已编译的libgphoto2和gphoto2，但gphoto2显示较旧的libgphoto2

Question

我按照基本说明(这个参考给出了如何处理缺少的库：https://sourceforge.net/p/gphoto/mailman/message/33367636/)在Raspberry Pi上编译了最新的libgphoto2和gphoto2，但当我尝试查看安装的内容(gphoto2 -v)时，我得到了以下结果：

This version of gphoto2 is using the following software versions and options:
gphoto2         2.5.23         gcc, popt(m), no exif, no cdk, no aa, no jpeg, no readline
libgphoto2      2.5.12         all camlibs, gcc, ltdl, EXIF
libgphoto2_port 0.12.0         gcc, ltdl, USB, serial without locking

./configure和make命令工作正常。当我执行'sudo make install‘时，脚本继续执行(带有一些重新链接的警告)，但没有错误。

下面是“sudo make install”的末尾。这可能是什么原因造成的？我不应该看到libgphoto2的2.5.25吗？

我在新的Pi OS上也遇到了同样的问题。

解决方案分为两个步骤。

1. 设置PKG_CONFIG_PATH系统变量

导出PKG_CONFIG_PATH=${libdir}/pkgconfig

1. 将pi特定的--libdir选项添加到./configure

./configure --prefix=/usr --libdir=/usr/lib/arm-linux-gnueabih
