esp-gdbstub编译错误
[英]esp-gdbstub compilation errors
问题描述
我正在尝试使用esp-gdbstub调试用于控制mod-wifi-esp8266-dev的代码。 这是我的原始makefile：

我尝试按照用法部分的说明进行操作：
- 抓取gdbstub项目，并将文件放在项目中名为“ gdbstub”的目录中。 您可以通过签出Git仓库，或者将Git仓库作为子模块添加到项目中（如果它已经在Git中）来实现。 （DONE）
- 修改您的Makefile。 您需要包括gdbstub源：如果Makefile的结构类似于Espressif示例中的文件，则可以将
gdbstub添加到SUBDIRS定义中，并将gdbstub/libgdbstub.a到COMPONENTS_eagle.app.v6定义中。 另外，您可能希望将-ggdb添加到编译器标志（TARGET_LDFLAGS）中，并且如果要调试，请将任何优化标志（-Os，-O2等）更改为-Og。 最后，确保您的Makefile也可以编译.S文件。
问题来了。 我没有SUBDIRS定义，但是我发现了
MODULES = mdns driver user
所以也许在这里最后我应该像这样添加gdbstub吗？
MODULES = mdns driver user gdbstub
我还没有找到COMPONENTS_eagle.app.v6东西，所以我不知道将gdbstub/libgdbstub.a放在gdbstub/libgdbstub.a 。 我在CFLAGS -ggdb （不是TARGET_LDFLAGS ），在CFLAGS也使用了-Os ，所以将其更改为-Og 。
- 通过编辑gdbstub-cfg.h来配置gdbstub。 您可以调整很多选项：FreeRTOS或裸SDK，私有异常/断点堆栈，控制台重定向到GDB，等到调试器附件等。您还可以通过在Makefile文件中包含适当的-Dwhatever gcc标志来配置这些选项。 （此文件未更改）
gdbstub-cfg.h：

(and related) can always be in flash, because it's called in the normal code flow. The rest of the
gdbstub functions can be in flash too, but only if there's no chance of them being called when the
flash somehow is disabled (eg during SPI operations or flash write/erase operations). If the routines
are called when the flash is disabled (eg due to a Ctrl-C at the wrong time), the ESP8266 will most
likely crash.

- 在您的user_main.c中，添加

您可以如下定义SUBDIR和COMPONENTS_eagle.app.v6（在Makefile中）。
COMPONENTS_eagle.app.v6
SUBDIRS = \\ gdbstub
COMPONENTS_eagle.app.v6 = \\ gdbstub / libgdbstub.a
编译错误
