Developer Tools
Install the following tools:
- Git 2.7+
- GCC 7.1+ or Clang
- CMake 3.12+
Git
You can install git as follows: sudo pkg install git
CMake
You can install cmake as follows: sudo pkg install cmake
Before version 3.10.0, you will need to modify /usr/local/share/cmake/Modules/FindPkgConfig.cmake
as follows
endif()
endif()
+ if(CMAKE_SYSTEM_NAME STREQUAL "FreeBSD" AND NOT CMAKE_CROSSCOMPILING)
+ list(APPEND _lib_dirs "libdata/pkgconfig")
+ endif()
list(APPEND _lib_dirs "lib/pkgconfig")
list(APPEND _lib_dirs "share/pkgconfig")
gcc
You can install gcc7 as follows sudo pkg install gcc7-devel
You will need to set environment variables as follows (for sh, bash, zsh):
CC=gcc7; export CC
CXX=g++7; export CXX
CPP=c++7; export CPP
CXXFLAGS=-std=gnu++17; export CXXFLAGS
Libraries
Install the following libraries:
- cspice (compile, install by yourself, and rename cspice.a and csupport.a to libcspice.a and libcsupport.a for convenience.)
- libGL (
sudo pkg install libGL
) - GLEW (
sudo pkg install glew
) - Freeimage (
sudo pkg install freeimage
) - libsysinfo (
sudo pkg install libsysinfo
) - libinotify (
sudo pkg install libinotify
) - GDAL (
sudo pkg install gdal
)
Some other libraries will be needed….
Compilation
remove minizip line in assimp/CMakeLists.txt.
To avoid linking issues of minizip, remove next line
use_pkgconfig(UNZIP minizip)
in ext/ghoul/ext/assimp/CMakeLists.txt.
Background
use_pkgconfig
macro defined in cmake-modules/FindPkgMacros.cmake
doesn’t work for FreeBSD at now. FindPkgMacros.cmake
depends on FindPkgConfig.cmake
that is contained in cmake distribution, and it doesn’t work for FreeBSD because FreeBSD’s pkgconfig dir is ${PREFIX}/libdata/pkgconfig
that is different with usual one. This directory structure is not considered by FindPkgCOnfig.cmake. Thiis issue will be fixed if merge-request is accepted: Merge request !1108 on gitlab at kitware
