CentOS 7下編譯libiconv

CentOS 7下編譯libiconv

編譯安裝libiconv

cd /usr/local/src

wgethttp://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時遇到錯誤：

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:錯誤：‘gets’未聲明(不在函數內)

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

ke[2]: *** [progname.o] 錯誤 1

▽ake[2]: 離開目錄“/usr/local/src/libiconv-1.14/srclib”

make[1]: *** [all] 錯誤 2

make[1]: 離開目錄“/usr/local/src/libiconv-1.14/srclib”

make: *** [all] 錯誤 2

解決辦法1：

編輯stdio.h文件，將 _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");字段部分內容改為如下：

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

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

• #endif

• #endif

解決辦法2：

cd srclib/

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

cd ../

make

重新make即可！
