ImportError. undefined symbol: prlimit #442

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi!
Sorry for my English.
I installed with the help of let pip. In the console do import psutil and get 
an error.

>>> import psutil
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.6/dist-packages/psutil/__init__.py", line 89, in <module>
    import psutil._pslinux as _psplatform
  File "/usr/local/lib/python2.6/dist-packages/psutil/_pslinux.py", line 21, in <module>
    import _psutil_linux
ImportError: /usr/local/lib/python2.6/dist-packages/_psutil_linux.so: undefined 
symbol: prlimit

What version of psutil are you using? What Python version?
psutil-1.1.1
Python 2.6.6

On what operating system?

OS: Debian GNU/Linux 6.0
Uname: Linux 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.41-2+deb7u2~bpo60+1 x86_64 
GNU/Linux

Mmmm. I though I fixed this in issue 438.
Are you sure this is 1.1.1 version and not 1.1.0?
Please paste the output of "grep -r prlimit /usr/include/".
Also, does "man prlimit" work (I mean is the manual available?)?

1. In the file "install.txt" output installing via pip. Install the version 
1.1.1
2. The command "grep -r prlimit /usr/include/" no output
3. The command "man prlimit" outputs "No manual entry for prlimit"

P.S.
On another server I have is OS Debian 6.0. But the kernel Linux 2.6.32-5-amd64 
# 1 SMP Mon Feb 25 02:37:03 UTC 2013 x86_64 GNU/Linux. There psutil runs great.
This server, paragraphs 2 and 3 have the same result.

Dear Giampaolo,
Please release v1.1.2.

I released a 1.1.2 bugfix-only release just now:
https://pypi.python.org/pypi/psutil#downloads
I really hope this issue won't appear again (this is the second time in 2 
releases!). =)

Hello!
I use Linux Debian 6.0, kernel 3.1.0-1.2-xen and psutil-1.1.2 (latest version).

Damn!
How is that even possible?
In _psutil_linux.c we check whether __NR_prlimit64 is defined.
Your grep into /usr/include clearly shows it isn't so it should assume 
prlimit() is NOT available.
Are you sure this is not a problem of 'old installation files still sticking 
around'?
Please retry like this:

cd psutil-1.1.2
rm -rf build dist
sudo rm -rf  /usr/local/myProjectName/python/lib/python3.3/site-packages/psutil*
python setup.py install

Hello!

First of all, I am sorry "grep -r prlimit /usr/include/" command output: 
/usr/include/asm-generic/unistd.h:#define __NR_prlimit64 261                    
/usr/include/asm-generic/unistd.h:__SYSCALL(__NR_prlimit64, sys_prlimit64)      
/usr/include/asm/unistd_x32.h:#define __NR_prlimit64 (__X32_SYSCALL_BIT + 302)  
/usr/include/asm/unistd_64.h:#define __NR_prlimit64 302                         
/usr/include/asm/unistd_32.h:#define __NR_prlimit64 340   

I have made a small research.
I type next commands: (tmp - it is an empty folder)

cd /tmp
wget http://python.org/ftp/python/3.3.0/Python-3.3.0.tar.bz2
tar jxf ./Python-3.3.0.tar.bz2
cd ./Python-3.3.0
./configure  --prefix=/tmp/python
make
make install

/tmp/python/bin/python3.3 and enter: import psutil. It is output: "ImportError: 
no module named 'psuitl'"

cd /tmp/python/lib/python3.3/site-packages, than I enter "ls" command.
this command say that this directory contains only README file.

Than I type:
cd /tmp
wget https://pypi.python.org/packages/source/p/psutil/psutil-1.1.2.tar.gz
tar -zxvf psutil-1.1.2.tar.gz
cd psutil-1.1.2
/tmp/python/bin/python3.3 setup.py install

-----------------------------------
In the file "/tmp/psutil-1.1.2/psutil/_psutil_linux.c" I changed "#define 
HAVE_PRLIMIT defined(PSUTIL_KERN_PRLIMIT) && defined(__NR_prlimit64)"
to "#define HAVE_PRLIMIT 0" and after that all work fine.

---
I have moved "#define HAVE_PRLIMIT defined(PSUTIL_KERN_PRLIMIT) && 
defined(__NR_prlimit64)" at the top of the file (_psutil_linux.c) and it is 
still equal true. There are not any "#includes" before this line.

After all of this, I have write small C programm:
#define HAVE_PRLIMIT defined(__NR_prlimit64)
int main(int argc, char *argv[]) {                                              

#if HAVE_PRLIMIT                                                                
    printf ("yes");                                                                 
#else                                                                           
    printf ("no");                                                                  
#endif                                                                          
        return 0;                                                               
}  
after compilation it is print "no", so I can not understand, why when I compile 
psuitl "defined(__NR_prlimit64)" is true (and this causes the error), but when 
I complie my test program "defined(__NR_prlimit64)" is false...

At this link: http://bugs.python.org/issue16595 I have found that "prlimit() 
needs glibc 2.13+". But command "ldd --version" return: "ldd (Debian EGLIBC 
2.11.3-4) 2.11.3", so may be this causes an error.

I'm using CentOS 6.4 in an lxc container under an Ubuntu 13.04 host.  

It seems like checking for __NR_prlimit64 must not be entirely correct, since 
I'm still getting the import error even with the above revision.

Guest glibc:
ldd (GNU libc) 2.12

You cannot have this issue on OSX because:
- it should have already been fixed
- (most importantly) it's not supposed to happen on OSX at all because the 
functionality using prlimit() is Linux only (!)
That error means psutil is not installed for some reason.
