交叉编译 libzdb
参考博客：移植libzdb3.2.2到arm_configure: error: no available database found or s_酣楼驻海的博客-CSDN博客
编译时间 2023-08-23
libzdb 下载：
源码访问如下：
https://bitbucket.org/tildeslash/libzdb/src/master/git 下载链接
git clone https://bitbucket.org/tildeslash/libzdb.git我将其同步到了 gitee，然后从 gitee 上下载的；
编译环境：
使用 ubuntu 18.04 版本；
在以下链接下载了 arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-linux-gnueabihf 交叉编译器；
https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads编译：
1.源码下载后文件内容如下：

#include
#include
jmp_buf jump_buffer;
void test_jump() {
longjmp(jump_buffer, 1);
}
int main() {
if (setjmp(jump_buffer) == 0) {
printf("Calling test_jump()\n");
test_jump();
} else {
printf("Back from test_jump()\n");
}
return 0;
} 4.使用新的命令编译，遇到问题2

va_end(args);
printf("%s", buffer);
}
int main() {
custom_printf("Hello %s, you have %d messages.\n", "Alice", 5);
return 0;
}
5.使用新的命令编译，遇到问题3
libzdb_cv_setjmp_available=yes libzdb_cv_vsnprintf_c11_conformant=yes ./configure --host=arm-none-linux-gnueabihf问题3：configure: error: No available database found or selected. Try configure --help

configure: error: No available database found or selected. Try configure --help需要指定数据库，使用了 --with-sqlite
6.使用新的命令编译，遇到问题4
libzdb_cv_setjmp_available=yes libzdb_cv_vsnprintf_c11_conformant=yes ./configure --host=arm-none-linux-gnueabihf --with-sqlite问题4：configure: error: cannot check for file existence when cross compiling

checking for yes... configure: error: cannot check for file existence when cross compiling
修改 configure 文件，将含有 "cannot check for file existence when cross compiling" 的行给注释掉，我一共注释了三行；
7.继续编译，遇到问题5
libzdb_cv_setjmp_available=yes libzdb_cv_vsnprintf_c11_conformant=yes ./configure --host=arm-none-linux-gnueabihf --with-sqlite问题5：configure: error: No available database found or selected. Try configure --help

...............................
configure: WARNING: pg_config is required to build libzdb with postgresql

checking for mysql... yes
checking for mysql_config... no
configure: WARNING: mysql_config is required to build libzdb with mysql
checking for oracle... checking if Oracle support is enabled... no
configure: error: No available database found or selected. Try configure --help需要指定 sqlite3 库的路径，文件放置如下：
user:sqlite3_bin$tree
.
├── include
│ └── sqlite3.h
└── lib
├── libsqlite3.so -> libsqlite3.so.0.8.6
├── libsqlite3.so.0 -> libsqlite3.so.0.8.6
└── libsqlite3.so.0.8.6
修改 --with-sqlite 为 --with-sqlite=/opt/liangtao/libs/sqlite3_bin/
8. 使用新命令编译，配置成功
libzdb_cv_setjmp_available=yes libzdb_cv_vsnprintf_c11_conformant=yes ./configure --host=arm-none-linux-gnueabihf --with-sqlite=/opt/liangtao/libs/sqlite3_bin/
9. 直接 make 遇到问题 6
问题6：./tools/bin/filterh < src/zdb.h > zdb/zdb.h || exit 1
user:libzdb$make
./tools/bin/filterh < src/zdb.h > zdb/zdb.h || exit 1
/lib/ld-linux-armhf.so.3: No such file or directory
Makefile:1248: recipe for target 'zdb/zdb.h' failed
make: *** [zdb/zdb.h] Error 1
user:libzdb$
由于 filterh 是 arm 格式的，所以遇到该问题；
解决方法：重新下载一份源码，在源码顶层目录，直接运行以下命令，报错不用处理；
./bootstrap && ./configure将 x86 的 ./tools/bin/filterh 替换交叉编译器相同的目录下的 filterh 文件；
user:libtmp$ls -al ./tools/bin/filterh
-rwxrwxr-x 1 vmuser vmuser 23568 Aug 23 16:15 ./tools/bin/filterh

10. 继续编译遇到问题 7
问题7：re2c: error: line 201, column 22: unrecognized configuration 'eof'

将文件 src/system/Time.re line 201 删除
11.继续编译遇到问题 8

re2c: error: line 211, column 17: unexpected character: '$'接着将报错的行删除；
总的修改后 src/system/Time.re 文件如下：

12. 继续编译，后面遇到链接报错，没有在意，因为库文件已经编出；
