| 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). |
