Ho-To: Install Alchemy

For those of you who tried but didn't succed, I found some straigthforward instructions for this.

Setup Hell:

Install cygwin to "c:\cygwin" - make sure to check boxes to install Perl, "Archive" (ZIP), and Devel/gcc:g++ ( presumably) (is Perl necessary?)
Copy the alchemy directory to: c:\cygwin\home\Lee
Copy the flex sdk bin dir from c:\program files\etc to "c:\flex" (to avoid paths with spaces in it!)
Run the alchemy config script once:

   run cygwin
   cd alchemy

Edit the textfile "C:\cygwin\home\Lee\alchemy\alchemy-setup" and uncomment and edit line 22 to: add "export ADL=c:\flex\adl.exe"

Edit .bashrc (in C:\cygwin\home\Lee)

   echo "LEE PROFILE"
   export FLEX_HOME=~/flex
   export ALCHEMY_HOME=~/alchemy
   # "This should be added before your PATH is modified" !!
   source /home/Lee/alchemy/alchemy-setup
   export PATH

Do this (just once, I think):

   cd $ALCHEMY_HOME/bin
   ln -s llvm-stub llvm-stub.exe

Compiling a SW:

CD to the directory with the source
Always do "alc-on" before compiling, cuz it doesn't work without it even though i added it to the startup (dunno)

    gcc stringecho.c -O3 -Wall -swc -o stringecho.swc
    -- should give you a swc.

Import the swc into your flex builder 4 project and make sure compiler targets SDK v4


alc-home - takes you to the Alchemy install folder.
alc-on - puts Alchemy gcc toolchain replacements at the front of your path.
alc-off - restores original path.
alc-util - shows you various Alchemy-related environment vars


which gcc - tells you which gcc it will use (should be the one in the achacks dir)
ln - links shit
rm - deletes links as well as files

Ugh: Make sure to do "alc-on" and "alchemy-setup" even though you put it in the startup script :( (?)

  1. Hi,
    I am new to Adobe Alchemy, I have a problem in compiling c file into swc using Alchemy gcc under cygwin. I have configured everything under Cygwin and environment paths also. But when I run the gcc command on the c file with the parameters “gcc test. -03 -Wall -swc -0 test.swc” it doesn;t compile the c file into swc file and it doesn’t even produce errors.
    Please help me to know what is wrong or what is going on in it?

    Try to install all Perl packets. It solves my same problem.

  3. Nice tutorial. i tried to setup the Alchemy at my system

    1. :No Such file or directorylchemy-setup
