标题: winAVR编译出错”../Obj/ST7735/RvalOut.o: In function' RvalOut':additional rel...
最近在复刻一个经典开源项目用atmega328制作的晶体管测试仪，立创上好几个版本比如这个oshwhubcom/micespring/m328-transistor-tester。制作也成功了，使用其他人的固件。
可是当我想使用源程序自己编译的时候总是无法成功，更别提要修改makefile来实现我想要的效果了。
我用的是在虚拟机里的WINAVR 2010编译的，编译的时候总是会出现
”../Obj/ST7735/RvalOut.o: In function' RvalOut':additional relocation overflows omitted from the output
make.exe: ***[../obj/ST7735/ST7735.elf] Error 1"
的错误。源程序是在GitHub上下的，网上似乎没人和我一样出现这个报错，各个开源作者也都可以自己编译，系统也换了好几个，实在搞不懂哪里出问题，研究了好久，有没有大佬可以指点一二，本人只是小爱好，但这个问题没解决真的很难受。

还是说我用的这个makefile文件不对

# The WITH_MENU option enables a dialog to choose some additional functions.
# Currently a frequency measurement at ATmega Pin PD4, a frequency generator at TP2 ,
# the external voltage measurement and C+ESR measurement can be selected. Of course you can also return to
# the normal transistor tester function and switch off the tester.

# The menu function can be easier controlled with a incremental encoder (rotary switch).
# Both switches of the rotary switch can be connected with 1 kOhm resistors to PD1 and PD3.
# The common contact of the two switches must be connected to GND.
# You must also connect both switch contacts with two 10 kOhm resistors to VCC (pull up).

# parallel to the start key of the Transistor Tester.

# If your encoder has the same count of pulses at any switch as indexed positions (detent) for every turn,
# you should set the WITH_ROTARY_SWITCH to 2 or 3.
# If your encoder has twice the count of indexed positions, you should set the WITH_ROTARY_COUNT to 1.
# For rotary encoder without indexed position or with an indexed position at every change of
# the state of any switches (four times the count of pulses) you can set the
# WITH_ROTARY_COUNT to 5 for getting the best resolution.
# You can also use two separate push-buttons for Up and Down instead ot the rotary encoder.

感谢回复！makefile文件里PARTNO = m328p，目标芯片应该没问题吧，毕竟别人都可以。
开大optim等级是什么意思开源项目的编译教程用的就是winAVR这个软件，软件似乎没有什么编译选项，也没有哪里可以选择目标芯片。
我是照着教程打开makefile文件，先make clean，然后make all。我不理解为什么同个程序同个软件无法编译。

开大optim等级是什 ...

-O3 编译出来的代码最小，但是avr-gcc我用过-O3有严重bug，可能出来一堆乱七八糟的不知所云的东西。-O2一定靠谱，你试试。

-O3一般会有问题。-O2或-Os可以。
