Subject: [Rd] make check-all fails (PR#7784)
Message-ID: <20050409172136.1C551CA2F@slim.kubism.ku.dk>

Submission from: (NULL) (24.21.57.139)


I downloaded the latest R-beta tarball and did a build with the default options.
OS is Linux 2.6.11 and compiler is GCC 3.3.5. "make check-all" failed with the
following message:

make[3]: Entering directory `/home/znmeb/R-beta/tests'
running code in 'reg-tests-1.R' ...make[3]: *** [reg-tests-1.Rout] Error 1
make[3]: Leaving directory `/home/znmeb/R-beta/tests'

make[1]: *** [test-all-basics] Error 1
make[1]: Leaving directory `/home/znmeb/R-beta/tests'
make: *** [check-all] Error 2

I looked at "tests/reg-tests-1.Rout.fail"; it's 1427 lines long. The error given
is

Error: a1 == a2 is not TRUE
Execution halted

I am running on an Athlon Thunderbird with Atlas 3.6.0 installed. If necessary,
I can back Atlas out and run this again.
