[bugzilla-daemon@xxxxxxxxxxxxx]

Bug ID	11587
Summary	CMake: Build fails under Linux due to lack of the fPiC flag
Product	Wireshark
Version	Git
Hardware	x86
OS	Gentoo
Status	UNCONFIRMED
Severity	Major
Priority	Low
Component	Build process
Assignee	bugzilla-admin@wireshark.org
Reporter	pjmarron@locoslab.com

Build Information:
None. Wireshark does not build.

After changes in CMakeList.txt to remove the use of the fPIC flag, wireshark
does not build anymore. The following error message appears after running cmake
and then make.

[  2%] Building C object wsutil/CMakeFiles/wsutil.dir/ws_mempbrk_sse42.c.o

make: *** [all] Error 2

Changing lines 349 and 571 in CMakeLists.txt to use fPIC instead of fPIE solves
the issue.

I am simply compiling the GTK version of wireshark and do not have Qt5
installed on this machine.
