Вопрос:
Я не могу #include <errno.h> использовать заголовок в своем приложении GTK . Я пробовал как с GTK 2, так и с 3, все еще ошибка.
Если я не включу errno.h , он скажет, что он не был включен. Однако, если я это сделаю, ld завершится неудачей, сообщив, что ни одна функция из библиотек GTK не была включена.

То же самое для gtk2.
Я не нашел никакого решения в Интернете. Я запускаю Ubuntu 20.04 с gcc 9.3.0 и GTK из недавно установленных основных репозиториев Ubuntu apt.
РЕДАКТИРОВАТЬ: после закомментирования фрагмента кода, содержащего errno, я обнаружил, что это не проблема errno.h . Проблема в самом gtk. Но все равно получаю много ужасных предупреждений, и мне лень вставлять все соответствующие приведения типов.
Ответ №1:
РЕШЕНО!
Проблема в аргументах командной строки. Я ставил телегу впереди лошади. Флаги ВСЕГДА должны следовать за всеми другими аргументами.
Перемещение
$ gcc `pkg-config --libs --cflags gtk -3.0` -o winopa_launcher winopa_launcher.c
Для
$ gcc -o winopa_launcher winopa_launcher.c `pkg-config --libs --cflags gtk -3.0`
может решить проблему.
