symbols

问题 Is there a way from WinDbg, without using the DbgEng API, to display the symbol server paths (i.e. PdbSig70 and PdbAge) for all loaded modules? I know that lml does this for the modules whose symbols have loaded. I would like to know these paths for the symbols that did not load so as to diagnose the problem. Anyone know if this is possible without having to utilize the DbgEng API? edited: I also realize that you can use !sym noisy to get error messages about symbols loading. While this does

问题 Consider my small example C library: #include <external_library.h> void some_function(void) { external_library_call(); // Do other stuff... } It plans to make some_function() publicly callable. The library doesn't work, though, because the external library it requires also happens to use a function called some_function(), which happens to have the same prototype. GCC's linker doesn't care how many sources of the some_function symbol there are, though. It picks one seemingly at random and the

问题 I am trying to check whether symbol getaddrinfo_a exists using CMake: list(APPEND CMAKE_REQUIRED_DEFINITIONS -D_GNU_SOURCE) check_symbol_exists(getaddrinfo_a netdb.h HAVE_GETADDRINFO_A) list(REMOVE_ITEM CMAKE_REQUIRED_DEFINITIONS -D_GNU_SOURCE) While getaddrinfo_a is defined in netdb.h (given that _GNU_SOURCE is defined), CMake fails to find it: -- Looking for getaddrinfo_a -- Looking for getaddrinfo_a - not found. Any idea what am I doing wrong? 回答1: According to the getaddrinfo_a man page,

问题 Windows 8. Everything in the settings is set to UTF-8 . Intellij IDEA displays Chinese characters, for example, which means it's really set to Unicode character set, but it displays a box instead of 𝔊 (MATHEMATICAL_FRAKTUR_CAPITAL_G) symbol. Debugger window: 回答1: It's likely that the particular font you're using doesn't contain a glyph for that character. Try switching to another font. 来源： https://stackoverflow.com/questions/39289564/why-intellij-idea-doesnt-display-symbol

问题 In Delphi, you can define symbols, just like in C/C++. Delphi: {$DEFINE MY_SYMBOL} C/C++: #define MY_SYMBOL This allows you to check whether the symbol is defined by using {$IFDEF MY_SYMBOL} in Delphi, or #ifdef MY_SYMBOL in C/C++. This is a boolean value - either the symbol is defined during pre-processing or not. However, C/C++ also allows you to assign values to preprocessor symbols. E.g.: #ifdef DEBUG #define DB_HOST "127.0.0.1" #else #define DB_HOST "123.456.789.123" #endif Database

问题 When I am debugging my app I see messages: cannot find or open the PDB file I seem to remember being able to specify the location of the PDB file while debugging the app. How can I do this?

问题 I have a pom.xml file that has the following structure: <?xml version="1.0" encoding="UTF-8" standalone="no"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>someParentGroupId</groupId> <artifactId>someParentArtifactId</artifactId> <version>someParentVersionId</version> </parent>

问题 This is probably super trivial, but I can't find any information about what the ':>' symbol means in Coq. What is the difference between: U : Type and W :> Type ? 回答1: It depends on where the symbol occurs. If it is inside a record declaration, for instance, it instructs Coq to add the corresponding record projection as a coercion. Concretely, suppose that we have the following definition of a type with an operation: Record foo := Foo { sort :> Type; op : sort -> sort -> sort }. We can now

问题 I am developing an eCommerce application and one of the features is that users can choose their currencies. Now, I noticed that when somebody selects the Russian Ruble, the symbol shows as just a square in Chrome on iOS (version 7.1). Why is that? It should show this: ₽ but it shows this: ▢ Note that I am using the HTML code to display it: ₽ On the desktop version (iMac) it shows fine and I imagine on other operating systems, too. Anybody got a clue why it's not showing in iOS? 回答1: Ruble

问题 In my scenario I want a plugin, which is a shared object loaded in runtime, to access symbols from the “host application” so I can add any functionality to my application. I have tried but have not found any way to do this and I have no clue on whether this is possible or not. So, can I do this somehow or is there any alternative that applications that use plugins use? I am on Fedora 15, Linux 2.6.4. However, I hope the solution will be cross-platform. 回答1: There are three main approaches:
