[BUG] Relocation error #1196

Closed flabrosse closed 3 months ago

I am trying to compile the latest version of depthai_core (from github, today, 13/08/2024) and at linking time I get a lot of:

[ 97%] Linking CXX shared library libdepthai-core.so

I didn't use the script (as I like seeing what is going on given how long it takes to compile) but replicated the same instructions.

This is on ubuntu 22.04 on a Raspberry Pi 4.

Clearly, using the standard

mkdir build
cd build
cmake ..
make
make install

is not quite equivalent to what the script does. I just did a verbatim copy of the script and it worked. Not sure I understand, but it complied, linked and installed.
