  1. 我的构建命令

    g ++ -g -m64 -D_FILE_OFFSET_BITS = 64 -fPIC -I./curl-7.60.0/include -I./jsoncpp-src-0.5.0/include/./jsoncpp-src-0.5.0/libs /linux-gcc-4.4.7/libjson_linux-gcc-4.4.7_libmt.so ./ curl-7.60.0 / lib / .libs / libcurl.so.4.5.0 tests.cpp -otests

  2. .so文件存在

    -rwxr-XR-X。 1 pswluna developer 529763 2018-05-30 18:48 ./curl-7.60.0/lib/.libs/libcurl.so.4.5.0

  3. 但是ldd结果是......(请参阅第3行。)

g ++ -g -m64 -D_FILE_OFFSET_BITS = 64 -fPIC -I./curl-7.60.0/include -I./jsoncpp-src-0.5.0/include/./jsoncpp-src-0.5.0/libs /linux-gcc-4.4.7/libjson_linux-gcc-4.4.7_libmt.so ./curl-7.60.0/lib/.libs/libcurl.so.4.5.0 tests.cpp -otests

此命令 链接您想要的库:./curl-7.60.0/lib/.libs/libcurl.so.4.5.0,但安排在运行时使用该库。

这是您想要的命令:

g++ -g -m64 -I./curl-7.60.0/include -I./jsoncpp-src-0.5.0/include/ \
  tests.cpp \
 -L./jsoncpp-src-0.5.0/libs/linux-gcc-4.4.7 -ljson_linux-gcc-4.4.7_libmt \
 -L./curl-7.60.0/lib/.libs -l:libcurl.so.4.5.0 \
 -Wl,-rpath=$(pwd)/jsoncpp-src-0.5.0/libs/linux-gcc-4.4.7 \
 -Wl,-rpath=$(pwd)/curl-7.60.0/lib/.libs \
 -otests

说明:

  1. 您想使用-rpath告诉动态加载程序 它应该在运行时搜索库
  2. -D_FILE_OFFSET_BITS=64 只有在64位操作系统上构建32位二进制文​​件时才有意义,但是你没有这样做
  3. 在构建主可执行文件时,
  4. -fPIC是完全没必要的。
  5. 命令行上的源和库的顺序,您的订单错误
