Boost spirit x3 example calculator (calc8, calc9) linker error

由 若如初见. 提交于 2019-12-08 08:28:23
问题 I'm very new with boost spirit (and with boost). Its very interesting library. I use qtcreator + MinGW 5.3. I simply add every source file from git_hub_calc8 into new project and add some boost library, but i got the following error trying to build (All other examples work fine) C:\Program Files\boost\boost\boost\spirit\home\x3\nonterminal\rule.hpp:113: ошибка: undefined reference to `bool client::parser::parse_rule<__gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char,

Using CImg: LNK1181: cannot open file “m.lib” on windows 7 x64

由 孤街浪徒 提交于 2019-12-08 05:46:04
问题 In the CImg Makefile I notice a flag "-lm" I think this points to the m.lib file. But for some reason it cannot find it during the Linking phase. I am compiling the code using the following command: nvcc -o FilledTriangles FilledTriangles.cu -I.. -O2 -lm -lgdi32 "nvcc" is just the nvidia CUDA compiler. It should function similar to g++ 回答1: -lm refers to "libm.so" In general, -lXYZ is a way of telling the linker that it should resolve the symbols in your compiled code against libXYZ.so (after

Link object files without libSystem macOS

由 牧云@^-^@ 提交于 2019-12-08 04:54:52
问题 I'm writing a compiler for macOS on x86-64, but when I link the object files together, ld says ld: dynamic main executables must link with libSystem.dylib for inferred architecture x86_64 But since libSystem contains libc, I don't want to use it (it would give me lots of duplicates). How can I get around this? 回答1: Use -macosx_version_min 10.6 as ld parameter. This will generate LC_UNIXTHREAD instead of LC_MAIN in your executable. If you want even more control you'd need to get rid of ld in

Linker error - linking two “application” type projects in order to use Google Test

由 北城以北 提交于 2019-12-08 02:31:47
问题 I am trying to test a function with Google Test. It seems that everything is set up correctly, and it builds and executes fine without gtest... (There is a bit of complexity in the code, so I cannot list all the source files here, but without adding gtest, the files are linking properly, and running as they should). It is an application type project. It has a number of library dependencies... irrelevant. The test project is added as a separate project to the solution. It has the tested

How can I resolve single symbol link error when dynamically linking XCode project to lib4cxx library?

由 瘦欲@ 提交于 2019-12-07 13:46:32
I'm writing in C++ under XCode 4.6 on Mountain Lion. I'm trying to add and use the Apache log4cxx library. I installed the library this morning via Brew. I'm linking against liblog4cxx.dylib. I'm getting a link error that just one symbol can't be found: Undefined symbols for architecture x86_64: "log4cxx::Logger::forcedLog(log4cxx::helpers::ObjectPtrT const&, std::__1::basic_string, std::__1::allocator > const&, log4cxx::spi::LocationInfo const&) const", referenced from: I know it's finding the library file because if I remove it, I get lots more undefined symbol errors relating to log4cxx.
