Hi all, There is a test for prebuild Rust library link with UEFI C code in GCC build as below. But I will encounter some build problems. Case 1: prebuild Rust library with aarch64-unknown-uefi target command, it will encounter "error adding symbols: file format not recognized". Case 2: I tried another similar target aarch64-unknown-none which also supports no-std lib, it will successfully link in GCC build. However, when I use alloc::vec::Vec and alloc::string::String lib in Rust library, the build will encounters build error that WriteSections64(): AARCH64 relative relocations require identical ELF and PE/COFF section offsets. But they won't happen in Window build environment. Does anyone have any experience about this problem? Build Target on Arm VirtQemu Platform * ArmVirtPkg/ArmVirtQemu.dsc Prebuild library in Rust * cargo build --release --target aarch64-unknown-uefi * cargo build --release --target aarch64-unknown-none EKD2 build environment in Ubuntu * gcc-aarch64-linux-gnu Thanks and regards, Jared Pan -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
