Re: [libmicrohttpd] Cross Compiing MHD with libgnuTLS

[Evgeny Grin]

Hi David,

Instead of short form of "host" it's better to use full form. I guess 
you need --host=arm-none-linux-gnueabi so will not need to specify CC 
(it will be autodetected as well as all other tools, not only compiler).
You should point the path to GnuTLS by --with-gnutls=<path to compiled 
GnuTLS>. I suspect that you need 
--with-gnutls=/mnt/hgfs/Projects/GnuTLS/gnutls-3.6.15
Variable `LFLAGS` means nothing to configure and you don't need it 
neither something like this.

I recommend you to learn more about cross-compiling. Pay attention to 
--prefix parameter, it could help you. Also check how to use 
PKG_CONFIG_PATH. If you point it to the right directory (should be 
"${prefix}/lib/pkconfig") then you don't need to manually specify each 
library and tricky compiler and linker flags.
