# configure-mips.sh

|
#
|
|
# Runs the emailrelay "configure" script for a size-optimised mips build
|
|
# using uclibc.
|
|
#
|
|
# The toolchain is expected to have been built by "extra/mips/toolchain.mak".
|
|
#
|
|
# Note that in order to minimise the size of the executable a lot of
|
|
# functionality is disabled using "--disable-whatever" switches,
|
|
# and the emailrelay command-line usage is altered.
|
|
#
|
|
# usage:
|
|
# configure-mips.sh [-n] [-d <toolchain-root>] [{enable|disable} ...]
|
|
# configure-mips.sh [-a|-x]
|
|
#
|
|
# eg:
|
|
#
|
|
# build the toolchain...
|
|
# $ cd ~/emailrelay-1.8/extra/mips
|
|
# $ vi toolchain.mak
|
|
# $ make -f toolchain.mak
|
|
#
|
|
# build emailrelay...
|
|
# $ mkdir -p ~/emailrelay-1.8/mips
|
|
# $ cd ~/emailrelay-1.8/mips
|
|
# $ ../extra/mips/configure-mips.sh
|
|
# $ make
|
|
#
|
|
# install...
|
|
# $ ../extra/mips/binutils/bin/mipsel-elf-linux-gnu-strip src/main/emailrelay
|
|
# $ cp src/main/emailrelay ...
|
|
# $ cp ../extra/mips/uclibc/lib/libuClibc-0.9.27.so ...

# Consider static linking if no other c++ programs are used
|
|
# ("configure --enable-static-linking" may work), but note that
|
|
# some parts of the c runtime library seem to require dynamic
|
|
# linking; "configure --disable-dns --disable-identity" may
|
|
# help with this.
|
|
#
|
|
# For a smaller c++ runtime library take a look at the script
|

# "uClibc*/extra/libstrip/libstrip".
