call !insertmacro twice in a same function

Hi,

I defined a macro to check versions of a file. For simplicity, the file is always put into two different fixed directories says "C:\MyApp1" and "C:\MyApp2"

I need to search through the file and get the version, so I wrote a macro:

code:


!macro CheckFileVersion DirToCheck IsRecursive VersionToCheck RET_Code

   ...

   ...

   ...

!macroend

When I call it on another macro, I do:

code:


!macro CheckAllDependencies RET_ResultCode

   !insertmacro CheckFileVersion "C:\MyApp1" "True" "1.0.0.1" $0

   !insertmacro CheckFileVersion "C:\MyApp2" "True" "2.3038.1102.13" $1

   ...

   ...

   ...

!macroend

When I tried to compile, it says:
Error: label "GoToNextDir:" already declared in function

Both of this macros reside on the same file (which is a common function file, CheckAppFunction.nsh). And will be included on my installer.

Any idea how to tackle this problem? Thanks for any help in advance.

Cheers :)

I found a way to get around this, with the help from this link:

Basically, I need to create a function inside a macro. So, in my case it is

code:


!macro CheckFileVersion_Macro UN

   Function ${UN}CheckFileVersion_Function

      Pop $R0    ;acting as DirToCheck

      Pop $R1    ;acting as IsRecursive

      Pop $R2    ;acting as VersionToCheck

      ...

      ...

      ...

      Push $R9   ;acting as RET_Code

   FunctionEnd

!macroend



!macro CheckFileVersion_Macro_Call _UN _DirToCheck _IsRecursive _VersionToCheck _RET_RESULTCODE

   Push ${_VersionToCheck}

   Push ${_IsRecursive}

   Push ${_DirToCheck }

   Call ${_UN}IsCPLEXDLLVersionOrNewerExists_Function

   Pop ${_RET_RESULTCODE}

!macroend



!macro CheckFileVersion

   !define CheckFileVersion '!insertmacro CheckFileVersion_Macro_Call ""'

   !insertmacro CheckFileVersion_Macro ""

!macroend

And when you want to use it, you can just simply do:

code:


!insertmacro CheckFileVersion

!macro CheckAllDependencies RET_ResultCode

   ${CheckFileVersion} "C:\MyApp1" "True" "1.0.0.1" $0

   ${CheckFileVersion} "C:\MyApp2" "True" "2.3038.1102.13" $1

   ...

   ...

   ...

!macroend

I hope, in the future, anyone who is learning how to use macro can take advantage of this post.

Cheers :)
