ppu-ld找不到-lspe

Question

我想編譯下面的代碼，在CELL BE模擬器（mambo）上。 //hello.c

#include <stdio.h> 
#include <stdlib.h> 
#include <errno.h> 
#include <libspe.h> 
#include <sched.h> 

extern spe_program_handle_t hello_spu; 
spe_gid_t gid; 
speid_t speids[8]; 
int status[8]; 

int main(int argc, char *argv[]){ 
int i; 

printf("Hello World!\n"); 

gid = spe_create_group (SCHED_OTHER, 0, 1); 
if (gid == NULL) { 
    fprintf(stderr, "Failed spe_create_group(errno=%d)\n", errno); 
    return -1; 
} 

if (spe_group_max (gid) < 8) { 
    fprintf(stderr, "System doesn't have eight working SPEs. I'm leaving.\n"); 
    return -1; 
} 

for (i = 0; i < 8; i++) { 
    speids[i] = spe_create_thread (gid, &hello_spu,NULL, NULL, -1, 0); 
    if (speids[i] == NULL) { 
    fprintf (stderr, "FAILED: spe_create_thread(num=%d, errno=%d)\n",i, errno); 
    exit (3+i); 
    } 
} 

for (i=0; i<8; ++i){ 
    spe_wait(speids[i], &status[i], 0); 
} 

__asm__ __volatile__ ("sync" : : : "memory"); 

return 0; 

}

//生成文件

include /opt/cell/sdk/buildutils/make.footer 

編譯在此之後，它提供了以下的輸出。

$make

如何鏈接到libspe2.so libspe.so？ 請幫忙。

Answer 1

您不要將這些鏈接在一起。他們是不同的東西。如果這是您想要的庫的版本，或者您安裝安裝libspe.so庫的庫的版本，則可以更新makefile以使用-lspe2。
