下载mapnik,我选用的是Master的版本,Master版本需要glibc2.14+的支持,这个需要注意一下。 InstallationTroubleshooting 编译安装遇到问题汇总 git clone https://github.com/mapnik/mapnik.git 安装必要的依赖 yum install boost-devel postgresql-devel proj-devel proj-epsg 扩展需要的依赖 yum install sqlite-devel libpng-devel libtiff-devel libjpeg-devel libicu-devel 编译的时候,官方需求最少要有5GB(for g++)的内存,对于小内存的用户(我当时只有2G)可能会出现内存不够而异常退出的情况,如果出现以下状况而退出的话: g++: internal compiler error: Killed (program cc1plus) 我们可以临时增加磁盘交换空间来临时解决该问题 sudo dd if=/dev/zero of=/swapfile bs=64M count=16 sudo mkswap /swapfile sudo swapon /swapfile 然后在编译完成后,在恢复到之前的状态 sudo swapoff /swapfile sudo rm /swapfile 开始编译 ./configure make make install
Harfbuzz not found $ brew install harfbuzz ... $ ./configure ... Checking for C++ library harfbuzz... no Could not find required header or shared library for harfbuzz ... Exiting... the following required dependencies were not found: - harfbuzz (HarfBuzz text shaping library | configure with HB_LIBS & HB_INCLUDES) Solution: HB_LIBS and HB_INCLUDES are directories, not cflags/ldflags, and HB_INCLUDES needs not to include the “harfbuzz” directory itself. If pkg-config says: $ pkg-config --libs --cflags harfbuzz -I/usr/local/Cellar/harfbuzz/0.9.35_1/include/harfbuzz -L/usr/local/Cellar/harfbuzz/0.9.35_1/lib -lharfbuzz what you actually need is 修改配置文件为,直接指定HB_LIBS,HB_INCLUDES $ ./configure HB_LIBS=/usr/local/Cellar/harfbuzz/0.9.35_1/lib HB_INCLUDES=/usr/local/Cellar/harfbuzz/0.9.35_1/include 简单测试 python import mapnik 如果出现类似的错误 ImportError: libmapnik.so.3.0: cannot open shared object file: No such file or directory 需要手工添加一下so的位置 vim /etc/ld.so.conf.d/mapnik-x86_64.conf 添加一行内容: /usr/local/lib 然后保存退出,同时执行一下 ldconfig 如果没有问题的话可以试一下渲染demo,会生成一些不同品质不同格式的图片demo文件 python demo/python/rundemo.py (责任编辑:IT) |
