Ice compiling error

Hi guys!
I need some help to compile Ice on my Slackware64-14. Your third party sources was patched and compiled without any problem.
Then I checked all paths for libraries in .../Ice-3.5.0/cpp/config/Make.rules.
The result of making is here. My maker speaks Russian, translations are mine.

A path for libiconv .so, .a and .h is proper.

I rebuilt both libiconv and its dependency - gettext packages according GNU Pages recomendations. Anyway, linker couldn't find references.

All I found by Google about errors like this was recommends to no link libiconv libs at all. Is it a right way?


gcc (GCC) 4.7.1
GNU ld (Linux/GNU Binutils) 2.22.52.0.2.20120424

Hi Andrey,

Welcome to our forums!

I would also recommend to simply not link with libiconv, as it should not be needed.

Why did you link libIce with libiconv?

Best regards,
Bernard

Hi Bernard!

Thank you for your reply!
Now I understand that I understand nothing
I didn't choose libiconv ! In other words - it's not my choice.
I thought that linker looks for libiconv_open & libiconv_close references in libiconv.
Am I wrong? Maybe another lib?

Andrey.

Hi Andrey,

The error you're getting is because libIce depends on 3 symbols (iconv_open, iconv_close and iconv), and when you link an executable - here transformdb - the linking fails because the linker can't find the library with these symbols.

On most Linux distributions, these symbols are in GLIBC, and you don't need to link explicitly with any library. For example:

nm /lib/libc.so.6 | grep iconv
00017870 T iconv
000179e0 T iconv_close
000174f0 T iconv_open

With your build, all these symbols have a lib prefix (libiconv etc.). It could be that you built libIce incorrectly, by using a separate libiconv instead of the GLIBC iconv functions.

Can you rebuild libIce and post the corresponding compilation & link output?

Best regards,
Bernard

Problem solved

Hi Bernard!
Yes, you're right. I just removed libiconv, run "ldconfig", then run "make clean" and "make".
Compiling and linking was succesfull, running all of 83 tests too.
Thank you!

Sincerely,
Andrey.
