Question

我正在使用WSO2 CPP开发在ARM处理器上运行的应用程序。当我在编译时遇到错误时，我正试图在基于Linux的PC计算机中交叉编译库。我已将WSO2配置为：


    export CXXFLAGS="-O2 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -ftree-vectorize -ffast-math -mfloat-abi=softfp"
    export CXXFLAGS=${CXXFLAGS}" -I/home/logic/Logic_BSPs/Linux_3.0/1021559_LogicPD_Linux_BSP_2.0-5p1/rootfs/usr/include"
    export LDFLAGS=" -L/home/logic/Logic_BSPs/Linux_3.0/1021559_LogicPD_Linux_BSP_2.0-5p1/rootfs/usr/lib"

    INSTALL_DIR=/home/logic/Logic_BSPs/Linux_3.0/1021559_LogicPD_Linux_BSP_2.0-5p1/rootfs/usr

    CC=/opt/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc \
    CXX=/opt/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-g++ \
    AR=/opt/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-ar \
    RANLIB=/opt/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-ranlib \
    ./configure --prefix=${INSTALL_DIR} \
        --build=i686-linux --host=arm-none-linux-gnueabi \
        --target=arm-none-linux-gnueabi --with-apache2=no

编译时，报告的错误是：

    /opt/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc -DHAVE_CONFIG_H -I. -I../../../../.. -I../../../../../include -I../../../../../src/core/transport -I../../../../../src/core/transport/http -I../../../../../src/core/transport/http/sender/libcurl -I../../../../../src/core/description -I../../../../../src/core/context -I../../../../../src/core/phaseresolver -I../../../../../src/core/engine -I../../../../../src/core/deployment -I../../../../../util/include -I../../../../../axiom/include -g -O2 -D_LARGEFILE64_SOURCE -ansi -Wall -Wno-implicit-function-declaration -g -D_GNU_SOURCE -DAXIS2_SVR_MULTI_THREADED -DAXIS2_SSL_ENABLED -MT ssl_stream.lo -MD -MP -MF .deps/ssl_stream.Tpo -c ssl/ssl_stream.c  -fPIC -DPIC -o .libs/ssl_stream.o

    ssl/ssl_utils.h:49: error: expected declaration specifiers or '...' before 'SSL_CTX'
    ssl/ssl_utils.h:50: error: expected declaration specifiers or '...' before 'SSL'

看起来有错误的库尚未配置CXXFLAGS变量：如您所见，编译命令中不包括/ home / logic / logic。

你能解决这个问题吗？

谢谢和最诚挚的问候， Joaquim Duran

Answer 1

问题是它无法找到openssl的包含文件。

    ssl/ssl_stream.h:26:25: error: openssl/ssl.h: No such file or directory

首先检查为正在编译的环境安装openssl的位置，然后您需要通过使用'-I'编译标志指定包含路径来告诉编译器这些包含的位置。

配置包含路径时，请尝试使用绝对路径，而不是使用多个“../”路径的长相对路径。它更容易调试包括路径问题。

我遇到了同样的问题。对我来说这是两件事。我需要指定CFLAGS，而不仅仅是CXXFLAGS。另外，我在我的路径中使用〜指向home，由于某种原因构建过程不喜欢它。
