Asking regarding 64-bit porting

[yck]

Hi all,
I face a problem when compiling C++ code in 64-bit. Below is the error message:
ld: Can't find library for -lnsl_s
I figure out that only /usr/lib have this library file but /usr/lib/pa20_64 didn't have this file. What should I do? Is that exists 64-bit version of libnsl_s.a library? Or got any alternative to solve this problem?

Thanks.

Youre right, there is no 64 bit version of the library libnsl_s. So you have 2 options.

1. compile your program as 32bit only, or;

2. Find the symbol/code in libnsl_s that your are trying to reference and search the other 64bit libraries to see if you can find a 64bit version of it (using the nm command), and if you find it you can link it in from the 64bit lib instead, now you can compile 64bit.
