After IRC user Twingy was also trying to get emc2 running on Ubuntu Gutsy, we found that the correct line for /etc/security/limits.conf is * hard memlock 20480 (note the leading "*") After this, Twingy reports that emc2 runs for him as user on 7.10 with self-built kernel and emc2.

Re: [Emc-users] Problems Compiling/Running - Update
I have now been able to control the X axis motor from EMC2/Axis by running it as root. So the system (Kernel with RTAI and EMC2) appears functional. Does that indicate that my problem is purely a permissions problem somewhere? I did notice that I have to be logged in as root to run the RTAI kernel latency test. If I am not then the RTAI test suite deletes /dev/rtf3 and then complains that it is missing.

Re: [Emc-users] Problems Compiling/Running - Update
Another thought - does permissions need to be set on a file somewhere to
allow the shared memory to work for all users? I did:
./configure
make
make install
I didn't run make setuid. Is that still needed for a make install?

Original Message
A little bit more info:
When this function is called:
retval = rtapi_shmem_getptr(mem_id, &mem);
mem_id = 1. Upon return, mem = 0x0 and retval = 0.
So it seems the shared memory system doesn't work properly as mem should
never be set to zero. This is pretty much the limit of my debugging
abilities.

Re: [Emc-users] Problems Compiling/Running - Update
A system call trace (produced by using "strace") or a backtrace at the time of the segmentation fault (produced using "gdb") would be helpful in pinpointing the location of the problem. You can find information how to use these utilities on many pages on the internet. Jeff - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Re: [Emc-users] Problems Compiling/Running - Update
I have narrowed the problem down to this: [EMAIL PROTECTED]:~$ /usr/local/bin/halcmd help Segmentation fault [EMAIL PROTECTED]:~$ su Password: [EMAIL PROTECTED]:/home/andy# /usr/local/bin/halcmd help Use 'help ' for more details about each command Available commands: loadrt Load realtime module(s) then the rest of the help output follows. As you can see, it works for root but not for a regular user. I'm guessing there is a setup step missing. Any ideas on how to solve this? Thanks!

Re: [Emc-users] Problems Compiling/Running - Update
Jeff, Thanks - I will give that a try. I think a shared memory error was in the mix. I also need to manually create the application menu entries. /usr/local/bin/emc is obvious. Are there any other executables that users should be able to run from the menu? Once I have this set up I will publish a blog entry with every single step to get EMC2 working so others can benefit from my efforts. thanks, Andy Jeff Epler wrote: > EMC 2.1.x is unlikely to work on Ubuntu 7.10.

Re: [Emc-users] Problems Compiling/Running - Update
EMC 2.1.x is unlikely to work on Ubuntu 7.10. However, the development version has been improved in various ways for compatability with newer versions of Ubuntu. On Ubuntu 7.10 the default amount of "locked memory" for regular users is too low. You can fix that problem by adding the line hard memlock 20480 to /etc/security/limits.conf as root. (it's necessary to log out completely after making this change) However, the result of this problem is not an "insmod error", but another error about creating shared memory areas which I don't recall. In the case of insmod errors, the last few lines shown by "dmesg" are usually most useful in determining what is going on. Jeff - This SF.net email is sponsored by: Splunk Inc.

[Emc-users] Problems Compiling/Running - Update
Update - I can get EMC2 CVS HEAD to start up with no errors if I start it as root. Otherwise it fails at the insmod stage. I guess regular users don't have permission to do this. So how do I solve this problem? thanks for the help! Andy Original Message Subject: Problems Compiling/Running Date: Sun, 28 Oct 2007 19:22:20 -0700 From: Andrew Ayre <[EMAIL PROTECTED]> To: EMC List Hi! For various reasons I have chosen to build my own kernel and compile EMC2. I'm nearly there but stumbling at the last stage. I have patched a vanilla 2.6.22 kernel with RTAI. My PC boot and runs normally and I can execute all the RTAI scripts in the testsuite. I am using Ubuntu 7.10. I compiled the CVS HEAD revision of EMC2 and installed it. When I run it, after picking a configuration (Axis Sim) it segfaults. Next I tried version 2.1.7 of EMC2. This fails to compile with: /home/andy/Desktop/emc2/emc2/src/rtapi/rtai_rtapi.c:128: error: size of array ‘type name’ is negative make[2]: *** [/home/andy/Desktop/emc2/emc2/src/rtapi/rtai_rtapi.o] Error 1 make[1]: *** [_module_/home/andy/Desktop/emc2/emc2/src] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.22-realtime' make: *** [modules] Error 2 Here is the relevant section of code: static int msg_level = RTAPI_MSG_INFO; /* message printing level */ #if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,0) MODULE_PARM(msg_level, "i"); #else #include module_param(msg_level, int, S_IRUGO | S_IWUGO); <= **line 128** #endif MODULE_PARM_DESC(msg_level, "debug message level (default=3)"); Any suggestions on what I should do next? Was a bug fixed in 2.1.7 that fixed the compile problem? What information can I provide on the segfault to troubleshoot it? It seems there is a problem with the linux headers. Here is how I configured emc2: ./configure --with-realtime=/usr/realtime --with-kernel-headers=/usr/src/linux-headers-2.6.22-realtime I am using make and make install rather than the run in place option. thanks!
