arm-none-linux-gnueabi-gcc 컴파일 표준 라이브러리 인용

arm-none-linux-gnueabi-gcc로 컴파일할 때 표준 라이브러리에서 찾을 수 없는 상황이 발생합니다.예:
[root@localhost wpcode]# arm-none-linux-gnueabi-gcc *.c -fPIC -shared -o libsdk.so  opensslRsa.c:3:30: error: openssl/ossl_typ.h: No such file or directory opensslRsa.c:4:25: error: openssl/pem.h: No such file or directory opensslRsa.c:5:26: error: openssl/x509.h: No such file or directory opensslRsa.c:6:25: error: openssl/rsa.h: No such file or directory opensslRsa.c:8:26: error: openssl/des.h: No such file or directory
 
해결 방법:

[root@localhost wpcode]# echo 'main(){}'|arm-linux-gcc -E -v - 
bash: arm-linux-gcc:  ...
[root@localhost wpcode]# echo 'main(){}'|arm-none-linux-gnueabi-gcc -E -V -
arm-none-linux-gnueabi-gcc: '-V' must come at the start of the command line
[root@localhost wpcode]# echo 'main(){}'|arm-none-linux-gnueabi-gcc -E -v -
