Good morning

This is my first time install nim on my windows 10 development laptop. I have copied the necessary dll's and also downloaded the mingw64 compiler.

Firstly, to make a simple program compile and run in windows 10 I had to include my gcc path manually here:

Configuration for the GNU C/C++ compiler:

@if windows:

gcc.path = r"C:mingwbin"

@if gcc or tcc:: tlsEmulation:on

@end

However, I cannot seem to run this command to build for macos: nim -d:release --os:macosx --cpu:amd64 c hello.nim

This is the error generated? what else must I change in the nim.cfg file? Error: invocation of external compiler program failed. The system cannot find the file specified. Additional info: "Requested command not found: 'clang.exe -c -w -O3

Hi, I really really recommend you try the excellent choosenim project https It not only helps manage different versions, but installs and configures the required compiler for you on windows.

Hi, thank you so much for the reply. I have since installed Virtual Box and installed latest UBUNTU desktop iso... trying to fire up Visual Studio Code, Nim and the LLVM binaries ... struggling to set the path to CLANG.

If it IS in fact possible to cross compile to MACOSX, ANDROID etc. FROM windows 10 i would like to stick to Windows 10 - purely due to my decades of working primary on windows ...

This is 'greek' to me at this stage "compile toolchain for GCC setup to make that configuration work."

Is it possible to compile for MAC OSX on windows 10 when compiling a NIM program - or must i install UBUNTU?

If you're up to some experimenting, you could try using Nim with Zig as your C cross-compiler - see:

https://ziglang.org/#Zig-is-also-a-C-compiler

https://ziglang.org/#Cross-compiling-is-a-first-class-use-case

https://ziglang.org/#Zig-ships-with-libc

I don't guarantee it will work, but there's a chance. I believe I managed to get it to cross-compile from Windows to Android once.

Hi, I'm still new to Nim and this is my first post. Although Zig is really nice, I'm not sure why you would need it. I was able to somewhat cross-compile from Mac to windows, but I can't remember off-hand the problem I had with compiling with Linux. I ended up finding a solution that I was probably going to use later.: I just recently installed a new system and I haven't restored my backups yet. I had found there are some other compiler options for, but I can only think of one that I found. I'm posting a couple links to them. The cross-compile in Zig is nice, but I really liked the way Red/Rebol cross-compiles. You should be able to look at and/or use Nim cross.

I have never cross-compiled from Windows/Linux => OSX but given my experience going the other way, I will recommend first finding an existing C/C++ compiler setup that does that for you before trying within Nim.

https://github.com/tpoechtrager/osxcross is the only real link I have found and it is only for Linux => OSX.

Thank you everyone! Great, I have a virtual box up with latest UBUNTU desktop installed. Managed to compile easy to Linux (ubuntu) no issues Also , managed to use mingw-w64 to compile an exe for windows Now, still playing with a way to compile to MacOS - I got a binary file compiled but cannot bash run it or mac os ...?

iwcoetzer (orginal) [2020-02-13T20:36:20+01:00] view original

Good Evening Thank you for all the replies!

I have decided to push on with a new UBUNTU desktop installation in VirtualBOX (host is Windows 10). I managed to get it up and running in the UBUNTU desktop.

Compiling

Managed to use mingw-w64 to compile an executable that works on Windows from Ubuntu :-)

Managed to compile a terminal program for Ubuntu itself that is working :)

I am still trying to see if I can compile a program (simple terminal app) for MacOS Sierra
not working :-(
- I managed to use this type of nim commands to get a binary compiled
  
  nim -d:release --os:macosx --cpu:amd64 c "/home/ian/Desktop/nimproject/hello"
- but macOS Sierra does not want to run this thing vir a terminal using bash ./hello ...

Yardanico (orginal) [2020-02-13T20:55:12+01:00] view original

You shouldn't run it with bash, you should just run it like ./hello after doing chmod +x hello on the resulting macOS machine

iwcoetzer (orginal) [2020-02-14T10:17:53+01:00] view original

Hi, I have tried that on macOS Sierra. I simply receive something like this "Command not Found" Then I tried the bash ./hello and it said permissions denied so i tried sudo bas ./hello and it said "Cannot run Binary File" <- something like this

mp035 (orginal) [2020-02-14T12:56:35+01:00] view original

Hi, If you have access to a MacOS machine, why not just compile natively from MacOS?

Yardanico (orginal) [2020-02-14T13:53:24+01:00] view original

well, try this:


chmod +x hello
./hello

and also show output of file hello command

iwcoetzer (orginal) [2020-02-14T20:07:52+01:00] view original

I am just trying to see if it is possible to compile for Windows, Ubuntu, Android, MacOSX from a primary UBUNTU instance.

Yardanico (orginal) [2020-02-14T20:38:05+01:00] view original

You can for sure compile for windows/ubuntu/android, it might be harder for macOS though, although you can set up a VM for it

iwcoetzer (orginal) [2020-02-16T11:47:19+01:00] view original

Hi I have tried to run the macos binary - that I compile using Ubuntu and this is what happens :-(

chmod +x hello ** this runs fine - no errors

./hello

cannot execute binary file :-(

You can try using this Docker image. It supports cross compiling directly, but you can also look at how the Docker image is setup to get more info about how you might do it yourself.

Thank you, I managed to pull that docker image and create a new container. Then I managed to share my local code volume with that container while running and compile it successfully as per instructions. Now I have a hello64.osx.bin file... what now, I copied it to a macbook and how do i run this file on a macos?

iwcoetzer (orginal) [2020-02-17T15:04:44+01:00] view original

hang on it works! I opened up terminal - navigate to Desktop (cd Desktop) where I copied the ...osx.bin file.

Then I simply executed it like this ./hello64.osx.bin !!! and the echo message appeared - no errors.
