GDB and Insight query

GDB and Insight query

Hi,
      I am trying to use "Insight" which is a GUI to native gdb. I did
the following steps:
1. ./configure --prefix [dir]
2. make 
3. make install

The software seems to have been installed, but when I run [dir]/bin/gdb,
I get the following error:
----------------- Log -----------------
./gdb
ld.so.1: ./gdb: fatal: libncurses.so.5: open failed: No such file or
directory
Killed
---------------------------------------

I am not sure why I got this error and I need some guidance to get
around this. Looks like the "gdb" delivered as a part of Insight is
trying to use ncurses, whereas it should not.

The "Insight" guys asked me to get in touch with you. Please read the
following mail trail for details.

Any help in this regards is appreciated.

Thanks,
- Manish M

Insight does not use ncurses. I would try building *just* gdb (no
insight) 
from 5.2 (--disable-gdbtk option). If it fails with the same error (and 
I'm sure it will), contact gdb@sources.redhat.com, the GDB mailing
lists. 
They should be able to help you.

Hi,
      I am trying to use Insight 5.2 on a SUN machine. I did the
following three steps:

1. ./configure --prefix [dir]
2. make 
3. make install

After the above three steps, the software seems to have been installed
in the [dir] I wanted, but when I try to execute it by doing a ./gdb
from [dir]/bin, it gives me the following error and exits. Any ideas!
----------------- Log -----------------
./gdb
ld.so.1: ./gdb: fatal: libncurses.so.5: open failed: No such file or
directory
Killed
---------------------------------------

Thanks,
- Manish M

Instead of ./configure do the following

./configure --prefix=[dir]
replacing [dir] with the directory that you want Insight installed into.

You can then run Insight by typing ./gdb in [dir]/bin.  BTW I don't know
if
it's clear on your text editor (it's not on mine) but there are 2 dashes
in
front of "prefix" in the configure statement.

Have fun,

Hi There,

I am trying to use Insight. I have a SUN machine.

I have successfully downloaded the tar.gz file and have run the
./configure command. I have also run the "make" command and everything
seems to have built properly.

Now, how do I invoke Insight. The README file states that I have to
install the tools by doing a "make install". However, when I invoke the
command it tries to install the tools in /usr/local/lib perhaps and I
dont have write priviledges to that directory.

How do I install the tools in some other personal directory? After
installing the tools, how do I invoke Insight?

Thanks,
- Manish M

Some thoughts: What did gdb link against? Can you do "rm gdb; make" in 
the gdb build directory and send the result?

Is LD_LIBRARY_PATH (or equivalent under Solaris) set properly?

Thanks. In this I see:

  checking for ncurses.h... yes
  checking for tgetent in -lncurses... yes

and

gcc -g -O2  -I/usr/include/v9      -o gdb \

So you must have ncurses somewhere.

Hmmm. Google search revealed this:
http://groups.google.com/groups?q=ncurses+gdb+solaris&hl=en&lr=&ie=UTF-8&selm=200006282023.NAA16273%40ruby.twinsun.com&rnum=1

Does libncurses exist in any of these directories? What does "gcc -v" say 
(out of curiosity).

I'd hazard a guess that it is LD_LIBRARY_PATH. :-)

Somewhere, GDB found libncurses.so.5 to link against. We need to find the 
library and get its path added to LD_LIBRARY_PATH (so that it can be 
found by the dynamic linker/loader can find it).
