I'm trying to create a Bison/Flex project where the Bison/Flex output files are in the src/ folder, with the rest of my source code.

I modified an existing C/C++ Application Project by looking at the Lex/Yacc sample project configurations.xml. The Lex/Yacc project has the following entry in its configurations.xml:

<customToolOutputs>y.tab.c y.tab.h</customToolOutputs>

I wanted my files to be named parser.c and parser.h and to reside in the src/ folder, so I changed this line in my C/C++ project configurations.xml to:

<customToolOutputs>src/parser.h src/parser.c</customToolOutputs>

But it appears that Makefile-Debug.mk and Makefile-Release.mk have the following target generated:

src/parser.h src/parser.c: src/grammar.y
     ${MKDIR} -p src/parser.h src
     @echo Running bison...
     bison --defines=src/parser.h -o src/parser.c src/grammar.y

Notice the mkdir command creates the directory "src/parser.h", instead of just "src". This causes bison to complain that it cannot create the "src/parser.h" file because it already exists as a directory.

Below are the messages I get when I select Build:

"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf

BUILD FAILED (exit value 2, total time: 2s)

I can get it to compile if the I run rmdir src/parser.h/ just before running bison.
I have attached the C/C++ project to this issue report.
