[Apcupsd-users] Link problem on Solaris 11.3

[Phil Stracchino]

I'm bringing up a new server, a SunFire X4540 on which I've installed
Solaris 11.3, and I'm attempting to install apcupsd 3.14.4, compiling
using gcc-4.9.4. Very simple basic configuration with no frills:

./configure --prefix=/usr --sysconfdir=/etc --with-log-dir=/var/log

Everything goes fine until link time, when I get an unresolved symbol:

LD src/apcupsd
Undefined first referenced
symbol in file
_Unwind_GetIPInfo
/usr/gcc/4.9/lib/gcc/i386-pc-solaris2.11/4.9.4/../../../libsupc++.a(eh_personality.o)
ld: fatal: symbol referencing errors
collect2: error: ld returned 1 exit status


Does anyone have any insights on resolving this problem?

My Google Fu came up with:

_Unwind_GetIPInfo is defined in libgcc_s.so - is that file present in
the same directory as libstdc++.so?

If you add -v to the compilation command it will show you the
directories gcc searches, is libgcc_s.so in any of those directories?

I will definitely check for that and give it a try. I hunted for a
reference to where it was defined but couldn't find one.

Turns out that libgcc_s.so was present everywhere it should be, but
adding -lgcc_s did not resolve the issue. (Or the symbol.)

I tried compiling with Oracle Developer Studio instead of gcc to see if
I could avoid the link problem. Turns out apcupsd won't compile at all
using Sun^WOracle CC.

Phil,

Do you have LD_LIBRARY_PATH defined to put perhaps an older or different
library ahead of the correct library?

It looks to me like maybe you have multiple compiler versions on that
machine and the library path search order is fubared.

Hmm .... now that you mention it, it is *possible* the linker is
picking up the system's libgcc_s instead of the C compiler's. It
*SHOULDN'T* be doing so, but...

I gave up fighting the link problem a few days ago and installed
OpenCSW's apcupsd package, and that sees to be working fine. The link
problem hasn't occurred with anything else I've built.
