22: # Google Android makefile for curl and libcurl
23: #
24: # This file can be used when building curl using the full Android source
25: # release or the NDK. Most users do not want or need to do this; please
26: # instead read the Android section in docs/INSTALL for alternate
27: # methods.
28: #
29: # Place the curl source (including this makefile) into external/curl/ in the
30: # Android source tree. Then build them with 'make curl' or just 'make libcurl'
31: # from the Android root. Tested with Android versions 1.5, 2.1-2.3
32: #
33: # Note: you must first create a curl_config.h file by running configure in the
34: # Android environment. The only way I've found to do this is tricky. Perform a
35: # normal Android build with libcurl in the source tree, providing the target
36: # "showcommands" to make. The build will eventually fail (because curl_config.h
37: # doesn't exist yet), but the compiler commands used to build curl will be
38: # shown. Now, from the external/curl/ directory, run curl's normal configure
39: # command with flags that match what Android itself uses. This will mean
40: # putting the compiler directory into the PATH, putting the -I, -isystem and
41: # -D options into CPPFLAGS, putting the -W, -m, -f, -O and -nostdlib options
42: # into CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the
43: # path to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o.
44: # Remember that the paths must be absolute since you will not be running
45: # configure from the same directory as the Android make. The normal
46: # cross-compiler options must also be set. Note that the -c, -o, -MD and
47: # similar flags must not be set.
48: #
49: # To see all the LIBS options, you'll need to do the "showcommands" trick on an
50: # executable that's already buildable and watch what flags Android uses to link
51: # it (dhcpcd is a good choice to watch). You'll also want to add -L options to
52: # LIBS that point to the out/.../obj/lib/ and out/.../obj/system/lib/
53: # directories so that additional libraries can be found and used by curl.
54: #
55: # The end result will be a configure command that looks something like this
56: # (the environment variable A is set to the Android root path which makes the
57: # command shorter):
58: #
59: # A=`realpath ../..` && \
60: # PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \
61: # ./configure --host=arm-linux CC=arm-eabi-gcc \
62: # CPPFLAGS="-I $A/system/core/include ..." \
63: # CFLAGS="-nostdlib -fno-exceptions -Wno-multichar ..." \
64: # LIBS="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/lib/gcc/arm-eabi/X\
65: # /interwork/libgcc.a ..."
66: #
67: # Finally, copy the file COPYING to NOTICE so that the curl license gets put
68: # into the right place (but see the note about this below).
