1304183 - Local build fails because path to mt.exe has spaces

Status: RESOLVED DUPLICATE of bug 1293675

(Firefox Build System :: General, defect)

Description

[Jorg K (CEST = GMT+2)]

Windows 7 64bit
Mozilla Build Tools 2.2.0
VS 2015 Update 3.

C:\mozilla-source\comm-central\obj-i686-pc-mingw32\config\autoconf.mk
receives
MT = c:/Program Files (x86)/Windows Kits/8.1/bin/x64/mt.exe

leading to this error:

60:47.28 msvc_raise_wrappers.cpp
60:47.33 C:/Users/jorgk/AppData/Local/Temp/make872-4.sh: line 4: syntax error near unexpected token `('

60:47.34 mozmake.EXE[4]: *** Deleting file 'screenshot.exe'

This is quite annoying since I cannot do any work ... and I lose one hour on every failed compile attempt.

As a workaround, moved mt.exe elsewhere, so now I get in autoconf.mk
MT = c:/mozilla-build/7zip/mt.exe

Here goes the third hour of compilation.

Maybe a regression form bug 1289246. I haven't compiled on this particular machine since June. I'n July/Aug and Sept. I've been using newly setup Win 10 machines, but today I returned to the Win 7 box just to find that I can't build on it any more.

Further to comment #1: Moving mt.exe to a folder without spaces in the name worked.

Comment 4

[Mike Hommey [:glandium]]

Did you disable 8.3 file names in some directories? See bug 1294475

Comment 5

[Jorg K (CEST = GMT+2)]

Yes, since my development environment is on an SSD, I switched off 8.3 file names as a measure to reduce disk access. This is commonly done in SSD "optimisation tools".

Comment 6

[Mike Hommey [:glandium]]

That's the cause of this bug. The build system doesn't like spaces in various paths, MT being one of them. So for now, the build system relies on getting the short path (8.3) for them. For now, you need to enable 8.3 file names on the MSVC path.
