1. Follow the Readme operation to go To the lib directory and run make to report an error:

 

 

Gcc-g-O2-D_REENTRANT-Wall-D_POSIX_PTHREAD_SEMANTICS-c-o daemon_inetd.o daemon_inetd.c

In file encoded ded from/usr/include/netinet/in. h: 24,

From/usr/include/rpc/types. h: 90,

From/usr/include/rpc. h: 38,

From unpipc. h: 115,

From daemon_inetd.c: 1:

/Usr/include/stdint. h: 49: error: duplicate 'unsigned'

/Usr/include/stdint. h: 49: error: two or more data types in declaration specifiers

/Usr/include/stdint. h: 50: Error: duplicate 'unsigned'

/Usr/include/stdint. h: 50: Error: duplicate 'shport'

/Usr/include/stdint. h: 52: Error: duplicate 'unsigned'

/Usr/include/stdint. h: 52: Error: two or more data types in Declaration specifiers

Make: *** [daemon_inetd.o] Error 1

 

Modify config. h and comment out the following three lines:

 

// # Define uint8_t unsigned char/* <sys/types. h> */

// # Define uint16_t unsigned short/* <sys/types. h> */

// # Define uint32_t unsigned int/* <sys/types. h> */

2. Link error: an error is reported when the generated libunpipc. A is linked to our C program.

Collect2: ld returned 1 exit status

 

 

Solution: add the-lrt Command Option to gcc (for details, see man mq_open)

3. GetOpt not found:

Collect2: ld returned 1 exit status

It's okay to directly change the program to getopt.
