使用 tslib 和 angstrom g++ 时出现 Qt 编译错误
在上面的场景中,我收到以下编译错误。有人能告诉我为什么吗?我使用以下文档作为指导方针

In the above scenario I am getting the following compile error. Can someone tell me why? I am using the following doc as my guide line

对“rpl_malloc”进行简单的 Google 搜索可以找到许多与此问题相关的参考资料,并提供解决方案建议。问题是 Autoconf 配置脚本由于某种原因无法找到
malloc
,并尝试回退到rpl_malloc
。有几个建议可以解决此问题:1.) 在运行
configure
之前定义ac_cv_func_malloc_0_nonnull=yes
环境变量,例如通过运行 configure (假设是 bash shell) ) 为:或
2.) 手动更改配置脚本,通过在其前面添加前缀来注释掉
rpl_malloc 问题 AC_FUNC_MALLOC
行<代码>#。(参考:这篇博文等 )
A simple Google search on "rpl_malloc" finds many references to this issue, with suggestions for solutions. The problem is that the Autoconf configure script is having trouble finding
malloc
for some reason, and tries to fall back torpl_malloc
. There are a couple of suggestions to work around this:1.) Define the
ac_cv_func_malloc_0_nonnull=yes
environment variable before you runconfigure
, for instance by running configure (assuming a bash shell) as:or
2.) Manually change the configure script to comment out the
rpl_malloc problem AC_FUNC_MALLOC
line by prefixing it with a#
