From ed6a9513157f54894629d8dfa8890df0245505ec Mon Sep 17 00:00:00 2001 From: Dmitry Chestnykh Date: Sun, 11 Feb 2024 09:29:54 +0300 Subject: Add extra `-shared` to link.so command. While compiling OpenADK I discovered that there may be a case where UCLIBC_EXTRA_LDFLAGS contains `-fpie -pie`. Linker ignores `-shared` if `-pie` flag is passed after and produces an executable binary instead of shared object. This leads to linking failure because `ld-uClibc.so.1` becomes executable instead of shared object. `ld-uClibc.so.1` is used as one of the inputs when linking of libc.so.1 and linking proccess fails. To prevent this issue we need to pass extra `-shared` flag in `link.so` target command after all other flags to overwrite `-pie` effect.
