(Reported by Sander and Philipp) When building libmboard on Cygwin using flags --disable-parallel --disable-tests, the following error occured on "make": $ make Making all in src/utils make[1]: Entering directory `/cygdrive/d/Docs/EURACE/X-models/SVN/tags/libmboard-tag/libmboard-0.1.4-alpha/src/utils' .deps/lib_utils_d_la-memlog.Plo:1: *** multiple target patterns. Stop. make[1]: Leaving directory
Submitted By: Shawn Chin Adddate: 2008-12-11 11:29:30 This seems top be a problem with windows paths (c:\\...) finding its way into the Plo file. In .deps/lib_utils_d_la-memlog.Plo: --------------------------------------------------------- lib_utils_d_la-objmap.lo lib_utils_d_la-objmap.o: objmap.c \ ../../include/khash.h \ c:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/stdint.h \ c:/MinGW/bin/../lib/gcc/mingw32/3.4.5/include/stddef.h \ c:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/stdlib.h \ c:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/_mingw.h \ c:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/string.h \ ../../include/mb_objmap.h ../../include/mb_config.h \ c:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/limits.h \ c:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/assert.h ---------------------------------------------------------- See: https://software.sandia.gov/trac/acro/ticket/2835 But why does this only happen on some machines (e.g. Sander/Philipp) and not on others? Has it got to do with MinGW?
Submitted By: Shawn Chin Adddate: 2008-12-11 13:37:12 There are a few similar cases reported on the Internet, most of them blaming the latest release of "make" (who allegedly removed support for Windows paths). Apparently, reverting to an older version of make and libtool solves the problem. Investigating further to see if we can fix this without having users stuck forever with older versions of build tools.
Submitted By: Shawn Chin Adddate: 2008-12-11 13:46:48 Some projects, including Mono, have resorted to having users downgrade "make" on Cygwin stating that the recent version is "broken". See: http://www.mono-project.com/Compiling_Mono_on_Windows
Submitted By: Shawn Chin Adddate: 2008-12-12 13:46:50 It has been confirmed that the problem arrises when Cygwin detects the standalone MinGW's version of gcc (from c:\\MinGW\bin\gcc) as the default gcc. This causes header locations to be specified using WIndows paths, and this doesn't play well with recent versions of "make" within Cygwin. It is not a problem specific to libmboard, and will also affect compilation of other source that uses autotools/libtool. Resolution: * For Philipp, the installation of gcc modules within Cygwin solved the problem. (Note: configure+make must be restarted from a fresh copy of the source as some configuration data from previous "configure" will remain) * For Sander, gcc was already installed in Cygwin but somehow Cygwin is still using the MinGW version as default (has it got to do with the fact that Cygwin was installed after MinGW and the installation picked up on the MinGW compilers?). By reinstalling gcc (v3.3.3-3), the problem was solved. Recommendations to provide if similar reports arrise: a) install gcc in Cygwin and try again using a fresh copy of the source OR b) if MinGW is required, install MSYS and perform compilation within MSYS. OR c) Downgrade the version of "make" in Cygwin. (This ticket is now closed as it is not a problem with libmboard.)
