***** BUILDING:
This program's build procedure is fairly standard. Try:
./configure
make
make install
Options to the configure script are up to you. For details, run:
./configure --help
Please report build problems at:
http://sourceforge.net/bugs/?func=addbug&group_id=4664
(yes, even non-Linux problems).
***** TIPS AND PROBLEMS:
- Try to use flex as the lexical analyzer. The lex scanner is now
separated from the flex version to allow the flex scanner to be
optimized. It's also a lot harder to diagnose and debug problems
without having full access to the particular platform and its version of
lex being used. flex is available everywhere --- AT&T lex is not.
- On Solaris, the native lex fails to catch our redefinition of YYLMAX
early enough, which leads to possible buffer overflows.
- On Linux systems (and possibly others) configure may fail if lex is
a synomyn for flex. To fix, do the following:
make distclean
./configure --with-flex
make
- On HP-UX several problems exist when using configure. Try the following
to solve this:
CFLAGS='-Ae -DYYCHAR_ARRAY' CURSES_LIBS=-lHcurses ./configure
- On Tru64, formerly known as Digital Unix, formerly known as DEC OSF/1,
the system-supplied libcurses causes cscope to terminate itself
immediately as it comes back to foreground after being suspended by
the user (Ctrl-Z). Using GNU Ncurses instead of OSF1 curses works
around the problem. According to the lynx and ncurses people, this
is a design problem of curses vs. signal handling, at the heart of it.
- Solaris 2.8 on Intel hardware may not work using the vendor's curses
implementation. Using the free NCurses should help.
- Some ancient Unix filesytems supported only 14 characters in
filenames. cscope no longer cares for that by default. If you want
to run it on such a system, #define the macro SHORT_NAMES_ONLY manually
(there's a definition in global.h you can uncomment).
