LINK : fatal error LNK1181: cannot open input file 'libclamav.lib'

Question

I am using Microsoft Visual Studio 2010, and i am working on open source Clamav, my code is given below which is generating an error

#include <stdio.h>
#include <stdlib.h>  
#include <string.h>
#include <io.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <clamav.h>


int main(int argc, char **argv)
{
int fd, ret;
unsigned long int size = 0;
unsigned int sigs = 0;
long double mb;
const char *virname;
struct cl_engine *engine;


if(argc != 2) {
printf("Usage: %s file\n", argv[0]);
return 2;
}

if((fd = open(argv[1], O_RDONLY)) == -1) {
printf("Can't open file %s\n", argv[1]);
return 2;
}

if((ret = cl_init(CL_INIT_DEFAULT)) != CL_SUCCESS) {
printf("Can't initialize libclamav: %s\n", cl_strerror(ret));
return 2;
}

if(!(engine = cl_engine_new())) {
printf("Can't create new engine\n");
return 2;
}

/* load all available databases from default directory */
if((ret = cl_load(cl_retdbdir(), engine, &sigs, CL_DB_STDOPT)) != CL_SUCCESS) {
printf("cl_load: %s\n", cl_strerror(ret));
close(fd);
    cl_engine_free(engine);
return 2;
}

printf("Loaded %u signatures.\n", sigs);

/* build engine */
if((ret = cl_engine_compile(engine)) != CL_SUCCESS) {
printf("Database initialization error: %s\n", cl_strerror(ret));;
    cl_engine_free(engine);
close(fd);
return 2;
}

/* scan file descriptor */
if((ret = cl_scandesc(fd, &virname, &size, engine, CL_SCAN_STDOPT)) == CL_VIRUS) {
printf("Virus detected: %s\n", virname);
} else {
if(ret == CL_CLEAN) {
    printf("No virus detected.\n");
} else {
    printf("Error: %s\n", cl_strerror(ret));
    cl_engine_free(engine);
    close(fd);
    return 2;
}
}
close(fd);

/* free memory */
cl_engine_free(engine);

/* calculate size of scanned data */
mb = size * (CL_COUNT_PRECISION / 1024) / 1024.0;
printf("Data scanned: %2.2Lf MB\n", mb);

return ret == CL_VIRUS ? 1 : 0;
}

the following error is generated LINK : fatal error LNK1181: cannot open input file 'libclamav.lib'

kindly guide me

Answer 1

You get an LNK1181 error in Visual Studio when the .lib or .obj files that are specified during linking are not found in the current directory, any of the directories that are specified by the LIBPATH linker option, or any of the directories that are specified in the LIB environment variable.

You may add the directory that contains libclamav.lib library file to the LIBPATH to resolve the problem (this instructions may vary a bit depending on your Visual Studio version):

1. In Solution Explorer, right-click the project, and then click Properties .
2. In the Property Pages dialog box, expand Linker , and then click General .
3. In the Additional Library Directories field, specify the path where libclamav.lib resides.

The error can also happen when the LIBPATH contains spaces. If that's the case, move the library to a path without spaces or put quotation marks around the path.

Answer 2

You can also fix it by specifying the library path in DOS "8.3" format.

To get the 8.3 form, do (at the command line):

DIR /AD /X

recursively through every level of the directories.
