2.8.1 [makeotf] ValueError: path is on drive c:, start on drive F:

[LIXiangChen]

My Python was installed on C, and font project files are in a path on F. Execute makeotf -f "font.ps" -fi "fontinfo" -ff "../table" -ch "../../_CMap/CJK-UTF32-H" -cs 25 -cl 33 -omitMacNames -r -nS is all good in 2.7.2, but in 2.8.1 will return:

makeotf [Warning] Could not find an Adobe CMAP Mac encoding mapping file. If you want a Mac cmap subtable, please specify the Mac CMAP encoding file with the '-cm' option.
makeotf [Warning] Could not find a Unicode Variation Sequence file in the expected 'c:\python27\lib\site-packages\afdko\resources' subdirectory.

mergeFonts is also broken. Call mergeFonts -cid "fontinfo" "font.ps" "../../_map/new/m_NOTDEF.map" "g_Latin.pfa" and return:

mergeFonts: --- ../../_map/new/m_NOTDEF.map
mergeFonts: bad font file: ../../_map/new/m_NOTDEF.map
mergeFonts: fatal error

[readroberts]

I see two different issues in your reports. Your first comment shows a bug in makeotf, in that it should deal more gracefully with not being able to make a relative path between the temp file and the target path. I think makeotf should not attempt to do this when the files are on different drives.

The second issue shows that mergeFonts does not recognize 'm_NOTDEF.map' as a mapping file. mergeFonts works on my system, so I suspect that the expected text is not present in the mapping file, that would cause it to be recognized as such. Did you follow the rules described in the output from 'mergefonts -h'?

@LIXiangChen I'm working on a fix to the makeotf problem. As for the mergefonts problem, you need to change mergeFonts to mergefonts in the mapping files, otherwise the tool will attempt to parse those files as if they were fonts.

[miguelsousa]

All the tools' names were changed to all-lowercase in #511 (v2.8.0)

[LIXiangChen]

@miguelsousa Yes, that's exactly mergefonts keyword case caused it. Thx.
