我正面临一个恼人的问题，一直困扰我从编程中恢复过来。 我打算开始一个个人项目，我需要使用数据库来存储某些信息，然后我决定使用SQLite，但我不喜欢C-ish API，所以我在SQLite wiki中遇到了SOCI包装器。

我去了官方的SOCI网站，阅读文档并决定试一试。 我按照文档“安装”一章中的说明进行操作，在安装完所有要求后，我编译并安装它： 

cmake -DWITH_BOOST=ON -DSOCI_TESTS=ON -DWITH_SQLITE3=ON
make
make test
sudo make install

所有测试都成功完成但是在尝试运行时（在使用g++ test.cpp -o1 -lsoci_core -lsoci_sqlite3编译之后）这样的程序如下：

TEST.CPP： 

#include "soci/soci.h"
#include "soci/sqlite3/soci-sqlite3.h"
#include <iostream>

int main()
{
    soci::session sql(soci::sqlite3, "testdb.db");

    return 0;    
}

我收到一条错误消息：“加载共享库时出错：libsoci_sqlite3.so.3.1：无法打开共享对象文件：没有这样的文件或目录。” 但是看一下安装日志，我可以清楚地看到已经安装了共享库。

我相信我找到了这个问题。 做一个： 

strace -e open ./1 2>&1 | grep soci

输出以下内容： 

open("/usr/local/lib/libsoci_core.so.3.1", O_RDONLY) = 3
open("/lib/x86_64-linux-gnu/tls/x86_64/libsoci_sqlite3.so.3.1", O_RDONLY) = -1 ENOENT (No such file or directory)

通过查看它，您可以清楚地看到它在/usr/local/lib/搜索soci_core而通常它也应该搜索soci_sqlite3 。 修复问题的快速而肮脏的黑客是在libsoci_sqlite3.so.3.1中创建了一个smylink到其中libsoci_sqlite3.so.3.1的任何其他文件夹，但我很确定有更好的方法来修复它。

在您的SOCI安装库中，库位于/ usr / local / lib64 /

以下声明应该有效：

g ++ test.cpp -o test -I / usr / local / include / soci -L / usr / local / lib64 / -lsoci_core -lsoci_sqlite3 \\
-Wl，-rpath =的/ usr /本地/ lib64下/
