• build LDC with shared libraries (esp. Phobos) Use LDC's ldmd2, a wrapper script for ldc2 which converts argument formats from dmd style over to ldc style.

Requirement: LDC compiled with shared libs, especially Phobos

Example:

https://forum.dlang.org/thread/lbrfycmutwrrghtzazin@forum.dlang.org?page=3

This is a fresh build on Ubuntu 14.04 with cmake called via:

cmake -DCMAKE_INSTALL_PREFIX=/opt/ldc -DBUILD_SHARED_LIBS=ON ..

.

so here we go

https://wiki.dlang.org/Building_LDC_from_source

#+BEGIN_SRC sh

tools

sudo apt install cmake

#https://github.com/ninja-build/ninja/wiki/Pre-built-Ninja-packages sudo apt install ninja-build

llvm (slightly tweaked by the LDC guys)

cd ~/d/glathoud/software mkdir ldc-llvm5-tweak cd ldc-llvm5-tweak

curl -L -O https://github.com/ldc-developers/llvm/releases/download/ldc-v5.0.1/llvm-5.0.1.src.tar.xz tar xf llvm-5.0.1.src.tar.xz cd llvm-5.0.1.src/ mkdir build && cd build/

cmake -GNinja .. -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="X86;AArch64;ARM;PowerPC;NVPTX" -DLLVM_BUILD_TOOLS=OFF -DLLVM_BUILD_UTILS=OFF # remove -GNinja to use Make instead

cd ../../../

now LDC itself

looked there: https://github.com/ldc-developers/ldc/releases

for the latest stable release

mkdir ldc-1.10.0 && cd ldc-1.10.0 curl -L -O https://github.com/ldc-developers/ldc/releases/download/v1.10.0/ldc-1.10.0-src.tar.gz tar xf ldc-1.10.0-src.tar.gz

cd ldc-1.10.0-src/ mkdir /other2/software 2>>/dev/null mkdir build && cd build cmake -G Ninja -DLLVM_CONFIG=../../../ldc-llvm5-tweak/llvm-5.0.1.src/build/bin/llvm-config -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=/other2/software/ldc ..

Build and install LDC. Use -j to limit parallelism if running out of memory.
