Overview

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)

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=arm64 --api 21 --install-dir=/tmp/android-toolchain

Now you can compile the example by running:

$ make -j -C _gnu-make/ platform=android architecture=arm64 CC=/tmp/android-toolchain/bin/aarch64-linux-android-gcc CXX=/tmp/android-toolchain/bin/aarch64-linux-android-g++

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=$PWD/app.apk!/bin/android/library.so

    Hi, thanx for your library ! (I am using it for my own project yabasic)

    Found it is not working out of the box on netbsd but a simple modification helps.

    Tested for netbsd 8.0

    Thanx for merging (if you do …) !

    Build fails on macOS when not defining _DARWIN_C_SOURCE

    Sorry to both you again. While the realpath issue is solved.

    I'm trying to build my project which includes whereami towards MacOS platform now.

    Resulting into the following errors now:

     /Users/runner/work/Browser/Browser/lib/whereami/whereami.c:431:5: error: use of undeclared identifier 'Dl_info'
    Dl_info info;

    if (dladdr(WAI_RETURN_ADDRESS(), &info))

    I tried to raise the _XOPEN_SOURCE from 500 to even 700, without luck (target_compile_definitions(${LIBARY_NAME} PUBLIC _XOPEN_SOURCE=700)). I try to enable C extensions. Also without any luck...

    Do you have missing includes in the MacOS ifdef section? I'm the cmake build system for my code. Both native Linux & Windows cross-compile builds are working.

    I'm out of ideas. Thanks in advance!

  • Precompile header

    Precompile header

    Hello, I'm trying to using your library in a project, using an older version of Visual Studio 2003 (I'm stuck with this version to maintaining a legacy app which needs the compiler and linker shipped with that VS version - sad story 😭 ).

    If I set "use precompiled header" in project properties, I have this error on building whereami.c(680): fatal error C1010: unexpected end of file while looking for precompiled header directive.

    If I don't use precompiled header in project properties, I have this error whereami.c(56): fatal error C1083: Cannot open include file: 'intrin.h': No such file or directory This header is not present on Windows installation (I searched entire C drive)

    What can I do to use your library with precompiled header?

    Add __BSD_VISIBLE define

    Some projects including this as a simple file dependency might have e.g. _ANSI_SOURCE defined in the compiler args, which unsets __BSD_VISIBLE, which hides the u_int type on FreeBSD.

  • CMake support

    CMake support

    Providing a `CMakeLists.txt instead of platform specific build files would improve a couple of things:

    • Instead of one file per build system, it would only be necessary to maintain one CMakeLists.txt.
    • It would cover support for some build systems not currently supported (ninja for example).
    • Bazel recently gained support for consuming cmake files.

    I haven't done any extensive testing, but I did write a simple CMakeLists.txt for wip-cpp branch:

    project( whereami )
cmake_minimum_required( VERSION 2.8 )

add_library( ${PROJECT_NAME} STATIC whereami.c whereami.h )
set_target_properties( ${PROJECT_NAME} PROPERTIES POSITION_INDEPENDENT_CODE ON )
target_include_directories( ${PROJECT_NAME} SYSTEM PUBLIC ${CMAKE_CURRENT_SOURCE_DIR} )

add_library( ${PROJECT_NAME}-cpp STATIC whereami++.cpp whereami++.h )
set_target_properties( ${PROJECT_NAME} PROPERTIES POSITION_INDEPENDENT_CODE ON )
target_include_directories( ${PROJECT_NAME}-cpp SYSTEM PUBLIC ${CMAKE_CURRENT_SOURCE_DIR} )
target_link_libraries( ${PROJECT_NAME}-cpp ${PROJECT_NAME} )

    It is able to produce libwhereami.a and libwhereami-cpp.a and the simplest possible example worked as expected:

    #include <iostream>
#include "../src/whereami++.h"
int main(void)
{
        std::cout << whereami::getExecutablePath();
        return 0;
}

    Executable was compiled with g++ -c foo.cpp -o foo.o and linked with g++ foo.o libwhereami++.a -o foo.

    Alternatively, providing pkgconfig files would also work with cmake.

  • solaris fix

    solaris fix

    This patch fixes the Solaris support (tested on Solaris 10 and 11).

    While the existing getExecutablePath() code works fine on Solaris the getModulePath() does not work. The code assumes that the /proc/self/map file on Solaris has the same syntax as the /proc/self/maps file on Linux. This is not the case, actually the /proc/self/map is even a binary file, see: https://docs.oracle.com/cd/E19253-01/816-5174/proc-4/index.html The dladdr() based code that is already used for other platforms in whereami however works fine on Solaris too. I added another copy of it (there is already is more than one) - this maybe could be merged.

  • added aix support

    added aix support

    This patch adds support for AIX (tested with AIX 6.1, and 7).

    getExecutablePath assumes that the current working directory was not changed since the program start. To my knowledge there is no way to get the full path to the executable (except to get the inode of the executable from /proc//map, and to traverse the whole filesystem searching for the file with that inode number).

  • Return std::string / C++ implementation

    Return std::string / C++ implementation

    The current implementation works with raw pointers. How about porting this to C++ returning a std::string instead (at least as a wrapper) for easier and less error-prone usage?
