: 商业公司，采用 LGPL 协议进行 Qt开发有什么问题吗
:

去官网查了一下关于licence的ASK：
===========================================================
Can I use the Community open source version to develop my commercial product?
-----------------------------------------------------------------------------------
It depends on how you license and distribute your product. The open source version of Qt is mainly distributed under the LGPL, version 3 and GPLv2/v3. You will need to fulfill the license obligations for these licenses when using Qt in your product.

看来只要对应产品遵循开源协议就可以了。
============================================================
Why is Qt licensed also under an open source license?
------------------------------------------------------------------------------------
We believe in the Free Software movement where using software comes with certain rights, but also certain obligations. Use of open source licensing gives users four primary degrees of freedom when using Qt applications or devices:

The freedom to run the program for any purpose
The freedom to study how the program works and adapt it to specific needs
The freedom to redistribute copies so you can help your neighbor
The freedom to improve the program and release your improvements to the public, so that the whole community benefits
The freedoms are non-negotiable and absolute, the freedoms cannot be enjoyed selectively or partially, you also need to pass them to your users.

The Free Software community has thrived because of these rules, but there are also developers who never intend to observe or cannot comply to these rules, and thus should get a commercial license. The Qt Company exists to support both sets with the dual offering.

明确说明， 如果你的产品无法或者不愿遵循开源协议， 就需要商业licence。
