I'm using apr-1.6.2 apr-util-1.6.0 and pcre-8.41. All of these configure and make and make install fine.

Using httpd-2.4.27. This is my config script:

./configure --build=i686-linux --host=arm-linux --target=arm-linux \
--prefix=/usr/local \
--exec-prefix=/usr/local/src/sysroot \
--with-apr=/usr/local/src/apr-1.6.2 \
--with-apr-util=/usr/local/src/apr-util-1.6.0 \
--with-pcre=/usr/local/src/pcre-8.41/pcre-config \
ac_cv_file__dev_zero=yes \
ac_cv_func_setpgrp_word=yes \
apr_cv_process_shard_works=yes \
ac_cv_sizeof_struct_lovec=8 \
apr_cv_mutex_recursive=yes \
ap_cv_void_ptr_lt_long=8

It configures okay, but when I try to make it gives me this:

Any ideas as to what is going on here? When I 'apt-get install expat libexpat1-dev' it says that libexpat1-dev is already the newest version.

I always find it best to focus on the very first error. Fix that and retry. And repeat.

The first error I see is this: It looks like libaprutil-1.so is expecting to find symbol XML_GetErrorCode but couldn't find it. Googling reveals that symbol is in libexpat. You have to figure out how to add that library for your compiler.

You have libexpat1-dev installed for your host compiler. But you need it for your ARM compiler.

Also, the command above the error has libraries "-lrt -lcrypt -ldl -lcrypt". There should be a "-lexpat" in that list.

Try adding to your configure script.
