* Partial update to README (which still needs work for this
release!): (1) use of configure corrected for new script,
(2) "make gdb.dvi" and "make gdb.info" mentioned.
Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
* symtab.c (lookup_symbol): Don't complain right off about
no debug symbols; use the misc function vector first.
(list_symbols): Use misc function vector to find symbols
that don't have debug info, and print them.
(find_pc_symtab): Temporarily avoid fatal() when psymtab
PC range doesn't match symtab PC range, as it does on the
MIPS because our symtab reading isn't perfect.
* dbxread.c (dbx_symfile_read): Make warning about
"no debug symbols" slightly nicer.
* source.c (select_source_symtab): If "main" symbol exists,
but decode_line_spec can't find line info, don't just return
a zero; try other source symtabs or give an error.
* mipsread.c (parse_partial_symbols): Sort the psymtabs by
their low addresses first, then rip through fixing high addrs.
* ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
<runene@ifi.uio.no>.
(NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.

and fixes mailed to bug-gdb, and the fixes in particular will move
into these sources as I find the time.
=> THIS VERSION IS FRAGILE! <=
This release moves the generic GNU include files, the BFD ("binary
file description") library, the
getopt routines, obstacks, and the readline library into the parent
directory of gdb. The idea is that a variety of GNU tools can share a
common copy of these things.
It depends on preliminary versions of a new "binary file
descriptor" library, a new global "include" directory,
and separate libraries for "readline" and "libiberty", which
are packaged separately from GDB. You must obtain, configure
and build these libraries manually, then configure and build gdb.
When building gdb's for multiple platforms, you must manually
rebuild the libraries separately for each platform. Yes, of
course, we are working on this! FIXME!
These generic files are packaged separately from GDB. You must obtain
them separately from GDB, and unpack them into the same directory, so
that the directories:
Configure and build the libraries for your host system by:
bfd gdb include libiberty readline texinfo
cd ../bfd
./configure HOSTNAME
make
are all in the same directory. There should also be a "configure"
script (and its parameters, in "configure.in" and "Makefile.in"),
in the same place.
cd ../libiberty
./configure HOSTNAME
make
Once you have this stuff unpacked, you can cd to the directory in which
you unpacked them, and type:
./configure HOSTNAME
make
and all the libraries, as well as GDB will be configured and built.
When building gdb's for multiple platforms, you must manually
rebuild the libraries separately for each platform. FIXME FIXME no more!
MENTION VPATH.

Then you can cd ../gdb-whatever, and config and build gdb.

A summary of features new since gdb-3.5 is in the file `WHATS.NEW'.
The best way to build GDB, in my opinion, is in a subdirectory. I use
a naming convention "=XXX" where XXX is the machine type I'm building
for. Nothing depends on this, it's just how I remember which
subdirectories are what. So, once you have the BFD library built for
that machine, you can do:
The best way to build GDB (and the supporting libraries and include
files), in my opinion, is in subdirectories. The configure script
does this automatically if you specify more than one HOSTNAME; you can
force it, even for one host only, by using configure's "+forcesubdirs"
option (which you can abbreviate to +f). configure will create two
directory levels, Host-machine and Target-machine. "machine"
depends on your configuration options; the two directory levels
reflect the fact that GDB can be configured for cross-debugging
(described further below).
cd gdb-x.yy (the directory where this README is)
mkdir =XXX (e.g. mkdir =vax)
cd =XXX
../config.gdb machine
For example, you can do
cd .. (the directory *above* where this README is)
configure +f mymachine
cd Host-mymachine/Target-mymachine
make
Machine is like "vax" or "sun4". For more information type `../config.gdb'.
Machine is like "vax" or "sun4". For more information type
`./configure'. For a list of host machines, see the "xconfig"
directory; for a list of targets, see the "tconfig" directory.
Once you have done that, just `make' will do everything, producing an
executable `gdb' in this directory.
executable `gdb' in this directory. You can install it anywhere; it has
no hardwired paths in it. However, you should make sure that the shell
on your path (named by the SHELL environment variable) is publicly
readable; various systems refuse to let GDB debug child programs which
are not readable, and GDB uses the shell to start your program.
You can also build gdb binaries in a completely different directory from its
sources, by specifying "srcdir=YYY" to config.gdb, giving it an absolute
or relative path to the source directory.
sources, by specifying "-destdir=YYY" to ./configure, giving it an absolute
or relative path to the installation directory.
GDB can be used as a cross-debugger, running on a machine of one type
while debugging a program running on a machine of another type. You
configure it this way by specifying `config.gdb host target' where host
is where GDB runs, and target is where your program runs.

make gdb.dvi
to make the TeX device-independent output file, or
make gdb.info
to make the "info" version for online browsing. The former assumes
you have a running TeX on your system; the latter, a running makeinfo.
The source for the GDB manual is in the doc/gdb.texinfo file (and a
few other files it includes) provided with this distribution. The
Makefile attempts to use a texinfo.tex from a "texinfo" directory
parallel to the GDB directory (../texinfo/texinfo.tex, from the
directory where this README is). For details see the texinfo manual
(distributed with emacs and as a printed manual).
About languages other than C...
C++ support has been integrated into gdb. GDB should work with FORTRAN
programs. (If you have problem, please send a bug report; note that you
programs. (If you have problems, please send a bug report; you
may have to refer to some FORTRAN variables with a trailing
underscore). I am not aware of anyone who is working on getting it
underscore). I am not aware of anyone who is working on getting gdb
to use the syntax of any language other than C or C++. Pascal programs
which use sets, subranges, file variables, or nested functions will not
currently work.
