无法配置 spatialite，因为它无法检测 PROJ (libproj)答案

【问题标题】：Can't configure spatialite because it can't detect PROJ (libproj)无法配置 spatialite，因为它无法检测 PROJ (libproj)
【发布时间】：2021-05-17 01:03:51
【问题描述】：

我需要在我的系统上安装 spatialite，我正在从源代码安装它

我得到的源代码为：wgethttps://www.gaia-gis.it/gaia-sins/libspatialite-sources/libspatialite-5.0.1.tar.gz

（我已经安装了 PROJ）

然后我在 libspatialite-5.0.1 目录中并运行./configure

我在命令行上得到一个很长的输出，最后几行是：

checking for library containing proj_normalize_for_visualization... no

checking for library containing pj_init_plus... no

configure: error: 'libproj' is required but it doesn't seem to be installed on this system.

Here's The Complete Command Line Output if needed for reference

我使用的是 Ubuntu 20.04，并且我在一个激活的虚拟环境中，我在该环境中安装了我正在处理的项目的所有依赖项

有人可以帮我解决这个问题吗？

谢谢

同样的问题，有这条消息：

configure: error: 'libproj' is required but it doesn't seem to be installed on this system.

解决方法：

apt-get update && apt-get -y install libproj-dev

随着：

apt-get -y install build-essential pkg-config \
  libfreexl-dev  \
  libgeos-dev  \
  librttopo-dev  \
  libxml2  \
  libzip-dev  \
  libminizip-dev

./configure

.

                        IMPORTANT NOTICE
==============================================================
You have selected --enable-rttopo and/or --enable-gcp

Both modules strictly depend on code released under the GPLv2+
license, wich takes precedence over any other license.
Consequently the copy of libspatialite you are going to build
if configured this way *must* be released under the GPLv2+ license.

If you wish better preserving the initial MPL tri-license you
simply have to reconfigure by specifying the following options:
        --disable-rttopo --disable-gcp
