[英]Cannot cross-compile cURL with OpenSSL support for Windows
我正在尝试从 Linux (Debian Jessie) 为 Windows 进行交叉编译。 我已经编译了zlib
和OpenSSL
并且 cURL 的配置脚本确实找到了这些库,但是它仍然说 SSL 支持已关闭。
这是我使用的构建脚本:
# ZLIB
cd /builds
curl -O -J http://www.zlib.net/zlib-1.2.11.tar.gz
tar xf zlib-1.2.11.tar.gz
cd /builds/zlib-1.2.11
CC=x86_64-w64-mingw32-gcc ./configure --prefix=/usr/x86_64-w64-mingw32 --static
make && make install
# OPENSSL
cd /builds
curl -O -J https://www.openssl.org/source/openssl-1.1.0c.tar.gz
tar xf openssl-1.1.0c.tar.gz
cd /builds/openssl-1.1.0c
CROSS_COMPILE="x86_64-w64-mingw32-" ./Configure -DHAVE_STRUCT_TIMESPEC -lz -lws2_32 zlib mingw64 no-shared --prefix=/usr/x86_64-w64-mingw32
make depend
make && make install
# CURL
cd /builds
curl -O -J https://curl.haxx.se/download/curl-7.52.1.tar.gz
cd /builds/curl-7.52.1
./configure --prefix=/usr/x86_64-w64-mingw32 --host=x86_64-w64-mingw32 --enable-optimize --with-ssl=/usr/x86_64-w64-mingw32
它成功找到了该库,但由于缺少--with-ssl
SSL 刚刚被禁用

为了使用 ssl 支持交叉编译 curl,我直接在CPP_FLAGS
和LD_FLAGS
提供了位置,而不是使用--with-ssl
提供路径:
export DESTDIR="$CURL_INSTALL_DIR"
export CPPFLAGS="-I${OPENSSL_INSTALL_DIR}/include -I${ZLIB_INSTALL_DIR}/include"
export LDFLAGS="-L${OPENSSL_INSTALL_DIR}/lib -L${ZLIB_INSTALL_DIR}/lib"
export LIBS="-lssl -lcrypto"
CURL_ARGS="--with-ssl --with-zlib --disable-ftp --disable-gopher
--disable-file --disable-imap --disable-ldap --disable-ldaps
--disable-pop3 --disable-proxy --disable-rtsp --disable-smtp
--disable-telnet --disable-tftp --without-gnutls --without-libidn
--without-librtmp --disable-dict"
chmod 777 buildconf
./buildconf
./configure --host="${CROSS_COMPILE}" $CURL_ARGS
make -j16
make install
检查这个curl 交叉编译脚本
我也花了整整一周的时间才为 cURL 启用 SSL。 从您的配置日志中,您需要将这两行启用为yes
checking for HMAC_Update in -lcrypto... no
checking for HMAC_Init_ex in -lcrypto... no
问题在于 OpenSSL 的构建方式。 就我而言,我通过添加-fPIC -ldl
构建了 OpenSSL,如下所示
#For OpenSSL 1.0.2s
export USING_OPENSSL=./openssl-1.0.2s
export CROSS_COMPILE_PREFIX=mips-unknown-linux-uclibc-
export SSL_OPTIONS="enable-ssl-trace enable-shared enable-ssl enable-ssl2 enable-ssl3 enable-ssl3-method enable-
tls enable-tls1_1 enable-tls1_2 enable-weak-ssl-ciphers enable-unit-test enable-async enable-md2"
cd $USING_OPENSSL && CC=gcc AR=ar RANLIB=ranlib LD=ld ./Configure linux-mips32 -fPIC -ldl --openssldir=$USING_OPENSSL/OPSSL --prefix=$USING_OP
ENSSL/OPSSL --cross-compile-prefix=$CROSS_COMPILE_PREFIX $SSL_OPTIONS
make -C $USING_OPENSSL;
make install -C $USING_OPENSSL;
如果链接器undefined reference to 'TLS_DTPREL_VALUE'
有错误,请参阅链接https://codeleading.com/article/82492718270/ ,链接上的修复程序可能不适用于您的 OpenSSL,您必须将其修改为适合您的 OpenSSL 版本。
使用我的 OpenSSL 1.0.2s,构建目标是不同的,所以需要修改如下:
@echo Patch Makefile
sed -i -e 's/build_all:.*/build_all: build_libs/g' $USING_OPENSSL/Makefile
sed -i -e 's/build_libs:.*/build_libs: build_libcrypto build_libssl build_engines openssl.pc/g' $USING_OPENSSL/Makefile
sed -i -e 's/DIRS= crypto ssl engines.*/DIRS= crypto ssl engines/g' $USING_OPENSSL/Makefile
对于 cURL v7.48.0,我不得不在./configure
之前运行autoreconf
,因为在识别 configuration.ac 的-ldl
时遇到了一些问题。
cd $APP_CURL_DIR && autoreconf && LIBS="-ldl -lpthread" ./configure --prefix=$APP_CURL_DIR/curl --target=$COMPILE_TOOLCHAIN --host=$HOST CC
=mips-unknown-linux-uclibc-gcc --with-ssl=$USING_OPENSSL/OPSSL --enable-static
构建脚本是从 Makefile 复制的,因此如果您的环境中有任何部分不可用,只需修改它以适合您的目标。
最后,在编译 cURL 时,如果您遇到 OpenSSL 标头存在但无法像下面的示例代码那样编译的问题。 也许您不需要修改configure.ac
,请先尝试autoconf
或autoreconf
,然后像我上面发布的那样使用-ldl
选项运行 ./configure 。
