I’ve been trying to compile newest 1.9.1-p0 ruby on windows 7 x64 but no success. Steps I have followed so far. 1. I have installed Visual Studio 2005 2. I have installed Microsoft Platform SDK 3. I have launched Visual Studio 2005 x64 Win64 command prompt 4. Navigated to the source directory (C:\ruby-1.9.1-p0) 5. In this directory I have executed a) win32\configure --prefix=/usr/local --target=x64-mswin64 b) nmake You can find output from both commands attached. Basically it fails when it tries to build manifest file for miniruby. It fails with the following: cl -nologo main.obj dmydln.obj dmyencoding.obj miniprelude.obj array.obj bignum.obj class.obj compar.obj complex.obj dir.obj enum.obj enumerator.obj error.obj eval.obj load.obj proc.obj file.obj gc.obj hash.obj inits.obj io.obj marshal.obj math.obj numeric.obj object.obj pack.obj parse.obj process.obj random.obj range.obj rational.obj re.obj regcomp.obj regenc.obj regerror.obj regexec.obj regparse.obj regsyntax.obj ruby.obj safe.obj signal.obj sprintf.obj st.obj strftime.obj string.obj struct.obj time.obj transcode.obj util.obj variable.obj version.obj compile.obj debug.obj iseq.obj vm.obj vm\_dump.obj thread.obj cont.obj ascii.obj us\_ascii.obj unicode.obj utf\_8.obj newline.obj acosh.obj cbrt.obj crypt.obj erf.obj lgamma\_r.obj strlcat.obj strlcpy.obj tgamma.obj win32.obj langinfo.obj dmyext.obj oldnames.lib user32.lib advapi32.lib shell32.lib ws2\_32.lib -Feminiruby.exe -link -incremental:no -debug -opt:ref -opt:icf Creating library miniruby.lib and object miniruby.exp miniruby.exe -v ruby 1.9.1p0 (2009-01-30 revision 21907) [x64-mswin64\_80] mt -nologo -manifest miniruby.exe.manifest -outputresource:miniruby.exe;2 NMAKE : fatal error U1077: ‘“C:\Program Files (x86)\Microsoft Visual Studio 8\Common7\Tools\bin\mt.EXE”’ : return code ‘0x1f’ Stop. What am I doing wrong? ---
