Re: [brlcad-devel] Integrating a new lemon/re2c parser in BRL-CAD logic

OK, so let's look at how to go at this. The problem is you're getting an empty csg_scanner.c file, which is obviously incorrect. That C file is generated by re2c, so let's take a look at what re2c is reporting by running make VERBOSE=1 : [100%] [RE2C][csg_scanner] Building scanner with brlcad/bu

Re: [brlcad-devel] Integrating a new lemon/re2c parser in BRL-CAD logic

Hello, As we previously discussed, I started modifying code in the src/conv/csg ( on top of your integrated patch, Cliff) to make it parse group() and identify some basic tokens. The problem I encountered and could not solve is the following: [ 91%] [ 91%] Building C object src/conv/csg/CMakeFile

Re: [brlcad-devel] Integrating a new lemon/re2c parser in BRL-CAD logic

Hello, As I mentioned in the last mail, I have been working on this simple calculator lemon parser, trying to have a better understanding of how lemon works and what are the key components when you build one. This example shows in an i

Re: [brlcad-devel] Integrating a new lemon/re2c parser in BRL-CAD logic

Hello, Firstly, thank you, Cliff, for you help with that csg integration patch, it really got disappointing not managing to make it work for so long. I added it to my svn copy and it compiled perfectly. Secondly, as Sean recommended, I started building a simple mathematical lemon parser in a incr

Re: [brlcad-devel] Integrating a new lemon/re2c parser in BRL-CAD logic

Andrei, Since the perplex/re2c/lemon setup is a bit obtuse from a build system perspective (which is my fault primarily) I've taken your patch and adapted it to give you what should be a minimal working setup. The attached patch, applied to the top level of a clean BRL-CAD trunk checkout, should

[brlcad-devel] Integrating a new lemon/re2c parser in BRL-CAD logic

Hello! As pointed out by Clifford, I have been looking over src/libgcv/wfobj CMAKE and file structure. After some research, i have found the following: it uses a perplex lexer and not a re2c, there is some re2c logic in BRL-CAD in other/stepcode/CMakeLists.txt but I don't understand it's purpose.
