/usr/bin/ld: 找不到 -llibhello_kt（搜索没有帮助）

  • 772

实际上编译了一个共享库

# whereis libhellokt.so
libhellokt: /root/simpleExtension/libhellokt.so

# ls -l /root/simpleExtension/libhellokt.so
-rwxr-xr-x 1 root root 427992 Jun 27 13:02 /root/simpleExtension/libhellokt.so

context - 我想将它包含在 PHP 扩展中。编译行自动生成

装配在舞台上脱落

# cc -shared  -fPIC -DPIC  .libs/hello.o -L/root/simpleExtension -llibhellokt  -O2 -Wl,-rpath -Wl,/root/simpleExtension   -Wl,-soname -Wl,hello.so -o .libs/hello.so
/usr/bin/ld: cannot find -llibhello_kt
collect2: error: ld returned 1 exit status

那些。存在的键

-L/root/simpleExtension -llibhellokt

变量

# echo $LD_LIBRARY_PATH
:./:/root/simpleExtension
# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:.:/root/simpleExtension

他为什么不找她？关节在哪里？

UPD 我用系统库创建了一个指向文件夹的符号链接 - 它没有帮助（我运行了 ldconfig）

# ls -l /usr/lib64/libhellokt.so
lrwxrwxrwx 1 root root 35 Jun 27 14:07 /usr/lib64/libhellokt.so -> /root/simpleExtension/libhellokt.so

    用钥匙启动--verbose，落在

    /usr/libexec/gcc/x86_64-redhat-linux/4.8.5/collect2 --build-id --no-add-needed --eh-frame-hdr --hash-style=gnu -m elf_x86_64 -shared -o .libs/hello.so /usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/crti.o /usr/lib/gcc/x86_64-redhat-linux/4.8.5/crtbeginS.o -L/root/simpleExtension -L/usr/lib/gcc/x86_64-redhat-linux/4.8.5 -L/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64 -L/lib/../lib64 -L/usr/lib/../lib64 -L. -L/root/simpleExtension -L/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../.. .libs/hello.o -llibhellokt -rpath /root/simpleExtension -soname hello.so -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/lib/gcc/x86_64-redhat-linux/4.8.5/crtendS.o /usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/crtn.o --verbose

    使用 key 启动--verbose，看到以下内容：

    attempt to open /root/simpleExtension/liblibhellokt.so failed
attempt to open /root/simpleExtension/liblibhellokt.a failed
attempt to open /usr/lib/gcc/x86_64-redhat-linux/4.8.5/liblibhellokt.so failed
...

    那些。如果库编译为libSomeName.so, 则指定为SomeName, WITHOUT prefix lib(and WITHOUT suffix .so)

  2. 尝试-llibhellokt不-lhellokt
