test for CXXLD

[Nicolas Bock]

Hi,

The C++ compiler I am using (charmc) needs an additional command line
argument during the linker stage (-language charm++). I am unsure how to
best add this argument. The generated makefiles use CXX for compilation and
CXXLD for linking, both of which are set to "charmc". How would I change
CXXLD to add a flag? Or is there a cleaner way to accomplish this?

Thanks already,

nick

One way would be to pass in the flags on the command line when you
invoke make, e.g. "make CXXLDFLAGS='-language charm++'". Ideally
autoconf would set CXXLD correctly for you but it looks like it this
hasn't been implemented for this compiler.

Thanks for the reply. I ended up using

AM_LDFLAGS = -Xcompiler "-language charm++"

For some reason CXXLDFLAGS was not added to the linker command in Makefile.

Thanks again,

Since the syntax you're using will only support one compiler anyway,
you might consider creating a shell script to do the actual configure run.

it might look something like this:

#!/bin/sh
mkdir -p build
cd build
../configure --prefix=/path/ferinst --other-arguments LDFLAGS='-Xlinker
"-languae charm++"'

Since it's not going to be portable you may as well skip the AM_
variables and go this route.

HTH,
