1 # Google Android makefile for curl and libcurl
2 #
3 # This file can be used when building curl using the full Android source
4 # release or the NDK. Most users do not want or need to do this; please
5 # instead read the Android section in docs/INSTALL for alternate
6 # methods.
7 #
8 # Place the curl source (including this makefile) into external/curl/ in the
9 # Android source tree. Then build them with 'make curl' or just 'make libcurl'
10 # from the Android root. Tested with Android versions 1.5, 2.1-2.3
11 #
12 # Note: you must first create a curl_config.h file by running configure in the
13 # Android environment. The only way I've found to do this is tricky. Perform a
14 # normal Android build with libcurl in the source tree, providing the target
15 # "showcommands" to make. The build will eventually fail (because curl_config.h
16 # doesn't exist yet), but the compiler commands used to build curl will be
17 # shown. Now, from the external/curl/ directory, run curl's normal configure
18 # command with flags that match what Android itself uses. This will mean
19 # putting the compiler directory into the PATH, putting the -I, -isystem and
20 # -D options into CPPFLAGS, putting the -W, -m, -f, -O and -nostdlib options
21 # into CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the
22 # path to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o.
23 # Remember that the paths must be absolute since you will not be running
24 # configure from the same directory as the Android make. The normal
25 # cross-compiler options must also be set. Note that the -c, -o, -MD and
26 # similar flags must not be set.
27 #
28 # To see all the LIBS options, you'll need to do the "showcommands" trick on an
29 # executable that's already buildable and watch what flags Android uses to link
30 # it (dhcpcd is a good choice to watch). You'll also want to add -L options to
31 # LIBS that point to the out/.../obj/lib/ and out/.../obj/system/lib/
32 # directories so that additional libraries can be found and used by curl.
33 #
34 # The end result will be a configure command that looks something like this
35 # (the environment variable A is set to the Android root path which makes the
36 # command shorter):
37 #
38 # A=`realpath ../..` && \
39 # PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \
40 # ./configure --host=arm-linux CC=arm-eabi-gcc \
41 # CPPFLAGS="-I $A/system/core/include ..." \
42 # CFLAGS="-nostdlib -fno-exceptions -Wno-multichar ..." \
43 # LIBS="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/lib/gcc/arm-eabi/X\
44 # /interwork/libgcc.a ..."
45 #
46 # Finally, copy the file COPYING to NOTICE so that the curl license gets put
47 # into the right place (but see the note about this below).
