[Qt-interest] Link error when compile the application in Solaris

[lvbing lvbing]

platform:Solaris 10 + Qt4.5.3

The link error information is:
std::ostream & std::ostream::operator<<(short)
/users/ems/pcs9700/deployment/bin/plat/libsmcfgapi.so
ld:Fatal error:Command failed for
target  /users/ems/pcs9700/deployment/bin/plat/update_schema'

I compile those code in WinXp or Win7 or Linux all are OK! but just in
Solaris,failed!

and If I add this to my pro:
LIBS += -lsmcfgapi
it can be compiled success!
 My puzzle is In my code I did not call any API from smcfgapi，just some
other library may call the smcfgapi.so.
so,Why just the only Solaris,need to add the smcfgapi, but other operater
not need!!!

thanks!
