c++ - 在自己的工作目录中运行可执行文件

Question

我在运行.sh文件的 gvim 工具栏上添加了一个按钮。该.sh文件运行 scons 以在 /build 子目录中构建我的 c++ 应用程序并运行它。问题是，当应用程序运行时，它的当前工作目录是包含文件的.sh文件夹（而不是应用程序 /build 子目录）！那么如何从.sh文件运行构建的 c++ 应用程序可执行文件（linux），以便其工作目录成为包含可执行文件的文件夹？

Answer 1

只是

 cd $(dirname "$0")
 ./exec_test

注意，你需要 ./exec_test，exec_test除非目录实际上已经在PATH

Answer 2

这是一个类似的例子（我不使用scons。）

我添加我的工具栏图标：

:amenu ToolBar.mytool :!/home/me/code/misc/foo.sh "%"

对我来说，当我单击它时，vim在与vim.

foo.sh包含：

#!/bin/bash

set -e

# You should see the name of your file.
# It might just be "my_file.c"
echo "$1"
# This will tell you where your script is current cd'd to.
pwd

# `cd` to where the file passed on the command line is:
cd "$(dirname "$1")"

# Look for "CMakeLists.txt"
# You only need this loop if your build file / program might be up a few directories.
# My stuff tends to be:
# / - project root
#   CMakeLists.txt
#   src/
#     foo.c
#     bar.c
while true; do
    # We found it.
    if [[ -e "CMakeLists.txt" ]]; then
        break
    fi
    # We didn't find it. If we're at the root, just abort.
    if [[ "`pwd -P`" = "/" ]]; then
        echo "Couldn't find CMakeLists.txt." >&2
        exit 1
    fi
    cd ..
done

# I do builds in a separate directory.
cd build && make

您将替换CMakeLists.txt为SConstruct，最后一个cd build && make替换为scons，或适合scons.
