Post subject: | the message "unsupported relocation type 0" |
Q:We found the message "unsupported relocation type 0" appears when we load Linux kernel module which includes rwlock_init(). How can we solve this issue? A: 有2種可能性 (1)出現這個message通常是編譯driver所使用的toolchain,和 編譯kernel所使用的toolchain版本不一致。要改用同一個版本的toolchain來編譯。 (2)當您寫shared library時,裡面有一些code非pic(Position Independent Code), 解決的方法是編譯程式的時候,在gcc後面要加-fpic選項。 |
