Question

我检查了所有以前的主题，设置

LD_LIBRARY_PATH并相应地遵循。但仍然没有问题。

我正在尝试执行cherrypicker软件并以这种方式执行：

./cherrypicker.sh input.txt

错误讯息：

我查了usr/lib但是没有这样的文件。

在目录中：cherrypicker1.01/tools/crf++/.libs我找到了以下文件

crf_learn        feature_index.o  libcrfpp.lai       lt-crf_test  tagger.o
crf_test         feature.o        libcrfpp.o         node.o
encoder.o        lbfgs.o          libcrfpp.so.0.0.0  param.o
feature_cache.o  libcrfpp.a       lt-crf_learn       path.o

对此有何建议？

Answer 1

请按照以下步骤操作

转到http://taku910.github.io/crfpp/#download并下载CRF ++ - 0.58.tar.gz
解压文件并执行./configure，make install
在父目录中查找文件sudo find ./ | grep libcrfpp.so.0，从那里您将获得丢失文件所在的位置
将该文件复制到/usr/lib和cherrypicker1.01/tools/crf++/.libs/

现在它应该工作

Answer 2

库所在的路径取决于传递给--prefix到configure脚本的值。如果未传递，则根据源代码，默认路径为/usr/local/。

实际上，默认情况下/usr/local/lib不存在系统搜索动态库的路径。因此，人们可以这样做：

echo "/usr/local/lib/" | sudo tee /etc/ld.so.conf.d/CRF.conf
sudo rm -f /etc/ld.so.cache
sudo ldconfig

现在，执行：

ldd $(which crf_test)

输出应类似于：

linux-vdso.so.1 (0x00007ffefc1f0000)
libcrfpp.so.0 => /usr/local/lib/libcrfpp.so.0 (0x00007f6b715b4000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f6b71398000)
libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007f6b71016000)
libm.so.6 => /lib64/libm.so.6 (0x00007f6b70d0e000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f6b70af7000)
libc.so.6 => /lib64/libc.so.6 (0x00007f6b70737000)
/lib64/ld-linux-x86-64.so.2 (0x00007f6b717f3000)

CRF开发人员可能希望使用RPATH将/usr/local/lib/或$PREFIX/lib硬编码为二进制文件中要搜索的目录之一。要检查二进制文件是否包含RPATH，请执行以下操作：

objdump -x $binary | grep RPATH

加载共享库时出错：libcrfpp.so.0
