有谁知道 Minix 3 的许可证是否兼容 GPL?这是一个 BSD 风格的许可证,但我不完全确定它是否与 GPL 兼容。
答案1
这里是 MINIX 3 许可证:

前三个子句正是BSD 3 条款许可证,即与 GPL 兼容。第四条是多余的,任何其他使用均属侵犯版权,除非版权所有者明确许可。因此 MINIX 许可证是 GPL 兼容的。
答案2
Minix 3 许可证看起来非常相似标准 BSD 风格许可证它比 GPL 更宽松,例如,它将允许以二进制形式将软件用于商业用途,而无需强制发布源代码。
它被认为是自由软件(像任何 BSD 软件一样),但是与GPL不兼容主要是因为“广告条款”。 GPL 往往具有更多限制。换句话说,虽然 GPL 确实允许软件的商业用途,但它确实强制现在和将来根据 GPL 发布源代码(对于任何进一步修改它的人)。 BSD 风格许可证允许发布没有源代码的二进制版本的软件,无论它是未经修改还是已被进一步修改。
