Hi Saleem,

In the EPICS Makefile, you have to set the library name by setting the

base name *without the '-l' option for the linker*.

    PCI7434_LIBS += pci_dask

You should also specify the location:

    pci_dask_DIR = /wherever/this/library/is/located

Chapter 4 of the Application Developer's Guide has all the details.

HTH,

Dear Dirk Zimoch,

I am writing device support for a digital output card from Adlink,

PCI-7434. Adlink ships a shared library file "libpci_dask.so" that

needs to be linked with every code we write for these DO cards. Here

is the normal gcc command line which successfully compiles a code

written for PCI-7434.

gcc -o 7434test -lpci_dask 7434test.o conio.o

I have written device support routines for this card and now I am

trying to include it in IOC. However, It gives the following error,

every time I type make.
