I tried building against 1.3.6 (mainly because it was laying around) and the error reported by Devrim is just the tip of the iceberg. With "make -k", I see unknown-symbol failures on ZSTD_CCtx_setParameter ZSTD_c_compressionLevel ZSTD_c_nbWorkers ZSTD_CCtx_reset ZSTD_reset_session_only ZSTD_compressStream2 ZSTD_e_continue ZSTD_e_end I wonder whether Robert's ambition to be compatible with old versions extends that far. regards, tom lane
