Re: how to fix crt1.o: No such file or directory (link error for gnat)? after installing gnat 2012 on linux

["Nasser M. Abbasi" <nma@12000.org>]

solved it!

here it is, in case someone else hits this problem:

>export LIBRARY_PATH=/usr/lib/i386-linux-gnu/

>gnatmake -gnat2012 t44.adb
gcc -c -gnat2012 t44.adb
gnatbind -x t44.ali
gnatlink t44.ali

I do not know why it happens, but the above will fix it.
