yzzy: gfortran --version
GNU Fortran (GCC) 4.2.3

Yes, seems to be....

Ah, yes, this is a problem -- I wasn't looking in the right place for the config.log
in Ipopt it says:

configure:5733: result: unknown
configure:5828: WARNING: unknown Fortran name-mangling scheme

I tried again with:

	 ../configure ADD_FFLAGS="-mmacosx-version-min=10.4" FFLAGS="-arch=x86_64"

but got... 


configure:4904: gfortran -o conftest -arch=x86_64 -mmacosx-version-min=10.4  conftest.f  >&5
f951: error: unrecognized command line option "-arch=x86_64"
configure:4910: $? = 1
configure: failed program was:
|       program main
|       integer i
|       end
configure:4935: WARNING: The flags FFLAGS="" do not work.  I will now just try '-O', but you might want to set FFLAGS manually.

Where and how might this manual setting be done?

Many thanks for the responses
