Answer 1

一对"rpl_malloc"简单的谷歌搜索找到这个问题多次提到,与解决方案的建议.问题是Autoconf配置脚本malloc由于某种原因找不到问题,并试图回归rpl_malloc.有几个建议可以解决这个问题:

1.)ac_cv_func_malloc_0_nonnull=yes在运行之前定义环境变量configure,例如通过运行configure(假设bash shell):

ac_cv_func_malloc_0_nonnull=yes ./configure <your configure options>

要么

2.)手动更改配置脚本,rpl_malloc problem AC_FUNC_MALLOC通过在其前面添加一个注释掉该行#.
