# 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:
$ make -j -C _gnu-make/ binsubdir=ios CC="$(xcrun --sdk iphoneos --find clang) -isysroot $(xcrun --sdk iphoneos --show-sdk-path) -arch armv7 -arch armv7s -arch arm64" postbuild="codesign -s 'iPhone Developer'"
## Compiling for Android
You will have to install the Android NDK, and point the `$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
--------------------------------------------------------------------------------
If you find this library useful and decide to use it in your own projects please
