#Cmake library path install
#Cmake library path full
#Cmake library path windows

Note that if the project is built on the Windows side, you would need to use the $” in target_link_libraries() means “the library pointed by the sqlite3 variable” and “sqlite3” would mean “ libsqlite3.*“.

#Cmake library path full

Once you have located the library, add its full path to the Linked Libraries field under the VS properties for your main CMake target.

This can be done by either checking the sqlite3 documentation, or searching for all libraries on Raspberry Pi for the name of the missing symbol ( sqlite3_initialize):

In order to fix the “ undefined reference to ‘sqlite3_initialize’” errors, we need to locate the library that defines those symbols.

As we have included the header files (that provide the definitions for sqlite3_xxx() functions), but have not referenced the library defining them, the linker will fail due to missing definitions for the sqlite3 functions:

Replace the contents of the main source file with the following basic project demonstrating the use of sqlite3:.

This will copy the sqlite libraries from the Raspberry Pi into the toolchain so that you can reference them from the projects built with that toolchain: Once it is created, open VisualGDB Project Properties and click “Synchronize Sysroot” on the CMake project settings page.

Ensure the “test connection” checkbox is checked so that VisualGDB can check that all the necessary packages are present:

On the next page select your Raspberry Pi cross-toolchain and pick the SSH connection for your Pi.

On the first page select “Create Application -> CMake -> Ninja”:.

Start Visual Studio and open the VisualGDB Linux Project Wizard:.

If you are using SmarTTY, the Tools->Manage Linux Packages command can help you find the exact package name easier:

#Cmake library path install

Connect to your Raspberry Pi via SSH and install the libsqlite3-dev package.

In this tutorial we will use Visual Studio and VisualGDB, however the steps described below will work with any other CMake-based environment. We will create a basic Raspberry Pi project using the sqlite3 library and will then show different ways of using target_link_libraries() to reference the necessary libraries.

I will look at this again.This tutorial shows various ways to use CMake’s target_link_libraries() statement and explains the differences between them. As these still failed, I deleted the extra flags in my CMakeList.txt. But this was no solution in my case as I also need the example tools build with library X. I linked one of my several CMake tagets with -Wl,-enable-new-dtags which seemed to solve the problem. LibvtkCommonComputationalGeometry-8.2.so.1 => not found VTK and library X using VTK are compiled with mkdir build Same result for “locate” after “sudo updatedb”. LibvtkFiltersGeometry-8.2.so.1 => not found LibvtkFiltersSources-8.2.so.1 => correct full path to library Running ldd on the resulting executable gives: The RPATH is not set … and LD_LIBRARY_PATH does not contain “/home/me/opt/vtk/lib” (and I would rather not set LD_LIBRARY_PATH - although I will if I have to). Project(“Display Sphere Example”) set(VTK_DIR /home/me/opt/vtk/lib/cmake/vtk-8.2)Īfterwards, the executable built without error, but when running it, it appears that there are some VTK libraries that are not found (and confusingly, some are found)? Running “readelf -d” on the resulting executable gives the correct RUNPATH: I did not use the CMakeLists.txt file in the example, but I did use it as a guide for what I wrote: I copied the sphere example into a directory. My system is Ubuntu 19.10, with kernel 5.3.0-42-generic. I built VTK from source (8.2.0) and I am using CMake 3.13.
