Ivan, The rtl headers should but don't have #ifdef __cplusplus extern "C" #endif at the top. Therefore you have to make the extern "C" declaration yourself. I just use the example header (from examples/cpp) rtl_cpp.h and added #define <unistd.h> to it. Note: I moved the new and delete functions to another header (rtl_cpp_fun.h) so I could include rtl_cpp.h in multiple .cpp files, and include rtl_cpp_fun.h in just one (to avoid multiple copies of the function being linked together).

Hello all, The first line of my C++ realtime module is: #include <unistd.h> Which produces the following compilation errors: In file included from /usr/src/rtlinux-3.1/linux/include/linux/wait.h:14, from /usr/src/rtlinux-3.1/linux/include/linux/fs.h:12, from /usr/src/rtlinux-3.1/include/rtl_posixio.h:13, from /usr/src/rtlinux-3.1/include/posix/unistd.h:17, from rtmodule.cpp:1: /usr/src/rtlinux-3.1/linux/include/linux/list.h:35: parse error before `new' /usr/src/rtlinux-3.1/linux/include/linux/list.h: In function `void __list_add (...)': /usr/src/rtlinux-3.1/linux/include/linux/list.h:39: `next' undeclared (first use this function) /usr/src/rtlinux-3.1/linux/include/linux/list.h:39: (Each undeclared identifier is reported only once for each function it appears in.) /usr/src/rtlinux-3.1/linux/include/linux/list.h:39: parse error before `;' /usr/src/rtlinux-3.1/linux/include/linux/list.h:42: `prev' undeclared (first use this function) ... I use the attached Makefile. Do you know what's wrong?. BTW, I don't really know which C and C++ libraries I can link in realtime modules, could anybody tell me where to find info about that?.
