视觉slam14讲第四章，useSophus未定义的引用
已采纳
make sophus时就有问题,修改了so.cpp
编译例程时候出现：
useSophus.cpp:(.text+0xd2)：对‘Sophus::SO3::SO3(Eigen::Matrix const&)’未定义的引用
useSophus.cpp:(.text+0xf5)：对‘Sophus::SO3::SO3(double, double, double)’未定义的引用
useSophus.cpp:(.text+0x127)：对‘Sophus::SO3::SO3(Eigen::Quaternion const&)’未定义的引用
useSophus.cpp:(.text+0x1f7)：对‘Sophus::SO3::log() const’未定义的引用
等等，还有很多，请问为什么？

- 回答 1 已采纳 I did a spring cleaning in my code by splitting it up in more Go packages, mainly to help reusability (each "building block" in its own package). After fixing the import errors, I discovered that my program suddenly won't build. Running "go build" returns a nosplit stack overflow error. robot main.init: nosplit stack overflow 120 guaranteed after split check in main.init 112 on entry to robot/web.init 104 on entry to robot/controller.init 96 on entry to robot/slam.init 88 on entry to robot/slam/hector.init 80 on entry to hectormapping/map/mapimages.init 72 on entry to hectormapping/map/maprep.init 64 on entry to hectormapping/map/mapproccontainer.init 56 on entry to hectormapping/scanmatcher.init 48 on entry to hectormapping/map/gridmap/occbase.init 40 on entry to hectormapping/map/gridmap/base.init 32 on entry to hectormapping/map/gridmap.init 24 on entry to github.com/skelterjohn/go%2ematrix.init 16 on entry to math.init 8 on entry to math.init┬À1 0 on entry to runtime.panicindex -8 on entry to runtime.morestack00 runtime.main: nosplit stack overflow 120 guaranteed after split check in runtime.main 128 after runtime.main uses -8 120 on entry to main.init 112 on entry to robot/web.init 104 on entry to robot/controller.init 96 on entry to robot/slam.init 88 on entry to robot/slam/hector.init 80 on entry to hectormapping/map/mapimages.init 72 on entry to hectormapping/map/maprep.init 64 on entry to hectormapping/map/mapproccontainer.init 56 on entry to hectormapping/scanmatcher.init 48 on entry to hectormapping/map/gridmap/occbase.init 40 on entry to hectormapping/map/gridmap/base.init 32 on entry to hectormapping/map/gridmap.init 24 on entry to github.com/skelterjohn/go%2ematrix.init 16 on entry to math.init 8 on entry to math.init┬À1 0 on entry to runtime.panicindex -8 on entry to runtime.morestack00 Does anyone know what this is about? I can't find much documentation as to what might be causing it, except that for some cases this is a bug that supposedly is fixed. Some of the code was split into a new folder in the "src" folder, so that the file structure is now: src/robot/main.go (main() lives here) src/robot/(...) (application-specific packages) src/hectormapping/(...) (stand-alone package used in "robot") I am using Go 1.0.3 on Windows 7 (x64).
- 回答 2 已采纳 I used this plugin as a starting point to create a custom meta box that allows users to select a featured video. The meta box is working great, and now I am trying to figure out how to display the video in the post. The following code displays the video: <video controls="controls" preload="auto" width="100%" height="100%"> <source src="<?php // Retrieves the stored value from the database $meta_value = get_post_meta( get_the_ID(), 'meta-image', true ); // Checks and displays the retrieved value if( !empty( $meta_value ) ) { echo $meta_value; } ?>" type="video/mp4" /> </video> That's great. But I want to write a statement that says "if the post has a featured video, display it, if not display the featured thumbnail." Anyone know how to do this? EDIT: I am getting closer. The following code almost works, but for the posts that have featured images (not videos), it displays an empty video player instead of the featured image. How can I modify the below code so that the featured images work? <?php $slam_featured_video = get_post_meta( get_the_ID(), 'meta-image', true ); if (isset($meta_value)) { echo '<video controls="controls" preload="auto" width="100%" height="100%"> <source src="'. $slam_featured_video. '" type="video/mp4" /> </video>'; } elseif (empty($meta_value)) { echo the_post_thumbnail('full'); } ?>
