尝试链接我的项目时遇到了麻烦:

arm-linux-gnueabihf/bin/ld: ~/libcrypto_t.a(mem_dbg.o): relocation R_ARM_THM_MOVW_ABS_NC against 'a local symbol' an not be used when making a shared object; recompile with -fPIC
libcrypto_t.a: could not read symbols: Bad value

所以我想我没有将 openssl 构建为共享对象。我厌倦了这样做

export cross=arm-linux-gnueabihf-
    cd openssl-1.0.1e
    ./Configure dist --prefix=$HOME/opensslArm
    make CC="${cross}gcc" AR="${cross}ar r" RANLIB="${cross}ranlib" CFLAGS="-fPIC" CXXFLAGS="-fPIC"

但是我马上遇到了一个错误(如果我省略了 CFLAGS 和 CXXFLAGS 它编译得很好):

making all in crypto...
make[1]: Entering directory `/home/dev/openssl-1.0.1e/crypto'
( echo "#ifndef MK1MF_BUILD"; \
    echo '  /* auto-generated by crypto/Makefile for crypto/cversion.c */'; \

您可以使用此命令将 -fPIC CFLAG 添加到 Makefile

./Configure dist -fPIC

然后打电话

make CC="${cross}gcc" AR="${cross}ar r" RANLIB="${cross}ranlib"

使用编译器选项 -fPIC 进行编译
