我想编写一个使用 Trilinos 的简单程序。在配置脚本出现许多问题后，我设法编写了它，因此它可以毫无问题地启动。问题是，当我尝试编译我自己的代码（Makefile 和我的测试程序都根据原始示例重写）时，它会抛出错误：
c++: error trying to exec '/usr/lib/gcc/x86_64-linux-gnu/4.9/cc1plus': execv: Argument list too long
所以我试图启动我的 Makefileenv -i make来为“参数”腾出足够的空间。它有效，但现在它引发了另一个错误：
c++: error trying to exec 'cc1plus': execvp: No such file or directory
Makefile:62: recipe for target 'test.o' failed
make: *** [test.o] Error 1
我的尝试：
我试图找到任何解决这个问题的方法，但到目前为止我还没有找到任何有效的方法。
我检查了我的 GCC 和 G++ 是否是相同的版本，它们是：
gcc (Ubuntu 4.9.1-16ubuntu6) 4.9.1
Copyright (C) 2014 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO

Copyright (C) 2014 Free Software Foundation, Inc.

然后我尝试重新安装 G++：
sudo aptitude reinstall g++-4.9
尽管如此，还是没有成功。
最后，我检查了我的g++命令是否指向正确的目的地：
martin@martin-Aspire-E1-531:~$ which g++
/usr/bin/g++
/usr/bin/g++是文件的链接g++-4.9，它是启动编译器的正确文件。
所以，我不知道我应该知道什么才能正确编译它。你？
