# "configurehere" for ampl/solvers/snopt
# Originally written by David M. Gay at Sandia National Labs, where it
# was Approved for Unclassified-Unlimited release: SAND Number 2005-7813P
# Modified for use in ampl/solvers/snopt .

## invoke ./configurehere
## (no args) to create makefile from makefile.u for compiling "snopt"
## in this directory.  Then link libsnopt.a to this directory as
## instructed by comments in "makefile" and invoke "make" to compile snopt.
## Specify CC before invoking to adjust the CC setting in makefile.
## Specify CFLAGS before invoking to adjust CFLAGS setting in the makefile.
## CFLAGS may be further adjusted by tests done below.
## If the ampl/solvers directory is not two levels above this one,
## i.e., is not ../.. then specify ASLDIR=/full/path/to/ampl/solvers
## before invoking (with "/full/path/to/ampl/solvers" adjusted suitably).
