Parallel make help needed

Parallel make help needed

[Jan D.]

Hello.

Whenever I make bootstrap -jX where X > 1 I get this error:

../../../current/build-aux/install-sh -c -d 
../../../current/doc/lispref/../../info
../../../current/build-aux/install-sh -c -d 
../../../current/doc/lispintro/../../info
../current/build-aux/install-sh -c -d ../current/info
../../../current/build-aux/install-sh -c -d 
../../../current/doc/emacs/../../info
../../../current/build-aux/install-sh -c -d 
../../../current/doc/misc/../../info
makeinfo --force -I../../../current/doc/misc/../emacs --no-split -o 
../../../current/doc/misc/../../info/ccmode.info 
../../../current/doc/misc/cc-mode.texi
../../../current/doc/misc/../../info/ccmode.info: No such file or directory
make[3]: *** [../../../current/doc/misc/../../info/ccmode.info] Error 1
make[3]: *** Waiting for unfinished jobs....
mkdir: ../../../current/doc/lispintro/../../info: File exists
mkdir: ../current/info: File exists

It looks like there is a race in creation of current/info.
How does one go about debugging this?

may help, but you may want to investigate why you apparently don't have
a working 'mkdir -p' on your system, and also check your
build-aux/install-sh version (see doc of AC_PROG_MKDIR_P).

Thats easy, it is not a GNU mkdir.

And now it works without errors.  I'll see if it comes back.

Thanks,

https://www.gnu.org/software/autoconf/manual/autoconf-2.65/html_node/Limitations-of-Usual-Tools.html

says that non-ancient BSD mkdir's are parallel-safe. Isn't that what OS X uses?
Anyway, that would be something to take up with the autoconf folks.

It was probably the ccmode issue. It sorted of looked as if your
install-sh was not parallel-safe, but that may have been a bogus
conclusion.

Yes, but the configure test only checks for Gnu mkdir.  If not, it is install-sh.

That was probably it.
