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…

I found that the problem is in .cdef, you cannot add requires: { lib: { ../third-party/lib/libsqlite3.so } } Otherwise, it will have multiple definition problem during compilation in R16 package. (not quite understand the root cause as no problem is found for compilation in R1…

how about embed the application to legato.cwe? [image] Flash size wp7607 you can go to legato-19.02.0/modules/WiFi/wifi.sdef, under “apps:” section, add e.g. $LEGATO_ROOT/apps/sample/helloWorld/helloWorld.adef [image] Now the new app will be included in legato.cwe. …

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: conf…

when you do mksys, did you together make the “libsqlite3.so”? I remember when I build the “libsqlite3.so”, I need to add "-lpthread " in the Makefile. Or your .adef and .cdef just add bundling of the libsqlite3.so? e.g. .adef bundles: { file: { [r] third-party/lib/libsqlite3.so /lib/ } }…

When i do mksys i use the same “libsqlite3.so” as i created for mkapp. I created it like this: export TOOLCHAIN_DIR:=/opt/swi/SWI9X07Y_02.37.07.00/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi GCC = ${TOOLCHAIN_DIR}/arm-poky-linux-gnueabi-gcc all: ${GCC} -c -Wall -Werror -fpic -l…

Yes, but if i remove the parts where I use the sqlite3 the makefile works as expected

then you can modify adef and cdef to see which line makes the problem

Sorry, I showed only one of the errors. Here is the first error, and why I think it is sqlite aswell. /home/sindrekvande/LegatoWorkspace/apps/neuron_iotgw/sqlite3/lib/sqlite3.so checking for doxygen... : checking for etags... /bin/false checking whether make sets $(MAKE)... yes checking for arm-pok…

Can you try with this app to embed in legato image? [image] Database Support I can compile with attached application. The makefile of sqlite is using WP76 R9 toolchain. The legato application is successfully compiled in WP76 R10.1. testsql.7z (2.8 MB)

If you mean using the makefile by that, here are the results with your app: /home/sindrekvande/LegatoWorkspace/testsql/third-party/lib/libsqlite3.so: In function `sqlite3_global_recover': sqlite3.c:(.text+0xd2748): multiple definition of `sqlite3_global_recover' /home/sindrekvande/LegatoWorkspace/t…
