attempt to call a nil value (global 'simExtCHAI3D_start')

[zhangm365]

I copy the v_repExtCHAI3D.dll in V-REP( 64 bits )，and it can load "CHAI3D" plugin successful. But when I start the simulation，the error happen : [Pioneer_p3dx@childScript:error] [string "Pioneer_p3dx@childScript"]:33: attempt to call a nil value (global 'simExtCHAI3D_start') stack traceback: [string "Pioneer_p3dx@childScript"]:33: in function 'sim_code_function_to_run'

How to fix it?

Hello,

try to rename those CHAI functions from e.g. simExtCHAI3D_start to simCHAI3D.start

[zhangm365]

Yes, I changed it to "simExtCHAI3D_start" to "simCHAI3D.start" in file ...\chai3d-3.2.0\modules\V-REP\src\v_repExtCHAI3D.cpp, but when I run the demo( 02-V-REP-Pioneer.ttt ) in the V-REP, it was the same error as follows:

simCHAI3D, not simExtCHAI3D! Also, make sure the CHAI3D plugin was successfully loaded

[zhangm365]

Yeah，the CHAI3D plugin is successfully loaded

But the same error :

Ok, so it seems you are compiling the plugin yourself. Are you using the correct plugin source? From your previous comment (_"Yes, I changed it to "simExtCHAI3D_start" to "simCHAI3D.start" in file ...\chai3d-3.2.0\modules\V-REP\src\vrepExtCHAI3D.cpp") it seems you are using a different source

Let's continue that discussion on the forum, as it seems you have posted there too

[zhangm365]

Yeah, I have posted the bugs in the forum. Thank your help!
