Question

I m 使用 WSO2 CPP 开发一个在 ARM 处理器上运行的应用程序。当我在编译时发现错误时, 我正试图在基于 Linux 的 PC 计算机中交叉调试库。我将 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

在汇编时,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 
[...]

看起来有错误的库没有配置 CXXFLAGS 变量:您可以看到,在编译命令中不包括 / home/log/logic/logic。

你能解决这个问题吗?

Thanks and Best Regards, Joaquim Duran

Answer 1

问题是它无法找到打开的包含文件。

    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开关的位置, 然后您需要通过指定 - I 编译标记的包含路径来告诉编译器这些内容的位置。

当您配置包含路径时, 请尝试使用绝对路径, 而不是有数条. / 路径的长相对路径。如此调试更容易包含路径问题。

我也有同样的问题。对我来说,这是两件事情。我需要指定CFLAGS,而不仅仅是CXXFLAGS。此外,我在路上用一个~指向家,而建筑过程出于某种原因并不喜欢。
