Vimba X and Vimba offer numerous possibilities to cross-compile source code from a PC to an ARM board. The following documents describe a tried and tested easy solution.
Vimba X on Ubuntu 20.04 Crashes in VmbStartup()
I am developing a C++ application that uses the Vimba X API to connect to a set of Alvium G5 cameras over a GigE link. This application functions properly in Windows. However, on Linux, Ubuntu 20.04 with GCC 13.1, I observe unexpected behavior during Vimba X’s initialization. I require this linux setup to eventually port to NVIDIA’s Jetson Orin Arm64 running Ubuntu 20.04 with GC 13.1.
When my program calls Vimba’s startup function, I receive the seg fault shown below. My code looks like this:
using namespace VmbCPP;
VmbCPP::VmbSystem& sys = VmbSystem::GetInstance(); // Get a reference to the VimbaSystem singleton
VmbVersionInfo_t versionInfo;
sys.QueryVersion( versionInfo );
fmt::print( "Vmb Version Major: {} Minor: {} Patch: {}\n\n",
versionInfo.major, versionInfo.minor, versionInfo.patch ); //prints 1.0.2
fmt::print("Calling startup...\n" );
VmbErrorType err = sys.Startup(); // Initialize the Vmb API //CRASHES HERE!
fmt::print("RETURNED from calling startup()\n"); //Never reach this line of code
The callstack / backtrace from gdb debug mode shows the crash occurring inside of VmbC.so.

The Vimba examples from the SDK compile, link, and run without a problem on the same Ubuntu 20.04 install. This leads me to believe that one of the other libraries my application links to may conflict or perhaps cause some ODR violation as a result of transitive dependencies? I require Boost-1.8x and am using OpenGL and other cross platform libraries… The LDD tree output of my exe looks like:
I am using GCC 13.1 as my C++ compiler.

Thanks,
It seems VmbC has a problem with certain boost versions. Not sure what’s the latest one supported officially, I thought ist was 1.7. If Boost-1.8x is linked statically I’d suggest to link it dynamically if applicable.
Norman,
Thank you for the reply. I have switched my build process to dynamically link my test executable to boost 1.83. To verify, the lddtree -l command now shows /usr/local/lib/libboost_thread.so.1.83.0 as a dynamically linked library.

It appears Vimba uses a Singleton to initialize itself. From the usage, the Singleton may be implemented as a Meyers Singleton. Could some type of static initialization problem be occurring?
For fun, I created my own Meyer’s Singleton and called Vimba Startup() as soon as possible. Below is the source code I am using as a test:

s.sys.QueryVersion(versionInfo);

The Singleton class above invokes Vimba Startup() before main() begins – still crashes and this is the first thing to be done as far as I can tell. Of course, I’ve tried calling StartUp() as a normal function call in main as well. In both cases, Vimba crashes in the same way.
Do you have any other ideas or things to try? We’ve spent about 17 hours debugging this issue – all works perfectly on Windows. On Linux, the standalone Vimba exes work properly and our application works properly. As soon as Vimba is linked into our exe, the Startup() fails immediately.
Norman,
I was able to use Valgrind and get some additional information. It appears Valgrind reports Vimba’s initialization is using uninitialized memory inside of VmbC.so and subsequently crashing. Perhaps the stack dump below created via valgrind --track-origins=yes -s ./NewModule may be helpful.
I’d appreciate any help – we are “shipping” this week and our target CPU doesn’t yet support windows, so we are stuck on linux.

I just opened up a support ticket, asking for quick help internally.
Please confirm you’re running VmbCPP API 1.0.2 from 2023-1 setup?
Ok, that can be assumed.
It turnes out that VimbaUSBTL.cti is the only VimbaX component with boost dependencies, loaded at VmbStartup(). As you could surrender USB support for now just try to delete VimbaUSBTL.cti from your cti folder. Any changes?
I am using VmbCPP API 1.0.2 from 2023-1 setup, yes.
I do not require USB. When I remove VimbaUSBTL.cti from my install, the behavior, sadly, remains unchanged.
There are two different behaviors I am observing. The first behavior seems nearly correct and is described here:
When I write a simple program that initializes Vimba, I can make it work so long as I avoid including a header from to our application’s library into the compiled executable. When I do this, Vimba initializes properly and provides this output.
Here is the CMake file for the simple main.cpp only program which includes all the dependencies we ultimately must link against:

It appears that the above code may properly work, however, I must include a header file for our internal application that compiles into this .exe. I will post that behavior next. Including this header file works correctly on windows (and has been for months using both the older 2022 Vimba X API and the 2023 API). On Windows, our product is ready to ship. However, on Linux, this exact same code then causes the Startup() command to segfault. I will post more in my next post now.
Our internal application also uses a few Meyer’s singletons to initialize various other parts of the application, like GLEW and other utilities that are unrelated to Vimba.
For clarify, here is the exact same main.cpp run again through valgrind as it crashes on exit:

When VIMBA SEGFAULTs on Startup()
As I mentioned above, the simple main.cpp appears to initialize properly. The crash on exit may not affect acquisition during runtime, so I will pretend that is currently not a problem.
Now, if I modify the CMake file above to also compile a translation unit that include our business logic for using the camera, the Startup() fails. Here is the relevant change to the above CMakeLists.txt
add_executable(vexe main.cpp bar.cpp GLViewNewModule.cpp )
bar.cpp is simply a stub file that avoids including the header file for GLViewNewModule.cpp inside of main.cpp. I believe this is unnecessary and have never had to use this approach in the past 18 years of programming with our AftrBurner API, but for the sake of isolation, I ensured main.cpp did not include any header files from our internal AftrBurner API (C++ 3D visualization engine).
Here is the contents of bar.cpp:
#include "GLViewNewModule.h" //GLView subclass instantiated to drive this simulation
#include <memory>
#include <vector>
#include <string>
void bar( std::vector<std::string> const& args )
{
int simStatus{0};
do
{
std::unique_ptr<Aftr::GLViewNewModule> glView(Aftr::GLViewNewModule::New(args));
simStatus = glView->startWorldSimulationLoop();
} while (simStatus != 0);
}
Now, the only change to main.cpp is a call to bar() (after the call to foo(), the code is the same as above with one additional function call in main():
int main(int argc, char *argv[])
{
std::this_thread::sleep_for( std::chrono::seconds(2) );
foo();
std::vector<std::string> args{argv, argv + argc};
bar( args ); //THIS IS THE NEW CALL
std::cout << "Exited AftrBurner Engine Normally..." << std::endl;
return 0;
}
Now I compile and link (no warnings, no errors). When I run the executable, I see:

When I run again in Valgrind with very verbose options, I can see some internal Vimba callstacks that may be helpful. There is also some reported memory leaks inside AftrBurner and Vimba, but keep in mind, the exe crashes, so the d’tors are never called:

The Vimba Startup immediately failes with status -3 and the rest of the application loads and functions completely normally – the 3D rendering works and all other parts of the software work. But we cannot init Vimba nor connect to the cameras.
Of course, one isn’t supposed to launch the Vimba examples with sudo as that causes Vimba Startup() to report the designated instance cannot be found.
Any thoughts or ideas? I am more than willing to download an unofficial patch from any willing devs for ARM64 Ubuntu who can perhaps fix the init. I hope the verbose valgrind callstacks can point to a useful hint within the Startup (I had to trim down some output so this post would fit in 32,000 chars)
In the valgrind output, there appears to be use of an Vimba XML parser as well as boost condition variables, mutexes, and other threaded things – of course, these can be very tricky to manage during static initialization.
Thanks,
Scott
For fun, I’ve turned on -fsanitize=address and run the program when linked to my AftrBurner library and when not linked. The only change is the static link. The main.cpp still immediately calls vimba’s Startup() via foo().

Before completing foo(), the Vimba driver appears to dereference an invalid memory location. I believe there may be some place in the Vimba driver that potentially has a bug and is affected by the binary layout changed when linking several static binaries together??
Here is the output with -fsanitize=address showing the problem.

If I remove the link to my static library from cmake, and run again, the library properly initializes:
user@AFIT-Jetson-20:/repos/aburn/usr/hub/Vexe/bg$ ./vexe
In main
Calling shutdown...
done calling shutdown...
Calling startup...
Startup() result is 0
RETURNED from calling startup()
Startup successful
Vmb Version Major: 1 Minor: 0 Patch: 2
Exited AftrBurner Engine Normally...
Again, no function from the library is ever called or used (I commented out the call to bar()). The library is only linked and then the behavior of Vimba’s Startup() is affected.
Hopefully this provides a hint as well.
Thanks,
Scott
