An install question and a bug

An install question and a bug

[Salman Khilji]

Mandrake Linux 8.1, gcc 2.96, gdb 5.1.1

When I configure the source code for gdb 5.1.1, it says after a while . . .

...
...
checking for tgetent in -lterminfo... no
configure: error: Could not find a term library
Configure in /home/salman/softdev/gdb/gdb-5.1.1/gdb failed, exiting.

What is term library?  Where do I install this from?

Here is a bug that I just submitted through the bug reporting database on 
the gdb homepage.  I searched for it in the archives and someone asked the 
exact same question but didn't receive a reply.  Anyone has a solution or 
patch to this?:

Cannot look at global variables inside a C++ namespace
======================================================
reproducable on 5.0 and 5.1 of gdb

Assuming the code:

#include <iostream>
using namespace std;

namespace FOO{
  float fSomeVar = 67.8;
}

namespace BAR{
  float fSomeVar = 27.2;
}

float fSomeVar = 23.0;

int main()
{
   FOO::fSomeVar = 100.0;
   BAR::fSomeVar = 200.0;
   fSomeVar = 300.0;

   cout << FOO::fSomeVar << endl;
   cout << BAR::fSomeVar << endl;
   cout << fSomeVar << endl;

   return 0;
}




The gdb output as is follows---Please note that I have tried the string with 
and without single-quotes.  GDB doesn't find the symbol without the 
quotes---with the quotes it is giving me a junk value:

Term, termcap, curses, ncurses, ... are all libraries that can be used 
when controlling a text based display (a tty).  Things like, terminal 
width and height, but also other things.

In the above, it appears that the configuration process can't find a 
suitable library.  There could be two reasons for this:

o 
a library is missing from your system (less likely)

o 
GDB's configuration messed up and didn't detect the library your system 
has installed (more likely)

The script gdb/configure (generated from gdb/configure.in) controls this.


You mentioned that you were using 5.1.  Was that built by you or did it come with a Mandrake distro?

If it came with a Mandrake distro I suspect the first thing to do is 
find out how that was built - 5.1 and 5.1.1 are only marginally different.

I am using 
ftp://speakeasy.rpmfind.net/linux/Mandrake-devel/cooker/SRPMS/gdb-5.1-3mdk.src.rpm

I tried it on two Mandrake 8.1 systems.  both give me the error that 
libterminfo is not found.  If I got to Mandrake's side, there is no such 
thing as libterminfo for Mandrake.  The PLD Linux distribution, however, 
does have a libterminfo package.  I am too scared to install it.  What would 
you recommend??

All I do is just type ./configre --with-mmap

No other options.

Here is a hint that I got from someone else about this issue.  Still no luck 
:-(

urpmi libtermcap2-devel

You are problabyl looking for the NCurses development package.  I don't
know what Mandrake calls it.
