This is GDB, the GNU source-level debugger, presently running under un*x.
A summary of new features is in the file `NEWS'.
In this release, the GDB debugger sources, the generic GNU include
files, the BFD ("binary file description") library, the readline
library, and other libraries all have directories of their own
-underneath the gdb-4.9 directory. The idea is that a variety of GNU

tools can share a common copy of these things. Be aware of variation
over time--for example don't try to build gdb with a copy of bfd from
a release other than the gdb release (such as a binutils or gas

order.

To build GDB, you can just do:
- cd gdb-4.9

./configure
make
cp gdb/gdb /usr/local/bin/gdb (or wherever you want)

The simplest way to configure and build GDB is to run `configure'
from the `gdb-VERSION-NUMBER' source directory, which in this example

`configure' options
Languages other than C
=======================
-GDB provides some support for debugging C++ programs, however that support
-only works well with GNU C++, and even then only on systems that use stabs
-debugging format. In particular, cfront based compilers such as Sun's C++
-are not fully supported.
-
-GDB should work with FORTRAN programs. If you have problems, please send a
-bug report; you may have to refer to some FORTRAN variables with a trailing
-underscore.
-
-Pascal programs which use sets, subranges, file variables, or nested functions
-will not currently work.
-
-Partial Modula-2 and Chill support is now in GDB.
-
+See the GDB manual (doc/gdb.texinfo) for information on this.
Kernel debugging
=================
The correct address for reporting bugs found in gdb is
"bug-gdb@prep.ai.mit.edu". Please email all bugs, and all requests for
help with GDB, to that address. Please include the GDB version number
-(e.g. gdb-4.9), and how you configured it (e.g. "sun4" or "mach386
+(e.g. gdb-4.12), and how you configured it (e.g. "sun4" or "mach386
host, i586-intel-synopsys target"). If you include the banner that GDB
prints when it starts up, that will give us enough information.
It has been reported that the Ultrix 4.3A compiler on decstations has the
same problems.
- If you compile gdb with gcc-2.4.5, you will get many warnings,
- but these can be ignored for now. Again, this problem is Alpha-specific.
+ Under some circumstances OSF/1 shared libraries do get relocated to a
+ different address, but gdb cannot handle these relocations yet. If you
+ encounter problems while debugging executables which use shared libraries,
+ try to relink your executable with the -non_shared option when using cc
+ or with the -static option when using gcc.
+
+ * Notes for BSD/386:
+ To compile gdb-4.12 on BSD/386, you must run the configure script and
+ its subscripts with bash. Here is an easy way to do this:
+
+ bash -c 'CONFIG_SHELL=/bin/bash ./configure'
+
+ (configure will report i386-unknown-bsd). Then, compile with the
+ standard "make" command.
GDB can produce warnings about symbols that it does not understand. By
default, these warnings are disabled. You can enable them by executing
for the convenience of people that wish to get either gdb or the testsuite
separately.

+will create and populate the directory gdb-4.12/gdb/testsuite.
Running the testsuite requires the prior installation of dejagnu, which
should be available via ftp. Once dejagnu is installed, you can run
the tests in one of two ways:
- (1) cd gdb-4.9/gdb (assuming you also unpacked gdb)
+ (1) cd gdb-4.12/gdb (assuming you also unpacked gdb)
make check
or
- (2) cd gdb-4.9/gdb/testsuite
+ (2) cd gdb-4.12/gdb/testsuite
make (builds the test executables)
make site.exp (builds the site specific file)
runtest -tool gdb GDB=../gdb (or GDB=<somepath> as appropriate)
