# Where Am I?
|
||||
|
||||
A drop-in two files library to locate the current executable and the current
|
||||
module on the file system.
|
||||
|
||||
Supported platforms:
|
||||
|
||||
- Windows
|
||||
- Linux
|
||||
- Mac
|
||||
- iOS
|
||||
- Android
|
||||
- QNX Neutrino
|
||||
- FreeBSD
|
||||
- NetBSD
|
||||
- DragonFly BSD
|
||||
- SunOS
|
||||
|
||||
Just drop `whereami.h` and `whereami.c` into your build and get started. (see
|
||||
also [customizing compilation])
|
||||
|
||||
[customizing compilation]: #customizing-compilation
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
## Usage
|
||||
|
||||
- `wai_getExecutablePath()` returns the path of the enclosing executable
|
||||
- `wai_getModulePath()` returns the path of the enclosing module
|
||||
|
||||
Example usage:
|
||||
|
||||
- first call `int length = wai_getExecutablePath(NULL, 0, NULL);` to retrieve
|
||||
the length of the path
|
||||
- allocate the destination buffer with `path = (char*)malloc(length + 1);`
|
||||
- call `wai_getExecutablePath(path, length, &dirname_length)` again to retrieve
|
||||
the path
|
||||
- add a terminal `NUL` character with `path[length] = '\0';`
|
||||
|
||||
Here is the output of the example:
|
||||
|
||||
$ make -j -C _gnu-make
|
||||
$ cp ./bin/mac-x86_64/library.dylib /tmp/
|
||||
$ ./bin/mac-x86_64/executable --load-library=/tmp/library.dylib
|
||||
|
||||
executable path: /Users/gregory/Projects/whereami/bin/mac-x86_64/executable
|
||||
dirname: /Users/gregory/Projects/whereami/bin/mac-x86_64
|
||||
basename: executable
|
||||
module path: /Users/gregory/Projects/whereami/bin/mac-x86_64/executable
|
||||
dirname: /Users/gregory/Projects/whereami/bin/mac-x86_64
|
||||
basename: executable
|
||||
|
||||
library loaded
|
||||
executable path: /Users/gregory/Projects/whereami/bin/mac-x86_64/executable
|
||||
dirname: /Users/gregory/Projects/whereami/bin/mac-x86_64
|
||||
basename: executable
|
||||
module path: /private/tmp/library.dylib
|
||||
dirname: /private/tmp
|
||||
basename: library.dylib
|
||||
library unloaded
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
## Customizing compilation
|
||||
|
||||
You can customize the library's behavior by defining the following macros:
|
||||
|
||||
- `WAI_FUNCSPEC`
|
||||
- `WAI_PREFIX`
|
||||
- `WAI_MALLOC`
|
||||
- `WAI_REALLOC`
|
||||
- `WAI_FREE`
|
||||
|
||||
## Compiling for Windows
|
||||
|
||||
There is a Visual Studio 2015 solution in the `_win-vs14/` folder.
|
||||
|
||||
## Compiling for Linux or Mac
|
||||
|
||||
There is a GNU Make 3.81 `MakeFile` in the `_gnu-make/` folder:
|
||||
|
||||
$ make -j -C _gnu-make/
|
||||
|
||||
## Compiling for Mac
|
||||
|
||||
See above if you want to compile from command line. Otherwise there is an Xcode
|
||||
project located in the `_mac-xcode/` folder.
|
||||
|
||||
## Compiling for iOS
|
||||
|
||||
There is an Xcode project located in the `_ios-xcode/` folder.
|
||||
|
||||
If you prefer compiling from command line and deploying to a jailbroken device
|
||||
through SSH, use:
|
||||
|
||||

## Compiling for Android
|
||||
|
||||
You will have to install the Android NDK, and point the `$NDK_ROOT` environment
|
||||
variable to the NDK path: e.g. `export NDK_ROOT=/opt/android-ndk` (without a
|
||||
trailing `/` character).
|
||||
|
||||
Next, the easy way is to make a standalone Android toolchain with the following
|
||||
command:
|
||||
|
||||
$ $NDK_ROOT/build/tools/make_standalone_toolchain.py --arch=arm --install-dir=/tmp/android-toolchain
|
||||
|
||||
Now you can compile the example by running:
|
||||
|
||||
$ make -j -C _gnu-make/ libsuffix=.so binsubdir=android CC=/tmp/android-toolchain/bin/arm-linux-androideabi-gcc CXX=/tmp/android-toolchain/bin/arm-linux-androideabi-g++
|
||||
|
||||
Depending on whether you compile for an Android version that requires PIE
|
||||
executables, add `CFLAGS='-fpie' CXXFLAGS='-fpie' LDFLAGS='-pie'` accordingly.
|
||||
|
||||
Loading page aligned library straight from APKs is supported. To test, use the
|
||||
following:
|
||||
|
||||
$ zip -Z store app bin/android/library.so
|
||||
$ zipalign -v -f -p 4 ./app.zip ./app.apk
|
||||
|
||||
Then copy `bin/android/executable` and `app.apk` to your Android device and
|
||||
there launch:
|
||||
|
||||
$ ./executable --load-library=app.apk!/bin/android/library.so
|
||||
|
||||
--------------------------------------------------------------------------------

||||
