+ * linux : gcc -fPIC -shared -o libmono-profiler-sample.so sample.c `pkg-config --cflags --libs mono-2`
* mac : gcc sample.c -o mono-profiler-sample.dylib -Dmono_free=free -lz `pkg-config --cflags mono-2` -undefined suppress -flat_namespace
+ * linux with a custom prefix (e.g. --prefix=/opt/my-mono-build):
+ * 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`
*
- * Install the binary where the dynamic loader can find it. eg /usr/lib etc

+ * For a custom prefix build, <prefix>/lib would also work.
* Then run mono with:
* mono --profile=sample your_application.exe
