加载共享库时出错,无法打开共享库文件:没有这样的文件或目录(hiredis)

标签: c gcc makefile redis hiredis

我正处于编写C程序的Alpha阶段,该程序在后端使用Redis。

我尝试构建/安装hiredis(make && sudo make install)并运行测试(多数通过),但是当尝试构建example.c程序时,我收到hiredis.h无法显示的错误被发现。

使用以下命令在命令行上构建:gcc -v example.c -lhiredis -I / usr / local / include / hiredis /

我尝试过的事情:

  1. pkg-info hiredis返回0
  2. 通过(make && ./hiredis-test && sudo make)和(make clean)卸载/重新安装
  3. 在hireddis.c和hireddis.h所在的目录中构建example.c(仍然没有此类文件或目录)
  4. gcc -v example.c -lhiredis -I / usr / local / include / hiredis /(以及此方法的其他变体)

一切都没有运气。

我猜我没有为gcc正确链接程序,但是文档中没有任何构建示例。

我在做什么让我不能使用hiredis构建此代码(或任何代码)?

确切的输出是...

哪个产生a.out。尝试运行该程序时。我收到以下错误。

./a.out: error while loading shared libraries: libhiredis.so.0.13: cannot open shared object file: No such file or directory

3 个答案:

答案 0 :(得分:1)

由于产生了a.out文件,这意味着它已正确编译和链接。当您运行a.out时,错误消息libhiredis.so.0.13: cannot open shared object file: No such file or directory表示该库不在您的库搜索路径中。

再次检查libhiredis.so.0.13是否已安装到标准lib目录(/ lib64,/ usr / lib64,/ usr / local / lib64),或将包含该目录的目录添加到LD_LIBRARY_PATH。 >

答案 1 :(得分:1)

问题在于libhiredis不在ldconfig路径中。尽管构建过程是正确的,但它将所有内容都复制到了正确的目录ldconfig中,而不知道其位置。

您可以使用ldconfig -p查看当前知道的所有库ldconfig。

您可以使用以下方式将路径添加到ldconfig中:

sudo echo "/usr/local/lib" > /etc/ld.so.conf.d/local.conf

sudo ldconfig

答案 2 :(得分:-1)

可以使用以下命令安装缺少的库

sudo apt install libssh-4
