FLIR Spinnaker SDK: Request for input

[Mark Rivers <rivers@cars.uchicago.edu>]

Folks,

I have begun work on a new ADSpinnaker driver based on the Spinnaker SDK.  The Spinnaker libraries for Windows are no problem.  However, the Linux libraries have names like:

libGenApi_gcc540_v3_0.so
libGCBase_gcc540_v3_0.so

The name implies that they were built with gcc 5.4.0.  When I try to link against these libraries on my Centos 7 system with gcc 4.8.5 I get errors like the following:

/home/epics/devel/areaDetector-3-2/ADSpinnaker/lib/linux-x86_64/libSpinnaker.so: undefined reference to
`std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::find(char const*, unsigned long) const@GLIBCXX_3.4.21'

This means it requires GLIBCXX 3.4.21.  When I run the following command "strings" on my Centos 7 system I see that I have the following versions of GLIBCXX:

corvette:ADSpinnaker/spinnakerApp/src>strings /usr/lib/libstdc++.so.6 | grep LIBCXX
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBCXX_3.4.14
GLIBCXX_3.4.15
GLIBCXX_3.4.16
GLIBCXX_3.4.17
GLIBCXX_3.4.18
GLIBCXX_3.4.19
GLIBCXX_DEBUG_MESSAGE_LENGTH

So the most recent version I have is 3.4.19, I don't have 3.4.21.

I think it is unfortunate that their Linux Spinnaker version requires a very recent version of Linux and gcc.  I believe it will pose a problem for many of our sites that are using older versions of gcc.

Assuming it is technically possible, I would like to try to convince FLIR to release a version of the library built with an older version of gcc.  Other vendors (e.g. AVT) do this.

In order to convince them I would like to get some input from sites that are currently using Point Grey/FLIR cameras or plan to do so within a year or so.

- About how many of their cameras do you current use or plan on using within the next year?
- What version of Linux, gcc, and GLIBCXX are you using on your production machines?

Thanks,
Mark

Subject: FLIR 10Gbit Ethernet camera question


Folks,



FLIR (formerly Point Grey) has introduced 10 Gbit Ethernet cameras.  They currently sell a 4096 x 3000 pixel version which can do 68 frames/s for $3,950.  They will soon start selling a 2448 x 2048 camera which can do 162 frames/s (price not announced yet).  These are very interesting cameras, since they use the Sony CMOS chips with very low read noise and global shutter.  These data rates are 775-796 MB/s, which is more than 2x faster than the same chips using a USB-3 interface.



These cameras cannot use the FlyCap2 SDK that other Point Grey cameras use.  They require their new Spinnaker SDK.  They are GeniCAM compliant, so they may also work with the aravisGigE driver.  Note that their new BlackFlyS cameras also require the Spinnaker SDK, they don't work with FlyCap2 either.



My questions:

-          Has anyone begun an areaDetector driver that uses the Spinnaker SDK?

-          Does anyone know if these 10Gbit cameras will work with the aravisGigE driver?  Any idea if aravisGigE is capable of running at the 10GBit Ethernet speeds?



Thanks,

Mark
