问题描述
Hi
刚开始使用VS2008 C ++
我正在尝试从旧的C ++项目编译代码进入Windows窗体项目。当我编译时，我得到一个类的几个对象的LNK2028错误。 Class在CLASSES.h文件中声明，但似乎在SIGNAL.cpp文件中未被识别。这是几个典型的错误：
错误1错误LNK2028：未解析的令牌（0A000009）void * __clrcall memrealloc（void * ，unsigned int）（？memrealloc @@ $$ FYMPAXPAXI @ Z）在函数public：int __clrcall Signal :: undo_difference（class Signal *）（？undo_difference @ Signal @@ $$ FQAMHPAV1 @@ Z）SIGNAL中引用。 obj
这是头文件FUNCDEFS.h中的令牌（我认为！）声明：
extern void * memrealloc（void * ptr，unsigned int size）;
EXTERN.h中的代码因此：
extern TDecoratedMDIFrame * frame;
extern npredictMDIClient * mdiClient;
这是头文件CLASSES.h中的Class声明：
class Signal {

}
这是SIGNAL.cpp文件中的定义：
int Signal :: undo_difference（Signal * sigptr）
{
int i，pass，pass;
double temp，sum，* dptr;
remove_display（this）; // Windows必须删除MDI子项，如果显示
if（sigptr！= NULL）{
if（sigptr-> differenced）
pass = sigptr-> differenced;
其他
返回0;
}
其他
通过=差异;
MEMTEXT（SIGNAL：undo_difference）;
dptr =（double *）REALLOC（sig，（n + pass）* sizeof（double））;
if（dptr == NULL）
返回1;
sig = dptr;
for（pass = 0; pass< pass; pass ++）{
if（sigptr！= NULL）
sum = sigptr-> leads [pass-pass-1] ;
else
sum = leads [pass-pass-1];
for（i = 0; i< n; i ++）{
temp = sig [i];
sig [i] =总和;
sum + = temp;
}
sig [n ++] = sum;
}
type = DataSignal;
known_n + =通过;
返回0;
};
在Google等上好好看看，但坚持到这里。怀疑C可能存在声明问题作为.C文件提供，但包含没有区别。
我很欣赏某些方向。

Hi
Just starting out with VS2008 C++
I'm trying to compile code from an old C++ project into a Windows Forms project. When I compile I'm getting LNK2028 errors for several of the objects of a Class. The Class is declared in a CLASSES.h file but does not seem to be recognized in the SIGNAL.cpp file. Here is the error which is typical of several:
Error 1 error LNK2028: unresolved token (0A000009) "void * __clrcall memrealloc(void *,unsigned int)" (?memrealloc@@$$FYMPAXPAXI@Z) referenced in function "public: int __clrcall Signal::undo_difference(class Signal *)" (?undo_difference@Signal@@$$FQAMHPAV1@@Z) SIGNAL.obj
Here is the "token" (I think!) declaration in the header file FUNCDEFS.h:
extern void *memrealloc ( void *ptr , unsigned int size ) ;
Code within EXTERN.h is thus:
extern TDecoratedMDIFrame *frame ; extern npredictMDIClient *mdiClient ;
Here is the Class declaration in the header file CLASSES.h:
class Signal {
public:
Signal ( char *signame , int length , double *signal ) ;
~Signal () ;
enum SignalType type ; // Optimizes display
int n ; // Length of signal
char *name ; // Its name
double *sig ; // It is here
int centered ; // Has it been centered?
double cent ; // Its center if so
int detrended ; // Has it been detrended?
double slope ; // Slope if so
double pivot ; // And pivot point
int offsetted ; // Has it been offset?
double offst ; // Offset if so
int scaled ; // Has it been scaled?
double scal ; // Its scale if so
int standardized ; // Has it been standardized?
double mean ; // Its mean if so
double std ; // And its standard deviation
int differenced ; // Has it been differenced? (Degree if so)
double leads[3] ; // First points before differencing
int seasonal ; // Has it been seasonally differenced? (Period if so)
double *sleads ; // First period points if so
int source_n ; // If CORRELATION or SPECTRUM, length of defining signal
int known_n ; // Normally n, else set by NET_PRED.CPP, ARMAPRED.CPP
int npred ; // Number of future prediction confidence intervals
double *intervals ; // This is them (2 * npred long), alloced in NP_CONF.CPP
int mult_conf ; // Normally 0, 1 if 'intervals' are multiplicative
void replace ( int n , int n_protect , double *x ) ;
void center () ;
int median_center () ;
void undo_center ( Signal *per ) ;
void detrend () ;
void undo_detrend ( Signal *per ) ;
void offset ( double val ) ;
void undo_offset ( Signal *per ) ;
void scale ( double val ) ;
void undo_scale ( Signal *per ) ;
void standardize () ;
void undo_standardize ( Signal *per ) ;
void difference ( int degree ) ;
int undo_difference ( Signal *per ) ;
int seasonal_diff ( int period ) ;
int undo_seasonal_diff ( Signal *per ) ;
void integrate ( int period ) ;
void siglog () ;
void sigexp () ;
}
Here is the definition in the SIGNAL.cpp file:
int Signal::undo_difference ( Signal *sigptr )
{
int i, pass, passes ;
double temp, sum, *dptr ;
remove_display ( this ) ; // Windows must remove MDI child if displayed
if (sigptr != NULL) {
if (sigptr->differenced)
passes = sigptr->differenced ;
else
return 0 ;
}
else
passes = differenced ;
MEMTEXT ( "SIGNAL: undo_difference" ) ;
dptr = (double *) REALLOC ( sig , (n+passes) * sizeof(double) ) ;
if (dptr == NULL)
return 1 ;
sig = dptr ;
for (pass=0 ; pass<passes ; pass++) {
if (sigptr != NULL)
sum = sigptr->leads[passes-pass-1] ;
else
sum = leads[passes-pass-1] ;
for (i=0 ; i<n ; i++) {
temp = sig[i] ;
sig[i] = sum ;
sum += temp ;
}
sig[n++] = sum ;
}
type = DataSignal ;
known_n += passes ;
return 0 ;
};
Have had a good look around on Google etc but stuck here. suspect that there might be a declaration issue with C as a .C file supplied as well but inclusion makes no difference.
I'd appreciate some direction.
Thanks

Is, by chance, your project 'managedC++'? ThisStack Overflowquestion might help: "Managed C++ unresolved token"[^].
