I had to use it for SFOS packaging, but it shouldn't be needed for you.
Tried that, still the same errors (at least AFAICT):
Code:

Googling for "relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC" uncovered some discussion about cases in other programs when trying to link relocatable and non-relocatable code together, so I wonder if we are seeing something like that as well. Looking at the test subfolder where this is happening, it seems to have some custom flags defined here:
https://github.com/openvenues/libpos...st/Makefile.am
So maybe it compiles the testing code wrong or something like that ?
Also I wonder if the tests could just be disabled, but that feels like a hack.

Yes, that's what I think OSM Scout Server is best in the world at - making all the power of the existing open geodata & libraries seamlessly available both to application developers (language independent & well documented common API) and users (super easy offline data downloading & updates + data sharing with all apps using the OSM Scout Server API).

I don't think any existing solution can come close to this - otherwise developers would have to handle every lib themselves (compilation/packaging/bundling) & library APIs are often limited (C/C++ only, API that requires a heavy server software to run, etc.), not to mention all the hassles with offline data management that would have to be solved more or less separately for every application.

From the user side, there is super easy & unified offline data management & all the nice features made possibly by the easily accessible APIs.
