### Introduction

This is a programmer-friendly portable calculator application, which

runs on Windows, Linux, and Mac. It can evaluate C-like expressions in

256-bit floating-point numbers through

[TLFloat](https://github.com/shibatch/tlfloat) library. It allows

users to choose between decimal and hexadecimal output formats for

integers and floating point numbers. In addition to the math functions

in math.h, various bitwise operations can be performed.

### Building on Linux and Mac

1. Check out the source code from our GitHub repository :

`git clone --recurse-submodules https://github.com/shibatch/octcalc`

2. Make a separate directory to create an out-of-source build :

`cd octcalc && mkdir build && cd build`

3. Run cmake to configure the project :

`cmake .. -DCMAKE_INSTALL_PREFIX=../../install`

4. Run make to build and install the project :

`make && make install`

### Building on Windows

1. Download and install Visual Studio Community 20XX.

  * Choose "Desktop development with C++" option in Workloads pane.

  * Choose "C++ CMake tools for Windows" in Individual components

    pane.

  * Optionally, choose "C++ Clang Compiler for Windows" in Individual

    components pane.

2. Download and install WiX Toolset v3.

  * https://wixtoolset.org/

3. Download and install Windows-MSVC version of Qt6.

  * https://sourceforge.net/projects/fsu0413-qtbuilds/

  * Extract the archive so that c:\opt\qt6\bin\designer.exe is seen.

4. Create a build directory, launch Developer Command Prompt for VS

  20XX and move to the build directory.

5. Set path : `path %PATH%;"c:\opt\qt6\bin"`

6. Check out the source code from our GitHub repository :

`git clone --recurse-submodules https://github.com/shibatch/octcalc`

7. Run the batch file for building with MSVC.

`cd octcalc && winbuild-msvc.bat -DCMAKE_PREFIX_PATH=c:/opt/qt6 -DENABLE_WIX=True`
