无法配置空间，因为它无法检测到 PROJ (libproj)

问题描述

我需要在我的系统上安装 spaceite 并且我正在从源代码安装它

我得到的源代码为：wget https://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，其中最后几行是：

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，并且处于激活的虚拟环境中，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

解决方法

这里有同样的问题，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

连同：

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

./configure

.

You have selected --enable-rttopo and/or --enable-gcp

Both modules strictly depend on code released under the GPLv2+

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
