linux 5 x64上安装基础软件的一些错误修复
因项目需要，以下为linux as 5 上安装基础软件时一些错误修复，仅作备忘
1、安装zlib时出现错误
gcc -I. -I. -I/dbra/app/lib/ruby/lib/ruby/1.8/x86_64-linux -I. -DRUBY_EXTCONF_H="extconf.h" -I/dbra/app/lib/openssl/include -fPIC -g -O2 -c ossl_x509req.c

/usr/bin/ld: /dbra/app/lib/openssl/lib/libssl.a(s2_meth.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/dbra/app/lib/openssl/lib/libssl.a: could not read symbols: Bad value
collect2: ld 返回 1
make: *** [openssl.so] 错误 1
解决办法：重新编译openssl
引用./config -fPIC --prefix=/dbra/app/lib/openssl enable-shared
3、安装oci8错误
引用irb(main):002:0> require 'oci8'
LoadError: /oracle/app/product/10.2.0/db_1/lib/libnnz10.so: cannot restore segment prot after reloc: Permission denied - /dbra/app/lib/ruby/lib/ruby/gems/1.8/gems/ruby-oci8-1.0.2/lib/oci8lib.so

from (irb):2
[root@bflinux dbra]# gem list

解决办法：
引用[root@bflinux dbra]# vi /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
#SELINUX=enforcing
SELINUX=disable
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted
[root@bflinux ~]# setenforce 0
irb(main):001:0> require 'oci8'
=> true
其实在上面出现Permission denied时，也可以执行
#chcon -t texrel_shlib_t $ORACLE_HOME/lib/*.so
