

Thank you for your reply.

I can be (somewhat) flexible in how I configure. Do other configurations
work on the Mac? Or should I not even try to use these tools on the Mac and
move to Ubuntu?

A summary of what I changed from the defaults is:

   - Debug facilities → gdb
   - Debug facilities → ltrace
   - Debug facilities → strace


   - Companion tools → autoconf
   - Companion tools → automake


   - Operating system → Version of Linux → 4.19.21
   - Binary utilities → Version of binutils → 2.30
   - C-library → Version of glibc → 2.27
   - C compiler → Version of gcc → 7.4.0


The complete .config file is at

Regards,
Eric
