Hello.
The attached patch fixes bug#29188.
The problem was with "--build-dir=": the old texi2dvi (which is a
shell script) splits "--build-dir=xxx" into "--build-dir" and "xxx",
interprets the "--build-dir" switch as "--batch" (checks just the
first letter, great) and the "xxx" stays on the command line and is
being treated as another input file, causing the error.
Fortunately, since texinfo-4.9, one can set the build directory with
an environment variable "TEXI2DVI_BUILD_DIRECTORY". Unfortunately,
texinfo has a bug there, too. When setting "--build-dir=" on the
command line, the build mode is set to "tidy" (which cleans some log
files, etc.). Fine. The problem is that if you set the build directory
using an environment variable, the mode is NOT set to "tidy", leaving
the logs files and failing tests. Luckily, you can also set the build
mode from an environment variable, "TEXI2DVI_BUILD_MODE".
That's why the new invocation of $(TEXI2DVI) and $(TEXI2PDF) has 2
additional environment variables prepended.
Testing:
- verified - the failing test doesn't work with old texinfo
- verified - the failing test works after the fix with old texinfo
- verified - the failing test works after the fix with new texinfo
- verified - all 84 texi+txi+info tests work after the fix with new
texinfo (make check TESTS="`ls t/*texi*.sh t/*txi*.sh t/*info*.sh`")
- verified - all 84 texi+txi+info tests work after the fix with old
texinfo
Yes, I downloaded texinfo 4.8 just for this purpose.
So, the old texinfo, which doesn't support "--build-dir=" or the
environment variables, should work without change, and the new texinfo
got switched from command-line switches to environment variables and
should work as well, the same way it used to be.
