RTEMS Source Builder Fails on Windows Builds

[Worth Burruss]

The source Builder Fails to build 4.11 tools under MSYS2 and windows. Newer versions of MSYS use a version of gcc greater than 6.0 which can no longer be used to build older version of gcc.

The attached patch is from the gcc mailing list and originally was for gcc version 5.3. It has been adjusted so that it applies to 4.9.3.

This problem should also apply to linux and other systems that use newer gcc 6.0 and above.

[Chris Johns <chrisj@…>]

In e85c673/rtems-source-builder:

MSYS2: Patch to support newer packages.

The patch is contributed by Worth Burruss.

Closes #2990.

[Chris Johns]

Building 4.11.2-rc4 on Windows with a new MSYS2 install has an error on rtems-arm:

In file included from ../../gcc-4.9.3/gcc/cp/except.c:1013:0:
cfns.gperf: In function 'const char* libc_name_p(const char*, unsigned int)':

cfns.gperf:26:14: warning: inline function 'const char* libc_name_p(const char*, unsigned int)' used but never defined
make[2]: *** [Makefile:1059: cp/except.o] Error 1

I am not sure the patch is ok so I am reopening this ticket.

[Chris Johns]

The problem with ARM is the bset file includes an arch specific cfg file. This patch needs to be added to that file.

I suggest you create a new cfg file with just this patch, remove it from config/tools/rtems-gcc-4.9-newlib-2.2.0-1.cfg, then include the file. Also add the include to config/tools/rtems-arm-gcc-4.9.3-newlib-2.2.0-20150423-1.cfg.

[Chris Johns]

Fixed with patch 2433c4b/rtems-source-builder.

This bug effects m32c on the 4.12 (master) branch.

[Chris Johns]

Windows (10 64bit) failures:

1. dtc-1.4.1

2, epiphany gdb-7.8.1

3. lm32 gdb-7.12
4. microblaze gdb-7.12
5. nios2 gcc-7.1.0, newlib-2.5.0.20170623
6. powerpc gdb-7.12
7. sparc gdb-7.12

We need all these issues resolved to branch 4.12.

What's the gdb problem? Is it the same on all the targets failing?

What about the nios2? That would seem to be a different issue.

DTC uses fnmatch and this function is not available on Windows in the MinGW environment. The use of this function makes it difficult to get this tool to work on native Windows.

A couple of solutions come to mind:

1. Fix the DTC tool.
2. Commit a DTB to the moxie project for the DTS and remove the dependency.

I will not fixing DTC on Windows. A new ticket can be opened if this is needed.
