The error "seemingly" has been solved, but new problems occur.

I repeted the same make process I did yesterday in my PC with CentOS 7 instead of crio, the result didn't change. 
Thus I thought maybe the "Makefile" in the top directory doesn't contain informations about the subdirectory "lvPortDriverApp". 
So I want to "make" in this subdirectory firstly. I put those labview headers to ./lvPortDriverApp/src, 
commented out "CROSS_COMPILER_TARGET_ARCHS += win32-x86-mingw" in ./configure/CONFIG_SITE,
 "make" in /lvPortDriverApp and top directory sequentially, put liblvPortDriver.so liblvtest.so to /usr/lib and "ldconfig".
 After these steps I finnally built the lvPortDriver without "errors".

Then I installed the VIP file(Note that I use the inital version since my LabVIEW is 2015 32-bit),
and changed Initdone VI's library name from ".dll" to ".so". When I deploy and run the LabVIEW program on crio,
the connection between PC and crio would break. It seem was caused by "lvInitialized" function.
I just deleted other Call library function nodes except "callmain" since what I only want to do is starting IOC.
However in this case it neither produced error nor started the IOC successfully (I can't "caget" the PVs).

If the liblvtest.so file exists, why the LabVIEW program can't call it in right way? Is the .so file wrong?
When I use the "callmain" function, whether the program can stop?  Will it run the "iocsh" all the time?

Thank you very much!!!

lvPortDriver.dbd should be located in lvPortDriverApp/src,

and when that directory builds, it should be installed into the dbd folder

for your system that would be: /usr/local/EPICS/synapp/support/lvPortDriver-master/dbd/

perhaps somethings going wrong the build or install from lvPortDriverApp/src  (like no permission to create the directory, or a case mismatch in the filename)

Dear Dr. Baily,

 

Thank you very much for giving me these instructions about "lvPortDriver"! But I'm still unable to build it successfully. 

 

I built the EPICS base 3.14.12.7, asyn4-30, and put the LabVIEW header(my version is LabVIEW-2015 32-bit for windows) 

and the newer released version of lvPortDriver to my cRIO-9030.

Then I set the ./configure/RELEASE file like (annotations in the file are omitted ):

 

EPICS_RELEASE = R3.14.12.7

SUPPORT=/usr/local/EPICS/synapp/support

ASYN=/usr/local/EPICS/synapp/support/asyn4-30

LINUX_GPIB=NO

LABVIEW=/usr/local/EPICS/synapp/support/labview

EPICS_BASE= /usr/local/EPICS/base-3.14.12.7

 

Next I typed "make" in this configure directory, "cd ../",and "make" in the lvPortDriver directory.

But errors occur:

 

make[3]: Entering directory '/usr/local/EPICS/synapp/support/lvPortDriver-master/lvtestApp/src/O.linux-x86_64'
perl /usr/local/EPICS/base-3.14.12.7/bin/linux-x86_64/makeIncludeDbd.pl base.dbd lvPortDriver.dbd asyn.dbd lvtestInclude.dbd

make[2]: *** [install.linux-x86_64] Error 2

 

I tried to uninstall and rebuild it several times, but the result didn't changed.

What should I do to correct the error? Look forward to your guidance. 

 

Best Regards,

Zefeng Zhao
