scim-pinyin编译过程
一、下载scim-pinyin-0.5.91和scim-1.4.9源码，并放在同一路径下，方便设置路径环境变量。
二、进入scim-pinyin-0.5.91源码，执行./configure，然后make，会出现如下错误：
Q1问题1：scim.pc找不到
checking for scim >= 1.2.0... Package scim was not found in the pkg-config search path. Perhaps you should add the directory containing `scim.pc' to the PKG_CONFIG_PATH environment variable No package 'scim' found
configure: error: Library requirements (scim >= 1.2.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
A1解决方案：
将scim-1.4.9源码下的scim.pc拷贝至pinyin源码目录下，并设置环境变量export PKG_CONFIG_PATH=./
修改scim.pc文件：
1 prefix=/usr
2 exec_prefix=${prefix}
3 libdir=${exec_prefix}/lib
4 includedir=${prefix}/include
5 localedir=${prefix}/share/locale
6 datadir=${prefix}/share
7 sysconfdir=${prefix}/etc
8
9 scimdatadir=${prefix}/share/scim
10 icondir=${prefix}/share/scim/icons
11 moduledir=${exec_prefix}/lib/scim-1.0/1.4.0
12
13 scim_binary_version=1.4.0

15 Name: SCIM
16 Description: Smart Common Input Method platform
17 Version: 1.4.9
18 Requires:
19 Libs: -L${libdir} -lscim-1.0
20 Cflags: -I/home/san/Desktop/samba/inputmethod/scim/scim-1.4.9/src
Q2问题2： scim.h头文件找不到
scim_pinyin_imengine.cpp:36:18: error: scim.h: No such file or directory
A2解决方案：
20 Cflags: -I/home/san/Desktop/samba/inputmethod/scim/scim-1.4.9/src

A3解决方案：
在scim_pinyin.cpp中包含cstring头文件
30 #define Uses_C_STRING
31
32 #include <scim.h>
33 #include "scim_pinyin.h"
类似的还有scim_phrase.cpp、scim_pinyin_phrase.cpp和scim_special_table.cpp。

解决方案：
export LD_LIBRARY_PATH=/home/san/Desktop/samba/inputmethod/scim/scim-1.4.9/src/.libs/
