Hi Eugène,
The strace log shows that your Ubuntu 16.04 system has the "ninja" package installed, which is "a privilege escalation detection and prevention system for GNU/Linux hosts" (https://packages.ubuntu.com/xenial/admin/ninja).
It installs into /usr/sbin/ninja. Your build problem is caused by the presence of that "ninja" package on your system -- and the fact that you appear to be building wireshark as "root".
While running as "root", your PATH contains /usr/sbin, and that entry appears before /usr/bin, so instead of cmake launching the ninja build tool (/usr/bin/ninja), it launches the ninja privilege escalation detection
tool (/usr/sbin/ninja), which busily monitors your /proc directory for evidence of system intrusion... but does not build Wireshark.
1900 access("/usr/sbin/ninja", R_OK) = 0
1900 stat("/usr/sbin/ninja", {st_mode=S_IFREG|0755, st_size=22872, ...}) = 0
[...]
1901 execve("/usr/sbin/ninja", ["/usr/sbin/ninja", "--version"], [/* 22 vars */] <unfinished ...>
You should be able to resolve the issue by building Wireshark as a non-root user -- I don't think there is any need or reason to build as "root". As a regular user, your PATH should not contain /usr/sbin, and the ninja
intrusion-detection program will be ignored. cmake should then find and launch the ninja build tool correctly.
If you are not going to use the "ninja" privilege escalation detection program (for example, if it was installed by accident while you were looking for the "ninja-build" package), you can uninstall it by running "sudo
apt-get remove ninja", and that would resolve the build problem too. (Regardless, I would really advise not building as "root" unless you have a very good reason to do so!)
Cheers,

Hello,

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.
