Linux kernel 将yocto morty更新为thud后出现内核编译错误

我在yocto morty上使用了“linux-toradex-4.1-2.0.x-imx”，一切正常。但在将所有层和poky更新为“Thud”版本后，我得到了内核do_编译错误：

内核配方是：

include conf/tdx_version.conf

在“meta-toradex nxp”层中，我只看到了“linux-toradex_4.9-2.3.x.bb”，而不是4.1-2.0.x，这重要吗？我是否需要在我的食谱中添加其他东西，以便也使用“Thud”进行编译

我的bblayers.conf也是：

# changes incompatibly
LCONF_VERSION = "7"

事先非常感谢你

更新：谢谢@Marcel，我检查了它，它说：“GNU编译器集合版本8.2现在默认用于编译。如果您仍然需要使用版本7.x进行编译，还提供了GCC 7.3。您可以通过设置来选择此版本，也可以通过将GCCVERSION变量设置为“7”来选择。”“在您的配置中。”

---

然后我也在conf/local.conf中插入了'GCCVERSION=“7.%”，但不幸的是它仍然不能工作。

请注意，Thud使用的是更高版本的gcc编译器（准确地说是8.3）。不幸的是，过时的Linux内核4.1无法使用gcc 8.3进行编译，您需要备份多个修补程序才能使这种组合正常工作。另外请注意，OpenEmbedded通常将任何警告视为错误，您可能还希望通过编译标志禁用，否则，所需的修补程序数量将非常有限ndless。总的来说，更好的方法可能是适当地采用后来仍然受支持的Linux内核，如toradex_4.14-2.0.x-imx，我们现在正式在BSP 3.0b2中使用它。

在编译新版本（thud）之前，您是否正确地清理了构建环境？OTOH，您所说的“重要吗？”？"? 如果你愿意，你也可以升级你的内核。你不是通过@danlor使用这个Toradex环境吗？@danlor是的，我已经完全使用了另一个构建目录。“Thud”和“Morty”只共享下载文件夹。关于内核，不，实际上我不想升级内核，我将在morty中使用我的内核，即4.1-2.0。@Nayfe不，我不使用它。我也需要它吗？你不需要使用它，但它有助于选择由Toradex测试的图层和配方版本。非常感谢，你完全正确。正如手册所说，“…GCC 7.3也提供了”，我是否也可以使用GCC 7.3编译内核4.1？
