BSEC 库 Arduino 的问题
Issues with BSEC Library Arduino
我只想让库在 Arduino IDE 1.8.13 中工作。但是，它总是无法编译。
我已经调整了 platform.txt，但是它没有做任何事情。我已经从 github (https://github.com/BoschSensortec/BSEC-Arduino-library) 下载了库。
用 ESP32 开发板编译时总是返回同样的错误。
我的错误在哪里？
调试代码如下：

如果您对 platform.txt 文件进行正确修改，Arduino IDE 1.8.13 将找到该库。我的文件位于此处：
C:\Users\(username)\AppData\Local\Arduino15\packages\esp32\hardware\esp32.0.6\platform.txt
首先确保您的 platform.txt 文件中有一般更改。也就是说，您定义了 compiler.libraries.ldflags。我的 platform.txt 已经将其定义为空，compiler.libraries.ldflags=。如果您的尚未定义，请将该行添加到 platform.txt 文件中的某处。
接下来，你要引用它。您可以按照 ESP8266 的说明进行操作。更改以下内容：
recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" {compiler.c.elf.flags} {compiler.c.elf.extra_flags} {compiler.libraries.ldflags} -Wl,--start-group {object_files} "{archive_file_path}" {compiler.c.elf.libs} {build.extra_libs} -Wl,--end-group -Wl,-EL -o "{build.path}/{build.project_name}.elf"
为此：
recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" {compiler.c.elf.flags} {compiler.c.elf.extra_flags} {compiler.libraries.ldflags} -Wl,--start-group {object_files} "{archive_file_path}" {compiler.c.elf.libs} {compiler.libraries.ldflags} {build.extra_libs} -Wl,--end-group -Wl,-EL -o "{build.path}/{build.project_name}.elf"
注意最后一次出现 compiler.libraries.ldflags。我上面显示的文本与 github 文档中显示的文本不完全匹配。我只是在 --start-group 指令之后添加了 compiler.libraries.ldflags，这就是 github 文档显示的内容。
一旦我这样做，保存文件，并重新启动 Arduino，它全部编译和链接成功。
