Hi Augustin,

Thanks a lot. It really works after doing
gcc replay_multiple.c -o replay_multiple *-lsimgrid
-I/opt/simgrid3.21/include -I/opt/simgrid3.21/include/smpi
-L/opt/simgrid3.21/lib*
(-L/opt/simgrid3.21/lib is a must)

Then after *export LD_LIBRARY_PATH=/opt/simgrid3.21/lib*, the simulation
can be successfully run as follows.

smallcat at DESKTOP-PVCKLS6:/mnt/c/Users/huyao/OneDrive/ドキュメント/GitHub/simgrid/simgrid3.21-examples/smpi/replay_multiple$
./replay_multiple description_file ../../platforms/small_platform_with_rou
ters.xml deployment.xml --log=smpi.:info --cfg=maxmin/concurrency-limit:100
[0.000000] [xbt_cfg/INFO] Configuration change: Set
'maxmin/concurrency-limit' to '100'
[0.000000] [smpi_kernel/INFO] You did not set the power of the host running
the simulation.  The timings will certainly not be accurate.  Use the
option "--cfg=smpi/host-speed:<flops>" to set its value.Check
http://simgrid.org/simgrid/latest/doc/options.html#options_smpi_bench for
more information.

Thanks very much again for your patience!
