CentOS 7下编译libiconv

编译安装libiconv

cd /usr/local/src

wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz

tar xfz libiconv-1.14.tar.gz

cd libiconv-1.14

./configure --prefix=/usr/local/libiconv

make

make install

cd ..

make时遇到错误：

gcc -DHAVE_CONFIG_H -DEXEEXT=\"\" -I. -I.. -I../lib -I../intl -DDEPENDS_ON_LIBICONV=1 -DDEPENDS_ON_LIBINTL=1 -g -O2 -c allocator.c

In file included from progname.c:26:0:

./stdio.h:1010:1: 错误：'gets'未声明(不在函数内)

_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");

make[1]: *** [all] 错误 2

make[1]: 离开目录"/usr/local/src/libiconv-1.14/srclib"

make: *** [all] 错误 2

解决办法1：

编辑stdio.h文件，将 _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");字段部分内容改为如下：

• #if defined(__GLIBC__) && !defined(__UCLIBC__) && !__GLIBC_PREREQ(2, 16)

• _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");

• #endif

• #endif

解决办法2：

cd srclib/

sed -ir -e '/gets is a security/d' ./stdio.in.h

cd ../

make

重新make即可！
