nsis error: resolving install function

[cx08]

Sample script:

code:
(--helpers.nsh--)

!define CreateSymbolicLinkFolder "!insertmacro CreateSymbolicLinkFolder"

!ifdef CreateSymbolicLinkFolder_

    Function CreateSymbolicLinkFolder_

        Exch $0   ; _TARGET

        Exch 1

        Exch $1   ; _JUNCTION

        IfFileExists "$0" 0 done

        ${GetParent} "$1" $R0

        CreateDirectory "$R0"

        System::Call "kernel32::CreateSymbolicLinkW(w `$1`, w `$0`, i 1) i .s"

        done:

        Pop $R0

        Pop $1

        Pop $0

    FunctionEnd

!endif

!macro CreateSymbolicLinkFolder _JUNCTION _TARGET

    !define CreateSymbolicLinkFolder_

    Push "${_JUNCTION}"

    Push "${_TARGET}"

    Call CreateSymbolicLinkFolder_

!macroend



(--sample.nsi--)

!include "helpers.nsh"

...

${CreateSymbolicLinkFolder} "$APPDATA\SOMEPATH" "$EXEDIR\Data"

Nsis error:
Error: resolving install function "DeleteLinkOrFolder_" in function "Clean"
Note: uninstall functions must begin with "un.", and install functions must not

How can i do fix the this?

In this code:

code:
!define CreateSymbolicLinkFolder "!insertmacro CreateSymbolicLinkFolder"

!define CreateSymbolicLinkFolder_

!ifdef CreateSymbolicLinkFolder_

    Function CreateSymbolicLinkFolder_

        Exch $0   ; _TARGET

        Exch 1

        Exch $1   ; _JUNCTION

        IfFileExists "$0" 0 done

        ${GetParent} "$1" $R0

        CreateDirectory "$R0"

        System::Call "kernel32::CreateSymbolicLinkW(w `$1`, w `$0`, i 1) i .s"

        done:

        Pop $R0

        Pop $1

        Pop $0

    FunctionEnd

!endif

!macro CreateSymbolicLinkFolder _JUNCTION _TARGET

    Push "${_JUNCTION}"

    Push "${_TARGET}"

    Call CreateSymbolicLinkFolder_

!macroend

if i modify the script like this and if i don't need the macro "CreateSymbolicLinkFolder", nsis give me a warning:
install function "CreateSymbolicLinkFolder_" not referenced - zeroing code

I assume this is the same question as you posted on SO? It is a bit hopeless when the errors are in "DeleteLinkOrFolder_" or "Clean" and you don't even show us what those functions look like!

Sorry, the correct source code:

Sample nsis script:

code:
(--helpers.nsh--)

!define CreateSymbolicLinkFolder "!insertmacro CreateSymbolicLinkFolder"

!ifdef CreateSymbolicLinkFolder_   ; <--- always false

    Function CreateSymbolicLinkFolderFunc

        Exch $0   ; _TARGET

        Exch 1

        Exch $1   ; _JUNCTION

        IfFileExists "$0" 0 done

        ${GetParent} "$1" $R0

        CreateDirectory "$R0"

        System::Call "kernel32::CreateSymbolicLinkW(w `$1`, w `$0`, i 1) i .s"

        done:

        Pop $R0

        Pop $1

        Pop $0

    FunctionEnd

!endif

!macro CreateSymbolicLinkFolder _JUNCTION _TARGET

    !define CreateSymbolicLinkFolder_   ; <--- not work...

    Push "${_JUNCTION}"

    Push "${_TARGET}"

    Call CreateSymbolicLinkFolderFunc

!macroend



(--sample.nsi--)

!include "helpers.nsh"

...

Function Clean

    ${CreateSymbolicLinkFolder} "$APPDATA\SOMEPATH" "$EXEDIR\Data"

FunctionEnd

Section "Main"

    Call Clean

SectionEnd

Nsis error:
Error: resolving install function "CreateSymbolicLinkFolderFunc" in function "Clean"
Note: uninstall functions must begin with "un.", and install functions must not

How can i define CreateSymbolicLinkFolder_ correctly in macro CreateSymbolicLinkFolder?
The "!ifdef CreateSymbolicLinkFolder_" code is to avoid nsis warning, when i don't need to call the macro CreateSymbolicLinkFolder:
install function "CreateSymbolicLinkFolder_" not referenced - zeroing code

CreateSymbolicLinkFolder_ is not defined at the top before the !ifdef so the function is never created. Define it before the !include or check my answer on SO for a better way to do this...
