You should look at the depend.make files in your binary tree. It will be in CMakeFiles/target.dir/depend.make. Try to find one of those that is missing a .h file that you think it should have. Then create a bug report for cmake or email the cmake mailing list.
C99 says (§6.4.7/3): If the characters ‘, \, “, //, or /* occur in the sequence between the < and > delimiters, the behavior is undefined. Similarly, if the characters ‘, \, //, or /* occur in the sequence between the ” delimiters, the behavior is undefined. (footnote: Thus, sequences of characters that resemble escape … Read more
This answer ignores C headers – both the <meow.h> and <cmeow> ones. Of the C++ library headers (all references are to N4659): <initializer_list> is guaranteed to be included by: <utility> (§23.2.1 [utility.syn]) <string> (§24.3.1 [string.syn]) <array> (§26.3.2 [array.syn]) <deque> (§26.3.3 [deque.syn]) <forward_list> (§26.3.4 [forward_list.syn]) <list> (§26.3.5 [list.syn]) <vector> (§26.3.6 [vector.syn]) <map> (§26.4.2 [associative.map.syn]) <set> (§26.4.3 … Read more
Python is a framework on Mac OS X so you need to, #include <Python/Python.h> You also need to call gcc with the -framework argument to actually do anything inside C, gcc -shared -o sample.so sample.c -framework Python
For a list of C standard C headers (stdio, stdlib, assert, …), prepend a c and remove the .h. For example stdio.h becomes cstdio. For other headers, use extern “C” { #include “other_header.h” }
Since this answer still gets voted up, I want to point out that you should almost never need to look in the header files. If you want to write reliable code, you’re much better served by looking in the standard. So, the answer to “where can I find the complete definition of off_t” is “in … Read more
Converting C source code files to an executable program is normally done in two steps: compiling and linking. First, the compiler converts the source code to object files (*.o). Then, the linker takes these object files, together with statically-linked libraries and creates an executable program. In the first step, the compiler takes a compilation unit, … Read more
According to the manual, passing -std=gnu11 enables C99 instead of GNU inline semantics. This means inline, static inline and extern inline all behave differently. In particular, inline expects an external definition in a separate translation unit (which you can provide without duplicating the definition – see this answer).
It’s possible. I wrote a tool years ago to scan a file for C++ enum syntax using pyparsing. It’s now a pyparsing example that I’ve reproduced here in case the link changes. As you can see the file doesn’t have to even be entirely valid C++. It defines the enum grammar and scans the file … Read more
No, it is not safe – it won’t pollute another namespace, but it is dangerous for other reasons: A using directive will import anything that is currently visible by the name you specify into the namespace where you use it. While your using will only be visible to users of MyNamespace, other things from “outside” … Read more
