#agcc (Android gcc wrapper script)

agcc wrapper script has been around for a long time to make it easier to cross compile ARM code for Andriod. However, a good deal of knowledge about ARM and gcc is necessary to properly configure it. In my quest to rebuild SL4A to set the PIE bit to run on Lollipop and later, I am challenged to make it work to compile Perl NDK code. So I re-invented agcc using a completely approach and it worked for me.

The approach to this version of the agcc is not to prescript by hand all the tools options. Instead, a tester project is built under NDK and the output is captured as an example. This Perl script reads the example and removes all target file depedent options such as file names, etc. and reissue those options for your target.

The committed agcc.cfg might just work for you. Here's how I created it (my record shows that I am executing under cmd.exe prompt; other OS should be similar):

cd D:\2\safe\gits\github\agcc\extract_ndk_opts
set PATH=D:\2\wk\android\android-ndk-r11c;%PATH%
set PROMPT=$P (andndk)$G
set NDK_PROJECT_PATH=D:\2\safe\gits\github\agcc\extract_ndk_opts
ndk-build -B -d NDK_APPLICATION_MK=Application.mk | grep -P 'CreateProcess.*toolchains.*arm-' > ..\agcc.cfg

Testing the result under cygwin:

agcc -c -o extract_ndk_opts_c.o extract_ndk_opts_c.c
agcc -c -o extract_ndk_opts_cpp.o extract_ndk_opts_cpp.cpp
agcc    -o extract_ndk_opts_cpp extract_ndk_opts_c.o extract_ndk_opts_cpp.o

When I have more time I will probably polish this up a bit. But you are welcome to fork or create issue. So far it does what I needed.
