| Summary | 0000463: build failure on Linux when mono 5 is installed | ||||||||
| Description | Mono 5 installs both csc and mcs binaries. If the mercury configure script is invoked *without* --with-csharp-compiler=/path/to/mcs, then csc is selected as the C# compiler: $ ./configure <snip> checking for mono... /usr/bin/mono checking for a C sharp compiler... checking for csc... /usr/bin/csc checking version of .NET libraries... 4.0.0.0 This leads to an eventual build failure: mmc --generate-dependencies --grade reg.gc --mercury-linkage shared --flags LIB_FLAGS --flags INTER_FLAGS -R/usr/lib64/mercury/lib/reg.gc -R/usr/lib64/mercury/lib --no-warn-nothing-exported --no-warn-unused-imports mer_std mercury_compile: `--host-env-type posix` is incompatible with `--csharp-compiler-type microsoft'. Mercury Compiler, version 14.01.1, configured for x86_64-pc-linux-gnu Copyright (C) 1993-2014 The University of Melbourne Usage: mmc [<options>] <arguments> Use `mmc --help' for more information. gmake[2]: *** [/var/tmp/portage/dev-lang/mercury-14.01.1/temp/mmake.ypfgqB:1500: mer_std.depend] Error 1 This looks to be a different flavour of an older bug (see bug 0000255) where the Chicken Scheme Compiler (csc) would be selected as the C# compiler. However this time, the csc binary does pass the 'grep "^Microsoft"' configure check: $ csc Microsoft (R) Visual C# Compiler version 2.6.0.62309 (d3f6b8e7) Copyright (C) Microsoft Corporation. All rights reserved. warning CS2008: No source files specified. error CS1562: Outputs without source must have the /out option specified The version of mono installed is 5.12: $ mono --version Mono JIT compiler version 5.12.0.226 | ||||||||
| Steps To Reproduce | after installing mono 5: $ ./configure $ make | ||||||||

The basic problem is that Mercury's current detection and recognition of C# compilers predates the inclusion of the Roslyn C# compiler in Mono. In particular, Mercury requires (as mentioned in the error message), that if you are using a MS C# compiler then it needs to be running on Windows. (This is mainly so that it set up the command lines used to invoke the C# compiler appropriately, e.g. use Windows style paths etc.) |
