'NOEXCEPT' does not name a type

[antonlukyanov]

When I compile curlcpp on Windows with MinGW I get the following error:

$ make
Scanning dependencies of target curlcpp

make[2]: *** [src/CMakeFiles/curlcpp.dir/curl_header.cpp.obj] Error 1

How can I fix this?

Hi @antonlukyanov ,
can you try replacing it with noexcept?

[antonlukyanov]

@JosephP91, replacing NOEXCEPT to noexcept solved the problem, thanks. However, there are many places in headers where NOEXCEPT is used and everything compiles fine except for curl_header.h.

[JosephP91]

@antonlukyanov yes, I noticed this thing now. It's very strange. @qqiangwu how is this possible? In curl_header.h and curl_header.cpp, if I replace NOEXCEPT with noexcept, everything compiles. If I use NOEXCEPT it does not compile.

[qqiangwu]

@antonlukyanov What's your compiler? gcc or mingw?

[JosephP91]

@qqiangwu I think MinGW. It is written in the first comment.

[antonlukyanov]

@qqiangwu, here is more precise information about used compiler:

$ g++ --version
g++.exe (i686-posix-dwarf-rev0, Built by MinGW-W64 project) 4.9.1

[qqiangwu]

@JosephP91 I forgot to add #include "curl_config.h" to curl_header.h, so the macro NOEXCEPT cannot be found and be parsed as a normal symbol.

[JosephP91]

@qqiangwu Oh, ok! I added the include. Thank you!

[JosephP91]

Solved

[qqiangwu]

@JosephP91 BTW, destructors are by default noexcept, so the NOEXCEPT in ~curl_header() NOEXCEPT; is redundant. :)

[JosephP91]

@qqiangwu So I could remove the NOEXCEPT from every destructor declaration. Right?

[qqiangwu]

@JosephP91 Yeah! See also http://en.cppreference.com/w/cpp/language/noexcept_spec

[JosephP91]

It's always good to learn something! Thank you!

I still see this error when I compile with curl...
c:/.../curlcpp/include/curl_exception.h:64:25: error: expected ';' at end of member declaration
~curl_exception() NOEXCEPT;
^
In file included from c:/.../curlcpp/include/curl_easy.h:33:0,

c:/.../curlcpp/include/curl_config.h:32:22: error: 'noexcept' does not name a type
#define NOEXCEPT noexcept
etc.
I'm using the recent package of curlcpp and my gcc compiler version is even newer:
$ gcc --version
gcc.exe (i686-posix-dwarf-rev1, Built by MinGW-W64 project) 4.9.2

Any suggestions how to fix this compilation error? I don't want (and don't think I should be) to remove NOEXCEPT from curlcpp package as it compiles just fine and I was able to create the library.
