# How to configure libshim ?
Libshim is divided into bits which will generate `LINKER_FORCED_SHIM_LIBS` for you, you don't need to `export LD_SHIM_LIBS`.
The only configuration libshim needs is the following flags :
### > Libshim flags
WIP: just export your shims in init.mtxxxx.rc for now
Copy & paste these flags in your device tree `BoardConfig.mk` : (uncomment the flags you need)
`#LIBSHIM_XLOG_SYMBOLS :=true`
`#LIBSHIM_SND_SYMBOLS := true`
`#LIBSHIM_UI_SYMBOLS := true`
`#LIBSHIM_GUI_SYMBOLS := true`
`#LIBSHIM_OMX_SYMBOLS := true`
`#LIBSHIM_BIONIC_SYMBOLS := true`
`#LIBSHIM_BIONIC_SYMBOLS := true`
`#LIBSHIM_AGPS_SYMBOLS := true`
`#LIBSHIM_ATOMIC_SYMBOLS := true`
(copy/paste in `BoardConfig.mk` & uncomment the flags you need)
# Optional :
- building TWRP in LOS-15.x tree (temp fix) : `patches/optional/0001-TEMP-TWRP-fix-recovery-build-with-f2fs-on-LOS-15.x-t.patch`
