math - ARM GCC 中对“日志”的未定​​义引用

Question

我在 ARM A53 上使用 ARM GCC 编译 lua，在链接期间我退出了很多与数学库相关的错误，例如：

我确实在链接期间添加了“-lm”选项，我可以在编译器主页中找到两个 libm.a，位于：

/ux/cad/tools/ARM/gcc-arm-9.2-2019.12-x86_64-aarch64-none-elf/./aarch64-none-elf/lib/libm.a /ux/cad/tools/ARM/gcc-arm -9.2-2019.12-x86_64-aarch64-none-elf/./aarch64-none-elf/lib/ilp32/libm.a

下面是链接命令（我用的是CMAKE，链接命令是CMAKE生成的）：/ux/cad/tools/ARM/gcc-arm-9.2-2019.12-x86_64-aarch64-none-elf/bin/aarch64-none-elf -gcc -g -nostartfiles -T /home/bruce/data/code/star2000e/project/star2000e/src/link_new.ld -Wl,-Map=star2000e.map -Wl,--gc-sections -specs=nosys.规格 -Wl,-cref -lm CMakeFiles/star2000e.elf.dir/project/star2000e/src/boot_el1.so CMakeFiles/star2000e.elf.dir/project/star2000e/src/main_star2000e.co CMakeFiles/star2000e.elf.dir/ project/star2000e/src/newlib_port.co CMakeFiles/star2000e.elf.dir/project/star2000e/src/vectors.co -o star2000e.elf sys/libsys.a 3rdparty/cmocka/libcmocka.a core/libcore.a bsp/ board_v2/libbsp.a -lm sys/libsys.a core/lib/littlefs/liblittlefs.a 3rdparty/json/libjson.a 3rdparty/lua/liblua.a 3rdparty/sfud/libsfud.a bsp/board_v2/libbsp.a 3rdparty /sfud/libsfud.一个驱动程序/star2000_soc/libdriver_star2000.a arch/arm_a55/libcpu_arm.a
