I have trying to compile a collection of old fortran and C codes with gfortran. They compile fine on a linux workstation but this fails in a Mac. Any idea on how to solve this ? The Makefile in the Linux version has one extra flag in CFLAGS and FFLAGS -mcmodel=large that I removed following some advice.
This is the error at the final linking line.

I made a project split in three folders : src, include, obj
I am using CImg.h and cuda.h library.

Here is my issue : it says the reference to void convolve(cimg_library::CImg<float>&, cimg_library::CImg<float> const &) is undefined.
I think this is because I never clearly say to the compiler that the definition of convolve is in convolve.cu. But I do not find how to make this link properly.
Thanks for your help !
please don't post code (or Makefile contents) with line numbers. It just gets in the way, usually.
The compilation process here follows a compile...link process. The first stage is the compile stage, and you should be using -c for both g++ and nvcc during this stage (i.e. for both types of Makefile targets)
nvcc has no -cu option. I think maybe you meant -x cu
I also removed the ampersands on the function call.
Here is a simplified example based on what you have shown, primarily removing the CImg stuff and some other unnecessary items:
$ cat main.cpp
#include "convolve.h"
int main(){
int var1 = 0;
int var2 = 1;
convolve(var1, var2);
}
$ cat convolve.h
void convolve(int &, int &);

change the instances of cuda-9.1 to cuda-9.0 in the above Makefile if you have CUDA 9.0 in your setup. The linker libs (-L) are not really needed for the compile commands, however. When linking with nvcc as we are doing here, it's also unnecessary to pass the -I and -L switches that refer to the CUDA includes and CUDA libraries that are part of the toolkit. nvcc already knows how to find those.
There may be any number of additional recommendations or tweaks to the Makefile, for instance the -x cu and -x c++ switches are probably unnecessary (at least they are unnecessary for my simplified example) but my objective here is not to create the perfect Makefile, but to give you a roadmap to get past the issue you are currently witnessing.

I'm using makefile to compile my simple application. Here it is:

However, it seems that I have a problem with linking static library. This is my output after executing make all:
$ make all
g++ -Wall -c main.cpp
g++ -Wall -c section.cpp
g++ -Wall -c circle.cpp
g++ -Wall -c triangle.cpp
g++ -Wall -c rectangle.cpp

g++: error: main.x: No such file or directory 1
make: *** [main.x] Error 1
Any ideas what am I doing wrong with this makefile?
Your final command is
g++ -o main.x -Wall main.o section.o circle.o triangle.o rectangle.o \
libfigures.a main.x main.o section.o circle.o triangle.o \
rectangle.o
There's too much going on here: you (1) repeat each object twice (2) use both objects and a library built from them (3) use the output file in the list of input files.
It should be
g++ -o main.x main.o libfigures.a
You probably need to modify the makefile rule like this:
$(MAINEXE): $(MAINKOM) $(BIBSTAT)
$(LINKER) -o $# $^

I started a little experiment today: I wrote a C++ class which depends on some other libraries (ALGLIB, Eigen, internal tools) and I wanted to create a Ruby wrapper for that class. I'm currently using Rice to do that. First I wrote a very simple C++ wrapper for my class:
// #file MLPWrapper.h
#pragma once
#include "mlp/MLP.h"
#include <ruby.h>
class MLPWrapper
{
MLP mlp; // <- my C++ class
public:
...
void fit()
{
...
mlp.fit(stop);
}
};
The library's cpp-file is this:
// #file cmlp.cpp
#include "rice/Data_Type.hpp"
#include "rice/Constructor.hpp"
#include "MLPWrapper.h"
using namespace Rice;
extern "C"
void Init_cmlp()
{
Data_Type<MLPWrapper> rb_cMLPWrapper = define_class<MLPWrapper>("MLP")
.define_constructor(Constructor<MLPWrapper>())
...
.define_method("fit", &MLPWrapper::fit);
}
And this is the extconf.rb:
require "mkmf-rice"
$CFLAGS << "-O3"
HEADER_DIRS = [
"..",
"../../external/libraries/eigen-eigen-3.0.1",
"../../external/libraries/alglib/cpp/src",
"../../external/libraries/CMA-ESpp"
]
LIB_DIRS = [
"../../build/external/libraries/alglib/cpp/src",
"../../build/external/libraries/CMA-ESpp/cma-es",
"../../build/src/tools"
]
dir_config("libs", HEADER_DIRS, LIB_DIRS)
have_library("libtools")
have_library("libalglib")
create_makefile("cmlp")
Everything works fine except linking. Obviously the header files of the libraries are included, otherwise it would not compile. But when I run a little test program ("require "cmlp"; mlp = MLP.new") in Ruby it does not find the symbol _ZN6LoggerC1ENS_6TargetESs, which is part of libtools (an enum). This is what happens when I build the C++ extension and execute the test program:

I don't know how to solve this problem on my own and I could not find any helpful documentation for my problem. How do i fix this extconf.rb? I appreciate every hint.

could be the problem. I would try absolute paths here, I could imagine that the pwd is a different one than you expected while running ruby extconf.rb.
Also, I assume you need a dir_config entry for each library you'd like to link in. So
dir_config('libs', HEADER_DIRS, LIB_DIRS)
should be replaced by
dir_config('tools', '<Path to include dir>', '<Path to lib dir>')
dir_config('alglib', '<Path to include dir>', '<Path to lib dir>')
Note that the leading 'lib' should be omitted, just like you would in the -l linker option.
Next, if you want to be absolutely sure that a library is found, replace
have_library('libtools')
by
have_library('tools') or raise
Again, 'lib' is omitted.
If you still can't solve the problem, please post the Makefile generated by `ruby extconf.rb'.
