再去交叉编译libcgi。
【折腾过程】
1.继续参考之前自己的：
【记录】cygwin下用arm-xscale-linux-gnueabi交叉编译libcgi
2.先拿到全新的源码：
crifan@ubuntu:libcgi-1.0$ pwd /home/crifan/develop/crosscompile/libcgi/libcgi-1.0 crifan@ubuntu:libcgi-1.0$ ls -lh total 104K -rwxrwxrwx 1 crifan root 58 Jan 20 2013 AUTHORS -rwxrwxrwx 1 crifan root 62 Jan 20 2013 autogen.sh -rwxrwxrwx 1 crifan root 204 Jan 20 2013 BUGS -rwxrwxrwx 1 crifan root 5.1K Jan 20 2013 ChangeLog -rwxrwxrwx 1 crifan root 44K Jan 20 2013 configure -rwxrwxrwx 1 crifan root 206 Jan 20 2013 configure.in drwxrwxrwx 4 crifan root 4.0K Aug 9 00:45 doc drwxrwxrwx 8 crifan root 4.0K Aug 9 00:45 examples -rwxrwxrwx 1 crifan root 4.7K Jan 20 2013 install-sh -rwxrwxrwx 1 crifan root 2.4K Jan 20 2013 Makefile.in -rwxrwxrwx 1 crifan root 613 Jan 20 2013 README drwxrwxrwx 2 crifan root 4.0K Aug 9 00:45 src -rwxrwxrwx 1 crifan root 645 Jan 20 2013 THANKS -rwxrwxrwx 1 crifan root 500 Jan 20 2013 TODO crifan@ubuntu:libcgi-1.0$
3.然后配置之前，去注意不要加CC，用如下配置：
crifan@ubuntu:libcgi-1.0$ mkdir /opt/crosscompile/libcgi crifan@ubuntu:libcgi-1.0$ ./configure --prefix=/opt/crosscompile/libcgi --build=i686-pc-linux-gnu --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi creating cache ./config.cache checking for gcc... gcc checking whether the C compiler (gcc ) works... yes checking whether the C compiler (gcc ) is a cross-compiler... no checking whether we are using GNU C... yes checking whether gcc accepts -g... yes checking for a BSD compatible install... /usr/bin/install -c checking how to run the C preprocessor... gcc -E checking for ANSI C header files... yes updating cache ./config.cache creating ./config.status creating Makefile creating src/config.h src/config.h is unchanged crifan@ubuntu:libcgi-1.0$
4.然后编译之前，参考：
去修改文件：
libcgi-1.0\src\string.c
中的587行的，从：
va_copy(bkp, str);
改为：
//va_copy(bkp, str); va_copy(bkp, ptr);
同时，之前已经对于prefix的目录，新建过了：
crifan@ubuntu:libcgi-1.0$ mkdir /opt/crosscompile/libcgi
所以，不用修改makefile，确保后期make install是OK的。
5.然后再去make，且加CC参数：
crifan@ubuntu: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 arm-xscale-linux-gnueabi-gcc -c -o src/string.o src/string.c arm-xscale-linux-gnueabi-gcc -c -o src/general.o src/general.c arm-xscale-linux-gnueabi-gcc -c -o src/list.o src/list.c arm-xscale-linux-gnueabi-gcc -c -o src/cookie.o src/cookie.c ar rc src/libcgi.a src/error.o src/cgi.o src/session.o src/base64.o src/md5.o src/string.o src/general.o src/list.o src/cookie.o arm-xscale-linux-gnueabi-gcc -shared -o src/libcgi.so src/error.o src/cgi.o src/session.o src/base64.o src/md5.o src/string.o src/general.o src/list.o src/cookie.o +---------------------------------------+ | Thanks for using LibCGI | +---------------------------------------+ | LibCGI is getting better because | | people like you are using it. So, if | | LibCGI is helping you in some way, | | please help us to improve it, sending | | suggestions, bug reports, bug fixes, | | and specially improvment code. | | You can subscribe to the mailing list | | or send a mail to the author. | +---------------------------------------+---------------------------+ | List: http://lists.sourceforge.net/lists/listinfo/libcgi-general | +-------------------------------------------------------------------+ crifan@ubuntu:libcgi-1.0$
6.然后去安装：
crifan@ubuntu:libcgi-1.0$ make install cp src/libcgi.a /opt/crosscompile/libcgi/lib cp src/libcgi.so /opt/crosscompile/libcgi/lib cp src/cgi.h /opt/crosscompile/libcgi/include cp src/session.h /opt/crosscompile/libcgi/include
再去确认一把，结果，还是很坑爹，是错的：
crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/ include lib crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/ -lh total 48K -rwxrwxr-x 1 crifan crifan 1.1K Aug 9 00:52 include -rw-rw-r-- 1 crifan crifan 44K Aug 9 00:52 lib crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/include -lh -rwxrwxr-x 1 crifan crifan 1.1K Aug 9 00:52 /opt/crosscompile/libcgi/include crifan@ubuntu:libcgi-1.0$
7.所以，继续去删除旧的，重新拷贝：
其中修改Makefile为：
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 $(INCDIR)
过程为：
crifan@ubuntu:libcgi-1.0$ rm /opt/crosscompile/libcgi/lib crifan@ubuntu:libcgi-1.0$ rm /opt/crosscompile/libcgi/include crifan@ubuntu:libcgi-1.0$ mkdir /opt/crosscompile/libcgi/inclue crifan@ubuntu:libcgi-1.0$ mkdir /opt/crosscompile/libcgi/lib crifan@ubuntu:libcgi-1.0$ make install cp src/libcgi.a /opt/crosscompile/libcgi/lib cp src/libcgi.so /opt/crosscompile/libcgi/lib cp src/cgi.h /opt/crosscompile/libcgi/include cp src/session.h /opt/crosscompile/libcgi/include crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/ -lh total 12K -rwxrwxr-x 1 crifan crifan 1.1K Aug 9 00:54 include drwxrwxr-x 2 crifan crifan 4.0K Aug 9 00:54 inclue drwxrwxr-x 2 crifan crifan 4.0K Aug 9 00:54 lib crifan@ubuntu:libcgi-1.0$ rm /opt/crosscompile/libcgi/include crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/ -lh total 8.0K drwxrwxr-x 2 crifan crifan 4.0K Aug 9 00:54 inclue drwxrwxr-x 2 crifan crifan 4.0K Aug 9 00:54 lib crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/lib/ -lh total 88K -rw-rw-r-- 1 crifan crifan 43K Aug 9 00:54 libcgi.a -rwxrwxr-x 1 crifan crifan 44K Aug 9 00:54 libcgi.so crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/inclue/ -lh total 0 crifan@ubuntu:libcgi-1.0$ gedit Makefile crifan@ubuntu:libcgi-1.0$ make install mkdir -p /opt/crosscompile/libcgi/lib cp src/libcgi.a /opt/crosscompile/libcgi/lib cp src/libcgi.so /opt/crosscompile/libcgi/lib mkdir -p /opt/crosscompile/libcgi/include cp src/cgi.h /opt/crosscompile/libcgi/include cp src/session.h /opt/crosscompile/libcgi/include crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/ -lh total 12K drwxrwxr-x 2 crifan crifan 4.0K Aug 9 00:57 include drwxrwxr-x 2 crifan crifan 4.0K Aug 9 00:54 inclue drwxrwxr-x 2 crifan crifan 4.0K Aug 9 00:54 lib crifan@ubuntu:libcgi-1.0$ rm /opt/crosscompile/libcgi/inclue -fR
8.最后验证才是对的：
crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/ -lh total 8.0K drwxrwxr-x 2 crifan crifan 4.0K Aug 9 00:57 include drwxrwxr-x 2 crifan crifan 4.0K Aug 9 00:54 lib crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/include/ -lh total 12K -rwxrwxr-x 1 crifan crifan 4.3K Aug 9 00:57 cgi.h -rwxrwxr-x 1 crifan crifan 1.1K Aug 9 00:57 session.h crifan@ubuntu:libcgi-1.0$ ls /opt/crosscompile/libcgi/lib -lh total 88K -rw-rw-r-- 1 crifan crifan 43K Aug 9 00:57 libcgi.a -rwxrwxr-x 1 crifan crifan 44K Aug 9 00:57 libcgi.so crifan@ubuntu:libcgi-1.0$
【总结】
在Ubuntu下，交叉编译libcgi：
准备工作：
1. 去修改文件：
libcgi-1.0\src\string.c
中的587行的，从：
va_copy(bkp, str);
改为：
//va_copy(bkp, str); va_copy(bkp, ptr);
以此避免：
2.去修改Makefile
从：
install: cp src/libcgi.a $(LIBDIR) cp src/libcgi.so $(LIBDIR) cp src/cgi.h $(INCDIR) cp src/session.h $(INCDIR)
变为：
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)
以此避免：
后面make install时，会误将要安装的文件，不是拷贝到include和lib目录，而是拷贝成include和lib两个文件了。
过程：
1.配置：
./configure --prefix=/opt/crosscompile/libcgi --build=i686-pc-linux-gnu --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi
2.编译：
make CC=arm-xscale-linux-gnueabi-gcc
3.安装：
make install
