How to repeat:

# tar xvf mysql-connector-c++-1.0.5.tar

# cd mysql-connector-c++-1.0.5

Suggested fix:

Looks to be a missmatch of 32bit and 64bit files.

Hi Patrick and thanks for your report.

I've asked our build master to take a look.

You could try the following:

 1) Remove the CMakeCache.txt file if any

 2) Set in your environment (assuming you use SunStudio

ASFLAGS=-m64
CC=cc
CFLAGS=-xO2 -xtarget=generic -m64 -mt -xstrconst
CPPFLAGS=-D_POSIX_PTHREAD_SEMANTICS
CXX=CC
CXXFLAGS=-xO2 -xtarget=generic -m64 -mt
LDFLAGS=-m64
export ASFLAGS CC CFLAGS CPPFLAGS CXX CXXFLAGS LDFLAGS

  You can always find the environment used to produce the packages provided
  by Sun at the end of the README file in the binary packages, in this case inside
  mysql-connector-c++-1.1.0-solaris10-x86-64bit.tar.gz

 3) Rerun the build

 4) If it still fails the same way, please rerun your build with "make VERBOSE=1" and compress and attach the complete log to this bug report

Hi,
I'm sorry to say we have no servers that can are running OpenSolaris anymore.

It was 100% reporoducible with the information provided in the bug.  Fresh install of OpenSolaris, with MySql server 5.1.39 and C++/Connector 1.0.5.  

BR Patrick

Patrick, I can't go on verifying this and not knowing if your cache files were tainted the way Kent described. The fact that, maybe, there was bad CMakeCache.txt file left over from our builds does not constitute a bug per-se as removing that file before (re)building is a known request.

Will consult Kent once more though.
