CROSS COMPILE
|
||||
=============
|
||||
|
||||
(This section was graciously brought to us by Jim Duey, with additions by
|
||||
Dan Fandrich)
|
||||
|
||||
Download and unpack the cURL package. Version should be 7.9.1 or later.
|
||||
|
||||
'cd' to the new directory. (e.g. cd curl-7.12.3)
|
||||
|
||||
Set environment variables to point to the cross-compile toolchain and call
|
||||
configure with any options you need. Be sure and specify the '--host' and
|
||||
'--build' parameters at configuration time. The following script is an
|
||||
example of cross-compiling for the IBM 405GP PowerPC processor using the
|
||||
toolchain from MonteVista for Hardhat Linux.
|
||||
|
||||
(begin script)
|
||||
|
||||
#! /bin/sh
|
||||
|
||||
export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin
|
||||
export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include"
|
||||
export AR=ppc_405-ar
|
||||
export AS=ppc_405-as
|
||||
export LD=ppc_405-ld
|
||||
export RANLIB=ppc_405-ranlib
|
||||
export CC=ppc_405-gcc
|
||||
export NM=ppc_405-nm
|
||||
|
||||
./configure --target=powerpc-hardhat-linux \
|
||||
--host=powerpc-hardhat-linux \
|
||||
--build=i586-pc-linux-gnu \
|
||||
--prefix=/opt/hardhat/devkit/ppc/405/target/usr/local \
|
||||
--exec-prefix=/usr/local
|
||||
|
||||
(end script)
|
||||
|
||||
You may also need to provide a parameter like '--with-random=/dev/urandom'
|
||||
to configure as it cannot detect the presence of a random number
|
||||
generating device for a target system. The '--prefix' parameter
|
||||
specifies where cURL will be installed. If 'configure' completes
|
||||
successfully, do 'make' and 'make install' as usual.
|
||||
|
||||
In some cases, you may be able to simplify the above commands to as
|
||||
little as:
|
||||
|
||||
./configure --host=ARCH-OS
|
||||
|
||||
There are a number of configure options that can be used to reduce the
|
||||
size of libcurl for embedded applications where binary size is an
|
||||
important factor. First, be sure to set the CFLAGS environment variable
|
||||
when configuring with any compiler optimization flags to reduce the
|
||||
size of the binary. For gcc, this would mean at minimum:
|
||||
|
||||
env CFLAGS='-Os' ./configure ...
|
||||
|
||||
Be sure to specify as many --disable- and --without- flags on the configure
|
||||
command-line as you can to disable all the libcurl features that you
|
||||
know your application is not going to need. Besides specifying the
|
||||
--disable-PROTOCOL flags for all the types of URLs your application
|
||||
will not use, here are some other flags that can reduce the size of the
|
||||
library:
|
||||
|
||||
--disable-ares (disables support for the ARES DNS library)
|
||||
--disable-cookies (disables support for HTTP cookies)
|
||||
--disable-crypto-auth (disables HTTP cryptographic authentication)
|
||||
--disable-ipv6 (disables support for IPv6)
|
||||
--disable-verbose (eliminates debugging strings and error code strings)
|
||||
--without-libidn (disables support for the libidn DNS library)
|
||||
--without-ssl (disables support for SSL/TLS)
|
||||
--without-zlib (disables support for on-the-fly decompression)
|
||||
|
||||
You may find that statically linking libcurl to your application will
|
||||
result in a lower total size.
