build: error with meson 0.60: "../meson.build:277:2: ERROR: Function accepts only strings, integers, lists, dictionaries and lists thereof."

graphene 1.10.8 meson 0.60 i am cross compiling (on windows, using msys2 and the mingw-w64 toolchain)

error: ../meson.build:277:2: ERROR: Function accepts only strings, integers, lists, dictionaries and lists thereof.

no error with meson 0.55.3 (the minimal version requested in meson.build)

It would be useful for debugging purposes if you checked what's at line 277 of the meson.build file.

Current tip of the main development branch has a message() function, which takes more than strings, integers, lists, and dictionaries: https://mesonbuild.com/Reference-manual_functions.html#message

Could you check what happens if the message() is replaced with:

  message('Cross-building, assuming IEEE 754 division: @0@'.format(ieee754_float_div))

This used to be undocumented and an accidental side effect of leaky python implementation details casting.

It's officially supported since https://github.com/mesonbuild/meson/commit/6298e2907082aff0763a09165c6c2841ac869e2d and was backported to 0.60.1

So,

graphene 1.10.8 meson 0.60 i am cross compiling (on windows, using msys2 and the mingw-w64 toolchain)

You're using something a lot more specific than Meson 0.60, you're using 0.60.0 and not 0.60.1, please specify this next time.

well, I specified the version of graphene

Current tip of the main development branch has a message() function, which takes more than strings, integers, lists, and dictionaries: https://mesonbuild.com/Reference-manual_functions.html#message

Could you check what happens if the message() is replaced with:

  message('Cross-building, assuming IEEE 754 division: @0@'.format(ieee754_float_div))

works with meson 0.55.3, 0.60.0 and 0.60.1

output:

Message: Cross-building, assuming IEEE 754 division: true

Since Meson has been fixed, and the 0.60.* branch is really old at this point, let's close this.
