/* THE PRECOMPILED BINARIES */ 

... may work for you, or not, depending on your system's details. 

-- On my mac the plugin (allsubsetsmeta_osx.plugin) works fine for OS 10.5. through 10.7.4. 

-- On Windows, the plugin (allsubsetsmeta_win.plugin) works on 32 bit XP (home something or other) and 32 bit Windows 7. I do not have a 64 bit machine, so dunno whether it works there. Should work. 

-- I did not compile a *nix plugin. I doubt Unix users would need a binary.  

-- If the binaries do not work for you, then do try compile from source before shooting me an email (thomas_trikalinos [at] REMOVETRASHCAPS brown [dot] edu).  
Compiling should be easy -- the only dependency is the (open source and free) GNU Scientific Library (GSL) -- just because I got lazy and used a couple of functions from there.  

-- To install: 
Put allsubsets.ado, allsubsetsmeta_[win|osx].plugin, and allsubsets.hlp somewhere on the Stata path (for more info, from within Stata _help adopath_). 

-- To test: 
Save test.do and data.txt on the Stata path; run test.do.

/* COMPILING */

/* Mac OSX */ 

The header stplugin.h and the file stplugin.c must be in the current directory. 
Then:

gcc -bundle -DSYSTEM=APPLEMAC  -I. -I/sw/include -L/sw/lib stplugin.c allSubsetsMeta.c -o allsubsetsmeta_osx.plugin -lm -lgsl -lgslcblas

and the C plugin is ready. [Change the -I flags appropriately to point to the GSL library in your system.]

/* Windowz*/
I compiled the uploaded binary in VS 2008; if you use gcc through cygwin (at least for older cygwin installations that allowed crosscompilation to mingw):

gcc -shared -I. stplugin.c allSubsetsMeta.c -o allsubsetsmeta_win.plugin -lm -lgsl -lgslcblas
