I have created an app using sqlite3 library. The app works as expected and i have had no problems using mkapp and its update file. When i am trying to use mksys instead, to link three apps together, i am getting error saying “undefined reference to …”.
To use sqlite I created a sqlite.so file using gcc and flags like lpthread. One of the undefined references seems to be pthread. Does anyone know why this becomes a problem when using mksys but not mkapp?
I still get the same error after adding .adef to wifi.sdef. Here is how the error is shown:
checking whether the C compiler works... no configure: error: in /home/sindrekvande/LegatoWorkspace/ths_gw_system/_build_neuronEthernetLteGW/wp76xx/component/37b16d9818aa215e8b1d383409c34f3c/lighttpd: configure: error: C compiler cannot create executables See config.log for more details ninja: build stopped: subcommand failed.
By looking in config.log i can see “undefined reference to (for example pthread functions)”. Could this mean that i have added the sqlite3 library wrong? Sqlite3 uses pthread library, so when I created sqlite3.so I used gcc and flags like lptrhread. Using this file worked well using mkapp. Using mksys it seems like it finds a reference to the used sqlite3 functions, but not libraries which is included in the sqlite3 library.
`checking whether the C compiler works... no`

your error in “make wp76xx” is related to lighttpd…
Not sqilte stuff
Sorry, I showed only one of the errors. Here is the first error, and why I think it is sqlite aswell.
checking for doxygen... :

checking whether make sets $(MAKE)... yes

If you mean using the makefile by that, here are the results with your app:

I also tried to make .so again, but it did not work.
