LLVM Clang 3.8.0 on CodeBlocks - Strange errors

[stahta01]

I did see the problem on Windows 7 SP1 (32 bit) using 3.7.?

Edit: I am thinking the CLang 3.7 downloads do NOT include all the compiler files.
Because 3.8 is twice as big.

Please give more information on your Windows OS and Compiler.

OS: Windows 10 64bit
Compiler: Clang download from here http://llvm.org/releases/download.html LLVM 3.7.1 > Clang for Windows (64-bit) (.sig)

Do you know how to install and uninstall software on a Windows computer?
Because, I am starting to believe you have no idea on the correct way to install software.
What options are you picking during the installation of the software?
Did you uninstall the old software using the Windows Control panel?

I've been a Windows user since forever
My answer to all those question is: of course

What options are you picking during the installation of the software?

I just set the destination folder to be Program Files(x86) > CodeBlocks and defined the PATH variable for Clang.

I don't know what other information you need...

Then, I suggest you need retraining!!!!!!
You should never put 64 bit files under "Program Files(x86)"!!
I normally also; do NOT use spaces in the path for compilers that are NOT native to Windows!
And you should NOT be installing the files inside another programs installation folder!

Okay, I reinstalled Clang putting the folder into C:\ directly

do NOT use spaces in the path for compilers that are NOT native to Windows!

Okay, there are no spaces in C:\ directory
Even though the Clang installer automatically set its destination folder to Program Files which has spaces

And you should NOT be installing the files inside another programs installation folder!

Aaalright

Done everything. Result? Nothing.

Looks like at least the 32 bit version of LLVM does NOT include the compiler headers like "iostream".

Going to get the laptop out of my car; likely the 64 bit versions also do NOT include the headers; but, somehow it worked earlier in the day on the laptop. I am guessing you will need to do research on where the headers are supposed to be downloaded from.

NOTE: LLVM and CLang are two separate things; you might need to download CLang++ along with the headers.

If you have news, I'd be glad to hear

Otherwise I guess I will let bygones be bygones with Clang on Windows

From trying option of "-v" suggested here http://clang.llvm.org/docs/LibTooling.html#libtooling-builtin-includes

I found the the Windows system variable of "INCLUDE" changes the clang operation.

Likely my laptop has a "good"  "INCLUDE" value; and my desktop does NOT.
Note: I have no idea where the headers are supposed to be found.

I suggest once more finding a CLang support site.

Clang is a *compiler* and <iostreams> is a header of the STL *library*. The 2 are separate things although very often shipped together. Clang's implementation is here:  http://libcxx.llvm.org/   and doesn't seem to include a Windows port. You'll have to download and install another implementation of the STL library, like the gnu one (libstdc++)

Thank you for that info on Clang.
