How to force configure script to generate release makefile

Question

While compiling some libraries (spatialite 3.0.1, geos 3.3.3 and others) I've noticed that running ./configure results in a makefile that contains lines like this

CFLAGS = -g -O2
CXXFLAGS = -g -O2

That means that debug symbol generation is enabled by default. What I want is to disable debug compiling mode without manual makefile editing. I've ran ./configure --help for both of libraries mentioned above, but I have not found any option to get desired result. I feel that the solution should be very simple, but I'm stuck on this since I'm not very familiar with building software from sources.

Answer 1

您可以将CFLAGS和CXXFLAGS以及配置脚本一起传递

./configure CFLAGS="-O2" CXXFLAGS="-O2"

Answer 2

Assuming you're talking about autoconf/automake:

Why not just keep the debugging symbols and let anybody who doesn't like them make install-strip ?
