while compiling with static library (okFrontPanel.a) in Linux Environment (FC2)
I met this linking error message below.
I don’t know why g++ cannot find sysbol infomations in the static library.
(I renamed okFrontPanel.a --> libokFrontPanel.a)

what should I do…? please help me… :confused:
Thanks for reading.

You also need -lusb.

The Linux version of the FrontPanel API depends on ‘libusb’. Most distributions have libusb 0.1.8 installed by default. That should do.

Note, some distributions have a bug with libusb that will also manifest with the FrontPanel API. Namely, Fedora Core 3, FC4, and SuSE 9.2 all have problems with libusb.

Thanks for your help.
some linking error messages concerning the libusb library has gone.
but still remain some messages about library 'okFrontPanel.a ’
what’s wrong…??
