[SOLVED] Shared library build: error linking on `libspdlog.a`, recompile with -fPIC about depthai-core HOT 4 CLOSED

removing the hunter cache and previous build directory worked.

[ 96%] Linking CXX shared library libdepthai-core.so
[ 96%] Built target depthai-core
Scanning dependencies of target depthai-opencv

The problem is after building shared libs, rtabmap is not detecting them - manually defining the install folder
while building rtabmap fixes that.
cmake .. -Ddepthai_DIR="/home/notyou/depthai-core/build/install/lib/cmake/depthai"

from depthai-core.

Tried this and see "can not be used when making a shared object; recompile with -fPIC.
Attempting to use the OAK-D again with RTAB-Map. The depth-ai compiles in static build mode, rtabmap doesnt find it and cmakes as normal. I did managed to build it earlier in the year but things have changed since then.

@rlabs-oss can you share more details - the steps you've taken after removing the Hunter cache directory as well as any relevant output of the commands that you've executed.

@rlabs-oss correct, this is desired behavior. We've opted for installing to a build local directory by default instead of system directory, to not clutter the system with older versions, etc...

One can also specify the -D CMAKE_INSTALL_PREFIX=/usr/local which will cause the installation to be done in the specified folder. This also requires sudo when executing install target
