I am building Octave from source code on OS X 10.15.7
The linker is generating numerous errors:
E.g.
"bsxfun_add(intNDArray<octave_int<signed char> > const&, intNDArray<octave_int<signed char> > const&)", referenced from:
octave_value bsxfun_forward_op<intNDArray<octave_int<signed char> >, &(bsxfun_add(intNDArray<octave_int<signed char> > const&, intNDArray<octave_int<signed char> > const&))>(octave_value const&, octave_value const&) in libcorefcn.a(libcorefcn_la-bsxfun.o)

There are compiler warnings regarding DEPRECATED functions but it seems unrelated.

The mangled names in the object file and the static library appear to be slightly different from the one in compile warning:
demangled with http://demangler.com:
_octave_value bsxfun_forward_op<NDArray, &(bsxfun_add(NDArray const&, NDArray const&))>(octave_value const&, octave_value const&)
Linker error (undefined symbol):
octave_value bsxfun_forward_op<intNDArray<octave_int<signed char> >, &(bsxfun_add(intNDArray<octave_int<signed char> > const&, intNDArray<octave_int<signed char> > const&))>(octave_value const&, octave_value const&)

I already have OCaml installed on my Mac by running these commands:
$ brew install opam
$ opam init --bare -a -y
$ opam switch create cs3110-2022fa ocaml-base-compiler.4.14.0
Running any OCaml code which only uses Standard library modules works fine. Then I want to do a few things that are not covered with it, e.g reading CSV files.
$ opam install csv
Let's try to compile this code
open Printf
open Csv
let embedded_csv = "\

let fname = Filename.concat (Filename.get_temp_dir_name()) "example.csv" in

The result is:

Error: Unbound module Csv
How to tell OCaml compiler where to find Csv module path?
This seems like a wonderful place to use Dune, but going a little bit old school you can use ocamlfind to locate the package.
% cat test2.ml
open Csv
let () = print_endline "hello"
% ocamlopt -I `ocamlfind query csv` -o test2 csv.cmxa test2.ml
% ./test2
hello
%
Or alternatively:
ocamlfind ocamlopt -package csv -o test2 cvs.cmxa test2.ml

it's all
As I know, we could define function in .vimrc as below:
function Fun()
do something here
endfunction
Then we could call it like :call Fun().
For one of my system, there's only the function definition in my .vimrc, however the function is always exectued once I get into vim. Why?
Below is version of my vim:

And my .vimrc:
# cat ~/.vimrc
function Fun1()
:!ls
endfunction
Function name doesn't matter, I've changed the name as a test.
Update on July 8, 2015:
According to the answer from Ben, and since I'd like my .vimrc be compatible over multiple environments, I wrap the function definition with if has('eval')...endif as my finial solution:
if has('eval')
function! Fun1()
do something
endfunction
endif
Your vim is compiled without "eval" support. That means your Vim does not support defining functions. The opening function Fun1() command is therefore invalid, and ignored. Then the function definition is executed because those are valid commands.
You will need to install a more fully-featured Vim, or compile your own Vim, or find an alternate Vim installation on your system that has more features. "eval" comes with a NORMAL or larger feature set.
octave 3.8.2 produces this error on loading:

Both octave and fltk were compiled from source under gentoo:
x11-libs/fltk-1.3.3-r2:1 USE="opengl -cairo -debug -doc -examples -games -pdf -static-libs -threads -xft -xinerama"
sci-mathematics/octave-3.8.2:0/3.8.2 USE="X doc glpk gnuplot gui imagemagick opengl qhull qrupdate readline sparse zlib -curl -fftw -hdf5 -java -jit -postscript -static-libs"
resulting in configure switches of (for the fltk library):
./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --includedir=/usr/include/fltk --libdir=/usr/lib64/fltk --docdir=/usr/share/doc/fltk-1.3.3-r2/html --enable-largefile --enable-shared --enable-xdbe --disable-localjpeg --disable-localpng --disable-localzlib --disable-debug --disable-cairo --enable-gl --disable-threads --disable-xft --disable-xinerama
and (for octave)

If I examine libfltk_gl.so.1.3 with nm, I see that the following symbols are exported:
$ nm -D /usr/lib64/fltk/libfltk_gl.so.1.3
U XCreateColormap
U XGetUtf8FontAndGlyph
w _ITM_deregisterTMCloneTable
w _ITM_registerTMCloneTable
w _Jv_RegisterClasses
U _Z10fl_measurePKcRiS1_i
000000000000e170 T _Z10gl_descentv
000000000000e590 T _Z10gl_measurePKcRiS1_
... <snip>
According to nm manual, the U designates that the symbol is global (external) but unknown. My question is whether this unknown symbol status is the origin of the error reported from octave, suggesting that the problem lies with how fltk was compiled, or whether the octave compilation is somehow at fault.
Edit: Solved by enabling Xft support: Please see comments below, and I thank Andy again for his help.
XGetUtf8FontAndGlyph should be in libfltk.so.1.3.
nm -D /usr/lib/x86_64-linux-gnu/libfltk.so.1.3 |grep XGetU
00000000000c2fc0 T XGetUtf8FontAndGlyph
It's very likely that this is a problem with your configure flags for fltk and not GNU Octave. Just try it with the default settings first.
You can test if the UTF8 stuff with OpenGL is okay with the "cube" test. Just digg into the fltk-source dir tests:
cd fltk-1.3.3/test
make cube && ./cube
Does the text in the lower left of the GL window show up?
Had a similar problem. Was getting the following error while trying to run octave (undefined symbol: _ZN18Fl_XFont_On_Demand5valueEv):
bash-4.3$ octave
error: /usr/local/lib/octave/4.0.2/oct/i686-pc-linux-gnu/PKG_ADD: /usr/local/lib/octave/4.0.2/oct/i686-pc-linux-gnu/__init_fltk__.oct: failed to load: /usr/lib/libfltk_gl.so.1.3: undefined symbol: _ZN18Fl_XFont_On_Demand5valueEv
error: called from
/usr/local/lib/octave/4.0.2/oct/i686-pc-linux-gnu/PKG_ADD at line 3 column 1
Command nm -D /usr/lib/libfltk_gl.so.1.3 showed that symbol _ZN18Fl_XFont_On_Demand5valueEv is undefined (with U):
0000a3d4 T _ZN14Fl_Glut_WindowD1Ev

U _ZN18Fl_Font_DescriptorD1Ev
U _ZN18Fl_Graphics_Driver11clip_regionEP8_XRegion
U _ZN18Fl_XFont_On_Demand5valueEv
The solution was to apply a patch file mentioned here to some files inside source directory of FLTK-1.3.3 and then recompile and reinstall FLTK. Now octave works with FLTK without any problem.
I'm trying to implement a Netezza UDX that uses R language through Rserve (therefore I use Rconnection library for C++). Currently I've written only the bare minimum required for the UDX to run.
It looks as follows:
#define MAIN
// Netezza UDX libraries
#include "udxinc.h"
#include "udxhelpers.h"
// C++ libraries
#include <cstdlib>
#include <cstring>
// external Rserve and R headers
#include "Rconnection.h"
#include "sisocks.h"
using namespace nz::udx::dthelpers;
using namespace nz::udx_ver2;
// extends UDF base class
class My_UDX : public Udf {
public:
Rconnection * rc;
My_UDX(UdxInit *pInit) : Udf(pInit) {
initsocks();
// IP address in place of ...
rc = new Rconnection("...", 6311);
};
~My_UDX() {
delete rc;
}
static Udf* instantiate(UdxInit *pInit);
virtual ReturnValue evaluate();
};
Udf* My_UDX::instantiate(UdxInit *pInit) {
return new My_UDX(pInit);
}
// called once for each row of data during execution
ReturnValue My_UDX::evaluate() {
int32 retval = 15;
NZ_UDX_RETURN_INT32(retval);
}
The problem arises when I try to test the UDX with a SQL query. My query looks like this:
SELECT * FROM table_name WHERE My_UDX(table_field) = 1;
And this is the error message I get:
Testing...
nzsql -d database_name -u my_username -pw my_password -f sql/test.sql
nzsql:sql/test.sql:1: ERROR: /dev/shm/spuplans/63_1_3.o: undefined symbol: _ZN11RconnectionC1EPKci : loading executable code
make: *** [update] Error 2
If I remove the Rconnection object, UDX works just fine.
I've checked different manuals about Netezza UDXs, Rserve, and Rconnection but with no results. Couldn't find any explanation to this error and what could be done to resolve it.
Then I assumed there might be something wrong with the compiling process, inclusion of needed libraries and flags. I'm not so familiar with makefiles so this is quite a possibility. My makefile looks like so:
# list of files
function_name = My_UDX
object_files = $(function_name).o_x86
spu_files = $(function_name).o_spu10
# database connection
db_call = nzsql -d database_name -u my_username -pw my_password -f
# path to directories
lib_dir = /home/nz/libs
r_connection_dir = /home/nz/Rconnection
all: update
update: compile
$(db_call) sql/unload.sql
cp $(object_files) $(lib_dir)
cp $(spu_files) $(lib_dir)
rm -f *.o_spu10 *.o_x86
$(db_call) sql/create.sql
$(db_call) sql/test.sql
compile:
nzudxcompile $(function_name).cpp --args -I$(r_connection_dir)
unload.sql just drops the previously loaded function and create.sql just creates it. The problem arises only when the test.sql with the previously shown SQL query is executed.
Have been trying to resolve this issue for quite a long time so any help would be appreciated!
As mentioned above by Alex, Rconnection had to be loaded as a shared library or compiled along with the UDF. Solved this by compiling with the UDF.
# for host environment
nzudxcompile --host Rconnection.cpp -o temp_rconnection.o_x86
nzudxcompile --host myudf.cpp -o temp_myudf.o_x86
nzudxcompile --host --objs temp_rconnection.o_x86 --objs temp_myudf.o_x86 -o myudf.o_x86
# for spu environment
nzudxcompile Rconnection.cpp --spu -o temp_rconnection.o_spu10
nzudxcompile myudf.cpp --spu -o temp_myudf.o_spu10
nzudxcompile --spu --objs temp_rconnection.o_spu10 --objs temp_myudf.o_spu10 -o myudf.o_spu10
