今天在Centos6.5下安装erlang，过程真是一波三折，总结一下：

下载erlang源代码包，选择版本，这里以erlang R16B03为例作说明：
[plain] view plain copy
wget http://www.erlang.org/download/otp_src_R16B03.tar.gz
tar -zxf otp_src_R16B03.tar.gz
cd otp_src_R16B03
mkdir -p /home/erl
./configure —prefix=/home/erl
make && make install
ln -s /home/erl/bin/erl /usr/bin/erl

依赖组件报错信息解决C compiler configure: error: no acceptable C compiler found in $PATHSee ‘config.log’ for more details.yum install gcccurses libraryconfigure: error: No curses library functions foundconfigure: error: /bin/sh ‘/home/otp_src_R16B03/erts/configure’ failed for ertsyum install ncurses-devel

安装erlang的时候可能会出现以下警告信息，但不影响erlang使用，如果要用到以下apps，就必须装好依赖：
[plain] view plain copy

APPLICATIONS DISABLED

crypto : No usable OpenSSL found
jinterface : No Java compiler found
odbc : ODBC library - link check failed
orber : No C++ compiler found
ssh : No usable OpenSSL found
ssl : No usable OpenSSL found
*

没装依赖的话会遇到什么问题，比如像用crypto，将会提示没有这个函数
[plain] view plain copy
Eshell V5.10.4 (abort with ^G)
1> crypto:start().
** exception error: undefined function crypto:start/0
这里有个问题，如果是装openssl，不是openssl-devel的话，crypto还是无法使用。
依赖组件没装无法使用的apps解决OpenSSLcrypto、ssh、sslyum install openssl-develJava compilerjinterfaceyum install java-develODBC libraryodbcyum install unixODBC-develC++ compilerorberyum install gcc-c++
事实上，openssl-devel在erlang中还是不能满足使用的，还需要做一些改动。
[plain] view plain copy
Eshell V5.10.4 (abort with ^G)
1> crypto:start().
=ERROR REPORT==== 24-Sep-2014::15:10:46 ===
Unable to load crypto library. Failed with error:
“load_failed, Failed to load NIF library: ‘/home/erl/lib/erlang/lib/crypto-3.2/priv/lib/crypto.so: undefined symbol: EC_GROUP_new_curve_GF2m’”
OpenSSL might not be installed on this system.

erlang R16B以上版本运行crypto:start()时，提示crypto.so: undefined symbol: EC_GROUP_new_curve_GF2m，是因为新版的libssl库去除了对一些过时算法的支持，如果程序用不到，可以注释掉otp_src_R16B0x/lib/crypto/c_src/crypto.c第81行# define HAVE_EC即可。
[plain] view plain copy
Eshell V5.10.4 (abort with ^G)
1> crypto:start().
ok
2> crypto:md5(“ggg”).
<<186,36,140,152,90,206,148,134,56,128,146,29,137,0,197,63>>
3> crypto:info_lib().
[{<<”OpenSSL”>>,268439647,
<<”OpenSSL 1.0.1e-fips 11 Feb 2013”>>}]

网上还有另一种做法：修改openssl对EC的支持
[plain] view plain copy
wget http://www.openssl.org/source/openssl-1.0.1i.tar.gz
tar -zxf openssl-1.0.1i.tar.gz
cd openssl-1.0.1i
./config —prefix=/home/ssl
sed -i “s|CFLAG= |CFLAG= -fPIC |” Makefile
make && make install

编译erlang的时候要做改动：
[plain] view plain copy
./configure —with-ssl=/home/ssl/ —prefix=/home/erl

APPLICATIONS INFORMATION *
wx : wxWidgets not found, wx will NOT be usable

解决：
yum install unixODBC-devel.x86_64
yum -y install openssl-devel.x86_64
yum -y install gcc-c++.x86_64

安装wxWidgets：
wget http://sourceforge.net/projects/wxwindows/files/3.0.1/wxWidgets-3.0.1.tar.bz2/download
bzip2 -dkv wxWidgets-3.0.1.tar.bz2
-d|—decompress 　执行解压缩 -k|—keep 　bzip2在压缩或解压缩后，不删除原文件
v|—verbose 　 显示详细的信息
tar xvf wxWidgets-3.0.1.tar
mkdir -p /usr/local/wxWidgets3.0.4
./configure —with-opengl —enable-debug —enable-unicode

wxWidgets configure 问题：
错误：** Could not run GTK+ test program, checking why…
yum install gtk+extra-devel.x86_64
错误：configure: error: OpenGL libraries not available
# yum install -y mesa
# yum install -y freeglut*
make & make install
验证wxWidgets：

wx-config —version-full

3.0.1.0
