Question

我试图编译here所示的代码：

但是我出现了链接错误。
我尝试了解决方案提及here。

但是，再次出现此错误：

  collect2：错误：ld返回1退出状态

当我尝试解决方案时，请提及here：

pkg-config --libs monetdb-mapi and pkg-config --cflags monetdb-mapi

我收到此错误：

在bzip2搜索路径中找不到包pkg-config。
  也许您应该将包含“ bzip2.pc”的目录添加到PKG_CONFIG_PATH环境变量中。
  找不到'monetdb-stream'所需的软件包'bzip2'

在搜索后，我发现Debian没有bzip2.pc。
我已经安装了以下库：

sudo apt-get install libmonetdb-client-dev
sudo apt-get install libmonetdb-stream-dev
sudo apt-get install libcurl4-openssl-dev
sudo apt-get install liblzma-dev

因此，我们将不胜感激。
我的Ubuntu版本是18.04

感谢@David C. Rankin提到的链接问题消失了：这是完整的命令：

gcc main.c -I / usr / include / monetdb -lmapi -lssl -lcrypto -lstream -lcurl -llzma -lbz2

使用C代码链接错误以连接到Monetdb
