问题
I'm trying to use Eclipse to edit sources, compiled under C++ Builder, but stuck with Unresolved inclusion problem.
For example, code like:
#include <vector>
Gives Unresolved inclusion: <vector> error in Eclipse IDE. C++ Builder indeed has no vector file, instead it has vector.h which is used by compiler.
Eclipse IDE gives no error if I write
#include <vector.h>
How do I tell Eclipse to use vector.h when it sees #include <vector>?
回答1:
This allowed me to avoid Eclipse "Unresolved inclusion" error.
In my case I had to find the location of the C++ vector header on my computer (which is a Mac):
find /usr/local -name vector -print
I found the correct include location in folder "/usr/include/c++/4.2.1". Then I set my project eclipse settings like so:
Project->Properties->C/C++ General->Paths and Symbols->GNU C++->(Add)->"/usr/include/c++/4.2.1"
I'm not using C++ Builder, but my solution might address part of your trouble.
回答2:
You could also try use "CDT GCC Built-in Compiler Settings". Go to the project properties > C/C++ General > Preprocessor Include Path > Providers tab then check "CDT GCC Built-in Compiler Settings" if it is not.
None of the other solutions (play with include path, etc) worked for me for the type 'string', but this one fixed it.
回答3:
memory and memory.h don't refer to the same source.
One is for c, the other for c++
Do you have the right includes source in your project settings ?
回答4:
On Windows, with Eclipse CDT Oxygen, none of the solutions described here worked for me (including the "Provider" - "CDT GCC Built-in Compiler Settings"). What works for me is:
- Install Cygwin, with notably the following packages (maybe not all are strictly needed for this):
- libgcc1
- cygwin32-gcc-core, cygwin32-gcc-g++
- gcc-g++
- mingw64-x86_64-gcc-core, mingw64-x86_64-gcc-g++
- In Project Properties:
- Go to "C/C++ Build" - "Tool Chain Editor" and select "Cygwin GCC" as the "Current toolchain":
- Go to "C/C++ General" - "Preprocessor Include Paths, Macors etc.", in the "Providers" tab, select:
- "CDT Users Setting Entries" (I need them for other includes, such as the Google Test ones, which I manually referenced);
- "CDT GCC Built-in Compiler Settings Cygwin".
