Fortran Programming Language :: Problem linking with Fortran NAG library


	Problem linking with Fortran NAG library Hi there, I'm trying to compile some code that uses the Fortran NAG library. I'm not sure how to link to the library, however. When I type g95 nhmm.f forbac.f makea.f objfun.f sumpi.f variance.f viterbi.f condsim.f beta.f cmlib.f dldp.f emalg.f I get the following link errors. I am running Debian Sarge (3.1) /tmp/ccwUzgR2.o(.text+0x19a): In function `emalg_': : undefined reference to `e04uef_' /tmp/ccwUzgR2.o(.text+0x1ae): In function `emalg_': : undefined reference to `e04uef_' /tmp/ccwUzgR2.o(.text+0x1c2): In function `emalg_': : undefined reference to `e04uef_' /tmp/ccwUzgR2.o(.text+0x1d6): In function `emalg_': : undefined reference to `e04uef_' /tmp/ccwUzgR2.o(.text+0x1ea): In function `emalg_': : undefined reference to `e04uef_' /tmp/ccwUzgR2.o(.text+0x47c): more undefined references to `e04uef_' follow /tmp/ccwUzgR2.o(.text+0xbe0): In function `stepps_': : undefined reference to `e04ucf_' Thank you, Patrick On May 6, 6:11 pm, prynh@gmail.com wrote: > Hi there, > I'm trying to compile some code that uses the Fortran NAG library.

I am running Debian Sarge (3.1) To use the NAG library, one must PURCHASE object code for the NAG library specific to a compiler and operating system. Have you done so? I don't think the NAG library is distributed for g95 or gfortran. The routine E04UCF "is designed to minimize an arbitrary smooth function subject to constraints (which may include simple bounds on the variables, linear constraints and smooth nonlinear constraints) using a sequential quadratic programming (SQP) method." There exist free Fortran codes with similar functionality, and you could try substituting one of them. > To use the NAG library, one must PURCHASE object code for the NAG > library specific to a compiler and operating system. Have you done so? Thank you for this. No I haven't purchased any code - I just tried compiling some code that I inherited "out of the box". > I don't think the NAG library is distributed for g95 or gfortran.

Do you know where I would find such codes ? I'm new to Fortran; basically I'm trying to get some code that I've been given to run...

You can search "minimiz" and "optimiz" at Alan Miller's site http://users.bigpond.net.au/amiller/ (for nonlinearly constrained optimization, cobyla may work). Some other places to look are Open Directory: Fortran: Source Code: Optimization http://dmoz.org/Computers/Programming/Languages/Fortran/Source_Code/O... NEOS Guide Optimization Tree http://www-fp.mcs.anl.gov/otc/Guide/OptWeb/index.html Netlib http://www.netlib.org/opt/ .
