我只是想用 enable-dmalloc 构建 PHP7
环境：
the version of PHP is 7.1.0RC5
debian 8
gcc6.2
dmalloc 5.5.2
使用了这个命令：
./configure --prefix=/usr/local/php/70 --with-config-file-path=/usr/local/lib/php/70/etc --enable-fpm --with-fpm-user=www-data --with-fpm-group=www-data --with-apxs2=/usr/local/httpd/2.4/bin/apxs --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pgsql=/usr/local/PostgreSQL/9.5 --with-pdo-mysql=/usr/local/mysql --with-pdo-pgsql=/usr/local/PostgreSQL/ --enable-ftp --enable-zip --with-bz2 --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir -with-zlib --enable-bcmath --with-curl --enable-mbregex --enable-mbstring --with-mcrypt --with-gd --with-freetype-dir --enable-gd-native-ttf --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-exif --enable-debug --enable-phpdbg --enable-phpdbg-webhelper --enable-phpdbg-debug --enable-dtrace --enable-dmalloc --with-openssl --enable-shmop --enable-sysvmsg --enable-sysvsem --enable-sysvshm --with-pear --enable-maintainer-zts
make
但它失败并出现错误消息：

我在 gdft.c、gdhelper.h 和 php.h 中看到了源代码，找到了这一行：
#ifdef HAVE_DMALLOC
#include <dmalloc.h>
#endif
可能是 dmalloc 导致了这个错误，但我不知道为什么错误 msg show malloc.h，我检查了一下/usr/include，它有malloc.h两个dmalloc.h文件
我安装了包 libdmalloc 和 libdmalloc-dev 并尝试使用源代码重新安装 dmalloc 但它没有帮助
这些是什么原因造成的，我该如何处理？
