[SOLVED] Kali Linux on Raspberry 5: Missing gdb
lazarus / 32-Linux

I have installed Lazarus on Kali Linux on Raspberry 5 from https://sou
rceforge.net/projects/lazarus/files/Lazarus%20Linux%20arm64%20DEB/Laza
rus%204.4/
It complained about some library (libgtk-x11-2.0.so) missing, with
some fiddling (most likely sudo apt-get update && sudo apt-get install
--reinstall libgtk2.0-0 and some more), I got it installed.

But now I get The debugger "/usr/bin/gdb" does not exist and is not
executable. I also get this on the start-up screen.
I found a 1,7 kB file named gdb in /usr/share/bash-completions/, but
Lazarus says it is not executable.
What else can I do to run the debugger?

Do you need to install gdb as a separate package? Even assuming that
the compilers etc. from (what Debian calls) build-essential are
preinstalled I'm used to having to add it manually at the same time as
I install subversion etc.

I'm currently- and very cautiously- working through some server
rebuilds, and one of the things I'm doing is comparing what's on
Debian 13 with or without a desktop environment. If I tell it to
install a desktop environment (specifically, KDE) it includes both
build-essential and gdb, if I don't then I have to install the two
individually plus typically gdbserver.

Indeed, I have always thought that GDB is sth. that comes with
Lazarus, maybe it is true for Windows.
sudo apt-get install gdb and now it works... almost, because it keeps
stopping in a timer where there is no breakpoint.

EDIT: I deleted .lps, lib and backup and now it seems fine.

You did not install build-essential?
Sudo apt install build-essential (which includes gdb and way more
essential development support)

Anyway: the gtk2 dependency is different and keeps a recurring issue.
See several other subjects.

Then again, I would expect a pen test distro to have a debugger
present.

Thanks, I added some info in https://wiki.freepascal.org/Lazarus_on_Ra
spberry_Pi#Installing_on_Kali_Linux_on_Raspberry_Pi_5 .
It is not complete, but I hope it is sufficient.

GDB is installed by build-essential, together with a.o. the GNU
compiler chain and all -dev headers.
Strange it isn't in Kali by default. It used to be.(I checked)

I wonder how to put this diplomatically?

Code: Text  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i $ apt-file
search `which gdb` 2> /dev/null | grep ^gdb:gdb: /usr/bin/gdbgdb:
/usr/bin/gdb-add-indexgdb: /usr/bin/gdbtui 
So: it's in the gdb package, not in build-essential, and that's been
the situation for at least ten years.

I am used that the DEB files either install the dependencies
automatically or ask the user if (s)he wants to.
Could not the Lazarus*.deb do the same? Check if gdb is present and to
install it if it is missing?

install build-essential which will install the gnu toolchain and
includes gdb.
It is also one of the documented dependencies.
