c - ppu-ld 找不到-lspe

Question

我正在尝试在 CELL BE Simulator(mambo) 上编译下面的代码。//你好.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

编译后，它提供以下输出。

“ld”找不到 -lspe 库。“/opt/cell/sysroot/usr/lib”目录包含以下库和文件，

如何将 libspe2.so 链接到 libspe.so？请帮忙。

Answer 1

你没有将它们链接在一起。它们是不同的东西。您可以更新 makefile 以使用 -lspe2如果这是您想要的库版本，或者您安装的库版本安装了 libspe.so图书馆。
