意外标记“(”附近出现语法错误

下面是我的代码，它一直告诉我第 10 行导致了这个“意外标记‘(’附近的语法错误”，但我不明白为什么。我正在添加到已经编写的代码中，但它说有的部分错误不是我添加的内容的一部分。所以我对为什么会收到此错误感到非常困惑。此外，我想要一个关于此错误实际含义的良好定义。

将OP的评论编辑到问题中:

unix> g++ applanixraw2out.c
unix> ./applanixraw2out.c applanix_raw_20120508.bin > test.txt
./applanixraw2out.c: line 10: syntax error near unexpected token ('

这不是编译器语法错误，而是 shell 错误。

您正在尝试直接执行 C 源代码。系统假设该文件是 shell 脚本。

您需要将其编译为可执行文件，然后运行该可执行文件：

$ gcc applanixraw2out.c -o applanixraw2out
$ ./applanixraw2out [arguments]

在评论中，您说您做了以下事情：

unix> g++ applanixraw2out.c
unix> ./applanixraw2out.c applanix_raw_20120508.bin > test.txt
./applanixraw2out.c: line 10: syntax error near unexpected token ('

The g++命令用于 C++ 代码；你的代码是C，所以你应该使用gcc反而。

您必须指定可执行文件的名称，最常见的是源文件名.c已删除。如果你不这样做，两个g++ and gcc生成一个名为的可执行文件a.out默认情况下（由于历史原因）。使用-o覆盖该默认值的选项。

另外，为了得到该语法错误，您必须执行以下操作：

$ chmod +x applanixraw2out.c

对不应该执行的文件设置执行权限是基本上无害 http://en.wikipedia.org/wiki/Phrases_from_The_Hitchhiker%27s_Guide_to_the_Galaxy#Mostly_Harmless，但应该避免，因为它会使此类错误更难以追踪。
