HelloWorld running issue

[catalinolteanu]

Hi,

I've built the HelloWorld(described in the wiki), for vsomeip3. After a small change in CMakeLists(for linking with vsomeip3 and some generated cpp file name), I managed to have two binaries(HelloWorldClient and HelloWorldService).

I've configured the /etc/commonapi.ini to something like:
[default]
binding=someip

[logging]
console = true
file = ./mylog.log
dlt = false
level = verbose

Now, I have this output, that shows missing the test library and configuration module:
@catalin-virt:/sources/genivi/project/build$ [CAPI][INFO] Loading configuration file '/etc/commonapi.ini'
[CAPI][INFO] Using default binding 'someip'
[CAPI][INFO] Using default shared library folder '/usr/local/lib/commonapi'
[CAPI][DEBUG] Added address mapping: local:commonapi.HelloWorld:v1_0:test <--> [1234.5678(1.0)]
[CAPI][INFO] Registering function for creating "commonapi.HelloWorld:v1_0" stub adapter.
[CAPI][DEBUG] Loading library for local:commonapi.HelloWorld:v1_0:test stub.
[CAPI][DEBUG] Loading interface library "liblocal__commonapi_HelloWorld:v1_0__test.so" failed (liblocal__commonapi_HelloWorld:v1_0__test.so: cannot open shared object file: No such file or directory)
[CAPI][INFO] Registering stub for "local:commonapi.HelloWorld:v1_0:test"
Configuration module could not be loaded!

What should I do now to make the sample to communicate between client and service ?

Thank you !

export LD_LIBRARY_PATH to build folder fixed the issue.

Because there is nobody to install the samples in there linux systems, I think should be specified somewhere in the wiki that LD_LIBRARY_PATH setting.

@catalinolteanu I experience the same issue but for me the "export hack" doesn't work. Any other more detailed remarks on this? I went to the build folder and exported the path but this doesn't change anything. If I spare out the commonapi.ini file the whole server will be run on dbus (which is the default as far as I understand) and therefore doesn't cause the error. So it seems to be something within the someip-tools stack that causes this which can't be solved by the "hack".

[Pixelfahnder]

The weird thing though is, that the code still works, but the message is irritating and maybe there may be a way of getting rid of it?

You probably had to add next lines into your ini files:

[stub]

local:commonapi.HelloWorld:v1_0:test=/path/to/your/library/v1_0__test.so

local:commonapi.HelloWorld:v1_0:test
v1_0__test.so is the library which is being build from generated code.

I meet the issue too, I don't know the correct path where v1_0__test.so is located , I searched all files but not found v_1__test.so anywhere. Could you help it ?

[stefanoltean1]

Same issue from my side. Is there a more comprehensive guide to solve this?

[goncaloalmeida]

hello,
@stefanoltean1 / @memoryleake please use the last release of all projects.
this issue is still occurring with the last release?

I know how to fix , we need config commonapi.ini file's [stub] and [proxy].
for example:

local:commonapi.HelloWorld:v1_0:test=xxx-someip.so

and this path is from your generate code xxxSomeIPproxy.cpp:
for example:

void initializeHelloWorldSomeIPProxy() {
    CommonAPI::SomeIP::AddressTranslator::get()->insert(
        "local:commonapi.HelloWorld:v1_0:test",   // this is we need
        0x1234, 0x5678, 1, 0);
    CommonAPI::SomeIP::Factory::get()->registerProxyCreateMethod(
        "commonapi.HelloWorld:v1_0",
        &createHelloWorldSomeIPProxy);
}

@goncaloalmeida Newest version also has this issue, I have this issue as well.

    CommonAPI::SomeIP::Factory::get()->registerProxyCreateMethod(
        "commonapi.HelloWorld:v1_0",
        &createHelloWorldSomeIPProxy);
}

How do you fix this issue? As your comment, I add one line in commonapi.ini
local:commonapi.HelloWorld:v1_0:test=HelloWorld-someip.so
it seems the issue still there, do you have any suggestion, thanks.

According to CommonAPI's source code, name of binding library to be searched is configurable.
By default it's liblocal__<namespace>_<service>:<version>.so

But you can change it by setting the property for your service (directly in cpp code)

CommonAPI::Runtime::setProperty("LibraryBase", "<service>");

Then it will be <service>-someip.so (or DBus; it depends on used binding)

Here is responsible snippet

    library = getProperty("LibraryBase");
    if (library != "") {
#ifdef _WIN32
        library = library + "-" + defaultBinding_;
#else
        library = "lib" + library + "-" + defaultBinding_;
#endif
    } else {
        library = "lib" + _domain + "__" + _interface + "__" + _instance;
        std::replace(library.begin(), library.end(), '.', '_');
    }

The CMakeLists.txt file was updated and a new line was added: "set(PRJ_NAME HelloWorld)".
Please verify if it's now working as expected. Otherwise please indicate all the changes you have done in CMakeLists.txt.
