-/* Link this program with libembedding_test.so.
+/* There are two options:
+
+ =====1=====
+
+ Link this program with _embedding_test.so.
E.g. with gcc:
gcc -o embedding_test embedding_test.c _embedding_cffi*.so
+
+ You must then run the executable with the right command
+ (LD_LIBRARY_PATH on Linux), otherwise it won't find the
+ _embedding_cffi*.so:
+
+ LD_LIBRARY_PATH=. ./embedding_test
+
+ There are platform-specific options to gcc to avoid needing
+ that, too. Linux:
+
+ gcc -o embedding_test embedding_test.c _embedding_cffi*.so -Wl,-rpath=.
+
+ =====2=====
+
+ Compile and link the _embedding_test.c source code together with
+ this example (e.g. with PyPy):
+
+ gcc -o embedding_test embedding_test.c _embedding_cffi.c \
+ -I/opt/pypy/include -pthread -lpypy-c
