编译安装libiconv

    cd /usr/local/src

    wget

    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

    ./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");

     ^

      ke[2]: *** [progname.o] 错误 1

    ▽ake[2]: 离开目录“/usr/local/src/libiconv-1.14/srclib”

    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!
