similar to: compiling on Solaris 7 (PR#1520)

Full_Name: Geordon Marchak Version: R-1.3.1 OS: Solaris 2.6 Submission from: (NULL) (199.67.239.91) Got the following error when compiling on Solaris 2.6 with the standard GNU gcc package (from the Sun site). BTW - linux compiles no problem (and fast too :-) # make `Makedeps' is up to date. gcc -I. -I../../src/include -I../../src/include -I/usr/local/include -DHAVE_CONFIG_H -g -O2 -c

Hi, I would like to call R's lbfgsb function from my C/C++ code by including R_ext/Applic.h and linking against libR. Currently, I am allocating memory for x (and the other input arrays for lbfgsb) in my C/C++ code via malloc/new. However, this gives a segmentation fault when executing the program. I tried to allocate x via PROTECT(x = NEW_NUMERIC(n)); x_p = NUMERIC_POINTER(x);. This compiles

Can anyone help me with lbfgsb (function for optimization)? It takes the following parameters: void lbfgsb (int n, int lmm, double *x, double *lower, double *upper, int *nbd, double *Fmin, optimfn fn, optimgr gr, int *fail, void *ex, double factr, double pgtol, int *fncount, int *grcount, int maxit, char *msg, int trace, int nREPORT); What do I put for parameter ex (11th parameter)? I looked at

Dear all, I am trying to compile R version 1.0.1 under Solaris on a SUNsparcUltra10. Note that I'm doing this in my home directory as I cannot do it as root. The configure script seems to run correctly and issues as the last few lines: ----------------------------------------------- ... R is now configured for sparc-sun-solaris2.7 Source directory: .

Hi I have a FORTRAN version of the L-BFGS-B algorithm and I was comparing it to the code in the lbfgsb.c file available at R-4.0.0.tar.gz Everithing looks the same, except for those two lines that must be printed by the prn3lb function in case of an error (lines 3559 and 3561 in lbfgsb.c): case -5: Rprintf("l(%d) > u(%d). No feasible solution", k, k); break; case -7:

I want to write a little stand-alone C program that calls R_alloc, but I get a segmentation fault: int main(int argc, char** argv){ double* d = (double *)R_alloc(2, sizeof(double)); // <- segmentation fault! return 0; } gdb reveals that sizeof(double) evaluated to 0: > R_alloc (nelem=2, eltsize=0) at memory.c:1649 so it results in the segfault later. This is how I compile my

Hello, This morning I downloaded, unzipped, and compiled the latest version of R for unix, in my HOME/APPLICATIONS directory. My current unix machine is a sparc-sun-solaris2.9, running SunOS 5.9. Here are the last few lines of the output following ./configure: R is now configured for sparc-sun-solaris2.9 Source directory: . Installation directory: /usr/local C compiler:

Dear Mr Graves, Thank you very much for your response. Nobody else from this mailing list ventured to reply to me for the two weeks since I posted my question. "nlminb" and "optim" are just optimization procedures. What I need is not just optimization, but a nonlinear CURVE FITTING procedure. If there is some way to perform nonlinear curve fitting with the

I am trying to use the R API to call optim functions (nmmin, vmmin, lbfgsb, etc.) through a C program but I couldn't find the shared library to link under the R-2.6.0 build which is compiled under Linux (REL5). main.cpp:35: undefined reference to `Rf_initEmbeddedR(int, char**)' main.cpp:41: undefined reference to `nmmin' Thanks in advance for any help. ------------------------

Hi Everyone, I have modified my version of R-1.4.1 to include choleski with pivoting (like in Splus). I thought R-core might consider including this in the next version of R, so I give below the steps required to facilitate this. 1. Copied Linpack routine "dchdc.f" into src/appl 2. Inserted line F77_SUBROUTINE(dchdc) in src/appl/ROUTINES 3. Inserted "dchdc.f" into

Hi. I just noticed the paper by Morales and Nocedal Remark on "Algorithm 778: L-BFGS-B: Fortran Subroutines for Large-Scale Bound Constrained Optimization". TOMS 2011; 38(1): 7 http://www.ece.northwestern.edu/~morales/PSfiles/acm-remark.pdf which describes a couple of improvements (speed and accuracy) to the original Netlib code which AFAICT is that still used by optim() via f2c.

Hi, I wanted to use R's lbfgsb method for minimization from C. Unfortunately, my toy examples always crashes (segmentation fault). What's wrong with it? double eval(int n, double* par, void *ex) { double result = 0; for (int i=0; i<n; ++i) { result += par[i]*par[i]; } printf("result=%.2f\n", result); return result; } void grad(int n, double *par, double *gr,

Hi, Mark et al.: Thanks, Mark. Three comments: 1. Rvmmin was one of the methods I tried after Ravi directed me to optimx. It returned NAs for essentially everything. See my email of this subject stamped 4:43 PM Central time = 21:43 UTC. 2. It would be interesting to know if the current algorithm behind optim and optimx with
