Thanks, that explains it!
After manually fixing the “-a”
I can correctly generate the parser sources.
Do you know if this LPG bug has been
reported somewhere? I searched for it in the project’s sourceforge
tracker but was not able to find it.

Subject: Re: [cdt-dev] LR parser
and LPG version
There is a bug in the LPG generator that causes it to
sometimes output "-a" when it should output "-1". The
workaround is to manually edit the generated files by replacing "-a" with
"-1".
The required LPG version is 1.1.

[cdt-dev] LR parser
and LPG version
|
Hello,
I am experimenting with extending the new LR
parser to recognize custom
extensions to the CDT language.
I can successfully build and run the checked out
java files, but I am
not able to correctly generate them from the .g
grammar files - the
files will contain syntax errors.
I checked out the following plugins from CVS
net.sourceforge.lpg.lpgjavaruntime
org.eclipse.cdt.core.lrparser
org.eclipse.cdt.core.lrparser.sdk
org.eclipse.cdt.core.lrparser.sdk.feature
org.eclipse.cdt.core.lrparser.tests
I also downloaded the LPG 1.1 distribution from
sourceforge
http://sourceforge.net/projects/lpg/files/lpgdistribution/LPG-V1.1/lpgdi
stribution-05-16-06.zip/download
in order to obtain the parser generator executable
(lpg.exe).
I have set up the lpg_exe and lpg_template ant
properties to point to
the lpg.exe and the
org.eclipse.cdt.core.lrparser/grammar/templates
folder, respectively.
I can run the build.xml script and generate the
java sources, but the
files created will contain syntax errors (like a
"-a" instead of a "-1"
in parser tables). I have also tried to use the
lpg executables 2.0 but
they will generate even more errors.
What is the lpg version which has been used to
build the parser sources
in the lrparser plugin?
Thanks for your help,
/Mario
