[Spice-devel] Fwd: libcacard: forward declaration of VReader

[Alex Roithman]

Hmmm...
If i use vreader_get_name(VReader*) method,
then i have :

CMakeFiles/qt4-virt-manager.dir/src/vm_viewer/qspice_widgets/qspicesmartcardmanager.cpp.o:
In function `QSpiceSmartcardManager::spiceSmartcardManager_get_readers()':
qspicesmartcardmanager.cpp:(.text+0x390): undefined reference to
`vreader_get_name(VReaderStruct*)'
collect2: error: ld returned 1 exit status

while libcacard and includes detected:
