Xenomai 2.4.3 ships with two versions of the Adeos I-pipe patch: one for Linux 2.6.20, the other for Linux 2.6.24. So, I would recommend using one of these two versions. Of course, you can probably adapt one of the patches to Linux 2.6.23, but that may not be obvious. Note that you may decide to apply the AT91 patch, the I-pipe patch should apply cleanly with or without the AT91 patch. --=20 Gilles From mboxrd@z Thu Jan 1 00:00:00 1970 From: "=?iso-8859-1?Q?Hans_S=F8ndergaard_(HSO)?=" Date: Thu, 1 May 2008 07:46:04 +0200 Message-ID: <2220D86D21B55040AB683933DBD97B5A263A38EC01@domain.hid> References: <2220D86D21B55040AB683933DBD97B5A263A38E8E0@domain.hid> <2ff1a98a0804290518x59f92346mfdf32c84055a10fe@domain.hid> In-Reply-To: <2ff1a98a0804290518x59f92346mfdf32c84055a10fe@domain.hid> Content-Language: en-US Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Subject: Re: [Xenomai-help] Xenomai on AT91SAM9260 List-Id: Help regarding installation and common use of Xenomai List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: Gilles Chanteperdrix Cc: "xenomai@xenomai.org" Hi, Thanks for the answer. We are now trying to install Xenomai 2.4.3 using Linux 2.6.24 on AT91SAM926= 0, but have a problem: Is it possible to disable the building of the posix skin when configuring the user space libraries for Xenomai? I have tried --disable-posix-skin, but this had no effect.

Well, I understand that it may not be important to you if you do not intend to use the posix skin, but we should try and solve this issue (which seems to be a uclibc issue). Including posix skin pthread.h instead of libc pthread.h should be no problem, since posix skin pthread.h include the libc pthread.h. The problem here is due to the fact that asm-arm/syscall.h is trying to use stderr whereas we are at the very beginning of stdio.h where stderr is not defined yet. I have to admit that I have no idea here other than defining a function in init.c which calls fprintf and to call this function instead of fprintf in asm-arm/syscall.h Philippe, any better idea ? --=20 Gilles.

And since these include files include other include files, we end up with the whole stack of xenomai includes. So, I propose the following patch which basically stop including other include files in nucleus/thread.h and nucleus/intr.h when included from user-space. The only downside of this solution is that application like cyclictest who want to use the I-pipe tracer now need to include explicitely nucleus/trace.h. --=20 Gilles. --gZBPKLq8pN Content-Type: text/plain Content-Disposition: inline; filename="xeno-fix-uclibc-includes.diff" Content-Transfer-Encoding: 7bit Index: include/nucleus/thread.h =================================================================== --- include/nucleus/thread.h (revision 3732) +++ include/nucleus/thread.h (working copy) @@ -22,8 +22,6 @@ #ifndef _XENO_NUCLEUS_THREAD_H #define _XENO_NUCLEUS_THREAD_H -#include - /*! @ingroup nucleus @defgroup nucleus_state_flags Thread state flags. @brief Bits reporting permanent or transient states of thread. @@ -130,6 +128,7 @@ #if defined(__KERNEL__) || defined(__XENO_SIM__) #include +#include #ifdef __XENO_SIM__ /* Pseudo-status (must not conflict with other bits) */ Index: include/nucleus/intr.h =================================================================== --- include/nucleus/intr.h (revision 3732) +++ include/nucleus/intr.h (working copy) @@ -22,8 +22,6 @@ #ifndef _XENO_NUCLEUS_INTR_H #define _XENO_NUCLEUS_INTR_H -#include - /* Possible return values of ISR. */ #define XN_ISR_NONE 0x1 #define XN_ISR_HANDLED 0x2 @@ -41,6 +39,7 @@ #if defined(__KERNEL__) || defined(__XENO_SIM__) +#include #include typedef struct xnintr { Index: src/skins/posix/rtdm.c =================================================================== --- src/skins/posix/rtdm.c (revision 3732) +++ src/skins/posix/rtdm.c (working copy) @@ -18,6 +18,7 @@ */ #include +#include #include #include #include Index: src/skins/posix/thread.c =================================================================== --- src/skins/posix/thread.c (revision 3732) +++ src/skins/posix/thread.c (working copy) @@ -17,6 +17,7 @@ */ #include +#include #include #include #include Index: src/skins/posix/clock.c =================================================================== --- src/skins/posix/clock.c (revision 3732) +++ src/skins/posix/clock.c (working copy) @@ -18,6 +18,7 @@ #include #include +#include #include #include /* For pthread_setcanceltype. */ #include Index: src/testsuite/cyclic/cyclictest.c =================================================================== --- src/testsuite/cyclic/cyclictest.c (revision 3732) +++ src/testsuite/cyclic/cyclictest.c (working copy) @@ -35,6 +35,7 @@ #include #include #include +#include #define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0])) --gZBPKLq8pN-- From mboxrd@z Thu Jan 1 00:00:00 1970 Message-ID: <4819F7A6.1010809@domain.hid> Date: Thu, 01 May 2008 19:02:30 +0200 From: Philippe Gerum MIME-Version: 1.0 References: <2220D86D21B55040AB683933DBD97B5A263A38E8E0@domain.hid> <2ff1a98a0804290518x59f92346mfdf32c84055a10fe@domain.hid> <2220D86D21B55040AB683933DBD97B5A263A38EC01@domain.hid> <18457.59929.12465.572294@domain.hid> In-Reply-To: <18457.59929.12465.572294@domain.hid> Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Sender: Philippe Gerum Subject: Re: [Xenomai-help] Xenomai on AT91SAM9260 Reply-To: rpm@xenomai.org List-Id: Help regarding installation and common use of Xenomai List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: Gilles Chanteperdrix Cc: "xenomai@xenomai.org" , =?ISO-8859-1?Q?=22Hans_S=F8ndergaard_=28HSO=29=22?= Gilles Chanteperdrix wrote: > Hans S=F8ndergaard (HSO) wrote: > > Hi, > >=20 > > Thanks for the answer. > > We are now trying to install Xenomai 2.4.3 using Linux 2.6.24 on AT91S= AM9260, > > but have a problem: > >=20 > > Is it possible to disable the building of the posix skin when > > configuring the user space libraries for Xenomai?
