5+
6+
CMake module to enable sanitizers for binary targets.
7+
8+
9+
## Include into your project
10+
11+
To use [FindSanitizers.cmake](cmake/FindSanitizers.cmake), simply add this repository as git submodule into your own repository
12+
```Shell
13+
mkdir externals
14+
git submodule add [email protected]:arsenm/sanitizers-cmake.git externals/sanitizers-cmake
15+
```
16+
and adding ```externals/sanitizers-cmake/cmake``` to your ```CMAKE_MODULE_PATH```
17+
```CMake
18+
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/externals/sanitizers-cmake/cmake" ${CMAKE_MODULE_PATH})
19+
```
20+
21+
If you don't use git or dislike submodules you can copy the files in [cmake directory](cmake) into your repository. *Be careful and keep updates in mind!*
22+
23+
Now you can simply run ```find_package``` in your CMake files:
24+
```CMake
25+
find_package(Sanitizers)
26+
```
27+
28+
29+
## Usage
30+
31+
You can enable the sanitizers with ``SANITIZE_ADDRESS``, ``SANITIZE_MEMORY``, ``SANITIZE_THREAD`` or ``SANITIZE_UNDEFINED`` options in your CMake configuration. You can do this by passing e.g. ``-DSANITIZE_ADDRESS=On`` on your command line or with your graphical interface.
32+
33+
If sanitizers are supported by your compiler, the specified targets will be build with sanitizer support. If your compiler has no sanitizing capabilities (I asume intel compiler doesn't) you'll get a warning but CMake will continue processing and sanitizing will simply just be ignored.
34+
35+
#### Compiler issues
36+
37+
Different compilers may be using different implementations for sanitizers. If you'll try to sanitize targets with C and Fortran code but don't use gcc & gfortran but clang & gfortran, this will cause linking problems. To avoid this, such problems will be detected and sanitizing will be disabled for these targets.
38+
39+
Even C only targets may cause problems in certain situations. Some problems have been seen with AddressSanitizer for preloading or dynamic linking. In such cases you may try the ``SANITIZE_LINK_STATIC`` to link sanitizers for gcc static.
40+
41+
42+
43+
## Build targets with sanitizer support
44+
45+
To enable sanitizer support you simply have to add ``add_sanitizers(<TARGET>)`` after defining your target. To provide a sanitizer blacklist file you can use the ``sanitizer_add_blacklist_file(<FILE>)`` function:
46+
```CMake
47+
find_package(Sanitizers)
48+
49+
sanitizer_add_blacklist_file("blacklist.txt")
50+
51+
add_executable(some_exe foo.c bar.c)
52+
add_sanitizers(some_exe)
53+
54+
add_library(some_lib foo.c bar.c)
55+
add_sanitizers(some_lib)
56+
```
57+
58+
## Run your application
59+
60+
The sanitizers check your program, while it's running. In some situations (e.g. LD_PRELOAD your target) it might be required to preload the used AddressSanitizer library first. In this case you may use the ``asan-wrapper`` script defined in ``ASan_WRAPPER`` variable to execute your application with ``${ASan_WRAPPER} myexe arg1 ...``.
