Following the instructions on https://www.emaculation.com/doku.php/compiling_sheepshaver_basilisk, when running ./configure --with-bincue for Basilisk II on MSYS2 using Windows 11, I get this error.

checking floating point format... configure: error: Unknown floating point format

Full Build Log: buildlog.txt

SheepShaver compiles fine. I think I need to install lib32-mpfr, but theres no such package in the official Arch repo or the AUR.

Unfortunately, I don't have an environment to test it on Windows 11.

MPFR is not required in x86 environment.

I found out what it was. I use optimized build flags, and enabling LTO is the reason for the error (-flto=auto). Is there a way that Basilisk II can support LTO by using the -flto=auto build flag?

shoober420 commented 6 days ago

I just compiled Basilisk II on my Arch Linux machine with the same build flags and did not encounter the error, so this is strictly in MSYS2 environments.

The word LTO reminded me that a similar problem occurred on Linux (#194). I have also applied it to Windows version, so try with the latest source.

Basilisk II now compiles successfully when -flto=auto is used, thank you.
