From 0fc37619574e697ae1ec6d1040f8a07670605f12 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Mon, 15 Aug 2022 15:19:34 +0200 Subject: [PATCH] libxt_coova: Use constructor instead of _init() The _init() function collides with a _init() function in crti.o. This results in the following error in OpenWrt: arc-openwrt-linux-gnu/bin/ld: libxt_coova.o: in function `_init': /lib/gcc/arc-openwrt-linux-gnu/11.3.0/crti.o:(.init+0x4): first defined here collect2: error: ld returned 1 exit status make[7]: *** [Makefile:22: libxt_coova.so] Error 1 Fix this by suing a constructor attribute instead. This function will still be called after the shared library was loaded.
