Hi,
Installing the R interface on Suse 11 is not going too well for me.
(a) downloaded Algencan into /home/myhome/algencan - although could
not install according to the instructions, I successfully ran make
algencan-c PROBNAME="toyprob" as discussed previously in this forum
(b) downloaded R-interface files into /home/myhome/tango and from this
directory successfully executed (as root) the command gfortran -O4 -c -
shared -fPIC -xf77-cpp-input /home/myhome/algencan/sources/algencan/
algencan.f (c) however, could not run gcc++ -O4 -c -shared -fPIC -
Df2cFortran -I/usr/share/R/include rwrapper.c Are you able to help me
with some clarification of the instructions?
Many thanks,
Stuart

Dear Stuart, many thanks for your interest in our work.

ALGENCAN 1.0 is available as individual files from the TANGO Project
web page:

http://www.ime.usp.br/~egbirgin/tango/

ALGENCAN 1.0 has a Fortran 77 stand-alone version as well as
interfaces with AMPL, C/C++, CUTEr, Matlab, Octave, Python and R. To
install and run the Fortran 77 stand-alone version or any of the
interfaced versions, please, follow the individual Quick Start
instructions.

The beta version ALGENCAN 2.0 (current version is 2.0.2) is also
availabe as a tarball file. In this version all the interfaces are
available, unless the R and the Octave interfaces. Interfaces of
ALGENCAN 1.0 can not be used in connection with ALGENCAN 2.0. We are
currently developing the missing interfaces that will be available
soon.

I hope it helps,
Ernesto.

Hi Ernesto,
I did use Algencan 2.0.2 beta rather than 1.0 so I will try again with 1.0.
Thanks,
Stuart

Hi Ernesto,
I downloaded the Algencan 1.0 individual files but received many errors
compiling
g77 -O4 -xf77-cpp-input algencanma.f toyprob.f algencan.f -o algencanma
...using gcc instead of g77.
Also, received the same errors as mentioned before with
gcc-4.2 -O4 -c -shared -fPIC -Df2cFortran -I/usr/share/R/include rwrapper.c
... using gcc-4.3 instead of gcc-4.2.
Will it take you a long time to complete your work on the R-interface?
Thanks,
Stuart

Dear Stuart,

I do not know whether I understood your comment. algencanma.f,
algencan.f and toyprob.f are Fortran 77 programs and, as the Quick
Start suggests, they must be complied using a Fortran 77 compiler as,
for example, g77. To compile them with gcc is not an option.

I guess the R interface will be ready soon. However, you will also
need a Fortran 77 compiler to use ALGENCAN 2.0. So, my recommendation
is to pursue with the compilation of ALGENCAN 1.0.

Regards,
Ernesto.

Could you please announce here the availability of the R interface as
soon as it becomes ready?

Thanks in advance,

Thanks, Ernesto. It seems to be working fine! However, Fedora 9 users
need to replace the following line

RINC := /usr/share/R/include

with

RINC := /usr/include/R

Otherwise, one gets an error.

Hi Ernesto,
I have an error running make with algencan-2.0.4-beta.tgz
For R on Suse 11, I have modified RINC := /usr/share/R/include to RINC :=
/usr/lib/R/include/
Just checking that this this ok?
The make log is as follows.
Can you suggest what the problem might be?
Many thanks,
Stuart

Dear Stuart, please, read the README file.

a) If files R.h and Rdefines.h are located at /usr/lib/R/include/ in
your Linux installation then yes, this is the correct value for RINC.
(This explanation is in the "R interface section" of the README file.)

b) Typing only "make" you are compiling the stand-alone Fortran 77
version of ALGENCAN 2.0 instead of the R interface as you desire. The
compilation of the stand-alone Fortran 77 version of ALGENCAN 2.0 is
not being successful because the name of the Fortran 77 file with the
definition of the problem is missing. To properly compile it you
should type "make PROBNAME=toyprob" or "make algencan
PROBNAME=toyprob, where toyprob.f is a Fortran 77 file (located at $
(PROBSRC)) with the definition of the problem to be solved. (This
explanation is in the "Stand-alone Fortran 77 section" of the README
file.)

c) Finally, to compile the R interface, as you want, you must type
"make algencan-r". (This explanation is in the "R interface section"
of the README
file.)

I hope it helps.

Best regards,
Ernesto.

Hi Ernesto,
Indeed I should have read the README more fully. Algencan as a standalone
now runs fine.
However, I receive an error with part (c) of your email: make algencan-r.
"Cannot find -lg2c"
The full error is below. Your continued help is much appreciated!
Thanks,
Stuart

Dear Stuart,

Try modifying the Makefile to use -lgfortran instead of -lg2c.
Specifically, in the file /home/stuart/tango/algencan/sources/
interfaces/r/Makefile, line 15, replace -lg2c by -lgfortran. If this
change does not work, you will need to install gcc-gfortran and
libgfortran to use -lgfortran, or, alternatively, to install a package
that contains libg2c (may be gcc v3 and gcc-g77, but I am not sure).

Ernesto.

Hi Ernesto,
Your suggestion to substitute -lgfortran for -lg2c in line 15 of the
makefile worked fine.
Algencan is now operational in R, which is very nice to see!
I very much appreciate your help!
Stuart
