Building GDB

Building GDB

[Levente]

Hi all,



I'm putting together a toolchain for AVR micro-controllers, and want to 
build GDB without binutils. I checked out the source, and when I'm on 
the binutils-2_42 tag, the build fails with this:

CXX    tui/tui-command.o
In file included from ../../gdb/tui/tui-data.h:28,
                   from ../../gdb/tui/tui-command.c:24:
../../gdb/../gdbsupport/gdb-checked-static-cast.h: In instantiation of 
‘T gdb::checked_static_cast(V*) [with T = tui_cmd_window*; V = 
tui_win_info]’:
../../gdb/tui/tui-command.c:65:15:   required from here
../../gdb/../gdbsupport/gdb-checked-static-cast.h:63:14: error: cannot 
convert from pointer to base class ‘tui_win_info’ to pointer to derived 
class ‘tui_cmd_window’ because the base is virtual
     63 |   T result = static_cast<T> (v);
        |              ^~~~~~~~~~~~~~~~~~
make[2]: *** [Makefile:1930: tui/tui-command.o] Error 1


So I decided to build gdb and binutils separately from different 
commits. I can disable GDB by specifying --without-gdb.

The question is, how can I build GDB without binutils?

So here is what I want to do:

check out binutils-2_42
configure/build/install binutils
clean the repo
chec out gdb-14.1-release
configure/build/install gcc

How can I do this?



Thanks,
Lev

I did this as follows (through experimentation)

git checkout gdb-14.1-release
mkdir build
cd build
../configure --disable-binutils --disable-gas --disable-ld --disable-gprof
--disable-gprofng --prefix=/your/path/here

This will build the bits necessary for building gdb, then build gcore, gdb,
gdb-add-index and gdbserver.

There might be a better - that is, official - way of doing this.

Note that this isn't the only top-level component built for GDB only. 
 From an email in January, the full list of components to be disabled 
is: --disable-gdb --disable-gdbserver --disable-libbacktrace 
--disable-libdecnumber --disable-readline --disable-sim

There was some chat of adding a single option to disable all of GDB and 
all of binutils, but I don't think that was ever implemented... or if it 
was, it escaped my notice.

Building gdb

When I build gdb 6.3, I get the output
  ada-lex.c missing and flex not available.

Is there a way to build if flex is not available?

How crippled is your host system then if you do not have flex?

I think someone forgot to commit ada-lex.c to the CVS repository.

It's supposed to be generated in snapshots, not in CVS.  It should
probably be added to either YYFILES or DISTSTUFF.
