Subject Re: [users@httpd] Default APR sizes of size_t and ssize_t when cross compiling
Date Mon, 19 Mar 2007 00:04:50 GMT
Cross compilation generally won't work because of autoconf AP_RUN_
macros which test features dynamically.  dev@apr.apache.org is a good
list to discuss working around these limitations.
