checkHeader fails to search current directory

(This is copied from the dev@scons.tigris.org list where more details may be found. The consensus was that this was a bug. The obvious fix is to add . to CPPPATH if the delimiters are set to "" not <>, but this seems like a bit of a hack).

The CheckXXX commands fail to include . in the relevant paths; on os/x using gcc 4.0.1 this is a problem as the compile line looks something like
gcc -o .sconf_temp/conftest_1.o -c .sconf_temp/conftest_1.c
and gcc doesn't search the parent directory.

Here's an example SConstruct file. foo.h is empty; foo.c looks like:
void nowt() {}
If you remove the "."s from the Environment, the Check tests fail (run scons twice; the first time libfoo.a is built).

import os, sys

env = Environment(CPPPATH=".", LIBPATH=".")

conf = env.Configure()

hfile = "foo.h"
if not conf.CheckHeader(hfile, '""'):
    print("Failed to find/use %s" % hfile)
    sys.exit(1)

lib = "libfoo.a"
if not os.path.isfile(lib):
    Library("foo", "foo.c")
else:
    if not conf.CheckLib(lib):
        print("Failed to find/use %s" % lib)
        sys.exit(1)

Bug party triage: Config programs should be run in the top directory (as GNU configure does). Gary and Greg to discuss implementation strategy for this and other issues related to revamping platform and tool configuration.

Collect toolchain configuration issues under a single keyword

Change all toolchain issues to enhancements scheduled for future p1.

gregnoel said at 2008-11-21 16:38:28

Consolidate toolchain issues as 2.x p3.

Adjust triage of issues.
