在Mac OS X（Lion）上编译lsyncd

Question

我在Mac OS X（Lion）上编译lsyncd时花了很多功夫，但是我的配置脚本有些卡住了，无法找到我的lua库：

calvin$ ./configure 
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables... 
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking for style of include used by make... GNU
checking dependency style of gcc... gcc3
checking whether make sets $(MAKE)... (cached) yes
checking pkg-config is at least version 0.9.0... yes
checking for LUA... no
checking for LUA... no
checking for LUA... no
checking for LUA... no
configure: error: Package requirements (lua >= 5.1.3) were not met:
No package 'lua' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LUA_CFLAGS
and LUA_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

我确实通过macports安装了lua。

calvin$ lua -v
Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio
calvin$ which lua
/opt/local/bin/lua

UPDATE

我肯定知道lua.pc文件位于：

calvin$ sudo find /opt/local -name "lua.pc"
/opt/local/lib/pkgconfig/lua.pc

因此，在我的.bashrc文件中明确指定PKG_CONFIG和PKG_CONFIG_PATH环境变量并进行采购的程度。 像这样：

export PKG_CONFIG="/opt/local/lib/pkgconfig:$PKG_CONFIG"
export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH"

我需要怎么做才能设置正确的PKG_CONFIG_PATH环境变量，以便我的配置脚本可以找到lua？

更新＃2

所以我加了

export LUA_CFLAGS="/opt/local/include"
export LUA_LIBS="/opt/local/lib"

在我的.bashrc文件中，完成此操作后，我现在可以成功运行./configure --without-inotify ，并输出以下内容：

calvin$ ./configure --without-inotify
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d

configure: creating ./config.status

config.status: config.h is unchanged

不幸的是，运行make不工作，因为它似乎lsyncd.h头文件是不能包括lua.h 。

有什么建议么？

Answer 1

解决了它

./configure --without-inotify --with-fsevents CFLAGS="-I /Users/calvin/xnu-1699.24.23/" LUA_CFLAGS="-I /opt/local/include" LUA_LIBS="/opt/local/lib/liblua.a" 

依赖项是：

• 与Mac OS X版本相对应的XNU，在我的情况下为http://www.opensource.apple.com/source/xnu/xnu-1699.24.23/
• asciidoc（我通过macports安装）
• lsyncd中有一些小语法错误，我已经向lsyncd开发人员发送了拉取请求https://github.com/axkibe/lsyncd
• 并在以下方面对Makefile进行细微更改（从配置生成Makefile之后）：

这个

doc/lsyncd.1: doc/lsyncd.1.xml
xsltproc -o $@ -nonet /etc/asciidoc/docbook-xsl/manpage.xsl $<

至

doc/lsyncd.1: doc/lsyncd.1.xml
    xsltproc -o $@ -nonet /opt/local/etc/asciidoc/docbook-xsl/manpage.xsl $<

然后跑

make

并且lsyncd应该可以成功编译。
