Description

This sets the compiler executable for the current script. It's a bit of a dodgy 'hack' but it works. The only problem is that the Test Installer button remains disabled after compiling has completed.


Save the below code as SetCompiler.nsh in your NSIS Include folder...

The Script

!verbose 0
!macro SetCompiler Path
 
 !verbose 0
 
 !ifndef "Compiler_Set"
 
  !define "Compiler_${Path}"
  !ifndef "Compiler_" & "Compiler_Default"
 
   !system 'IF EXIST "${Path}" echo !define "Compiler_Exists" \
    >"%TEMP%\SetCompiler.nsh"'
   !system 'IF NOT EXIST "${Path}" echo. >"%TEMP%\SetCompiler.nsh"'
   !include "$%TEMP%\SetCompiler.nsh"
   !system 'del "%TEMP%\SetCompiler.nsh"'
 
   !ifdef "Compiler_Exists"
 
    !verbose 4
    !echo "Compiler set to: ${Path}"
    !verbose 0
    !execute '"${Path}" /D"Compiler_Set" "${__FILE__}"'
    !error ""
 
   !else
    !verbose 4
    !error "${Path} compiler does not exist!"
    !verbose 0
   !endif
 
  !else
    !verbose 4
   !echo "Compiler set to: Default"
    !verbose 0
   !undef "Compiler_${Path}"
  !endif
 
 !else
  !undef "Compiler_Set"
 !endif
 
 !verbose 4
 
!macroend
!define SetCompiler "!insertmacro SetCompiler"
!verbose 4

Then place this in your script...

!include SetCompiler.nsh
${SetCompiler} "${NSISDIR}\makensis_8192.exe"

This sets the compiler to makensis_8192.exe (a copy of a [../download/specialbuilds MakeNSIS special build]).

If you want to use the default compiler (makensis.exe) just use...

${SetCompiler} Default

It also checks if the compiler executable exists before continuing.
