"Missing" libraries when running the IOC #13

Closed dungducphan closed 7 months ago

dungducphan commented 7 months ago

After building successfully, I tried to run the IOC (ADSpinnaker/iocs/spinnakerIOC/bin/linux-x86_64/spinnakerApp) but encounter the error of missing libGenApi_gcc11_v3_0.so. This lib file is in spinnakerSupport/os/linux-x86_64 but somehow there is no EPICS variable pointing to it. I ended up making a symlink from spinnakerSupport/os/linux-x86_64 to /usr/lib/ to run the IOC.

I think I missed something in the installation/configuration. What EPICS variable should point to the support libraries directory?

Thank you!

What version of Linux are you running and what version of ADSpinnaker?

dungducphan commented 7 months ago

I'm using Ubuntu 22.04 LTS. ADSpinnaker tag version R3-4 (https://github.com/areaDetector/ADSpinnaker/releases/tag/R3-4).

Here is how it is supposed to work, and it does work fine for me. I am testing R3-4 on CentOS 9 Stream. I have also tested on Ubuntu 22 and it works fine there too.

First do a clean install:

[epics@countach-c9 ADSpinnaker]$ pwd
/corvette/home/epics/devel/areaDetector/ADSpinnaker
[epics@countach-c9 ADSpinnaker]$ make -sj clean
[epics@countach-c9 ADSpinnaker]$ make -sj
/usr/bin/ld: /corvette/home/epics/devel/areaDetector-3-13/ADSupport/lib/linux-x86_64/libjp2.a(jas_stream.o): in function `jas_stream_tmpfile':
/home/epics/devel/areaDetector-3-12-1/ADSupport/supportApp/GraphicsMagickSrc/jp2/src/libjasper/O.linux-x86_64/../../../../../../supportApp/GraphicsMagickSrc/jp2/src/libjasper/base/jas_stream.c:368: warning: the use of `tmpnam' is dangerous, better use `mkstemp'

Next make sure LD_LIBRARY_PATH is not set to help find any libraries:

[epics@countach-c9 ADSpinnaker]$ echo $LD_LIBRARY_PATH

Now look in ADSpinnaker/lib/linux-x86_64 to make sure that the libraries from the Spinnaker SDK were correctly installed there from spinnakerSupport:

[epics@countach-c9 ADSpinnaker]$ ls -l lib/linux-x86_64/
total 134744

-r--r--r-- 1 epics domain users 42121872 Feb  2 08:35 libSpinnaker.so.3
-r--r--r-- 1 epics domain users 42121872 Feb  2 08:35 libSpinnaker.so.3.1.0.79
-r--r--r-- 1 epics domain users  2071616 Feb  2 08:35 libXmlParser_gcc11_v3_0.so

Note that libGenApi_gcc11_v3_0.so is correctly installed there.

Now run ldd on spinnakerApp to make sure it finds libGenApi_gcc11_v3_0.so correctly, which it does.

        libXau.so.6 => /lib64/libXau.so.6 (0x00007f9984a3f000)

Now run the IOC:

[epics@countach-c9 ADSpinnaker]$ cd iocs/spinnakerIOC/iocBoot/iocSpinnaker/

dbLoadDatabase("/corvette/home/epics/devel/areaDetector-3-13/ADSpinnaker/iocs/spinnakerIOC/dbd/spinnakerApp.dbd")
spinnakerApp_registerRecordDeviceDriver(pdbbase)

The IOC works fine, it finds libGCBase_gcc11_v3_0.so and all of the other libraries.

Hi Mark, thank you for digging into this problem.

I have the IOC working find now. What I did:

The build completed without problem. ldd iocs/spinnakerIOC/bin/linux-x86_64/spinnakerApp shows all the Spinnaker libraries. The IOC runs fine and allows me to control my FLIR cameras.

MarkRivers commented 7 months ago

@dungducphan good news.

One thing you might want to consider is rather than downloading the tarball, to use git clone instead:

git clone https://github.com/areaDetector/ADSpinnaker
cd ADSpinnaker
git checkout R3-4

That way if there are future bug fixes on the master branch you can simply do the following:

cd ADSpinnaker
git checkout master
git pull

Or if there is a new R3-5 release

cd ADSpinnaker
git pull
git checkout R3-5
