怎么使用免费工具链为STM8l152编译Spirit1库？

嗨，

使用-pc99命令行开关可以支持Cosmic编译器中的大多数C99功能：如果这还不够，请发布您得到的错误，我们将看到我们可以做什么。

问候，

卢卡

Hi,

using the -pc99 command line switch enables support of most of the C99 features in the Cosmic compiler: if this is not enough please post the error you get and we will see what we can do.

Regards,

Luca

谢谢卢卡，


使用-pc99，我得到了一些使用Cosmic编译的错误。

Spirit1库中的以下文件和示例STM8实现在for循环中声明变量（即''for（int i =（cDataLength-1）; i＆gt; = 0; i--）''），Cosmic编译器不处理：
SPIRIT_Aes.c
SPIRIT_Irq.c
SPIRIT_PktBasic.c
SPIRIT_pktcommon.c
SPIRIT_pktstack.c
SPIRIT_radio.c

SDK_EVAL_Gpio.c
SDK_EVAL_Spi_Driver.c

我将那些声明移到了满足编译器的for语句之外。这会改变这些变量的范围并可能导致问题，因为大多数这些函数都重用变量“i”。

在链接期间，我也会收到以下符号未定义的错误：
#error clnk Debug spirit1_lib.lkf：1个符号_lroundf未定义（Debug spirit_radio.o）
#error clnk Debug spirit1_lib.lkf：1个符号_pow未定义（Debug spirit_radio.o）
#error clnk Debug spirit1_lib.lkf：未定义1个符号_log2（Debug spirit_radio.o）
#error clnk Debug spirit1_lib.lkf：1个符号_round未定义（Debug spirit_radio.o）

我认为这些是c99中的标准数学函数。我在IAR＆lt; math.h＆gt;中看到对它们的引用。标题，但看起来它们从Cosmic＆lt; math.h＆gt;中丢失了头。你知道一个解决方法吗？

感谢您的帮助，
-大卫

Thanks Luca,


With -pc99 the I get some errors compiling with Cosmic.

The following files in the Spirit1 library and example STM8 implementation declare variables in for loops (i.e. ''for(int i = (cDataLength-1); i>=0; i--)''), which the Cosmic compiler does not handle:
SPIRIT_Aes.c
SPIRIT_Irq.c
SPIRIT_PktBasic.c
SPIRIT_pktcommon.c
SPIRIT_pktstack.c
SPIRIT_radio.c

SDK_EVAL_Gpio.c
SDK_EVAL_Spi_Driver.c

I moved those declarations outside of the for statements which satisfies the compiler. This changes the scope of those variables and could cause issues since most of those functions reuse the variable ''i''.

During linking I also get errors that the following symbols are not defined:
#error clnk Debugspirit1_lib.lkf:1 symbol _lroundf not defined (Debugspirit_radio.o )
#error clnk Debugspirit1_lib.lkf:1 symbol _pow not defined (Debugspirit_radio.o )
#error clnk Debugspirit1_lib.lkf:1 symbol _log2 not defined (Debugspirit_radio.o )
#error clnk Debugspirit1_lib.lkf:1 symbol _round not defined (Debugspirit_radio.o )

I think these are standard math functions in c99. I see references to them in the IAR header, but it looks like they are missing from the Cosmic header. Do you know a workaround for this?

Thank you for the help,
-David

你好，
我确认不支持for循环中的变量声明。
至于链接器阶段的缺失符号，您提到的4个中的3个已经被支持（确保链接文件中的libf），第四个（lroundf（））将在下一个版本中添加。
问候，
卢卡



以下为原文




Hello,
I confirm that the variable declaration in the for loop is not supported.
As for the missing symbols at the linker stage, 3 out of the 4 that you mention are already supported (make sure you link the libf in the linker file) and the fourth (lroundf()) will be added in the next release.
Regards,
Luca

您可能希望查看SDCC的当前开发版本而不是3.6.0版本。支持在3.6.0版本之后添加到SDCC的for循环中的变量声明。所以当前的开发版本（以及未来的3.7.0版本）都有它。

You might want to check with a current development version of SDCC instead of the 3.6.0 release. Support for variable declarations in for loops as been added to SDCC after the 3.6.0 release. So current development versions (and the future 3.7.0 release) have it.
