OS - HP-UX 10.2
I just installed patches for aC++ runtime (aCC A.01.3)

Usually this means that your C source code or one (or more) of object files you try to link into executable references this function as code (jump to it and execute). There's no its body (code) in all object files you give for linking, and linker can't find it in default library.
Please check if you missed any object file(s) to add to link list (or remove unneeded), check your source code for errors.

Just as was said, but...

vsnprintf() is a part of standart library, so I don't think that any object is missing. The change was made (probarly) by this patch. Check the description of vsnprintf() in manuals if this dos not requre any special linking now.

Hi,

Did you check if there are any special instructions with these patches?
Can you provide me with the names of the patches?

Hi,
just found an interesting document:

###############
vsnprintf does not have a specific header file in HP-UX 10.20.
vsnprintf support begins at HP-UX 10.30. This information is documented
in the 10.30 release notes.

Although vsnprintf exists in the 10.20 version of libc, it is not
documented, and not present in header files.
#################

So i guess your program might be custom....
which patch did you installed ?

have you a copy of your libc BEFORE patching, to check with the commands suggested by the others ?

May be you should think about a replacement for the libc... i will never suggest to remove a patch.
