I'm trying to link a simple app_main() against some prebuilt libraries, using the method described in the last post (by dmarks_ls) in this thread:
https://esp32.com/viewtopic.php?t=16452
The linking stage of the build throws a bunch of errors with "dangerous relocation: call8: call target out of range".
This probably means that my library is built with the wrong compiler flags, can anyone give a pointer to where I can find the correct flags to use?
The libraries are built using Makefiles. Currently I am not using an IDE (I plan to use vscode, but I prefer to get things working on the command line first and worry about IDE integration later). Here is a sample gcc command so you can see the flags which are being used:
