如何为 6502 CPU (C64) 设置 CMake 交叉汇编工具链？

Question

我正在尝试为名为 TMPx.

的 Commodore 64/6502 交叉汇编器设置一个尽可能可重复使用的 cmake 构建系统

我的问题是：

• 我如何让 CMake [尝试] 检测并设置 tmpx 或 TMPx.exe 可执行文件和正确的路径，在不同的指定位置，具体取决于主机平台？
  • 而如果也有可能，下面列出的./cmake/模块中，哪个是这样的search/find？
• 有什么方法可以让 cmake . 检测并列出 TMPX 版本，而不是显示 ：

  -- The ASM_TMPX compiler identification is unknown

除此之外，非常感谢其他意见和建议。

（这是我的 git repo 和下面的文件）

我的./CMakeLists.txt

CMAKE_MINIMUM_REQUIRED(VERSION 3.14)
set(CMAKE_SYSTEM_NAME "C64")
set(CMAKE_SYSTEM_PROCESSOR 6502)

LIST(APPEND CMAKE_MODULE_PATH "${CMAKE_BINARY_DIR}/cmake")
#TODO: Try to move this into one of the cmake/ modules..
SET(CMAKE_ASM_TMPX_COMPILER "${CMAKE_BINARY_DIR}/tools/TMPx_v1.1.0-STYLE/linux-x86_64/tmpx")

PROJECT(test001 ASM_TMPX)

通过关注 this guide from the CMake wiki 到目前为止，我已经获得了以下即将完成和半工作的 cmake 模块：

./cmake/CMakeASM_TMPXInformation.cmake:

SET(ASM_DIALECT "_TMPX")

SET(CMAKE_ASM${ASM_DIALECT}_SOURCE_FILE_EXTENSIONS ms;s;asm)


#Set any default arguments here
#TODO: remove the nasm args
IF(UNIX)
    SET(CMAKE_ASM_TMPX_COMPILER_ARG1 "-f elf")
ELSE(UNIX)
    SET(CMAKE_ASM_TMPX_COMPILER_ARG1 "-f win32")
ENDIF(UNIX)

# This section exists to override the one in CMakeASMInformation.cmake
# (the default Information file). This removes the <FLAGS>
# thing so that your C compiler flags that have been set via
# set_target_properties don't get passed to TMPx and confuse it.
IF(NOT CMAKE_ASM${ASM_DIALECT}_COMPILE_OBJECT)

    #TODO: Change nasm args to correct tmpx arguments
    SET(CMAKE_ASM${ASM_DIALECT}_COMPILE_OBJECT "<CMAKE_ASM${ASM_DIALECT}_COMPILER> -o <OBJECT> <SOURCE>")

ENDIF(NOT CMAKE_ASM${ASM_DIALECT}_COMPILE_OBJECT)

INCLUDE(CMakeASMInformation)
SET(ASM_DIALECT)

./cmake/CMakeDetermineASM_TMPXCompiler.cmake:

SET(ASM_DIALECT "_TMPX")

IF(UNIX)
    SET(CMAKE_ASM${ASM_DIALECT}_COMPILER_LIST ${_CMAKE_TOOLCHAIN_PREFIX}tmpx)
ENDIF()

# TODO: Properly determine exen for other host platforms
# (The Windows exe would be 'TMPx.exe' but possibly 'tmpx.exe' or 'TMPX.EXE')

INCLUDE(CMakeDetermineASMCompiler)

SET(ASM_DIALECT)

./cmake/CMakeTestASM_TMPXCompiler.cmake:

###
# From original template:
# This file is used by EnableLanguage in cmGlobalGenerator to
# determine that the selected ASM-ATT "compiler" works.
# For assembler this can only check whether the compiler has been found,
# because otherwise there would have to be a separate assembler source file
# for each assembler on every architecture.
###

set(ASM_DIALECT "_TMPX")
include(CMakeTestASMCompiler)
set(ASM_DIALECT)

./cmake/Platform/C64.cmake:

MESSAGE("-¤# Building for Commodore 64 platform! #¤-")

#this does not seem to work
#SET(CMAKE_ASM_TMPX_COMPILER "${CMAKE_BINARY_DIR}/tools/TMPx_v1.1.0-STYLE/linux-x86_64/tmpx")

set_property(GLOBAL PROPERTY TARGET_SUPPORTS_SHARED_LIBS FALSE)

Answer 1

在使用 CMake 的 'MESSAGE()' 命令仔细检查后，我想我至少得到了第一个问题的答案； ./cmake/CMakeDetermineASM_TMPXCompiler.cmake 是第一个要 运行 （并且只在第一个 'cmake .'） 当例如

PROJECT(test001 ASM_TMPX) #asm_tmpx denoting the <lang>_<dialect>

设置在./CMakeLists.txt

就我而言，'cmake .' 的 运行 订单似乎是：

1. ./cmake/CMakeDetermineLANG_DIALECTCompiler.cmake (运行s 仅在初始 'cmake .')

2. ./cmake/Platform/CMAKE_SYSTEM_NAME.cmake ( 运行s 每 'cmake .')

   Note: This relies on e.g SET(CMAKE_SYSTEM_NAME "C64") having been set in CMakeLists.txt; CMake will then look for e.g ./cmake/Platform/C64.cmake

3. ./cmake/CMakeLANG_DIALECTInformation.cmake (运行s 每 'cmake .')

4. ./cmake/CMake测试LANG_DIALECTCompiler.cmake (运行s 仅在初始 'cmake .')

所以我猜 CMakeDetermineLANG_DIALECTCompiler.cmake 是所有位置检测的地方汇编器可执行文件的提取，以及汇编器版本的任何提取、它的命令行参数等，都可以而且需要执行。
