ubuntu14.04装mqtt时遇到的几个错误
在github上下载的源码:
wget https://github.com/eclipse/mosquitto/archive/v1.4.14.tar.gz
编译时，遇到了几个错误，在此小记，make时
read_handle_server.c:31:25: fatal error: uuid/uuid.h: No such file or directory
# include 解决方法：apt-get install uuid-dev
make[1]: Leaving directory `/home/lxb/mosquitto-1.4.14/src'
set -e; for d in man; do make -C ${d}; done
make[1]: Entering directory `/home/lxb/mosquitto-1.4.14/man'
xsltproc mosquitto.8.xml
make[1]: xsltproc: Command not found
make[1]: *** [mosquitto.8] Error 127
make[1]: Leaving directory `/home/lxb/mosquitto-1.4.14/man'
make: *** [docs] Error 2
这里说xsltproc命令找不到: apt-get install xsltproc-dev
make[1]: Entering directory `/home/lxb/mosquitto-1.4.14/man'
xsltproc mosquitto.8.xml
warning: failed to load external entity "/usr/share/xml/docbook/stylesheet/docbook-xsl/manpages/docbook.xsl"
compilation error: file manpage.xsl line 3 element import
xsl:import : unable to load /usr/share/xml/docbook/stylesheet/docbook-xsl/manpages/docbook.xsl
compilation error: file mosquitto.8.xml line 4 element refentry

make[1]: *** [mosquitto.8] Error 5
make[1]: Leaving directory `/home/lxb/mosquitto-1.4.14/man'
make: *** [docs] Error 2
然后就是mosquitt.8错误，看错误提示，根源还是找不到docbook.xsl
安装: apt-get install docbook-xsl
make：
install -d /usr/local/share/man/man8
install -m 644 mosquitto.8 /usr/local/share/man/man8/mosquitto.8
install -d /usr/local/share/man/man5
install -m 644 mosquitto.conf.5 /usr/local/share/man/man5/mosquitto.conf.5

install -d /usr/local/share/man/man3
install -m 644 libmosquitto.3 /usr/local/share/man/man3/libmosquitto.3
make install ：
install -d /usr/local/share/man/man8
install -m 644 mosquitto.8 /usr/local/share/man/man8/mosquitto.8
install -d /usr/local/share/man/man5

install -d /usr/local/share/man/man3
install -m 644 libmosquitto.3 /usr/local/share/man/man3/libmosquitto.3
终于通过了，启动mosquitto：mosquitto -v

mosquitto -v：

新开窗口分别进行订阅和发布：
订阅：mosquitto_sub -v -t test
test hello world(发布内容后显示）发布: mosquitto_pub -t test -m “hello world”
另外还有一些错误：
【1】编译找不到openssl/ssl.h
【解决方法】——安装openssl
sudo apt-get install libssl-dev
【2】编译过程找不到ares.h
sudo apt-get install libc-ares-dev
【3】编译过程找不到uuid/uuid.h
sudo apt-get install uuid-dev
【4】使用过程中找不到libmosquitto.so.1
error while loading shared libraries: libmosquitto.so.1: cannot open shared object file: No such file or directory
【解决方法】——修改libmosquitto.so位置
创建链接
sudo ln -s /usr/local/lib/libmosquitto.so.1 /usr/lib/libmosquitto.so.1
更新动态链接库
sudo ldconfig
【5】make: g++：命令未找到
【解决方法】
安装g++编译器
sudo apt-get install g++
接下来入手mqtt.fx(mqtt客户端），以及如何安卓上使用mqtt。
本次编译参考了大佬的博客:http://blog.csdn.net/xukai871105/article/details/39252653
在此表示感谢。
