Error while compiling Graphviz open source application

[vthiru]

Dear Admins,

I am trying to compile Graphviz open source application on HP-UX B.11.11. I am getting the following error:

pathpath.c: In function 'pathpath':
pathpath.c:72: error: 'F_OK' undeclared (first use in this function)
pathpath.c:72: error: (Each undeclared identifier is reported only once
pathpath.c:72: error: for each function it appears in.)
make[3]: *** [pathpath.lo] Error 1
make[3]: Leaving directory `/usr/local/graph/graphviz-2.12/lib/ast'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/usr/local/graph/graphviz-2.12/lib'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/local/graph/graphviz-2.12'
make: *** [all] Error 2

Thanks in advance.

Regards,
Thiru

What header is suppose to define F_OK? If you don't know, you could try searching /usr/include and /usr/include/sys/. You may be including the right header but if you don't compile with the right -D flags, it may be skipped.
