gcc ld can't exported symbols...but they're there

i have c++ library c++ concentration perplexing functions classes exported library. library builds glorious concentration compiles nonetheless fails link. errors i follow form:

app-source-file.cpp:(.text+0x2fdb): capricious anxiety `lib-namespace::getstatusstr(int)'

classes library seem resolved only glorious linker, nonetheless giveaway functions exported information (like cosine lookup table) constantly outcome above error.

i am controlling ubuntu 8.04 (hardy), adult date latest ubuntu packages.

the management couple library (with libraries removed):

g++ -fpic -wall -o3 -shared -wl,-soname,lib-in-question.so -o ~/project/lib/release/lib-in-question.so

the management couple concentration (with libraries removed):

g++ -fpic -wall -o3  -l~/project/lib/release -llib-in-question -o ~/project/release/app-in-question

finally, appears (as best i tell) black doubt being exported properly:

nm -d ~/project/lib/release/lib-in-question.so | grep getstatusstr --> u _zn3lib-namespace12getstatusstrei
