오류 : -march = 스위치의 값이 잘못되었습니다.

Question

Makefile을 작성했는데 제대로 작동하지 않습니다. 내가 컴파일 할 프로세서를 선택해야하는 옵션이 있습니다.

tandex@tandex-P-6860FX:~/emulators/nintendo sdks/3DS SDK [HomeBrew]$ make 
gcc -march=arm7tdmi -static -fexceptions -fnon-call-exceptions -fstack-check test.c -c 
test.c:1:0: error: bad value (arm7tdmi) for -march= switch 

make: *** [ALL] Error 1 

을하지만 GCC에 대한 매뉴얼 페이지에서, 그것은 ARM7TDMI가 허용 값입니다 상태 : 그러나 내가 명령 줄에서 make을 실행할 때, 그것은 말했다. 내가 놓친 게 있니?

메이크 : 당신은 아마 권리의 gcc를 호출하지 않는

Answer 1

. 3DS SDK와 함께 제공되는 gcc 대신 시스템에 gcc가 설치되어있는 것 같습니다.

Answer 2

문제가 -march=arm7tdmi 인 것으로 보입니다.

해결 방법은 -march=arm7tdmi을 사용하지 않는 것이 좋습니다. -march=cpu-type을 사용하십시오. 여기서 cpu-type은 GCC 설명서의 3.17.4 ARM Options에 나열된 것 중 하나입니다.

-march=name

This specifies the name of the target ARM architecture. GCC uses this name to determine what kind of instructions it can emit when generating assembly code. This option can be used in conjunction with or instead of the -mcpu= option. Permissible names are: ‘armv2’, ‘armv2a’, ‘armv3’, ‘armv3m’, ‘armv4’, ‘armv4t’, ‘armv5’, ‘armv5t’, ‘armv5e’, ‘armv5te’, ‘armv6’, ‘armv6j’, ‘armv6t2’, ‘armv6z’, ‘armv6kz’, ‘armv6-m’, ‘armv7’, ‘armv7-a’, ‘armv7-r’, ‘armv7-m’, ‘armv7e-m’, ‘armv7ve’, ‘armv8-a’, ‘armv8-a+crc’, ‘iwmmxt’, ‘iwmmxt2’, ‘ep9312’.
