I have 64 bit solaris - sparc and opteron systems. Under /usr/local/lib , I can see libiconv.so for both systems. The file command on libiconv.so gives following output:-
ELF 32-bit LSB dynamic lib 80386 Version 1, dynamically linked, not stripped, no debugging information available
How do I build 64 bit libiconv w/o disturbing existing 32 bit on both sparc and opteron systems? Reason being, I am not aware of existing version of libiconv.
This libiconv.so is not part of the OS being in the non standard /usr/local/lib. Should you want to build yourself or install from elsewhere a 64 bit version of this library, you would install it in /usr/local/lib/amd64 or /usr/local/lib/64.
However, this is probably useless in the first place as Solaris already includes the iconv library function in its standard C library so Gnu libiconv is basically redundant and unnecessary here.
