I'm facing a problem on my development server (Ubuntu 16.04 hosted on
VMWARE) when trying to compile Wireshark. It was working with older
versions (2.0 for example), but now it's like the compilation will
never
end.
I installed/updated all the required packages, since version 2.6 seems
quite different.
I'm doing an strace -f -o to find out what could be wrong, but no clue.
The
strace log being too big, here is how it looks like :
1900 execve("/usr/bin/cmake", ["cmake", "-LH", "../wireshark"], [/*
22 vars */]) = 0
[cut]
thousands of lines such as :
1901 open("/proc/537/status", O_RDONLY) = -1 ENOENT (No such file or
directory)
1901 open("/proc/538/status", O_RDONLY) = -1 ENOENT (No such file or
directory)
1901 open("/proc/539/status", O_RDONLY) = -1 ENOENT (No such file or
directory)
1901 open("/proc/540/status", O_RDONLY) = -1 ENOENT (No such file or
directory)
1901 open("/proc/541/status", O_RDONLY) = -1 ENOENT (No such file or
directory)
1901 open("/proc/542/status", O_RDONLY) = -1 ENOENT (No such file or
directory)
1901 open("/proc/543/status", O_RDONLY) = -1 ENOENT (No such file or
directory)
1901 open("/proc/544/status", O_RDONLY) = -1 ENOENT (No such file or
directory)
then thousands and thousands of lines such as the following, and it
seems
it will never end :
1901 open("/proc/882/status", O_RDONLY) = 3
1901 fstat(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
1901 read(3, "Name:\tvmhgfs-fuse\nUmask:\t0000\nSt"..., 1024) = 1024
1901 read(3, "0000,00000000,00000000,00000000,"..., 1024) = 263
1901 read(3, "", 1024) = 0
1901 close(3) = 0
1901 open("/proc/965/status", O_RDONLY) = 3
1901 fstat(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
1901 read(3, "Name:\tsystemd-logind\nUmask:\t0022"..., 1024) = 1024
1901 read(3, "0000000,00000000,00000000,000000"..., 1024) = 269
1901 read(3, "", 1024) = 0
1901 close(3) = 0
1901 open("/proc/968/status", O_RDONLY) = 3
1901 fstat(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
1901 read(3, "Name:\tdbus-daemon\nUmask:\t0022\nSt"..., 1024) = 1024
1901 read(3, "00,00000000,00000000,00000000,00"..., 1024) = 283
1901 read(3, "", 1024) = 0
1901 close(3) = 0
How can I resolve this ?
Not sure, but it seems that first subprocess (1901 == 1900 + 1) makes
some strange things.
Looking on my strace output of cmake -LH ../wireshark:
6410 execve("/usr/bin/cmake", ["cmake", "-LH", "../wireshark/"],
0x7ffe72092520 /* 32 vars */) = 0
(..)
6410 clone(child_stack=NULL,
flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD,
child_tidptr=0x7f7cde41ba50) = 6411
6411 execve("/usr/bin/python", ["/usr/bin/python", "-c", "import sys;
sys.stdout.write(';'.join([str(x) for x in sys.version_info[:3]]))"],
0x7ffc7adb4958 /* 32 vars */) = 0
first execve() is /usr/bin/python -c "import sys;
sys.stdout.write(';'.join([str(x) for x in sys.version_info[:3]]))"
Is it same for you? If you run from same shell:
/usr/bin/python -c "import sys; sys.stdout.write(';'.join([str(x) for
x in sys.version_info[:3]]))"
does it hang?
Could you please attach gzip compressed strace log?
Kind Regards,
Jakub.
