Hi Jeff,
You are actually right. In fact, stackless is not enabled by default when
it is compiled for ARM architecture. I don't know why the definition for
"__arm__" or "__arm32__" is missing.
Here is how ''STACKLESS" is defined in "Stackless/stackless.h" in
stackless-2.6.5:
---------------------------------------------------------------------------=
---
#define STACKLESS
#ifdef STACKLESS_OFF
#undef STACKLESS
/* an option to switch it off */
#elif defined(MS_WIN32) && !defined(MS_WIN64) && defined(_M_IX86)
/* MS Visual Studio on X86 */
#elif defined(_WIN64) && defined(_M_X64)
/* microsoft on 64 bit x64 thingies */
#elif defined(__GNUC__) && defined(__i386__)
/* gcc on X86 */
#elif defined(__GNUC__) && defined(__amd64__)
/* gcc on AMD64 */
#elif defined(__GNUC__) && defined(__PPC__) && defined(__linux__)
/* gcc on PowerPC */
#elif defined(__GNUC__) && defined(__ppc__) && defined(__APPLE__)
/* Apple MacOS X on PowerPC */
#elif defined(__GNUC__) && defined(sparc) && defined(sun)
/* SunOs on sparc */
#elif defined(__GNUC__) && defined(__s390__) && defined(__linux__)
/* Linux/S390 */
#elif defined(__GNUC__) && defined(__s390x__) && defined(__linux__)
/* Linux/S390 zSeries */
#elif defined(__GNUC__) && defined(__mips__) && defined(__linux__)
/* MIPS */
#else
/* no supported platform */
#undef STACKLESS
#endif
---------------------------------------------------------------------------=
---
If you take a close look at it, there is no definition for "__arm__" or
"__arm32__". So I have to manually add that definition to the header file.
Now the problem is solved. I want to thank everyone who helped!
