+5. Вирусов здесь нет. У вас либо чья-то сборка, либо ваш антивирус давно пора отправить на покой. Антивирусы в основном жалуются на upx и windivert, которые убраны НЕ будут. Не согласны - удаляйте софт. За агрессивные наезды "почему автор распространяет вирусы" молча схватите бан.

 Все означенное обсуждать в дискуссиях или на форумах.

+Работа blockcheck в android shell не поддерживается, но имея рута можно развернуть rootfs какого-нибудь дистрибутива linux.

+Если компа нет, то развертка chroot - единственный вариант, хотя и неудобный.
 Подойдет что-то легковесное, например, alpine или даже openwrt.
 Если это не эмулятор android, то универсальная архитектура - arm (любой вариант).
 Если вы точно знаете, что ОС у вас 64-разрядная, то лучше вместо arm - aarch64.
+Выяснить архитектуру можно командой `uname -a`.

Konstantin Kharlamov	6fe9471077	Use `-march=native` when building from install_easy.sh install_easy.sh is used for local installation, which implies that if it invokes make, the binaries are not being cross-compiled. That allows us to pass `-march=native` to make sure the binaries are optimized for the current CPU. We prepend `-march=native` to CFLAGS to make sure that if a user sets CFLAGS with a distinct `-march` option, ours will get overwritten.	2024-12-24 18:42:16 +03:00
