＆＃34;多种目标模式＆＃34;犯错误

Question

我在编译improved trajectories

时遇到此错误

.build_release/DenseTrackStab.l:2: *** multiple target patterns. Stop.

.build_release / DenseTrackStab.l文件：

-include .build_release/DenseTrackStab.d
.build_release/DenseTrackStab.l: \
    .build_release/DenseTrackStab.d \
release/DenseTrackStab: .build_release/DenseTrackStab.l \
    .build_release/DenseTrackStab.o \
