找不到链接库(lNrrdIO) [英] Cannot find a link library (lNrrdIO)

问题描述

我正在尝试在Ubuntu 18.04上安装NrrdIO，以运行Marching Cubes来分割医学图像.这是我尝试运行它的链接.

I am trying to install NrrdIO on Ubuntu 18.04, to run Marching Cubes to segment medical images. This is the link from which I'm trying to run it.

我正在尝试安装ijkmcube-v0-3-3.tar，它需要ITKNrrdIO.a库.我遇到了这个错误:

I'm trying to install ijkmcube-v0-3-3.tar, which requires the ITKNrrdIO.a library. I'm running into this error:

[  7%] Linking CXX executable ijkmcube
/usr/bin/ld: cannot find -lNrrdIO
collect2: error: ld returned 1 exit status
CMakeFiles/ijkmcube.dir/build.make:406: recipe for target 'ijkmcube' failed
make[2]: *** [ijkmcube] Error 1
CMakeFiles/Makefile2:131: recipe for target 'CMakeFiles/ijkmcube.dir/all' failed
make[1]: *** [CMakeFiles/ijkmcube.dir/all] Error 2
Makefile:129: recipe for target 'all' failed
make: *** [all] Error 2

我已经安装了NrrdIO 1.11.0，并尝试使用NrrdIO 1.9.0，但是在运行时 制作 我总是会遇到此错误，由于某种原因，它找不到lNrrdIO.有人可以帮忙吗? 谢谢

I've installed NrrdIO 1.11.0, and tried with NrrdIO 1.9.0 as well, but while running make I always run into this error, for some reason its not able to find lNrrdIO . Can someone please help? Thanks

我认为链接存在问题，但是当我将NrrdIO.a文件复制到/usr/bin并修改了符号链接以指向它时，出现如下错误:

I think its a problem with the linking, but when I copied the NrrdIO.a file to /usr/bin and modified the symbolic link to point to it, I got an error as follows:

[  7%] Linking CXX executable ijkmcube
collect2: fatal error: cannot find 'ld'
compilation terminated.
CMakeFiles/ijkmcube.dir/build.make:406: recipe for target 'ijkmcube' 
failed

CMakeFiles/ijkmcube.dir/all' failed
make[1]: *** [CMakeFiles/ijkmcube.dir/all] Error 2
Makefile:129: recipe for target 'all' failed
make: *** [all] Error 2

有人可以帮忙吗?谢谢

已解决

Tsyvarev解决了该问题，必须将libNrrdIO.a文件复制到/usr/lib/.请参阅评论以获取确切的解决方案

Tsyvarev solved it, the libNrrdIO.a file has to be copied to /usr/lib/. Refer to comments for the exact solution

推荐答案

此答案由@Tsyvarev给出:

This answer was given by @Tsyvarev:

通过建立名为ld的链接，您将删除原始链接器(ld).没有链接器，您肯定无法构建任何库.您需要做一个名为lNrrdIO.a的链接，这样它将指向实际的库位置:sudo ln -sfn /home/subham/Downloads/NrrdIO-1.9.0-src/lNrrdIO.a lNrrdIO.a(从/usr/lib目录运行此命令).并恢复原始的/usr/bin/ld文件.

By making a link named ld you are removing the original linker (ld). Without the linker you definitely cannot build any library. What you need is to make a link named lNrrdIO.a, so it will point to the actual library location: sudo ln -sfn /home/subham/Downloads/NrrdIO-1.9.0-src/lNrrdIO.a lNrrdIO.a (run this command from /usr/lib directory). And restore original /usr/bin/ld file.
