Same here in a Mac OS Sonoma M1 (but trying to build as x86_64 with ruby 3.2.3 in rvm)

Facing same issue on Mac OS Sonoma M2 @feolea how are you building as x86_64?

[taketo1113]

I success to install with below config in macOS Sonoma 14.3.1 (M1).

$ bundle config build.posix-spawn --with-cflags="-Wno-incompatible-function-pointer-types"

Using Rosetta @prabhanshu

[feolea]

Thank you so much @taketo1113 I was able to follow your idea and in my setup was able to install it using: (Sonoma 14.4 M1 RVM)

gem install posix-spawn -v 0.3.15 -- --with-cflags=\"-Wno-incompatible-function-pointer-types\"
