compiling all models, all such problems,why?

The compiler detected synter
errors
Would you like to open Visual C++;
This facilitates checking the syntax

It says that you have syntax error in your model. That's why Flexsim will start C++ to check them.

One hint I can give you right away:
NEVER start Flexsim models directly from the Explorer.
First open Flexsim and then open the model.

If this is not helpful, I guss the community needs more information. Which model you like to run, etc.

thanks I do it as you say First open Flexsim and then open the model but also such problems, yesterday it is good ,but today compiling go wrong. other computer compiling model well but my computer can not compiling this model well

This applies to no-member functions

Did you try Build / Compile Entire Session?

This sometimes helps. Otherwise it is strange that compile worked yesterday, but not today.

yse ,Compile Entire Session ,because my ct library can not show , someone advise me Compile Entire Session .right now i can do what make it work well

hi Tom David ,can you help me ?? thank you and i want know why can not use Compile Entire Session ?

hi Tom David ,can you help me ?? where are you
???

I am not sure what you mean with where am I.

I am sometimes here in the Forum and try to help by answering posts.

I thought your problem is solved after using Compile Entire Session.
Otherwise I have no idea in the moment how to help you.

By the way, I did not use Flexsim CT, so I can not answer any questions about CT.

i Reshipment flexsim software and solve it thank you Tom David

What do you mean by "Reshipment"?

I am asking, becaue someone else might have a similar problem and it would be nice if he can find here in the Forum how you solved the problem.
That's what the Forum is for. So if a problem is solved it would be nice to understand what solved the problem that people can find help here.
