I have integrated CLIPS with VC++(MFC), why there are some function does't execute,such as “strcmp”
It looks like you're using a beta version of CLIPS 6.30 rather than the release version (clips_windows_projects_630.zip from http://sourceforge.net/projects/clipsrules/files/CLIPS/6.30/). The DLL doesn't expose the router functionality, so it's unclear how you could get your code to compile if you're embedding CLIPS in the same manner as the WrappedDLLExample. The following...
When compile the CLIPS integration source code,the CLIPSStatic in the CLIPS Solution is failed
visual-studio-2012,integration,clips
You're using the wrong projects/solutions. Download the latest commit (r281). The solution folders in the microsoft_windows directory that you want to use are CLIPS_MVC_2010, CLIPS_MVC_2013, Examples_MVC_2010, and Examples_MVC_2013. Since you're using Visual Studio 2012, you'll probably want to use the 2010 directories. The instructions in the Advanced Programming Guide specifically...

How to use not condition in CLIPS programming language properly?
As written the not conditional element prevents the rule from executing if the fact (bird ostrich) is present. Since that fact is present once you perform a (reset), the rule does not execute. If you want the rule to execute for each bird fact where ?var is not ostrich, you...
How to change the match algorithms in CLIPS
The architecture manual for CLIPS 5.1 is available here: http://clipsrules.sourceforge.net/documentation/other/arch5-1.pdf. It's not for the most recent version of the code, but a great deal of the information is still relevant, particularly for descriptions of the source code files. For constructing the rete network, the more important files are analysis.c, factbld.c,...
How do I have a program in CLIPS assert user input without having the user type assert(whatever))

return two values in clips function
Use create$ to place multiple values within a multifield value. You can then use nth$ to retrieve individual values: CLIPS> (deffunction direction () (return (create$ 1 -1))) CLIPS> (direction) (1 -1) CLIPS> (nth$ 1 (direction)) 1 CLIPS> (nth$ 2 (direction)) -1 CLIPS> ...
JESS Userfunction writes “BS” instead of “/home” to a file
The unquoted text /home/ is being parsed as a regular expression; the printed value is somewhat unpredictable. You need to include double quotes in your built-up command so the path is seen as a quoted string.
Can I compare existing fact values to random numbers on the RHS of a defrule?
You can use the fact query functions on the RHS to determine if a fact exists for a specific move: (defrule First_Three_Moves "Used for the first 3 moves of the game" ?f <-(turn_num ?t_num) (next_turn p) (or(turn_num 1) (turn_num 2) (turn_num 3)) => (bind ?move (random 1 24)) (while (any-factp...

Cant make 'not' and 'eq' work together
You need to use the test CE to evaluate expressions in the conditions of a rule. For example, instead of (not (eq ?sp ?p2)) use (test (not (eq ?sp ?p2))) or (test (neq ?sp ?p2)) Your existing rules are attempting to match a fact with relation name eq rather than...
Taking all values of multislot slot using the fact-address in CLIPS

Per Gary's comment: The shorthand syntax for retrieving slot values can only be used in the fact-set query functions. Use "(fact-slot-value ?f changeinfo)" instead of ?f:changeinfo...
Find the maximum of the facts in the clips SATISFYING THE CONDITION
In your find-max deffunction where you had TRUE, you need to place your condition there instead. The test CE element, (test (eq ?oper 2)), you placed within the function only work within the conditions of a rule.

How can other defmodules import defclass and deftemplate from MAIN
This is the relevant passage from section 10.1 of the Basic Programming Guide: All of the predefined system classes (see section 9.2) belong to the MAIN module. However, it is not necessary to import or export the system classes; they are always in scope. Discounting the previous exception, the predefined...

What types of files can CLIPS open
You can use the open command to open a file for reading in either text or binary mode. If you opened a xlsx file in binary mode, you could use the get-char function to retrieve individual characters from the file. There's no built-in functionality for parsing a xlsx file, so...
how to force Clips to stay at the rule until is totally finished with the data without redundancy?
The exact behavior you want is not clear from your question, but here's one technique for querying the user, printing all the results, and then determining if another query should be performed.

Checking the input to match fact in Clips
You've defined symptom as a multifield slot (a slot containing zero or more fields), but your patterns matching those slots will only match if the slot contains a single field. Use a multifield variable such as $?symptom1 instead of a single field variable such as ?symptom1 to retrieve multiple values....
Fuzzy facts in clips
By having overlapping ranges it kind of makes sense. But maybe overlapping isn't what you want to do. What about: (deftemplate fz-knowledge 0 100 ( (low (20 1) (40 0)) (high (60 0) (80 1)) (med NOT [ low OR high ] ) )) That way, you can clearly tell...
CLIPS: forcing a rule to re-evaluate the value of a global variable?
Don't attempt to use global variables or function calls in this manner. First, global variables are specifically designed to not trigger pattern matching. Second, it would take a bit of magic for CLIPS to know when a function call needs to be reevaluated as there are any number of changes...
Generalization of set of facts in CLIPS (trying to find matching slot values in multislot slots)

CLIPS 6.3 internally supports UTF-8 strings, however, the application embedding CLIPS must also support UTF-8 I/O. The CLIPS Windows IDE does not support UTF-8 I/O.

CLIPS defrule checking if multiple sides of a box are taken
I would suggest explicitly representing each possible line as a fact and denote in the fact whether the line has been taken. Also do the pattern matching in the conditions of the rules rather than the actions. CLIPS> (deftemplate line (slot id) (slot taken (default no))) CLIPS> (defrule Player_Move_Top_Line ?take...
