Instead of using -no-pie, I tried to replace crtbegin.o with crtbeginS.o (and respective crtend.o to crtendS.o) Is it a correct fix? After this the simple hello world compiles and runs properly. Now I am trying to compile bigger project (sqlite3 library) with variable success. In order to make it compile I was forced to use "-fno-stack-protector" option. I am not sure whether or not this is a MUSL issue. The errors was like: sqlite3.c:(.text+0x106f): undefined reference to `__stack_chk_fail_local' Is the used workaround correct? Also, after compiling with -O3 the library compiles but not working then. Which is strange, but probably an issue for the sqlite mailing list. -- John Found
