[Msys2-users] MSYS2 build of sparc-rtems4.11

[Chris J. <ch...@rt...>]

Hello,

I am working on getting RTEMS tools (http://www.rtems.org/) to build in 
MSYS2 on Windows. We cross-compile for RTEMS and are currently using 
gcc-4.9.2.

I am building a SPARC tools chain and I am seeing a some interesting 
errors when we get to C++'s libsupc++. The issue is not repeatable so I 
have builds that do not fail here and then builds that do. I am using 
'-j 2' on the build.

The first error I have is:

libtool: link: sparc-rtems4.11-ar rc .libs/libsupc++.a 
array_type_info.o atexit_arm.o atexit_thread.o bad_alloc.o

C:\opt\rtems\rsb\rtems-source-builder.git\rtems\build\tmp\sb-chris\4.11\rtems-sparc\C\opt\rtems\4.11\bin\sparc-rtems4.11-ar.exe: 
unable to rename '.libs/libsupc++.a'; reason: Permission denied

and running the command in the directory as shown worked.

The second, again in the same area of gcc is:

libtool: link: sparc-rtems4.11-ranlib .libs/libsupc++.a
libtool: link: sparc-rtems4.11-ranlib .libs/libsupc++convenience.a
C:\opt\rtems\rsb\rtems-source-builder.git\rtems\build\tmp\sb-chris\4.11\rtems-sparc\C\opt\rtems\4.11\bin\sparc-rtems4.11-ranlib.exe: 
.libs/libsupc++convenience.a: File format not recognized

and the .a file is corrupt. The first 8 bytes are 0.

I downloaded a fresh MSYS2 2 days ago.

Any insight would be welcome.
