Hi
all,
Since
some days I'm using sablecc to produce a small compiler.
I
experienced the following problem: if the target directory of the compiled
classes is different from the sources' directory, the lexer.dat file is
reported as corrupted or missing, even after it has moved to the classes
directory.
For
example:
1.
I produce my compiler sources in the directory 'src' (package
myPackage)
>
java -jar sablecc.jar src\myGrammar.grammar
2.
Compile and store the classes in directory
'classes'
>
javac -sourcepath src -d classes
src\myPackage\*.java
3.
move or copy the lexer.dat file
>
copy src\myPackage\lexer\lexer.dat
classes\myPackage\lexer
4.
I try to execute my compiler (after adding a myCompiler main
class..)
>
cd classes
>
java myPackage.myCompiler
The
file "parser.dat" is either missing or corrupted.
In
other words, seems like the lexer.dat file is sensible to the directory where
it has been created..
In
fact producing and compiling in the same directory doesn't give any trouble...
All
this at least on my configuration (on a win2000
system).
The
obvious workaround consists of produce the lexer.dat in the directory where
the classes are stored.
Please
note that this problem can be quite nerving in case you merge your produced
sources to a project developed with an IDE (like e.g. JBuilder in my case).
The produced classes are always stored on a separated directory from
sources..
I
excuse in advance if all this has already been reported
;-)
If
not I would appreciate any comment or
suggestion..
Kind
Regards,
Marco
