Originally posted on https://github.com/jbeder/yaml-cpp/issues/481
I just noticed 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./libraries/yaml-cpp/include -L./libraries/yaml-cpp -lyaml-cpp -o main on the command line, it works.
These are the Sublime Text .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": "$project_path/source",
"target": "exec",
"syntax": "Packages/Text/Plain text.tmLanguage",
}
]
}
And this is the make_run.sh file:
g++ --std=c++11 main.cpp -I. -I./libraries/yaml-cpp/include -L./libraries/yaml-cpp -lyaml-cpp -o main
exit 0
Was also opened a issue on https://github.com/SublimeTextIssues/Core/issues/1632 _ Why Sublime Text is making the linker ld.exe not link?
I found out to instead of running things inside the buggy Sublime Text environment, call/open a shell window to run the shell script:
#!/bin/sh
CURRENT_PATH=$(pwd)
COMMAND_TO_RUN="pwd; echo $CURRENT_PATH; cd $CURRENT_PATH; sh make_run.sh $@"
echo "choose_a_compiler.sh: $CURRENT_PATH"
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
fi
current_terminal="xfce4-terminal"
if command -v $current_terminal >/dev/null 2>&1; then
/usr/bin/$current_terminal --maximize --hold --command="$COMMAND_TO_RUN"
exit 0
fi
# TODO
# "konsole" "gnome-terminal" "xterm"
Just replaced the "make_run.sh on the .sublime-build file by this script choose_a_compiler.sh, and inside this script, call your make_run.sh. Now everything is building fine, but sadly it is on a new windows, instead of on the Sublime Text build output console.
