hi Everyone!!!

I am in the midst of porting a C app to 64 bit on Solaris8. The application uses the 64 bit Oracle 8.1.7.

I am just pasting the line passed to the linker. We are compiling in 64 bit mode on solaris 8

An nm on the libaio in /usr/lib/sparcv9/libaio.so confirms that the the symbols are indeed defined in libaio. So ideally the linker should be able to resolve these symbols.
Linking additionally with boht librt and libaio solves the problem but librt implements the POSIX specifications for Asynchronous I/O where as libaio is the SUNW sun's own specification.

So the question is
1.Whether Oracle 8i (64 bit)indeed needs linking with both librt and libaio. (the 32 bit version of Oracle 8i is linking fine just with libaio)
2. If not, whats missing??

Thanks a ton in advance for all the replies...
