Solaris

Hi,

I have to build an application on solaris 9 which is supposed to run on solaris 10 computers.

I heard that solaris 9 builds should run on solaris 10 without any troubles. However, there is some trouble.

Calling ldd on the programm reveals that "libgcc_s.so.1" and "libstdc++.so.6" are not found. Ok, I could add the rpath to the linker line, but to which directory? On my solaris 10 test system, there are different versions of these libraries in different (not very common) directories. Where are those guys located by default? Can I rely on that? What other options do I have?

A more basic question is, why does ldd give very different results on solaris9 and solaris10, when called on the same file?

Thanks for your help?
Mike

AFAIK, gcc libraries aren't standard on Solaris 9. Where are these libraries located on your Solaris 9 machine ?
Pick the version expected by your binary.
Because ldd recursively resolve dependencies. To get what the binary requires, you can use that command:

Code:

elfdump -d command | grep NEEDED

The elfdump shows (on both platforms)
elfdump -d *** | grep NEEDED
[0] NEEDED 0x3eb76 libsocket.so.1
[1] NEEDED 0x3eb8e libnsl.so.1
[2] NEEDED 0x3ebaa libpthread.so.1
[3] NEEDED 0x3ebc3 libgcc_s.so.1

libgcc_s.so.1 location is /usr/local/lib/sparcv9/libgcc_s.so.1

From the somewhat bogus directory, I would suspect these libraries to come from sunfreeware.com. You might want to pick the missing libs there for Solaris 10 too.

yes, thanks for your help.
