我的问题:,我正在用C++写一个象棋引擎。编写国际象棋引擎的一部分是处理非常大的数字(可以想象高达2^63)。我有一个文件正在为我的项目运行单元测试,当我试图运行构建任务将其编译成一个可执行文件时,我会得到以下错误:
C:/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/as.exe: C:\Users\chopi\AppData\Local\Temp\ccEvO3si.o: too many sections (32782)

我尝试过的内容:编译时应该像传递/bigobj、-bigobj或-Wa和-mbig-obj选项一样简单。因此,我尝试了一些应该(但不是)用启用大对象编译我的代码的方法。这就是我的tasks.json的样子:
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "C/C++: g++.exe build active file",
"command": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-posix-seh-rt_v6-rev0\\mingw64\\bin\\g++.exe",
"args": [
"-g",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
}但我也试过这样的:
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "C/C++: g++.exe build active file",
"command": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-posix-seh-rt_v6-rev0\\mingw64\\bin\\g++.exe",
"args": [
"-g",
"-bigobj",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
}和
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "C/C++: g++.exe build active file",
"command": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-posix-seh-rt_v6-rev0\\mingw64\\bin\\g++.exe",
"args": [
"-g",
"-Wa",
"-mbig-obj",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
}...among其他人。
这些配置产生了g++.exe: error: unrecognized command line option '-bigobj'和
g++.exe: error: unrecognized command line option '-Wa'; did you mean '-W'?
g++.exe: error: unrecognized command line option '-mbig-obj',分别。
我想知道的是:那么,有什么方法可以解决Visual代码中的"too many sections"错误吗?还是我必须咬紧牙关,为Visual 配置所有东西?

正如user4581301所建议的,我不能将-Wa和-mbig-obj作为两个独立的选项分开。相反,我不得不保留它们作为一种选择:-Wa,-mbig-obj。这遇到了一个错误,但是,根据this answer,添加--%作为第一个参数,再加上前面关于选项的建议,我的代码最终编译成了一个可执行文件。以下是更改后的tasks.json的样子:
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "C/C++: g++.exe build active file",
"command": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-posix-seh-rt_v6-rev0\\mingw64\\bin\\g++.exe",
"args": [
"--%",
"-g",
"-Wa,-mbig-obj",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
