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++ (3.4.4.3 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
   ./config

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
 
   PATH=$ALCHEMY_HOME/achacks:/home/Lee/flex:$PATH
   export PATH
 
   alc-on

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

Shortcuts

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

USEFUL TO KNOW

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 🙁 (?)
