报错信息如下

/usr/bin/ld: note: 'ber_scanf' is defined in DSO /lib64/liblber-2.4.so.2 so try adding it to the linker command line 
/lib64/liblber-2.4.so.2: could not read symbols: Invalid operation 
collect2: ld returned 1 exit status 
make: *** [sapi/cli/php] Error 1

解决办法

./configure
vim MakeFile
开头是'EXTRA_LIBS' ，结尾加上 '-llber' ；
执行 make && make test && make install
