Hi All,
I have just installed gcc 4.1.1 and when i try to execute g++, i am getting this error:
sh-3.2# g++
/usr/lib/pa20_64/dld.sl: Unable to find library 'libiconv.sl.4'.
Killed
I have installed libiconv also.
I have the following version of gcc:
sh-3.2# gcc --v
Using built-in specs.

There is an HP-UX forum, which might work
better for this question than this Linux
forum.

From what? How?

From what? How?

Are you using the "g++" which you installed?

If you have a working gcc, you might try
building a complete GCC kit from source.
Version 4.3.1 seems to be current. 4.3.0
worked well for me on a similar system
(after getting all the (many) prerequisites
lined up).

Welcome to the ITRC Forums!

(Nitpick: this specific part of the forums is for Linux, but the question is about HP-UX. I'll submit a request to move the thread to the appropriate forum section.)

Where did you get your gcc from?
Did you know that HP offers a pre-packaged GCC for the currently-supported versions of HP-UX?
See:
http://www.hp.com/go/gcc

Maybe your libiconv library is not located where g++ expects to find it? Or maybe the g++ requires a _64-bit_ version of the library?

Run "ldd $(which g++)" to see all the libraries required by g++.
Run "chatr $(which g++)" to find out where the g++ binary expects to find these libraries.

Show us the output of those commands, so that we might be able to help you better.

If you have g++ and gcc, you probably have binutils, run ldd on g++:
"/usr/local/bin/ldd /usr/local/bin/g++"

This tell you what version g++ wants of libiconv. In your example it seems g++ has told the dynamic linker dld that it wants libiconv.sl.4

If you have it installed but maybe in some path dld cant find, (example /usr/local/lib) then try:
LD_LIBRARY_PATH=/usr/local/lib g++

Also try symlinking your libiconv file to "libiconv.sl.4" in some temporary dir and point LD_LIBRARY_PATH to it like above.
