- John Colvin (3/11) Nov 04 2016 Bug, fixed in master(s). Use --compiler=ldmd2 instead.

So I'm working on the checkedint pull request (really need to get that in...) and was trying to get some benchmarks going with ldc. The stock ldc on mint is outdated and it can't compile the code, so I needed to do a self-installation. I've put it in ~/bin/ldc2-1.1.0-beta3-linux-x86. Then: $ PATH=~/bin/ldc2-1.1.0-beta3-linux-x86/bin:$PATH $ dub test --compiler=ldc2 I get: Performing "unittest" build using ldc2 for x86. checkedint_andralex 0.0.8: building configuration "__test__library__"... /usr/bin/ld: cannot find crt1.o: No such file or directory /usr/bin/ld: cannot find crti.o: No such file or directory /usr/bin/ld: cannot find -lrt /usr/bin/ld: cannot find -ldl /usr/bin/ld: cannot find -lpthread /usr/bin/ld: cannot find -lm /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/5/libgcc.a when searching for -lgcc /usr/bin/ld: cannot find -lgcc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/5/libgcc_s.so when searching for -lgcc_s /usr/bin/ld: cannot find -lgcc_s /usr/bin/ld: cannot find -lc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/5/libgcc.a when searching for -lgcc /usr/bin/ld: cannot find -lgcc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/5/libgcc_s.so when searching for -lgcc_s /usr/bin/ld: cannot find -lgcc_s /usr/bin/ld: cannot find crtn.o: No such file or directory collect2: error: ld returned 1 exit status Error: /usr/bin/gcc failed with status: 1 ldc2 failed with exit code 1.

About the compilation problems that you're observing, it's most likely due to LDC issue https://github.com/ldc-developers/ldc/issues/1819, which has been fixed since LDC 1.1.0-beta3, though no new version of LDC have been released since the bug was fixed. You can either build LDC master from source, or workaround the problem by presenting LDC as DMD via ldmd2, that is: dub run checkedint:tests --build=release --verbose --compiler=$HOME/bin/ldc2-1.1.0-beta3-linux-x86_64/bin/ldmd2So I'm working on the checkedint pull request (really need to get that in...) and was trying to get some benchmarks going with ldc.

If this is intended it will probably work fine but you'll have to install the 32bit libc and gcc libraries.
