標題: winAVR編譯出錯”../Obj/ST7735/RvalOut.o: In function' RvalOut':additional rel...
最近在復刻一個經典開源項目用atmega328制作的晶體管測試儀，立創上好幾個版本比如這個oshwhubcom/micespring/m328-transistor-tester。制作也成功了，使用其他人的固件。
可是當我想使用源程序自己編譯的時候總是無法成功，更別提要修改makefile來實現我想要的效果了。
我用的是在虛擬機里的WINAVR 2010編譯的，編譯的時候總是會出現
”../Obj/ST7735/RvalOut.o: In function' RvalOut':additional relocation overflows omitted from the output
make.exe: ***[../obj/ST7735/ST7735.elf] Error 1"
的錯誤。源程序是在GitHub上下的，網上似乎沒人和我一樣出現這個報錯，各個開源作者也都可以自己編譯，系統也換了好幾個，實在搞不懂哪里出問題，研究了好久，有沒有大佬可以指點一二，本人只是小愛好，但這個問題沒解決真的很難受。

還是說我用的這個makefile文件不對

# The WITH_MENU option enables a dialog to choose some additional functions.

# 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 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.

感謝回復！makefile文件里PARTNO = m328p，目標芯片應該沒問題吧，畢竟別人都可以。
開大optim等級是什么意思

開源項目的編譯教程用的就是winAVR這個軟件，軟件似乎沒有什么編譯選項，也沒有哪里可以選擇目標芯片。
我是照著教程打開makefile文件，先make clean，然后make all。我不理解為什么同個程序同個軟件無法編譯。

開大optim等級是什 ...

-O3 編譯出來的代碼最小，但是avr-gcc我用過-O3有嚴重bug，可能出來一堆亂七八糟的不知所云的東西。-O2一定靠譜，你試試。

作者: pluto1000 時間: 2023-12-31 21:45
-O3一般會有問題。-O2或-Os可以。
