Problem with adding new files to INET (<!> Error: Cannot load library)

[Meghna2069]

Hello !

Please, I need your help with the following issue, actually, each time i create a new module under inet i get the following error: "<!> Error: Cannot load library '/home/laptop/artery/build/src/artery/envmod/libartery_envmod.so': /home/laptop/artery/build/extern/libINET.so: undefined symbol: _ZTIN4inet9ieee802114glvfE"

I do not understand what is the reason behind this error, although i enter make cleanall and make makefiles each time i add a new file, i am always getting this error and i do not think that it is a coding issue because when i put the same code in files that already exist under inet, i do not get this error, what shall i do please, it's been days now since i faced this error and i can not move on !

Thank you very much in advance for your help !

Artery builds INET for you, i.e. you should not need to manually invoke any INET make targets. What happens when you simply build Artery after adding your new module to INET?

Also, your error occurs at runtime. Possibly the reason is actually a problem when compiling the sources. Do you see any error or warning messages during the build?

Thank you for replying !

Here are the warnings i see when i run my project:

"

The problem is that i do not see my modified files, neither do i see the ones i added during compilation and then i get the message error that indicates that it can not load library !

Do you think that the error might exist in the code ? Aren't they any other reasons behind this compilation error ? and why i do not see the files i added during execution of my project ? Have you got an idea about that please ?

When adding new files to INET you will need to run the configuration stage of CMake again, i.e. go to your build directory and invoke cmake .. there. This step will search for all source files found in the extern subdirectories and add them to the build target. A follow-up build will then include also the new source files.
