Hello i'm trying to compile for LabView71 C source program (using Code external nodes) that reads data from PCIe device.
when i run "./lvmkmf pcie" - it generates Makefile and it`s ok, but after i run "make" the following error i see:
# make
gcc -shared -o pcie.tmp \
/usr/local/lv71/cintools/cin.o pcie.o /usr/local/lv71/cintools/libcin.a
/usr/local/lv71/cintools/lvsbutil -c pcie -t CIN -d "`pwd`"
/usr/local/lv71/cintools/pcie.tmp: undefined symbol: CINRun
/usr/local/lv71/cintools/lvsbutil: error building resource file: 1
make: *** [pcie.lsb] Error 2
------------------------------------------
Is there a way how to solve this problem? please help, my program source code is:
