cvs commit: apache/src/helpers TestCompile dummy.c TestLib
jim 97/07/24 19:03:18
Modified: src Configure
src/helpers dummy.c
Added: src/helpers TestCompile
Removed: src/helpers TestLib
Log:
Configure update: We now can check if $(CC) is ANSI or not, basically
by trying to compile a small ANSI dummy program and seeing if it
fails or not. Since the core is similar to what TestLib did, we
use that but increase it's capability, thus becoming TestCompile

# Yet another Apache Configure helper script.
# This script tests certain aspects of the compilation
# process. Right now, it can perform 2 tests:
#
# ./helpers/TestCompile lib <libname>
# Which checks to see if <libname> exists on this system
#
# ./helpers/TestCompile ansi
# Which checks to see if $(CC) is ANSI
#
# It does these by creating a small mini-makefile, based on
# ../Makefile.config and trying to compile a small dummy
# program. If the compilation succeeds, we assume the test
# was successful as well.
#
# This must be run as './helpers/TestCompile' from
# the ./src directory (same directory that Configure is
# located) if you want to test it out. Configure must
# also call it as './helpers/TestCompile'
#
#
# Make sure have the right arguments
