[Couenne] compiling Couenne in a macos

[Pietro Belotti]

Hello Joao,

both problems, the one you fixed and the second one, seem related to 
Couenne using (and requiring for normal use, at least for now) the Ampl 
Solver Library (ASL). A ticket was issued some time ago, and fixed, that 
should provide some help:

https://projects.coin-or.org/Couenne/ticket/1

First, did you download all ThirdParty packages? In particular, did you 
access ThirdParty/ASL and run ./getASL? If not, either you download the 
ASL or, if you don't want to use it, you should reconfigure with the 
option "--without-ASL".

If you did download the ASL, then I believe it should be visible by 
Couenne and find this a bit strange, though I have never tried to compile 
Couenne on a Mac. The symbol that the linker claims unreachable, 
_L_val_ASL is included in the ASL (and so is negInfinity), therefore it 
might be a problem of re-ordering the sequence of libraries needed by 
Couenne (though it has always worked). Please let me know if you still 
have troubles. If so, please include version of Couenne and of compiler.

Please reply (and send all your future questions about Couenne) to the 
Couenne mailing list, couenne at list.coin-or.org (cc'd).

Hope this helps.

Best regards,
Pietro
