This seems quite undesirable.
Do you have any idea if this is going to be fixed?
I look forward to your update.
Cheers,
Santiago

Meanwhile I found gcc from the gcc package looks for headers in /usr/include, 
but gcc from mingw does not (!)

I found a few misc issues, and I will update hopefully soon.

Re: [OMPI devel] Open MPI vs msys2

2018-10-23 Thread Santiago Serebrinsky 
Gilles,

You are right, I have

$ pacman -Ql msys2-runtime-devel | grep stat
msys2-runtime-devel /usr/include/cygwin/stat.h
msys2-runtime-devel /usr/include/sys/stat.h
msys2-runtime-devel /usr/include/sys/statfs.h
msys2-runtime-devel /usr/include/sys/statvfs.h

So I wouldn't know why the error message.
The following lines from config.log (previously attached) seem puzzling to
me:

configure:65237: checking for sys/stat.h
configure:65237: result: yes
configure:65237: checking sys/statfs.h usability
configure:65237: gcc -c -O3 -DNDEBUG -finline-functions
-fno-strict-aliasing  conftest.c >&5
conftest.c:423:10: fatal error: sys/statfs.h: No such file or directory
 #include 
  ^~
compilation terminated.

On one hand, it seems that /usr/include is in the search path for headers
(stat.h is found).
On the other hand, statfs.h is not found, as if /usr/include were not in
the search path for headers.

If I try

export CPATH=/usr/include
export C_INCLUDE_PATH=/usr/include
export CPLUS_INCLUDE_PATH=/usr/include

I get other, much earlier errors.

These observations directly conflict with Dimitry's statement (and the 
link does not state statfs.h and friends


are not available on msys2)

Dear Gilles,

I did what you suggested
  $ pacman -Syu  (a few times, until no further updates)
  $ pacman -S msys2-runtime-devel

but I still get the same error. I am attaching the corresponding log file.
I note that Dmitry mentioned that statf/statvfs are not provided in 
Msys2, so I wonder how you got it with msys2-runtime-devel (which I 
added).

Santiago,


the config.log reports there is no /usr/include/sys/statfs.h on
your system.

on my system, this file exists and is provided by the
msys2-runtime-devel file,

so the first steps are to check this package is installed and if not,
install it.


note I ran pacman -Syu a few times to make sure my system is up to
date.


Cheers,


Gilles
