[SOLVED] Unable to run demo example

[C47D]

Hi,

First time trying to get the demo example running, I followed the README instructions (also copied lv_conf.h and lv_drivers_conf.h to this repo root dir) but ended up with this error (similar to #152). There seems to be an empty -D after DLV_CONF_INCLUDE_SIMPLE:

$ DEP_LV_CONFIG_PATH=`pwd` cargo run --example demo --features="alloc"
   Compiling lvgl-sys v0.6.2 (/home/d3bug/Desktop/lv_binding_rust/lvgl-sys)
The following warnings were emitted during compilation:

warning: lvgl-sys@0.6.2: <command-line>: error: no macro name given in #define directive

error: failed to run custom build command for `lvgl-sys v0.6.2 (/home/d3bug/Desktop/lv_binding_rust/lvgl-sys)`

Caused by:
  process didn't exit successfully: `/home/d3bug/Desktop/lv_binding_rust/target/debug/build/lvgl-sys-3e9d9eb4b2672d68/build-script-build` (exit status: 1)
