Details:
I have built and installed an uptodate g++ in a local directory, and pointed
my PATH at that set of tools. The system g++ is too old (and no, I can;t
update it).
the autoconf 2.69c beta seems to ignore that and finds the g++ in /bin.
here's the PATH as printed in the config.log
PATH: /data/users/nathans/tools/bin/
PATH: /home/nathans/my/bin/
PATH: /data/users/nathans/tools/bin/
PATH: /usr/local/bin/
PATH: /bin/
PATH: /usr/bin/
PATH: /usr/local/sbin/
PATH: /usr/sbin/
PATH: /usr/facebook/ops/scripts/
PATH: /usr/facebook/scripts/
PATH: /usr/facebook/scripts/db/
Notice that has /data/users/nathans/tools/bin in there twice. the second one
is from the shell's PATH var:
devvm293:368>echo $PATH
/home/nathans/my/bin:/data/users/nathans/tools/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/usr/facebook/ops/scripts:/usr/facebook/scripts:/usr/facebook/scripts/db
the first is because the configure script is explicitly putting it there (via
a --with-tools= option)
here's what it says of g++
configure:2348: checking for g++
configure:2369: found /bin/g++
configure:2380: result: g++
configure:2407: checking for C++ compiler version
configure:2416: g++ --version >&5
g++ (GCC) 8.3.1 20191121 (Red Hat 8.3.1-5)
Here's my actual g++
devvm293:362>whence -p g++
/data/users/nathans/tools/bin/g++
devvm293:371>g++ --version
g++ (GCC) 10.1.1 20200604
I've not dug further into this. The project containing all this is
gihub.com/urnathan/joust, I attach the configure.ac and config.m4, shout if
you need more.
