问题 I'm adding the stepper indicator library - https://github.com/badoualy/stepper-indicator - to my project. To do so, I added jitpack to my project gradle file and the stepper-indicator library to my app gradle file. However, I'm getting the following build error: Error:Execution failed for task ':app:processDebugManifest'. > Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(25.4.0) from [com.android.support:preference-v14:25.4.0] AndroidManifest.xml:25:13-35 is

Forward declaration & circular dependency

由 痴心易碎 提交于 2020-01-10 14:22:14
问题 I've got two classes, Entity and Level. Both need to access methods of one another. Therefore, using #include, the issue of circular dependencies arises. Therefore to avoid this, I attempted to forward declare Level in Entity.h: class Level { }; However, as Entity needs access to methods in Level, it cannot access such methods, since it does not know they exist. Is there a way to resolve this without re-declaring the majority of Level in Entity? 回答1: A proper forward declaration is simply:

MAVEN POM dependencies and Dependency Exclusions

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Introduction This section discusses the functionality of optional dependencies and dependency exclusions. This will help users to understand what are they, how to use them, how they work and when is the best way to use them. It also explains why exclusions are made as per dependency basis not in a POM level. Optional Dependencies Optional dependencies are used when it's not really possible (for whatever reason) to split a project up into sub-modules. The idea is that some of the dependencies are only used for certain features in the project, and will not be

Creating make rules for dependencies across targets in project's sub-directories

由 一世执手 提交于 2020-01-10 04:42:07
问题 Source code tree ( R ) for my dissertation research software reflects traditional research workflow : "collect data -> prepare data -> analyze data -> collect results -> publish results". I use make to establish and maintain the workflow (most of the project's sub-directories contain Makefile files). However, frequently, I need to execute individual parts of my workflow via particular Makefile targets in project's sub-directories (not via top-level Makefile ). This creates a problem of

How to select the version of the VC 2008 DLLs the application should be linked to?

由 大兔子大兔子 提交于 2020-01-10 02:05:12
问题 I'm using Visual Studio 2008 SP1 for C++. When compiling, Visual Studio needs to choose against which version of the CRT and MFC DLLs the application should be linked, version 9.0.21022.8 (= RTM), 9.0.30729.17 (= SP1) or 9.0.30729.4148 (= SP1 with security update). I'd like to know how you can choose which of both versions will be linked against. Does anyone know? Note : this is important when using a private assembly, because you need to know which versions of the VC 9.0 DLLs to copy along

In what order prerequisites will be made by the GNU make?

由 房东的猫 提交于 2020-01-09 19:40:33
问题 Assuming we have the rule: a: b c d e and b , c , d and e are independent of each other. Is the order of making b , c , d , e defined? It seems that generally they will be made in order b , c , d , e , but may it sometimes happen, that the order will be different? 回答1: Sure, if I use make -j a , they might all get built at the same time (depending on whether b , c , d , or e in turn have other/interrelated dependencies). 回答2: No, the order is not defined. That is the whole point in using

Automatically discovering C dependencies

由 痞子三分冷 提交于 2020-01-09 19:08:11
问题 I'm required to write documentation for my current project that lists all .c files and for each one lists every .h file which is directly or indirectly included by that file. This is a large project, and although we have Makefiles which theoretically have this information, those Makefiles are sometimes incorrect (we inherited this project from another company). We've often had to do a make clean ; make for our changes to actually be reflected in the recompilation, so I don't want to rely on

问题 I am working on a gradle project. I have no issue building and running my project with gradle and seeing the output.
