Flex Build Documentation

XQilla uses a patched version of Flex for supporting unicode. If the lexer is modified (xqilla/src/lexer/XQLexer.l) then you will need the modified flex so that you can rebuild the lexer.

Simple Instructions for Flex

• Download the 2.5.4a version of Flex from the Flex project page (http://flex.sourceforge.net/∞)
• Decompress the Flex archive
• Save the patch file found at http://software.decisionsoft.com/pathanBuildInstructions.html#depth_lex∞ into the directory where Flex was decompressed to
• Run the patch by typing:

  patch -p1 < flex-2.5.4a-unicode-patch

• Build Flex folowing the instructions found in the INSTALL file:

  ./configure
  ./make

• You can now run the patched Flex on the XQLexer.l file:

  -Change into the directory that contains the XQLexer.l file:
  cd ~/xqilla/src/lexer
  
  -Run the modified version of Flex and not a Flex that may be in your path(the -U indicates unicode):
  ../../../flex*/flex -U XQLexer.l -o XQLexer_new.cpp

• Flex should take anywhere from 5 to 20 minutes to complete depending on the speed of your computer
• Replace XQLexer.cpp with the file you just produced XQLexer_new.cpp

Simple Instructions for Bison

• Still needs to be added.
