在 cmake 中编译链接器脚本 - 找不到目标文件（嵌入式项目）

【中文标题】在 cmake 中编译链接器脚本 - 找不到目标文件（嵌入式项目）

【问题描述】：

我的问题是我想从这个项目的普通 makefile 做一个 cmake 文件： https://github.com/brianwiddas/pi-baremetal

我创建了 CMakeLists 文件，但在链接项目时遇到了问题。在 make 命令之后，我有一个这样的错误：

Linking C executable rpi-0.1.elf
/usr/bin/../lib/gcc/arm-none-eabi/4.9.3/../../../../arm-none-eabi/bin/ld: cannot find start.o
collect2: error: ld returned 1 exit status
make[2]: *** [rpi-0.1.elf] Błąd 1
make[1]: *** [CMakeFiles/rpi.dir/all] Błąd 2

链接器代码片段：

MEMORY

    initsys : org = 0x8000, len = 1M
    kernel : org = 0xf0000000, len = 1M
    data : org = 0xc0000000, len = 1M

SECTIONS

    /* Initial section, loads/runs at 0x8000 */
    .init : 
        start.o(.text* .data* .bss* .rodata*)
        initsys.o (.text* .data* .bss* .rodata*)
     >initsys

    //the rest of code in SECTION

我意识到cmake创建带有“.c.obj/.s.obj”扩展名的目标文件，与这个带有“.o”扩展名的makefile比较，我在链接器代码中对其进行了更改，但现在错误是：

cannot find start.s.obj

现在我不知道出了什么问题。可能是因为在 makefile 项目中，源代码文件和目标文件在同一个文件夹中。 Cmake 在另一个文件夹中创建目标文件，在我的情况下：

source files folder - ../Projekt/code
object files folder - ../Projekt/build/CMakeFiles/rpi.dir/code

也许链接描述文件看不到目标文件，因为它们在另一个文件夹中。 build 文件夹由 cmake 自动创建。

这是我的 CMakeLists.txt 文件：

## Minimal cmake version
cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

## Project name
project(rpi C CXX ASM)

## Project version
set($PROJECT_NAME_version "0.1")

## Project options

## Creation of the necessary definitions

    add_definitions(-DDISABLE_NEWLIB_SUPPLIED_SYSCALLS)
endif (DISABLE_NEWLIB_SUPPLIED_SYSCALLS)

add_custom_command(TARGET $PROJECT_NAME COMMAND $CROSS_COMPILER_PREFIXobjcopy $CMAKE_BINARY_DIR/$PROJECT_NAME-$$PROJECT_NAME_version.elf -O binary $CMAKE_BINARY_DIR/$PROJECT_NAME-$$PROJECT_NAME_version.img)

和toolchain-raspberry-pi.cmake文件：

## Determination of the operating system on which the program is designed
set(CMAKE_SYSTEM_NAME Generic)

## The term architecture on which the program is established
set($PROJECT_NAME_architecture raspberry-pi)

## Prefix tools used for cross-compiling
set(CROSS_COMPILER_PREFIX arm-none-eabi-)

## Compilers that will be used.
include (CMakeForceCompiler)
cmake_force_c_compiler($CROSS_COMPILER_PREFIXgcc GNU)
cmake_force_cxx_compiler($CROSS_COMPILER_PREFIXg++ GNU)

如何修复此错误以及为什么 cmake 不创建带有“.o”扩展名的目标文件，并且与源代码位于同一文件夹中？ 请帮忙。

解决方案：

在链接器脚本中，我在 start.s.obj/initsys.c.obj 之前添加 *，如下所示：

*start.s.obj (.text* .data* .bss* .rodata*)
*initsys.c.obj (.text* .data* .bss* .rodata*)

【参考方案1】：

你能在链接器文件中尝试*start*.o(.text* .data* .bss* .rodata*)吗？

PS：我无法编译您的项目。我猜您正在使用 arm-none-eabi-* 工具链进行交叉编译。你如何覆盖默认编译器？

【讨论】：

你使用的是windows还是linux平台？如果上述解决方案不起作用并且您正在使用 Windows 尝试将 *.start*.o 替换为 *start*.obj

嗨，感谢您的帮助，我添加 * 并且现在可以工作了：] 我通过将此行添加到 toolchain-raspberry-pi.cmake 文件来覆盖默认编译：set(CROSS_COMPILER_PREFIX arm-none-eabi-)
