HowTo: Fix 'undefined reference to rpl_malloc'

Cross compile iperf - CSL Wiki

When using Autotools, (automake, autoconf, etc.), one common problem when cross compiling is to end up with undefined references to rpl_malloc.

There are a references to the

ac_cv_func_malloc_0_nonnull=yes

environment variable, but the easiest is to comment out the Autotools check, which causes the problem. Malloc has a long history on what it does when you malloc a size of zero, but nowadays, these issues less common than running into rpl_malloc problems, so my vote is to delete the test if it causes problems.

In configure.ac/configure.in:

# rpl_malloc problem AC_FUNC_MALLOC

# if you must check for malloc...
AC_CHECK_FUNCS([malloc])
