同样的代码code::blocks中运行正常,VSCODE中提示collect2.exe: error: ld returned 1 exit statuscollect2.exe: error: ld returned 1 exit status

一段C代码,在code::blocks中运行正常,但在VSCODE中提示C:\Users\ADMINI~1\AppData\Local\Temp\cc3JOmOu.o:test.cpp:(.text+0x93): undefined reference to `gen_Data(void*)'
collect2.exe: error: ld returned 1 exit status

代码如下:

头文件:

//kpid.h
....
typedef struct _Para
{
.....
} Para;

void gen_Data(void *p);

.c文件

//kpid.c
#include "kpid.h"
void gen_Data(void *p)
{
    Para *pa = (Para *)p;
        ......
}

main

//main.c
#include "kpid.h"

int main()
{
   Para p;
     p.menber1 = 10;    //初始化
     ....

     gen_Data(&p)
}

1、这段程序在Code::Blocks17.2 中能正常运行,可输出期望结果
2、将struct定义,gen_Data() 函数定义/实现都放到main.c文件中时(代码不变,仅放的位置移动),在vscode中也能正常运行。
3、但如上代码,定义、实现放在单独的.h,.c文件中,在main.c中包含头文件时,运行错误。提示如下。(函数名的拼写是正确的,没错)
C:\Users\ADMINI~1\AppData\Local\Temp\cc3JOmOu.o:test.cpp:(.text+0x93): undefined reference to `gen_Data(void*)'

看你什么编译器,VC++需要一个强制转换
gen_Data((void *)&p);

pkokocl
pkokocl 编译器略有差异: Code::Blicks使用的编译器是自带的 mingw32-gcc; VScode使用的编译器是mingw64-g++

QR 的问题
Problem Description QR Codes (the smallest, which is 21 pixels by 21 pixels, is shown below) are square arrays of black or white pixels (modules) which include Position Detection Patterns (the square bull's-eye patterns), Timing Patterns (the alternating black and white lines), Alignment Patterns in larger QR Codes , Format Information (the stippled pixels), Version information in larger QR Codes and Data and Error Correction Codewords (gray 8 pixel blocks). The 21-by-21 QR Code has 26 data and error correction codewords. At the lowest error correction level for this code, 19 are data codewords and 7 are error correction codewords. Data may be encoded as numeric at 3 numbers per 10 bits, as alphanumeric at 2 characters per 11 bits, as 8 bit bytes or as Kanji at 13 bits per character. Data is encoded in groups of(mode,character count,character data bits).The mode can change within the data stream. The mode is specified by a 4 bit code and the character count by a varying number of bits depending on the mode and QR Code size. For the 21-by-21 code, the character count bits are: The entire data stream ends in the termination code which may be truncated if there is not enough room. Any partially filled codeword after the termination code is filled with 0 bits. Any remaining codewords are set to 11101100 followed by 00010001 alternating. Numeric strings are encoded 3 digits at a time. If there are remaining digits, 2 digits are encoded in 7 bits or 1 digit in 4 bits. For example: 12345678 -> 123 456 78 -> 0001111011 0111001000 1001110 Prefix with mode (0001) and count (8 -> 0000001000) is (4 + 10 + 10 + 10 +7) bits: 0001 0000001000 0001111011 0111001000 1001110 Alphanumeric strings encode the haracters (<SP> represents the space character): 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ<SP>$%*+-./: as numbers from 0 to 44, then two characters are encoded in 11 bits: <first char code5> * 45 + <second char code> if the number of characters is odd, the last character is encoded in 6 bits. For example: AC-42 -> (10,12,41,4,2) -> 10*45+12=462, 41*45+4=1849, 2->00111001110 11100111001 000010 Prefix with mode and count is (4 + 9 + 11 + 11+ 6) bits: 0010 000000101 00111001110 11100111001 000010 The 8 bit binary and Kanji modes will be straightforward for the purposes of this problem. Kanji codes will just be opaque 13 bit codes; you need not decode the characters they represent, just the hexadecimal values. For example: 8 bit 0x45 0x92 0xa3 -> 01000101 10010010 10100011 Prefix with mode and count is (4 + 8 + 8 + 8 + 8) bits: 0100 00000011 01000101 10010010 10100011 Kanji 0x1ABC 07x0345 -> 1101010111100 0001101000101 Prefix with mode and count is (4 + 8 + 13 + 13) bits: 1000 00000010 1101010111100 0001101000101 To illustrate forming the 19 codeword content of a QR Code, combine the first 3 sequences above (for numeric, alphanumeric and bytes). Concatenate the bits, split into 8bit code words add the termination codeword, any fill bits and fill bytes (41 + 41 + 36 data bits + 4 bit termination code = 122 -> 6 fill bits are needed to get 16 bytes, and to fill out the 19 bytes, 3 fill bytes are needed): 0001 0000001000 0001111011 0111001000 1001110 0010 000000101 00111001110 11100111001 000010 0100 00000011 01000101 10010010 10100011 0000 000000 11101100 00010001 11101100 split into 8 bit codewords: 00010000 00100000 01111011 01110010 00100111 00010000 00010100 11100111 01110011 10010000 10010000 00001101 00010110 01001010 10001100 00000000 11101100 00010001 11101100 -> HEX 10207B72271014E77390900D164A8C0EC11EC Write a program to read 19 codewords and print the orresponding data.

The valid hexadecimal digits are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E and F. Output For each data set there is one line of output. It contains the data set number (N) followed by a single space, the number of QR decoded characters in the result, a single space and the character string corresponding to the QR Code data. In the output string, printable ASCII characters (in the range 0x20 to 0x7e) are printed as the ASCII character EXCEPT that backslash (\) is printed as \\ and pound sign (#) is printed as \#. Non-printable 8 bit data is output as \xx, where x is a hexadecimal digit (e.g. \AE). Non-printable 8 bit data is any value that is less than the ASCII value of a space (0x20) or greater than 0x76. 13 bit Kanji values are printed as #bxxx, where b is 0 or 1 and x is a hexadecimal digit (e.g. #13AC).

Count Cross 交叉的计算
Problem Description Given a MM×NN grid with different colors(black and white) on each cell, your task is to calculate the total amount of crosses of black color. We say there exists a black cross centered at the black cell (x,y) if there are four positive integer L,R,U,D that the cell(x,y-L),(x,y+R),(x-U,y),(x+D,y) are all black. Note that if two crosses have the same center but different L,R,U,D, we consider they are distinct.We use 1 to describe black. For example 00100 00100 11111 00100 00100 00000 There are 16 black crosses. The MM and NN are large, so we divide the matrix into M×N rectangle blocks.If two cells are in the same block ,their colors are same. So we can divide the sample into 4×3 blocks. Input There are at most 100 cases. In every case,there are two integers, M, N in the first line. (1≤M, N≤50) The next line contains M positive integers which are less than or equals to 50. The p-th integer describe the p-th row block's height. The next line contains N positive integers which are less than or equals to 50. The p-th integer describe the p-th colomn block's width. The following M lines each has a string which contain N digits.The q-th digit in the p-th line describe the color of the q-th colomn block in the p-th row. Output Output the answer to each case. Sample Input 4 3 2 1 2 1 2 1 2 010 111 010 000 Sample Output 16
Pusher 代码实现的思路
Problem Description PusherBoy is an online game http://www.hacker.org/push . There is an R * C grid, and there are piles of blocks on some positions. The goal is to clear the blocks by pushing into them. You should choose an empty area as the initial position of the PusherBoy. Then you can choose which direction (U for up, D for down, L for left and R for right) to push. Once the direction is chosen, the PusherBoy will walk ahead until he met a pile of blocks (Walking outside the grid is invalid). Then he remove one block from the pile (so if the pile contains only one block, it will become empty), and push the remaining pile of blocks to the next area. (If there have been some blocks in the next area, the two piles will form a new big pile.) Please note if the pusher is right up against the block, he can't remove and push it. That is, there must be a gap between the pusher and the pile. As the following figure, the pusher can go up, but cannot go down. (The cycle indicates the pusher, and the squares indicate the blocks. The nested squares indicate a pile of two blocks.) And if a whole pile is pushed outside the grid, it will be considered as cleared. Input There are several test cases in each input. The first two lines of each case contain two numbers C and R. (R,C <= 25) Then R lines follow, indicating the grid. '.' stands for an empty area, and a lowercase letter stands for a pile of blocks. ('a' for one block, 'b' for two blocks, 'c' for three, and so on.) Output Output three lines for each case. The first two lines contains two numbers x and y, indicating the initial position of the PusherBoy. (0 <= x < R, 0 <= y < C). The third line contains a moving sequence contains 'U', 'D', 'L' and 'R'. Any correct answer will be accepted. Sample Input 3 7 ... ... .b. ... ... .a. ... Sample Output 4 1 UDU

Bridging signals 信号的问题
Problem Description 'Oh no, they've done it again', cries the chief designer at the Waferland chip factory. Once more the routing designers have screwed up completely, making the signals on the chip connecting the ports of two functional blocks cross each other all over the place. At this late stage of the process, it is too expensive to redo the routing. Instead, the engineers have to bridge the signals, using the third dimension, so that no two signals cross. However, bridging is a complicated operation, and thus it is desirable to bridge as few signals as possible. The call for a computer program that finds the maximum number of signals which may be connected on the silicon surface without rossing each other, is imminent. Bearing in mind that there may be housands of signal ports at the boundary of a functional block, the problem asks quite a lot of the programmer. Are you up to the task? Figure 1. To the left: The two blocks' ports and their signal mapping (4,2,6,3,1,5). To the right: At most three signals may be routed on the silicon surface without crossing each other. The dashed signals must be bridged. A typical situation is schematically depicted in figure 1. The ports of the two functional blocks are numbered from 1 to p, from top to bottom. The signal mapping is described by a permutation of the numbers 1 to p in the form of a list of p unique numbers in the range 1 to p, in which the i:th number pecifies which port on the right side should be connected to the i:th port on the left side. Two signals cross if and only if the straight lines connecting the two ports of each pair do. Input On the first line of the input, there is a single positive integer n, telling the number of test scenarios to follow. Each test scenario begins with a line containing a single positive integer p<40000, the number of ports on the two functional blocks. Then follow p lines, describing the signal mapping: On the i:th line is the port number of the block on the right side which should be connected to the i:th port of the block on the left side. Output For each test scenario, output one line containing the maximum number of signals which may be routed on the silicon surface without crossing each other. Sample Input 4 6 4 2 6 3 1 5 10 2 3 4 5 6 7 8 9 10 1 8 8 7 6 5 4 3 2 1 9 5 8 9 2 3 1 7 4 6 Sample Output 3 9 1 4

Watch out the Animal 如何实现代码的
Problem Description There are n resting-places in the safari park. Some administrators are at the resting-places.Now we want to build a station in the park to guarantee that no animals run out of the park.Every two resting-places form a segment. If an animal runs accross a segment and thus will never be observed again, we say it is running out of the park. Lines of communication can be built between the station and a certain resting-place, but not between resting-places. Please calculate where the station should be built so that we will always know whether there are any animals running out of the park and at the same time minimize the length of the communication lines. Input The first line of input contains a positive integer, N(5<=N<=100), the number of resting-places.N lines follow. Each gives the (x,y) coordinates (in mm) of a resting-place within the park. All coordinates are integers between 0 and 10,000. Output Output consists of one number, the total distance, rounded to the nearest mm. This problem contains multiple test cases! The first line of a multiple input is an integer T, then a blank line followed by N input blocks. Each input block is in the format indicated in the problem description. There is a blank line between input blocks. The output format consists of T output blocks. There is a blank line between output blocks. Sample Input 2 8 0 0 1453 6432 0 10000 9876 1234 10000 10000 8754 2345 10000 0 2465 6843 5 2 2 0 0 2 0 0 2 1 1 Sample Output 28284 6
Repair the Wall 实现
Problem Description Long time ago , Kitty lived in a small village. The air was fresh and the scenery was very beautiful. The only thing that troubled her is the typhoon. When the typhoon came, everything is terrible. It kept blowing and raining for a long time. And what made the situation worse was that all of Kitty's walls were made of wood. One day, Kitty found that there was a crack in the wall. The shape of the crack is a rectangle with the size of 1×L (in inch). Luckly Kitty got N blocks and a saw(锯子) from her neighbors. The shape of the blocks were rectangle too, and the width of all blocks were 1 inch. So, with the help of saw, Kitty could cut down some of the blocks(of course she could use it directly without cutting) and put them in the crack, and the wall may be repaired perfectly, without any gap. Now, Kitty knew the size of each blocks, and wanted to use as fewer as possible of the blocks to repair the wall, could you help her ? Input The problem contains many test cases, please process to the end of file( EOF ). Each test case contains two lines. In the first line, there are two integers L(0<L<1000000000) and N(0<=N<600) which mentioned above. In the second line, there are N positive integers. The ith integer Ai(0<Ai<1000000000 ) means that the ith block has the size of 1×Ai (in inch). Output For each test case , print an integer which represents the minimal number of blocks are needed. If Kitty could not repair the wall, just print "impossible" instead. Sample Input 5 3 3 2 1 5 2 2 1 Sample Output 2 impossible
