[error] g++.exe: cannot specify -o with -c or -s and multiple compilations
时间: 2023-04-22 22:04:51 浏览: 893
这个错误提示是因为在使用 g++ 编译器时,同时使用了 -o 参数和 -c 或 -s 参数,并且进行了多次编译。-o 参数用于指定输出文件的名称,而 -c 和 -s 参数则用于分别进行编译和汇编操作。在进行多次编译时,应该只使用 -c 或 -s 参数,而不需要再指定输出文件的名称。如果需要指定输出文件的名称,应该在最后一次编译时使用 -o 参数。

gcc: fatal error: cannot specify ‘-o’ with ‘-c’, ‘-S’ or ‘-E’ with multiple files compilation terminated.
这个错误是因为你在使用gcc编译器时,同时指定了多个源文件,并且使用了"-o"选项来指定输出文件名。但是"-o"选项只能用于单个输入文件的编译,不能和"-c"、"-S"、"-E"等选项一起使用。
如果你想要编译多个源文件并链接成一个可执行文件,应该先编译每个源文件,然后再将它们链接起来,例如:
```
gcc -c file1.c
gcc -c file2.c
gcc -o program file1.o file2.o
```
这样就会先分别编译file1.c和file2.c文件生成对应的目标文件file1.o和file2.o,然后再将它们链接成一个名为program的可执行文件。
如果你只是想编译一个源文件,就不需要使用"-o"选项,例如:
```
gcc -o program file.c
```
这样就会将file.c编译成名为program的可执行文件。

Maven is a popular build automation tool used primarily for Java projects. It uses a plugin-based architecture to provide various functionalities during the build process. The `maven-compiler-plugin` is one of the core plugins in Maven, responsible for compiling Java source code.
The `org.apache.maven.plugins:maven-compiler-plugin:3.8.1` is a specific version of the `maven-compiler-plugin` that you can use in your Maven project. It provides configuration options for the Java compiler, allowing you to specify the source and target versions of Java, enable or disable certain compiler features, and more.
Here are a few key features and configurations provided by the `maven-compiler-plugin`:
1. Source and target versions: You can specify the version of Java source code your project is written in (`source`) and the version of Java bytecode to be generated (`target`). This allows you to use language features specific to a particular Java version while ensuring compatibility with the target environment.
2. Compiler options: The plugin allows you to configure various compiler options such as encoding, debugging information, and compiler optimizations.
3. Compiler plugin executions: You can define multiple executions of the `maven-compiler-plugin`, each with its own configuration. This is useful when you have different sets of Java source code that need to be compiled with different configurations.
4. Compiler plugin dependencies: The plugin can also manage dependencies required during the compilation process, such as annotation processors or additional libraries.
To use the `maven-compiler-plugin`, you need to include it in your project's `pom.xml` file within the `<build>` section. Here's an example configuration:
```xml
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
```
This configuration sets the source and target versions to Java 1.8.
