뒤척이다
[기록] 교차 컴파일러arm-xscale-linux-gnueabi로 끼워넣는 리눅스 기반 무선HART 프로젝트를 교차 컴파일합니다
이 경우 include 경로에는 다음이 표시됩니다.
-I xxx/armxscalelibcgi/include
따라서 라이브러리libcgi가 필요합니다.
여기에는 이미 소스가 있습니다.libcgi-1.0
[뒤척이는 과정]
1. 먼저 코드와 설정을 살펴보자.

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ ls

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ ./configure --help

2. 직접 구성:

./configure --prefix=$HOME/develop/crosstool-ng/x-tools/libcgi --build=i686-pc-cygwin --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi CC=arm-xscale-linux-gnueabi-gcc

결과적으로 CC는 지원되지 않습니다.

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ ./configure --prefix=$HOME/develop/crosstool-ng/x-tools/libcgi --build=i686-pc-cygwin --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi CC=arm-xscale-linux-gnueabi-gcc
configure: warning: CC=arm-xscale-linux-gnueabi-gcc: invalid host type

3.그러니 CC를 빼라:

./configure --prefix=$HOME/develop/crosstool-ng/x-tools/libcgi --build=i686-pc-cygwin --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi

테스트:

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ ./configure --prefix=$HOME/develop/crosstool-ng/x-tools/libcgi --build=i686-pc-cygwin --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi

4. 그리고 다시 make로 컴파일하기:

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ make
cc    -c -o src/error.o src/error.c
cc    -c -o src/cgi.o src/cgi.c

뚜렷하다
5. 가봤더니..o, x86의 것일 뿐,arm의 것이 아닙니다:

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ file src/
base64.c     cgi.c        cgi.o        config.h.in  cookie.o     error.h      general.c    libcgi.a     list.c       md5.c        session.c    session.o    string.o

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ file src/cgi.o
src/cgi.o: 80386 COFF executable not stripped - version 30821

6. 참조:
How to libcgi?
그리고 보러 갔어요.
libcgi-1.0\Makefile
구문을 사용합니다.

.c.o: $(CC) $(FLAGS) -c $<

그래서 다시 설정해 보세요.

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ ./configure --prefix=$HOME/develop/crosstool-ng/x-tools/libcgi --build=i686-pc-cygwin --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi

7. 그 다음 make 시 CC 매개 변수 추가

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ make CC=arm-xscale-linux-gnueabi-gcc

결과적으로 다시 컴파일할 것이 없습니다.

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ make CC=arm-xscale-linux-gnueabi-gcc

8. 그래서 클렌징에 가서:

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ make clean
find src/ -name *.*o -exec rm -f {} \; find src/ -name *.a -exec rm -f {} \;

재구성:

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ ./configure --prefix=$HOME/develop/crosstool-ng/x-tools/libcgi --build=i686-pc-cygwin --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi

make + CC 를 교차 컴파일할 수 있습니다.

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ make CC=arm-xscale-linux-gnueabi-gcc
arm-xscale-linux-gnueabi-gcc    -c -o src/error.o src/error.c
arm-xscale-linux-gnueabi-gcc    -c -o src/cgi.o src/cgi.c
arm-xscale-linux-gnueabi-gcc    -c -o src/session.o src/session.c
arm-xscale-linux-gnueabi-gcc    -c -o src/base64.o src/base64.c
arm-xscale-linux-gnueabi-gcc    -c -o src/md5.o src/md5.c

9.그런데 결과가 틀렸어요.
[해결됨]cygwin에서arm-xscale-linux-gnueabi로 교차 컴파일libcgi 오류:src/string.c:587:2: error: incompatible type for argument 2 of ‘__builtin_va_copy’
10.make는 번역이 끝났습니다.
지금 가서 설치를 시도해 보세요.

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ make install
cp src/libcgi.a /home/CLi/develop/crosstool-ng/x-tools/libcgi/lib
cp src/libcgi.so /home/CLi/develop/crosstool-ng/x-tools/libcgi/lib
cp src/cgi.h /home/CLi/develop/crosstool-ng/x-tools/libcgi/include
cp src/session.h /home/CLi/develop/crosstool-ng/x-tools/libcgi/include

11. OK인 줄 알았는데 갑자기 아버지의 발견으로 설치 디렉터리에 있는lib와include는 폴더가 아닌 파일이었다.

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ ll /home/CLi/develop/crosstool-ng/x-tools/libcgi

-rwxr-xr-x 1 CLi Domänen-Benutzer 1.1K Aug  6 12:59 include*
-rw-r--r-- 1 CLi Domänen-Benutzer  44K Aug  6 12:59 lib

따라서 이 두 파일을 삭제하고 새 두 폴더를 만들고 수동으로 다시 복사해 보십시오.

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ rm /home/CLi/develop/crosstool-ng/x-tools/libcgi/*

CLi@PC-CLI-1 ~/develop/libcgi/libcgi-1.0
$ ll /home/CLi/develop/crosstool-ng/x-tools/libcgi

$ mkdir /home/CLi/develop/crosstool-ng/x-tools/libcgi/lib

이렇게 해야만 성공한 셈이다.
대응하는 것이 생겼다.a와.so의 창고, 대응하는 것이 있습니다.h 파일.
->
분명히 makefile가 잘못 썼어요.
12. 엎치락뒤치락 테스트 결과,makefile은 원래부터:

install:
  cp src/libcgi.a $(LIBDIR)
 cp src/libcgi.so $(LIBDIR)  cp src/cgi.h $(INCDIR)  cp src/session.h $(INCDIR)

다음으로 변경:

install:
  mkdir -p $(LIBDIR)
  cp src/libcgi.a $(LIBDIR)
 cp src/libcgi.so $(LIBDIR)  mkdir -p $(INCDIR)  cp src/cgi.h $(INCDIR)  cp src/session.h $(INCDIR)

됐어요.
여기에서:
(1) 대응하는 uninstall 부분은 관여하지 않았다.
(2)makefile 파일도 configure에서 생성된 것이기 때문에 최종 수정은 configure 파일을 수정하는 것입니다.이곳이 익숙하지 않으니 잠시 깊이 연구하지 않겠다.
효과:

【총괄】
이 절차는 다음과 같습니다.
1. 구성:

./configure --prefix=$HOME/develop/crosstool-ng/x-tools/libcgi --build=i686-pc-cygwin --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi

주: 여기에서 CC를 지정하면 식별할 수 없기 때문에 CC의 지정은make 뒤에 있습니다.
2. 컴파일링:
준비:
(1) 수정:
libcgi-1.0\src\string.c
의 587 행:

va_copy(bkp, str);

다음으로 변경:

//va_copy(bkp, str);
va_copy(bkp, ptr);

컴파일링:
CC를 지정하고 make로 컴파일하기

make CC=arm-xscale-linux-gnueabi-gcc

3. 설치:
준비:
makefile에서 다음을 수행합니다.

install:
  cp src/libcgi.a $(LIBDIR)
 cp src/libcgi.so $(LIBDIR)  cp src/cgi.h $(INCDIR)  cp src/session.h $(INCDIR)

다음으로 변경:

install:
  mkdir -p $(LIBDIR)
  cp src/libcgi.a $(LIBDIR)
 cp src/libcgi.so $(LIBDIR)  mkdir -p $(INCDIR)  cp src/cgi.h $(INCDIR)  cp src/session.h $(INCDIR)

됐어요.
설치:

make install
