Я следую этому уроку , чтобы использовать cairo-rs для рисования чего-либо на изображении.Когда я запускаю свой код, я получаю очень длинную ошибку.Кажется, важными битами являются:
linking with "cc" failed: exit code: 1
и
ld: library not found for -lgobject-2.0
clang: error: linker command failed with exit code 1
Я установил Cairo через MacPorts, так что это не должно быть проблемой.Я скопировал файл Cargo.toml из учебника, за исключением обновленных пакетов:
[dependencies]
png = "0.12.0"
cairo-rs = {version = "0.4.1", features = ["png"]}
Я также пробовал использовать версии, перечисленные в учебнике, но получаю ту же ошибку.
Rust Issue 18610 , похоже, имеет аналогичную ошибку и предлагает установить libc-dev.Я не знаю, что это такое или почему это могло бы что-то исправить.
Я где-то видел, что это может быть конфликт имен, поэтому я изменил название своего проекта, чтобы не конфликтовать, но это не так.Т помочь.
Подробности
- Я нахожусь на стабильной Rust, я даже переустанавливал ее.
- MacOS High Sierra, версия 10.13.3 (17D47)
Полная ошибка
error: linking with `cc` failed: exit code: 1
