I'm trying to call some objective-c code from within ocaml.
stubs.m
#include <Cocoa/Cocoa.h>
#define CAML_NAME_SPACE
#include <caml/mlvalues.h>
#include <caml/memory.h>
#include <caml/callback.h>
#include <caml/alloc.h>
#include <caml/fail.h>
CAMLprim value ml_NSLog (value str)
{
CAMLparam1 (str);
NSLog (#"%s", String_val (str));
CAMLreturn (Val_unit);
}
It gets compiled with the following command to stubs.o:
cc -Wextra -Wall -Werror -O -g -std=c99 -pedantic-errors -Wsign-compare -Wshadow -I /Users/Iwan/.opam/4.02.3/lib/ocaml -c -o stubs.o stubs.m
My ocaml code in index.ml is:
external _NSLog: string -> unit = "ml_NSLog"
let log s = _NSLog s
let () = log "hello"
When I execute ocamlopt -o app index.ml stubs.o I get:
Undefined symbols for architecture x86_64:
"_NSLog", referenced from:
_ml_NSLog in stubs.o
(maybe you meant: _ml_NSLog)
"___CFConstantStringClassReference", referenced from:
CFString in stubs.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
File "caml_startup", line 1:
Error: Error during linking
Why do I get the error in this case?
The solution was brutally simple:
ocamlopt -cclib "-framework Cocoa" -o app index.ml stubs.o
I had to pas "-framework Cocoa" as option to the c linker...

I wonder how CMake automatically detects that main.cpp depends on header.h
// header.h
int f() {
return 0;
}
// main.cpp
#include "header.h"
int main() {
return f();
}
# CMakeLists.txt
cmake_minimum_required(VERSION 3.16)
project(Cppref)
add_executable(main main.cpp)
When I run cmake . -B build it creates the following make target in ./build/CMakeFiles/main.dir/build.make
CMakeFiles/main.dir/main.cpp.o: CMakeFiles/main.dir/compiler_depend.ts
#$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --green --progress-dir=/home/nikolay/Cpp/Train/Cppref/build/CMakeFiles --progress-num=$(CMAKE_PROGRESS_1) "Building CXX object CMakeFiles/main.dir/main.cpp.o"
/usr/bin/c++ $(CXX_DEFINES) $(CXX_INCLUDES) $(CXX_FLAGS) -MD -MT CMakeFiles/main.dir/main.cpp.o -MF CMakeFiles/main.dir/main.cpp.o.d -o CMakeFiles/main.dir/main.cpp.o -c /home/nikolay/Cpp/Train/Cppref/main.cpp
Pay attention to the -MD compiler option, as
it is used to dump dependencies visible to the preprocessor.
So after the first build it will create ./build/CMakeFiles/main.dir/main.cpp.o.d with the following content
CMakeFiles/main.dir/main.cpp.o: /home/nikolay/Cpp/Train/Cppref/main.cpp \
/home/nikolay/Cpp/Train/Cppref/header.h
So whenever you change header.h, the target main.o will be rebuilt.
I'm trying to compile cpputest with mingw-w64 but can't make it work and I can't find any resources on how to do that. So hopefully this question will help others in the future.
I would like to compile cpputest using mingw-w64, preferably without installing MSYS2 or other packages.
I have mingw-w64 i686-8.1.0-posix-dwarf-rt_v6-rev0 installed. I've cloned cpputest from here.
I tried following Compiling Google test with Mingw-w64 and Compiling and using CppUTest 3.8 under MSYS2/MinGW32 by calling CMake with:
cmake ^
-G "MinGW Makefiles" ^
-D CMAKE_C_COMPILER=gcc.exe ^
-D CMAKE_CXX_COMPILER=g++.exe ^
-D CMAKE_MAKE_PROGRAM=mingw32-make.exe ^
-D C++11=ON ^
.
Which yields:

But that still fails with the same error.
So I tried following Build error with CMake and MSYS2 mingw-w64 by installing MSYS2 and then mingw-w64, CMake and Ninja. That gives:

I am trying aot cross compiling with bazel.But failed in platform.h fatal error 'mutex' file not found.I can build with bazel without cross compile setting, and I can exec the binary in host.
My environment is below
x86-64 ubuntu14.04
target:arm-linux-gnueabihf
tensorflow:Head of maste cd5f3b67fca88217776522182481b0c128db5af9
bazel:0.5.4 installed by apt-get install
My test code is below.
#define EIGEN_USE_THREADS
#define EIGEN_USE_CUSTOM_THREAD_POOL
#include <iostream>
#include "third_party/eigen3/unsupported/Eigen/CXX11/Tensor"
#include "tensorflow/compiler/aot/tests/test_graph_tfmatmul.h" // generated
int main(int argc, char** argv) {
Eigen::ThreadPool tp(2); // Size the thread pool as appropriate.
Eigen::ThreadPoolDevice device(&tp, tp.NumThreads());
foo::bar::MatMulComp matmul;
matmul.set_thread_pool(&device);
// Set up args and run the computation.
const float args[12] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12};
std::copy(args + 0, args + 6, matmul.arg0_data());
std::copy(args + 6, args + 12, matmul.arg1_data());
matmul.Run();
// Check result
if (matmul.result0(0, 0) == 58) {
std::cout << "Success" << std::endl;
} else {
std::cout << "Failed. Expected value 58 at 0,0. Got:"
<< matmul.result0(0, 0) << std::endl;
}
return 0;
}
I modified the some files to compile.
add cross compile setting to WORKSPACE file
new_local_repository( name = "linaroLinuxGcc49Repo", build_file =
"compilers/linaro_linux_gcc_4.9.BUILD", path =
"compilers/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf", )
add build setting in /tensorflow/compiler/aot/tests/BUILD
cc_binary(
name = "my_binary",
srcs = [
"my_code.cc", # include test_graph_tfmatmul.h to access the generated header
],
deps = [
":test_graph_tfmatmul", # link in the generated object file
"//third_party/eigen3",
],
linkopts = [
"-lpthread",
] )
Below is the build command I did.
bazel build --copt=-Wno-c++11-narrowing --cxxopt='-std=c++11'

I think path above is setted in the build output line "-isystem external/linaroLinuxGcc49Repo/include/c++/4.9.4"
How could I set the path to mutex? for cross compiling nsync?
I made a mistake when I edit CROSSTOOL file.

Thanks for reviewing the problem. There is an object c file called try.m, and I complie it to an object file try.o with the command:
gcc -c try.m -o try.o -framework Foundation
the try.h is
int print_word( void );
The try.m is:
#include "try.h"
#import <Foundation/Foundation.h>
int print_word( void )
{
NSLog (#"say hello");
return 0;
}
Additionly, there is a main.c file, which contain the main() function, and it looks:
#include <stdio.h>
#include "try.h"
int main()
{
printf( "This is main\n");
}
I compile main.c to main.o by the following command:
gcc -o main.o -c main.c
Then, I link the main.o and try.o to form the executable file main:
gcc -o main main.o try.o
After these steps, the following errors happened:
enter image description here
The errors are:
Undefined symbols for architecture x86_64:
"_NSLog", referenced from:
_print_word in try.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
How could these errors be solved?
You need to link against the Foundation framework. You can do it all in a single command: gcc main.c try.m -framework Foundation.
