c++ - 无法在 Windows 上编译 SQLCipher

Question

我正在尝试编译 SQLCipher。我已经从http://sqlcipher.net/下载了源代码。 然后我从这篇文章中做: [http://groups.google.com/group/sqlcipher/browse_thread/thread/55c6296b56bf4533:][1]

[1] 我安装了 MinGW(将路径设置为 gcc:d:\MinGW\bin)、OpenSSL 和 ActiveState Perl。我将文件 libeay32.dll 复制到 sqlcipher 目录。然后我尝试执行这个命令:

./configure --disable-tcl CFLAGS="-DSQLITE_HAS_CODEC
-I/path/to/openssl/include" LDFLAGS="-leay32"

我得到了错误:

checking build system type... i686-pc-mingw32
checking host system type... i686-pc-mingw32
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See 'config.log' for more details.

Config.log 显示:

configure:2537: $? = 0
configure:2544: gcc -v >&5
Using built-in specs.

我不知道什么是-leay32。我将文件 libeay32.dll 复制到 sqlcipher 目录。在D中有目录OpenSSL-Win32。

谢谢

尝试一下您的配置命令:

./configure –disable-tcl CFLAGS=”-DSQLITE_HAS_CODEC –Ic:/path/to/openssl/include –Lc:/path/to/openssl/lib –leay32”

-leay32 是一个库标志，因此可以将其想象为“-l eay32”。它被称为“eay32”，因为库标志忽略“libeay32”的“lib”。
