我收到了一个.h file作为c ++程序的一部分。 我试过每个方法来链接它，但未定义的引用错误正在发生。 我在Ubuntu上使用NetBeans。
.h file包含我正在尝试使用的function。 然而，编译器无法find该function。
下面是fwlib32.h文件的一个片段，因为它太大而无法插入整个文件：
FWLIBAPI short WINAPI cnc_allclibhndl3( const char *, unsigned short, long, unsigned short * ); FWLIBAPI short WINAPI cnc_upstart3( unsigned short, short, long, long ) ; FWLIBAPI short WINAPI cnc_upstart3_f( unsigned short, short, char *, char * ) ; FWLIBAPI short WINAPI cnc_statinfo( unsigned short, ODBST * ) ; FWLIBAPI short WINAPI cnc_upload3( unsigned short, long *, char * ) ; FWLIBAPI short WINAPI cnc_upend3( unsigned short ) ; FWLIBAPI short WINAPI cnc_freelibhndl( unsigned short ) ;
这是我的程序文件：
#include "fwlib32.h" #include<pthread.h> #include<stdio.h> #include<string.h> #define BUFSIZE 1280 static unsigned short H; struct conn_data { char ip[100]; short prt; long tmo; long pnum; }; void conn(char *ipadd, short port, long tmout ) { unsigned short h; short ret; ODBST buf; ret = cnc_allclibhndl3( ipadd, port, tmout, &h ) ; if ( !ret ) { cnc_statinfo( h, &buf ) ; H=h; } else printf( "ERROR!(%d)\n", ret ) ; } short upld( long prgnum ) { unsigned short h=H; char buf[BUFSIZE+1] ; short ret ; long len; ret = cnc_upstart3( h, 0, prgnum, prgnum ) ; if ( ret ) return ( ret ) ; do { len = BUFSIZE ; ret = cnc_upload3( h, &len, buf ) ; if ( ret == EW_BUFFER ) { continue ; } if ( ret == EW_OK ) { buf[len] = '\0' ; printf( "%s", buf ) ; } if ( buf[len-1] == '%' ) { break ; } } while ( ret == EW_OK ) ; ret = cnc_upend3( h ) ; return ( ret ) ; pthread_exit(&ret); } void* start_thread(void * dat) { struct conn_data *data; data = (struct conn_data *)dat; conn(data->ip, data->prt, data->tmo); upld(data->pnum); } int main() { struct conn_data data; char ip[100]; short prt; long tmo,pnum; pthread_t thread1; int *ptr; printf("\nEnter the IP address\n"); scanf("%s",ip); strcpy(data.ip,ip); printf("\nEnter the port number\n"); scanf("%hd",&prt); data.prt=prt; printf("\nEnter the timeout period in seconds\n"); scanf("%ld",&tmo); data.tmo=tmo; printf("Enter the program number\n"); scanf("%ld",&pnum); data.pnum=pnum; pthread_create(&thread1, NULL, start_thread, (void*)&data); pthread_join(thread1, (void **) &ptr); cnc_freelibhndl( H ) ; return 0; }
这些是NetBeans中编译器窗口的内容：

我查看了其他类似的问题，试图在项目属性选项中添加库文件，或者在g ++语句中创build一个-lfwlib32选项。 他们没有任何改变。 该scheme将不会build立。 谁能帮帮我吗？
原来libfwlib32.so文件是32位系统，而我的是一个64位系统。 我会尝试在32位系统兼容性中运行它
