我尝试从
获取以下代码; The default installation directory
InstallDir $PROGRAMFILES\${PRODUCT_NAME}
到
!include x64.nsh
${If} ${RunningX64}
; The default installation directory
InstallDir $PROGRAMFILES\${PRODUCT_NAME}
${Else}
; The default installation directory
InstallDir $PROGRAMFILES64\${PRODUCT_NAME}
${EndIf}
我收到以下错误: -
!insertmacro: _If
Error: Can't add entry, no section or function is open!
Error in macro _RunningX64 on macroline 2
Error in macro _If on macroline 9
Error in script "C:\Users\yccheok\Desktop\mysoftware.nsi" on line 17 -- aborting creation process
我可以在if else块中设置InstallDir
的值吗?
答案 0 :(得分:9)
如果你需要动态$ InstDir,你根本不应该使用InstallDir,而是在.onInit中设置$ InstDir:
Installdir ""
!include LogicLib.nsh
!include x64.nsh
Function .onInit
${If} $InstDir == "" ; /D= was not used on the command line
${If} ${RunningX64}
StrCpy $InstDir "c:\foo"
${Else}
StrCpy $InstDir "c:\bar"
${EndIf}
${EndIf}
FunctionEnd
您当前的if else块没有任何意义,因为您在x64上选择了32位程序文件,在x86上选择了64位程序文件!在x86上使用$ PROGRAMFILES64是可以的,所以如果你总是想要“真正的”程序文件,你可以在所有平台上使用$ PROGRAMFILES64 ......
