1 #include <mono/metadata/profiler.h>
4 * Bare bones profiler. Compile with:
6 * linux : gcc -fPIC -shared -o libmono-profiler-sample.so sample.c `pkg-config --cflags --libs mono-2`
7 * mac : gcc sample.c -o mono-profiler-sample.dylib -Dmono_free=free -lz `pkg-config --cflags mono-2` -undefined suppress -flat_namespace
8 * linux with a custom prefix (e.g. --prefix=/opt/my-mono-build):
9 * gcc -fPIC -shared -o libmono-profiler-sample.so sample.c `PKG_CONFIG_PATH=/opt/my-mono-build/lib/pkgconfig/ pkg-config --cflags --libs mono-2`
11 * Install the binary where the dynamic loader can find it. eg /usr/lib etc.
12 * For a custom prefix build, <prefix>/lib would also work.
14 * mono --profile=sample your_application.exe
16 * Note if you name a profiler with more than 8 characters (eg sample6789) appears to not work
