[Coin-discuss] Compile of dip on AIX - help required

[Ted Ralphs]

Hi Derek,

It looks to me like you're overriding some variables that are not
really intended for users. First, I would suggest setting ADDLIBS
rather than LIBS, since this is the variable intended for what you are
wanting to do. Second, I would not set CXXFLAGS manually. With gcc,
overriding this set of flags in the way you do does break the build,
so it may also with xlc. The optimization level is set automatically,
along with a number of other flags that will be overridden by your
manual setting. There is a variable OPT_CXXFLAGS for overriding just
the optimization level if you want to use that (by default, it is
already -O2 I think) and a variables ADD_CXXFLAGS for adding flags to
the ones set automatically by configure. It is suggested on the
"current issues" page here

https://projects.coin-or.org/BuildTools/wiki/current-issues

to set ADD_CXXFLAGS="-qrtti" with xlc. Just to be safe, I would also
avoid setting CFLAGS, FFLAGS, and LDFLAGS (this one should be OK, but
since you aren't setting it to anything, it seems worth not setting it
at all). The changes that Stefan's patch makes seem to already be
present in the version of Cbc that DIP's trunk is using, so I'm not
sure that will help. Give the above a try (configuring from a clean
copy) and see if it works. By the way, if you build in a subdirectory
instead of the root, it makes getting back to a pristine copy of the
code a lot easier. Just do

mkdir build
cd build
../configure --your-args

Hope this helps. Let us know how you do.

Cheers,

Ted
