Hey, sorry about that, it seems that this buildsystem problem has sneaked in despite my best efforts to test it. Here is a necessary patch to make it build as expected: --CUT-- diff --git a/src/c/printer/write_sse.d b/src/c/printer/write_sse.d index 0c8cc29..9afea5d 100644 --- a/src/c/printer/write_sse.d +++ b/src/c/printer/write_sse.d @@ -12,6 +12,8 @@ * */ +#include <ecl/config.h> + #ifdef ECL_SSE2 #include <ecl/ecl.h> #include <ecl/internal.h> --CUT-- fix is already commited in the develop branch.
