Build error: cannot find -lc

[Thiago Holanda <tholanda@gmail.com>]

Hello all,

I am using the Ubuntu 11.04 and I downloaded and installed the gnat-
gpl-2011-x86_64-pc-linux-gnu-bin.tar.gz.

My code (uglyform.adb) in GPS is:

with Ada.Text_IO;
use Ada.Text_IO;
procedure UglyForm is begin
   Put   ("Good form ");
   Put("can aid in ");
   Put("understanding a program,");
   New_Line;
   Put("and bad form ");
   Put("can make a program ");
   Put("unreadable.");
   New_Line;
end UglyForm;

I can compile it:

gnatmake -ws -c -u -P/home/thiago/Documents/works/Ada/default.gpr -
XBUILD=Debug uglyform.adb
gcc -c -g -g -gnato -fstack-check -gnatVa -I- -gnatA /home/thiago/
Documents/works/Ada/src/uglyform.adb

[2011-09-07 20:59:41] process terminated successfully (elapsed time:
00.15s)

But, when I build it, one error happens:

gnatmake -d -P/home/thiago/Documents/works/Ada/default.gpr -
XBUILD=Debug uglyform.adb

gnatlink /home/thiago/Documents/works/Ada/bin/uglyform.ali -g -g -o /
home/thiago/Documents/works/Ada/exec/uglyform
/usr/gnat/libexec/gcc/x86_64-pc-linux-gnu/4.5.3/ld: cannot find -lc
collect2: ld returned 1 exit status
gnatlink: error when calling /usr/gnat/bin/gcc
gnatmake: *** link failed.

[2011-09-07 21:03:36] process exited with status 4 (elapsed time:
00.15s)

Thank you for any help.

Regards,

Thiago
