Why Sublime Text is making the linker ld.exe not link?

[evandrocoan]

Expected behavior

This error only happens if I call it from a shell script called by Sublime Text .sublime-build file. If I directly call the command g++ --std=c++11 main.cpp -I. -I./yaml-cpp/include -L./yaml-cpp -lyaml-cpp -o main on a command line as mintty 2.6.2 (x86_64-pc-cygwin), it works correctly.

It is expected to the linker to be able to link from Sublime Text.

Actual behavior

undefined reference to `YAML::Parser::~Parser()

C:\Users\PROFES~1\AppData\Local\Temp\ccRhYWZh.o:main.cpp:(.text+0x1b1): undefined reference to `YAML::Parser::Parser(std::istream&)'
C:\Users\PROFES~1\AppData\Local\Temp\ccRhYWZh.o:main.cpp:(.text+0x2d8): undefined reference to `YAML::Parser::~Parser()'
C:\Users\PROFES~1\AppData\Local\Temp\ccRhYWZh.o:main.cpp:(.text+0x38e): undefined reference to `YAML::Parser::~Parser()'
collect2.exe: error: ld returned 1 exit status

Steps to reproduce

1. Clone the project https://github.com/jbeder/yaml-cpp

2. Open a command line as mintty.exe shell on yaml-cpp folder and build it on windows@cygwin with:

$ cmake -G "Unix Makefiles"
$ make

3. Create these following files on the folder yaml-cpp you just cloned:

This is the Sublime Text project.sublime-project:

{
    "folders":
    [
        {
            "path": ".",
        },
    ],
    "build_systems":
    [
        {
            "file_regex": "^(..[^:]*):([\\d+]):?(\\d+)?:? (.*)$|^\\(.*\\)\\((\\d+)\\)(.*)$",
            // "selector": "source.c, source.c++, source.c++11", // comment this to build from everywhere

            "name": "Build Main file",
            "cmd": ["sh", "make_run.sh", "main"],

            "working_dir": "$project_path",

            "target": "exec",
            "syntax": "Packages/Text/Plain text.tmLanguage",
        }
    ]
}

And this is the make_run.sh file:

g++ --std=c++11 main.cpp -I. -I./yaml-cpp/include -L./yaml-cpp -lyaml-cpp -o main
exit 0

Create this file named main.cpp:

#include "yaml-cpp/yaml.h"

#include <iostream>
#include <sstream>
#include <cstdlib>

#include <fstream>
#include <string>
#include <vector>

int main( int argumentsCount, char* argumentsStringList[] )
{
    std::ifstream fin("test.beauty-blocks");
    YAML::Parser parser(fin);
}

4. Press Ctrl+Shift+B and select the Build Main file option. You will get:

undefined reference to `YAML::Parser::~Parser()

C:\Users\PROFES~1\AppData\Local\Temp\ccRhYWZh.o:main.cpp:(.text+0x1b1): undefined reference to `YAML::Parser::Parser(std::istream&)'
C:\Users\PROFES~1\AppData\Local\Temp\ccRhYWZh.o:main.cpp:(.text+0x2d8): undefined reference to `YAML::Parser::~Parser()'
C:\Users\PROFES~1\AppData\Local\Temp\ccRhYWZh.o:main.cpp:(.text+0x38e): undefined reference to `YAML::Parser::~Parser()'
collect2.exe: error: ld returned 1 exit status

But that error only happens if you call make_run.sh from Sublime Text build file. If you open a shell command line as mintty 2.6.2 (x86_64-pc-cygwin) it works correctly calling ./make_run.sh to build.

Why Sublime Text is making the linker ld.exe not link?

Environment

• Operating system and version:
  • Windows 10 @ mintty 2.6.2 (x86_64-pc-cygwin)
  • Mac OS ...
  • Linux ...
• Sublime Text:
  • Build 3114

I am on windows with Cygwin:

3. How to build yaml-cpp on Windows/Cygwin on Sublime Text?

[keith-hall]

if you execute sh make_run.sh main from a Windows Command Prompt when in the project direcdory, what happens? and does sh launch this mintty 2.6.2 (x86_64-pc-cygwin) shell of yours?

[evandrocoan]

This happens: (it does compile successfully, which is the opposite of running it from Sublime Text build)

It does not launch a windows because I am not launching the mintty shell terminal anywhere on that script. It cannot magically open, but if you put this on the shell script called open_shell.sh and inside it call sh make_run.sh main, it does launch the mintty shell terminal if I call open_shell.sh instead of make_run.sh on the Sublime Text build:

CURRENT_PATH=$(pwd)
COMMAND_TO_RUN="pwd; echo $CURRENT_PATH; cd $CURRENT_PATH; sh make_run.sh $@"

current_terminal="mintty"

if command -v $current_terminal >/dev/null 2>&1; then
    /bin/$current_terminal -w max -h always -e /bin/bash --login -i -c "$COMMAND_TO_RUN"
    exit 0

This seems to be just more one new issue with the Sublime Text build system:

1. The build panel, it is severally cutting out lines of its output #1606 _ The build panel, it is severally cutting out lines of its output

The only thing to do overcome these problems is launching a new window running a full shell terminal, as showed on the StackOverflow answer above, instead of relying on the Sublime Text build system/environment.
