cmake分析错误：转义序列无效\o

我有很多类似的错误警报信息，例如：

 CMake Warning (dev) at cmake/common.cmake:5 (source_group):
    Syntax error in cmake code at

      C:/yumen/wxgisgdal-read-only/cmake/common.cmake:5

    when parsing string

      Header Files\\ogr\ogrsf_frmts

    Invalid escape sequence \o

文件

C:/yumen/wxgisgdal只读/cmake/common.cmake

为 就像是：

#add data
 macro(add_files_macro FPATH FGROUP)
     file(GLOB GDAL_AHHEADERS ${FPATH}/*.h  ${FPATH}/*.hpp)
     set(GDAL_HHEADERS ${GDAL_HHEADERS} ${GDAL_AHHEADERS})
     source_group("Header Files\\${FGROUP}" FILES ${GDAL_AHHEADERS})
     file(GLOB GDAL_ACSOURCES ${FPATH}/*.cpp ${FPATH}/*.cc ${FPATH}/*.c)
     set(GDAL_CSOURCES ${GDAL_CSOURCES} ${GDAL_ACSOURCES})
     source_group("Source Files\\${FGROUP}" FILES ${GDAL_ACSOURCES})
 endmacro()

以下是CMake错误信息：

 Configuring incomplete, errors occurred!

一个家伙告诉我，我应该添加这样的内容：

在

头文件\\ogr\ogrsf\u frmts

中，需要添加终止符

'\'

，如下所示：

"Header Files\\ogr\\ogrsf_frmts"

但是当我粘贴

common.cmake

文件内容行5时：

source_group("Header Files\\${FGROUP}" FILES ${GDAL_AHHEADERS})

---

头文件后的字符串替换为

FGROUP

宏，可能由CMake自动生成，因此我无法编辑它们。

发生错误，因为变量

${FGROUP}

的内容包含带有Windows样式分隔符的路径。CMake将这些字符视为转义字符

您应该将设置更改为a以避免出现这种情况。从

宏的文档中

：

请注意，宏的参数和值（如

ARGN

）不是通常的CMake意义上的变量。它们是字符串替换，就像c预处理器对宏所做的那样。如果需要真正的CMake变量，应查看

函数

命令

---

使用函数真的会有帮助吗？

add_files_macro

的第二个参数显然包含一个未经转换的反斜杠；CMake将以任何方式将其解释为转义序列。否-错误消息显示正在正确调用宏，因为引用的行位于宏体内部（在

source\u组

call的第5行）。如果字符串包含一个未转换的反斜杠，则错误将详细说明调用宏的点，而不是宏本身。更改为函数将解决此问题，因为它会以不同的方式处理其参数。好的，感谢您的澄清。我不知道函数和宏之间的这种特殊区别。嗯，你停止学习的那一天就是你死亡的那一天。你的意思是我将common.cmake文件内容更改为：#添加数据函数（添加文件）宏FPATH FGROUP文件（GLOB GDAL_AHHEADERS${FPATH}/*.h${FPATH}/*.h${FPATH}/*.hpp）集（GDAL_HHEADERS${GDAL_HHEADERS}${GDAL_AHHEADERS}）源组（头文件\\${GDAL${FGROUP}）文件（GLOB GDAL_ACSOURCES${FPATH}/*.cpp${FPATH}/*.cc${FPATH}/*.c）set（GDAL_CSOURCES${GDAL_CSOURCES}${GDAL_ACSOURCES}）source组（“source Files\\\${FGROUP}”Files${GDAL_ACSOURCES}）endfunction（）
