Question:
When running a CasePlayer2 analysis to create documents, I get the following "CasePlayer2-E-SYN : ; expected." message. How can I fix it?
Answer:
This error occurs when the source code includes descriptions incompatible with the ANSI-C standard, such as compiler specific keywords. Since CasePlayer2 doesn't recognize the keyword, it cannot analyze the statement correctly and this error is displayed.
The following sample message indicates that line #2 of etos.c contains an incorrect description.
CasePlayer2-E-SYN : ; expected.
C:\Program Files\GAIO\CasePlayer2\sample\C_program\etos.c(2)
For example, the following line would cause this error.
direct int var1;
The "direct" statement is a compiler specific descriptor and is incompatible with ANSI-C. Therefore, an analysis error occurs.
It is possible to register non-standard keywords in CasePlayer2 to fix the error.
In this case, we can set CasePlayer2 to treat "direct" as a keyword to specify a storage class.
In the "Settings" tab, double-click "C Option Parameters", register the following in the "User Keyword" window.
Keyword: direct, Type: STRAGE, Postfix description: (empty)
The "User keyword" and "Replacement keyword" settings are stored in the *.rvc file. The *.rvc file is a text file automatically generated in the CasePlayer2 project folder (the folder where the *.vproj file is located). See the example below.
Additional Examples
INT32 val;
Register "INT32" keyword as "TYPE" type to analyze as a type.
Keyword: INT32, Type: TYPE, Postfix description: (empty)
near int p1;
Register "near" keyword as "TYPEATT" type to analyze as a type modifier.
Keyword: near, Type: TYPEATT, Postfix description: (empty)
__asm (" ....... ")
Register "__asm" keyword as "ASM" type to analyze as an inline assembly description.
Keyword: __asm, Type: ASM, Postfix description: (EXPRESSION)
#define _ARMABI __declispec(__nothrow) __pure
_ARMABI volatile int *func(void);
Register " __declipsec" and "__pure" keywords as "IGNORE" type to ignore during analysis.
Keyword: __declipsec, Type: IGNORE, Postfix description: (EXPRESSION)
Keyword: __pure, Type: IGNORE, Postfix description: (empty)
