InstallationTroubleshooting 編譯安裝遇到問題匯總
git clone https://github.com/mapnik/mapnik.git
安裝必要的依賴
yum install boost-devel postgresql-devel proj-devel proj-epsg
擴展需要的依賴
yum install sqlite-devel libpng-devel libtiff-devel libjpeg-devel libicu-devel
編譯的時候，官方需求最少要有5GB(for g++)的內存，對于小內存的用戶(我當時只有2G)可能會出現內存不夠而異常退出的情況，如果出現以下狀況而退出的話：
g++: internal compiler error: Killed (program cc1plus)
我們可以臨時增加磁盤交換空間來臨時解決該問題
sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile
然后在編譯完成后，在恢復到之前的狀態
sudo swapoff /swapfile
sudo rm /swapfile
開始編譯
./configure
make
make install
中間會出現錯誤如：
編譯一下harfbuzz 參照如下修改
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 修改配置文件為，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
簡單測試
如果出現類似的錯誤
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
添加一行內容： /usr/local/lib
然后保存退出，同時執行一下
如果沒有問題的話可以試一下渲染demo，會生成一些不同品質不同格式的圖片demo文件
python demo/python/rundemo.py
