See the manual for m19 here (warning: portuguese)

Requirements

• Linux machine
• flex(tested on 2.6.4), byacc(tested on 1.9), yasm(tested on 1.3.0), GNU ld(version 2.31.1)

Features

• This compilers compiles to 32 bit architectures
• The language is compatible with C
• The cdk tarball present in this repo is the skeleton of the compiler
• The rts tarball present in this repo provides libraries for linking

How to Run

Compile the compiler

Unpack the cdk and rts tarballs, and run "make install" in each one. This will create a directory in the HOME folder, "compiladores/root" where the libraries will be copied to. You can always change this by editing the Makefiles top section (it has to be consistent with the m19 Makefile).

tar xf Libcdk14-201902132207.tar.bz2
tar xf Librts4-201602111900.tar.bz2
cd libcdk14-201902132207
make install
cd ../librts4-201602111900
make install

In m19/, run "make":

cd m19
make

The m19 binary will now be inside m19/

Compile m19 programs

Let main.m19 be our m19 code. First, generate assembly:

/path/to/m19 main.m19 

This will place a file named "main.asm" in the main.m19 location. Now, use yasm to generate binary code (32 bit elf):

yasm -felf32 main.asm

It outputs "main.o". Now we just have to link it with ld:

ld -m elf_i386 -o main main.o -L/path/to/rts/lib -lrts

main is your compiled m19 program. If you wish to use several .m19 files, you just need to link them all with the ld command:

ld -m elf_i386 -o main file1.o file2.o file3.o -L/path/to/rts/lib -lrts

XML

If you wish to generate the xml tree of the program, do:

/path/to/m19 main.m19 --target xml

And it outputs "main.xml"

Test

Run ./test.sh. Tweak the script variables as needed.
