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

中间会出现错误如：

编译一下harfbuzz 参照如下修改

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
