[align=left][font=Arial, Helvetica, sans-serif][size=12px]在DSP28335中，用的是CCS6.2，在main.c中首先包含了math.h，如下：[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px][img=0,240]https://e2echina.ti.com/resized-image/__size/640x480/__key/communityserver-components-multipleuploadfilemanager/ce4c46aa_2D00_a133_2D00_464f_2D00_9d6b_2D00_3630b2ccaa04-154057-complete/pastedimage1726107940466v1.png[/img]，[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px]然后在main.c中，调用sin，cos，atan，mod等函数都可以正常编译并使用，但是当调用trunc取整函数的时候编译报错，取整类函数ceil也不能使用，报错，如下：[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px][img=0,240]https://e2echina.ti.com/resized-image/__size/640x480/__key/communityserver-components-multipleuploadfilemanager/ce4c46aa_2D00_a133_2D00_464f_2D00_9d6b_2D00_3630b2ccaa04-154057-complete/pastedimage1726108090161v2.png[/img]，[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px][img=0,240]https://e2echina.ti.com/resized-image/__size/640x480/__key/communityserver-components-multipleuploadfilemanager/ce4c46aa_2D00_a133_2D00_464f_2D00_9d6b_2D00_3630b2ccaa04-154057-complete/pastedimage1726108126944v3.png[/img]，[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px]然后我的具体调用如下，并更换了多种形式，仍然报错，只要把trunc函数换了就不报错了，[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px][img=0,240]https://e2echina.ti.com/resized-image/__size/640x480/__key/communityserver-components-multipleuploadfilemanager/ce4c46aa_2D00_a133_2D00_464f_2D00_9d6b_2D00_3630b2ccaa04-154057-complete/pastedimage1726108235827v4.png[/img][/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px]我检查了math.h中是否包含了trunc，确认包含了，[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px][img=0,240]https://e2echina.ti.com/resized-image/__size/640x480/__key/communityserver-components-multipleuploadfilemanager/ce4c46aa_2D00_a133_2D00_464f_2D00_9d6b_2D00_3630b2ccaa04-154057-complete/pastedimage1726108337401v5.png[/img]，[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px]然后math.h调用以及文件所在是安装ccs时候默认的，如下：[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px][img=0,240]https://e2echina.ti.com/resized-image/__size/640x480/__key/communityserver-components-multipleuploadfilemanager/ce4c46aa_2D00_a133_2D00_464f_2D00_9d6b_2D00_3630b2ccaa04-154057-complete/pastedimage1726108452046v8.png[/img]，[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px]里面包含了math.h，然后我在lib中配置如下：[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px][img=0,240]https://e2echina.ti.com/resized-image/__size/640x480/__key/communityserver-components-multipleuploadfilemanager/ce4c46aa_2D00_a133_2D00_464f_2D00_9d6b_2D00_3630b2ccaa04-154057-complete/pastedimage1726108520352v9.png[/img]。[/size][/font][/align][align=left][font=Arial, Helvetica, sans-serif][size=12px]请教大佬和专业工程师，我这报错，不能编译是什么原因？[/size][/font][/align]

目前项目需要在linux下把C编译成hex(适配PIC内核)，只需要编译环境，目前自己尝试了下载Linux版本MPLAB IDE加 XC8 C编译器，发现是需要额外安装JRE，使用MPLAB IDE环境才能编译成hex，能否不用IDE环境将C编译成hex，有大佬了解过这块吗
