Problem when compiling the OpenSCAD.

[mrhdias]

Hi,

I can not compile the OpenSCAD, because of the following error:

yacc -d -p parser -b parser src/parser.y
yacc: e - line 27 of "src/parser.y", syntax error
%expect 1 /* Expect 1 shift/reduce conflict for ifelse_statement - "dangling
else problem" /
^
make: ** [parser_yacc.h] Error 1

I've tried the latest version and the version from the github and does not
compile on both.

Anyone have suggestions for solving this problem?

My OS is Gentoo Linux - AMD64

Thanks,

Henrique Dias

I've had reports that some Linux distributions ship with a version of yacc/bison where the %expect statement is not supported. The mailing list has a number of Linux users lingering, they might give better response to this.

Hi kintel,

I just found a solution but do not know if it's the right one.
I replaced the yacc by the bison parser in Makefile and work.

Steps to build the OpenSCAD successfully:

git clone --depth=1 git://github.com/openscad/openscad.git
cd openscad
qmake
cp Makefile Makefile.org
nano -w Makefile <-- Replace the yacc parser by the bison (find the line 338).
make

Comparing the original Makefile, with the new Makefile:

diff -u Makefile.org Makefile
--- Makefile.org 2011-01-28 23:10:50.000000000 +0000
+++ Makefile 2011-01-28 23:11:18.000000000 +0000

   rm -f parser_yacc.h parser_yacc.cpp
   mv -f parser.tab.h parser_yacc.h

Thanks for your help.

I think the fix will be to use bison explicitly everywhere.

This should be fixed by know (updated build system)
