Embryo @VERSION@ Requirements: ------------- Must: libc libm WARNING: gcc compatibility!!! There seems to be some bug (or disagreement) between embryo and gcc 3.2.x where IEEE floating point format encoding does not "agree" with embryo's own hand-made tests. embryo_cc may not work if you compile using gcc 3.2.x. gcc 3.3.x is known to work fine. we are not 100% sure whose fault this is yet, so we won't be jumping up and down, but be warned - gcc 3.2.x does not agree with embryo. To view the API docs, run ./gendoc and view doc/html/index.html. OK a lot of people ask this. What is Embryo? Embryo is primarily a shared library that gives you an API to load and control interpreted programs compiled into an abstract machine bytecode that it understands. This abstract (or virtual) machine is similar to a real machine with a CPU, but it is emulated in software. The architecture is simple and is the same as the abstract machine (AMX) in the <a href=http://www.compuphase.com/pawn.htm>PAWN</a> language (formerly called SMALL) as it is based on exactly the same code. Embryo has modified the code for the AMX extensively and has made it smaller and more portable. It is VERY small. The total size of the virtual machine code AND header files is less than 2500 lines of code. It includes the floating point library support by default as well. This makes it one of the smallest interpreters around, and thus makes is very efficient to use in code. Embryo also uses the PAWN compiler from the same code base. This code has barely been touched and so suffers from lots of portability issues. It has been partially fixed and now works on both big and little endian but the code still need to be gone over and really cleaned up . It does work, but it's only just working. It has been called embryo_cc and compiled a subset of PAWN binary outputs. It does not support packed strings, variable alignment, or debugging output. It does not support many features of the full PAWN compiler because the Embryo AMX does not support these either. You will find the Embryo codebase to work much better on Linux (and BSD and MacOS X) and other UNIX operating systems as it has been developed and tested on them. IT is known to work on: gcc Linux (x86-32) gcc Linux (PPC) gcc MacOS X (PPC) And will likely work on more combinations. IT currently has problems on 64bit SPARC CPUs. Other 64bit systems are untested. It is the aim to fix the code so it works on all commonly used architectures (32, 64bit, big and little endian, alignment forgiving/unforgiving). So far 64bit support is the major issue. For more documentation please see the Language guide here: <a href=http://www.compuphase.com/pawn/pawn-lang.pdf>Pawn Language Booklet</a> This documents the PAWN language and is 100% relevant for Embryo and the syntax of files it can compile (.sma files). Any help is appreciated in helping clean and port this code, so feel free to send patches to the Enlightenment development lists. The main aim of Embryo is to provide an easy to use library for running compiled PAWN programs and giving them access to the calling program and any API it exports to the PAWN script. PAWN programs/scripts are completely sand-boxed. They cannot access any system or function calls other than the ones provided by the calling application to the Embryo API. This means a PAWN script cannot open or write to, delete or load files. It is fairly harmless and this also keeps Embryo small. This is a work in progress, so please be patient if things don't work for you - and patches and help in fixing it is very much appreciated. ------------------------------------------------------------------------------ COMPILING AND INSTALLING: ./configure make (as root unless youa re installing in your users directories): make install ------------------------------------------------------------------------------ BUILDING PACKAGES: RPM: To build rpm packages: sudo rpm -ta @PACKAGE@-@VERSION@.tar.gz You will find rpm packages in your system /usr/src/redhat/* dirs (note you may not need to use sudo or root if you have your own ~/.rpmrc. see rpm documents for more details) DEB: To build deb packages: tar zvf @PACKAGE@-@VERSION@.tar.gz cd @PACKAGE@-@VERSION@ dpkg-buildpackage -us -uc -rfakeroot cd .. rm -rf @PACKAGE@-@VERSION@ You will find all the debian source, binary etc. packages put in the directory where you first untarred the source tarball.
