Глюк компилятора.  Происходит примерно вот что (в упрощенном виде).

$ g++ -ldl -shared -Wl,-hlibxplc-0.3.so -Wl,--version-script=config/exports.map xplc/category.o xplc/catiter.o xplc/catmgr.o xplc/loader.o xplc/moduleloader.o xplc/modulemgr.o xplc/monikers.o xplc/new.o xplc/servmgr.o xplc/statichandler.o libxplc-cxx.so -o libxplc.so -Wl,-z,defs
xplc/loader.o: In function `loaderOpen(char const*, void**)':loader.cpp:(.text+0x1a): undefined reference to `dlerror'
:loader.cpp:(.text+0x2d): undefined reference to `dlopen'
:loader.cpp:(.text+0x45): undefined reference to `dlerror'

$

То есть я даю ему -ldl, но он в упор не видит dlopen.

Теперь я переставляю -ldl с первого места на последнее:

$ g++ -shared -Wl,-hlibxplc-0.3.so -Wl,--version-script=config/exports.map xplc/category.o xplc/catiter.o xplc/catmgr.o xplc/loader.o xplc/moduleloader.o xplc/modulemgr.o xplc/monikers.o xplc/new.o xplc/servmgr.o xplc/statichandler.o libxplc-cxx.so -o libxplc.so -Wl,-z,defs -ldl
$

Получилось!
Документирован ли порядок аргументов у gcc?
