How to config cmake for strip file

Question

when I use cmake in Release mode I have the following binary:

64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linu         


        

Answer 1

Cleanest possible way is to modify CFLAGS or CXXFLAGS (depending on C or C++ code)

set(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -s")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -s")

But there is one more hack if you do not want to change your build system (figuring out exact place where to put above lines might be tricky). You may just use strip as standalone application, like:

strip -s a.out

and do this after executable is ready to release as a post-build step. I found this way cleaner, then disturbing compiler flags.

Answer 2

You can try

set_target_properties(TARGET_NAME PROPERTIES LINK_FLAGS_RELEASE -s)
