whitequark 23feb4cf8f TTF: use metrics of 'A' to determine cap height. SolveSpace 2.0 used the height of 'A' (i.e. cap height) to determine the reference height. SolveSpace 2.1 completely broke that during transition to Freetype, and used something more or less random, by using FT_Set_Char_Size with units_per_EM. SolveSpace 2.2 attempted to fix that, but also used something more or less random, by using FT_Request_Size with "unit" values. Turns out that Freetype actually doesn't have a concept of cap height at all. It is possible to extract it from the TT_OS2 table that is present in some TrueType fonts, but it is not present in Microsoft fonts (the msttcorefonts ones), and for those Linux fonts in which it is present it doesn't appear very reliable. So instead, use the height of 'A' instead, like version 2.0 did. This has the advantage that it is quite bulletproof, and also matches exactly what the old files are measured against. One downside is that fonts without an 'A' glyph would not render. We can deal with that when it becomes a problem.		2016-11-02 08:59:33 +00:00

README.md

SolveSpace

This repository contains the source code of SolveSpace, a parametric 2d/3d CAD.

Installation

Mac OS X (>=10.6 64-bit), Windows (>=XP 32-bit)

Binary packages for Mac OS X and Windows are available via GitHub releases.

Other systems

See below.

Building on Linux

Building for Linux

You will need CMake, libpng, zlib, json-c, fontconfig, freetype, gtkmm 2.4, pangomm 1.4, OpenGL and OpenGL GLU. To build tests, you will need cairo. On a Debian derivative (e.g. Ubuntu) these can be installed with:

apt-get install libpng-dev libjson-c-dev libfreetype6-dev \
                libfontconfig1-dev libgtkmm-2.4-dev libpangomm-1.4-dev \
                libcairo2-dev libgl-dev libglu-dev cmake

Before building, check out the necessary submodules:

git submodule update --init extlib/libdxfrw

After that, build SolveSpace as following:

mkdir build
cd build
cmake .. -DENABLE_TESTS=OFF
make
sudo make install

A fully functional port to GTK3 is available, but not recommended for use due to bugs in this toolkit.

Building for Windows

You will need CMake and a Windows cross-compiler. On a Debian derivative (e.g. Ubuntu) these can be installed with:

apt-get install cmake mingw-w64

Before building, check out the necessary submodules:

git submodule update --init

After that, build 32-bit SolveSpace as following:

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-mingw32.cmake \
         -DENABLE_TESTS=OFF
make

Or, build 64-bit SolveSpace as following:

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-mingw64.cmake \
         -DENABLE_TESTS=OFF
make

The application is built as build/src/solvespace.exe.

Space Navigator support will not be available.

Building on Mac OS X

You will need XCode tools, CMake, libpng and Freetype. To build tests, you will need cairo. Assuming you use homebrew, these can be installed with:

brew install cmake libpng freetype cairo

XCode has to be installed via AppStore; it requires a free Apple ID.

Before building, check out the necessary submodules:

git submodule update --init extlib/libdxfrw

After that, build SolveSpace as following:

mkdir build
cd build
cmake .. -DENABLE_TESTS=OFF
make

The app bundle is built in build/src/solvespace.app.

Building on Windows

You will need git, cmake and Visual C++.

Building with Visual Studio IDE

Check out the git submodules. Create a directory build in the source tree and point cmake-gui to the source tree and that directory. Press "Configure" and "Generate", then open build\solvespace.sln with Visual C++ and build it.

Building with Visual Studio in a command prompt

First, ensure that git and cl (the Visual C++ compiler driver) are in your %PATH%; the latter is usually done by invoking vcvarsall.bat from your Visual Studio install. Then, run the following in cmd or PowerShell:

git submodule update --init
mkdir build
cd build
cmake .. -G "NMake Makefiles" -DENABLE_TESTS=OFF
nmake

Building with MinGW

It is also possible to build SolveSpace using MinGW, though Space Navigator support will be disabled.

First, ensure that git and gcc are in your $PATH. Then, run the following in bash:

git submodule update --init
mkdir build
cd build
cmake .. -DENABLE_TESTS=OFF
make
