001、问题：checking whether to use .ctors/.dtors header and trailer... configure: error: missing __attribute__ ((constructor)) support??
[root@PC1 build]# ../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin --disable-sanity-checks --disable-werror
002、解决方法（在末尾增加了 libc_cv_ctors_header=yes ）
[root@PC1 build]# ../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin --disable-sanity-checks --disable-werror libc_cv_ctors_header=yes
。
