Yes, it should.

To diagnose this further

- first verify that the file in ../common/libcommon.a is in fact
  identical to ../common/parameters_project.o:

   nm ../common/libcommon.a > junk.1
   nm ../common/parameters_project.o > junk.2
   diff junk.1 junk.2

- assuming they are, try this:

  g++ ... -o executable ../mysql_support/libMySQLsupport.a \
    ../common/libcommon.a -Wl,-y,g_Log

The expected output is something like:

../mysql_support/libMySQLsupport.a(_sqlsession.o): reference to g_Log
../common/libcommon.a(parameters_project.o): definition of g_Log

You'll probably get different output, which may provide clues.
