I want to install LLVM 13.0.1 in my local windows (64 bit) system to use it for creating a working enviorment for open source project. I downloaded and install from here but I found it is not complete It is missing many library files and cmake files that are required and getting errors while building. so I want now to install LLVM 13.0.1 from source.
I am very early in learning LLVM , Clang so don't have any idea of doing so. Can anyone give me the entire step / commands to do so.

I downloaded Code::blocks to learn C++ on and I chose the Min-GW compiler download choice and installed Code::blocks and added compiler path to the environment variables but when I run g++ --version in the command it gives me the error above.
and I manually Added the compiler path in Code::Blocks app but still gives Couldn't Find the compiler path
I have windows 10 32-bit and this is the version I downloaded
https://sourceforge.net/projects/codeblocks/files/Binaries/20.03/Windows/32bit/codeblocks-20.03mingw-32bit-setup.exe/download
Note: I tried the other download source Foss-HUB but the same thing
I have been trying to get an R package downloaded that requires clang and go fortran to be built. I have neither installed on this computer, and since I am using a common computer I do not have the ability to install Xcode.
I downloaded the clang and fortran packages supplied by R at:
https://cran.r-project.org/bin/macosx/tools/
After installing them I still get the same error: configure: error: C compiler cannot create executables
I am new to creating path modifications and such and wondered if anyone could help?
I saw that his was not answered still, what I ended up doing was installing clang and gofortran through Homebrew, which worked.
Good day all
I have been searching for a method of cross-compiling for QT-Creator in Linux for sometime now, and I have been having alot of trouble with it.
Background info
please note: I am on a Linux machine, and would like to cross compile Windows Apps
My system:
Ubuntu Gnome 16.10
QT Creator 4.0.2 (based on QT 5.7)
I have came across a few SO links, a few blogs with broken instructions, etc and one seeming helpful but dependencies could not be found.
I have also attempted another compiler MXE and cloned and attempted to build the MXE compiler from the GIT repo, which failed (no solution for the build error - VTK build error)
I decided to download precompiled MinGW compilers (i686 and x86_x64 versions) from sourceforge
Issue:
In QT Creator, adding the compiler is done without an issue, adding the "Kit" and selecting the newly added compiler, an red exclamation gives an error
The Compiler (x86_windows_msys_pe_64bit) cannot produce code for QT version 5.7.0 GCC 64Bit (x86_linux_generic_elf_64bit)
This occurs for both 32 + 64 bit compilers.
I think that you should have a QT version that matches your compiler ABI. The error tells you that the MinGW compiler doesn't match the Linux version of QT you have used. Therefore, get a windows version of QT and use it instead (just as you've added WinGW).
You can download Qt Binaries from here.
I need to build KLEE on my Ubuntu 12.04. I followed KLEE website's instructions step by step. I had LLVM 2.9 built. But when I need to install klee-uclibc, and in the process of configuring, it complained that it failed to find a working LLVM bitcode compiler. Does this mean that my LLVM built was unsuccessful? I am new to Linux and new to the testing tool. Any help is greatly appreciated.
I ran into the same problem, but a closer look in klee document helped me fix it. Especially look at step (02)(01):
Install llvm-gcc:
Download and install the LLVM 2.9 release of llvm-gcc from here. On an x86-64 Linux platform you are going to need the archive LLVM-GCC 4.2 Front End Binaries for Linux x86-64.
Add llvm-gcc to your PATH. It is important to do this first so that llvm-gcc is found in subsequent configure steps. llvm-gcc will be used later to compile programs that KLEE can execute. Forgetting to add llvm-gcc to your PATH at this point is by far the most common source of build errors reported by new users.
Hence, make sure that llvm-gcc is installed and a PATH is provided to the executable.
I regularly use Code::Blocks and MinGW for my C/C++ projects. I would like to be able to use OpenCV, since it has a nice library for computer vision projects. They have dropped support for MinGW. I have heard you can build it on your own somehow, but I have no experience doing this with 3rd party libraries. Can someone explain how to build it in a simple way for MinGW?
There is, or at least there was at least until 2.4.6, precompiled version of opencv that works out of the box with mingw as long as you use the dw2(standard) version of mingw.
since i needed sjlj support i had to build my own version of openCV 2.4.6
I did he following - i am pretty sure it will work for the current openCV version as well
Setup your preferred Mingw Environment - i would strongly recommend to use gcc 4.5 or newer
Intstall Msys
Intall Cmake - you can get a binary package
Start the Cmake GUI
Select the openCV source folder
Click Configure and select MSYS-Makfiles
Errors in the first run of Configure might be resolved if you run Configure again
Click Generate
use MSYS make to run the generated makefile
Copy all desired libraries and include files to your mingw-installation or your project
