Whats wrong?

After successfully installing using the install_script.bat I am unable to change the .asm source file Item Type to be Netwide Assembler

Are you able to provide any info on how to troubleshoot?

2019 moved the BuildCustomizations to the following location, readme is outdated.
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VC\v160\BuildCustomizations

I just recently installed this mod to visual studio and since then I had problems not just with projects in assembly but with any project. Whenever I compile my source visual studio tells me it cant find the executable that it is atually supposed to create. This problem just started happening after I ran the batch script included in this repo.

Any help is appreciated. Thanks

The use of the 'install_script.bat' script does not work and after the manual installation VS2019 returns the error

Severity Code Description Project File Line Suppression State
Error MSB3721 The command "" C: \ Program Files (x86) \ Microsoft Visual Studio \ NASM "nasm.exe -Xvc -f win64 -o" x64 \ Debug \ parteinassembler.obj "" C: \ Users \ cogaa \ source \ repos \ VSeNasm project \ VSeNasm project \ parteinassembler.asm "" exited with code 1.VSeNasm project C: \ Program Files (x86) \ Microsoft Visual Studio \ nasm utility \ nasm.targets 50

I'm not an expert programmer, thanks for the support
I used this test code

section .text
bits 64
global foo
foo:
mov rax,7
ret

I have a very simple project:

main.cpp

#include <stdio.h>

extern "C" char theText[];

void main()
{
  printf( "%s", theText );
}

data.asm

section .data

global _theText
_theText db "hello!",0

With VS2019, on the first build, or a clean build, everything builds fine and I can run the program and print the string.

However, if I change the string in the .asm and press Build again, I get this: (msbuild set to Diagnostic level)

1>------ Up-To-Date check: Project: NasmPropsTest, Configuration: Debug Win32 ------
1>All outputs are up-to-date.
1>Time Elapsed 9 ms
========== Build: 0 succeeded, 0 failed, 1 up-to-date, 0 skipped ==========

Changing the .cpp file and pressing Build correctly rebuilds the .asm file as well.

I tried running install_script.bat file as an Administrator and it could not find a fresh install of MS VS 2019.

I have both visual studio 2015 and 2017 installed, but the installer "install_scrip.bat" only finds VS2015 and thus only installs for VS2015.

Hi,
thanks for the tool. I really appreciate it.

However I'm facing an issue. By default nasm is invoked with some options as -Xvc and -f win32.
This is not always the case since not all projects containing an asm file to be processed by nasm are related to win32 and obj files or the other default options, -Xvc.

Is it possible to have by default only nasm invoked on an item? And under the properties of the project the possibility to insert or specify manually which options I'd like to have?

I've given a look at nasm.xml, .targets, and .props files and my intention was to modify them inorder to achieve the above goal but I don't know those formats (MSBuild?) and at the same time they seem to be interrelated.

Thanks

The install script needs to be adapted for version 17.0 of Visual Studio, and probably for 64 bit as well.

Hello, I have set everything up and manually installed it. I made a new empty C++ project and deleted all the folders and set it to Build customization NASM, and went to the .asm file's properties and set it to Netwide Assembler, but with

section .data

section .text
global main

main:
	mov eax, 5

to test if it works I get the error as in the title (LNK2001: unresolved external symbol mainCRTStartup). If you need any more info or have any idea how to fix it, please let me know!

Unhandled exception at 0x00D63014 in nasm.exe: 0xC0000005: Access violation when reading at address 0xFFFFFFFF.

If I run compatible with VS 2010, I cannot debug app.
And for VS 2017 I should use msvcrt.lib;legacy_stdio_definitions.lib (and also debugging doesn't work)

Step by step, breakpoints.

Is there a chance to support parallel execution of NASM tasks in visual studio? What I observe is that NASM tasks are executed one-after-another. And this keeps 8+-16 core CPUs idle for a long time.
One of the examples of projects that could benefit from parallel asm compilation is ffmpeg avcodec.
