make: *** [sapi/fpm/php-fpm] Error 1
问题：
在lnmp编译，编译php的时候./configure之后没有问题
make的时候出现上面错误
解决：
[root@server236 php-5.3.6]# vim Makefile
找到：
EXTRA_LIBS = -lcrypt -lz -lcrypt -lrt -lmysqlclient -lmcrypt -lltdl -lldap -llber -lfreetype -lpng -lz -ljpeg -lcurl -lz -lrt -lm -ldl -lnsl -lrt -lxml2 -lz -lm -lssl -lcrypto -lcurl -lxml2 -lz -lm -lmysqlclient -lm -lrt -ldl -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt
在这个行最后面添加 -liconv
EXTRA_LIBS = -lcrypt -lz -lcrypt -lrt -lmysqlclient -lmcrypt -lltdl -lldap -llber -lfreetype -lpng -lz -ljpeg -lcurl -lz -lrt -lm -ldl -lnsl -lrt -lxml2 -lz -lm -lssl -lcrypto -lcurl -lxml2 -lz -lm -lmysqlclient -lm -lrt -ldl -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt -liconv
重新make一下
再make install
