gcc-7.1.0

[bdubbs@…]

New major version. Wait for LFS update.

LFS updated...

[Pierre Labastie]

See Changes at ​https://gcc.gnu.org/gcc-7/changes.html A very important part:

Java (GCJ)

The GCC Java frontend and associated libjava runtime library have been removed from GCC.

So I guess the gcc-java page should be archived...

No failure in any test! Yet valgrind and gdb are installed.

[bdubbs@…]

So it would appear that the five failed tests in LFS are due to missing test programs or the limited environment in Chapter 6 when gcc is built.

FAIL: experimental/filesystem/iterators/directory_iterator.cc execution test
FAIL: experimental/filesystem/iterators/recursive_directory_iterator.cc execution test
FAIL: experimental/filesystem/operations/exists.cc execution test
FAIL: experimental/filesystem/operations/is_empty.cc execution test
FAIL: experimental/filesystem/operations/temp_directory_path.cc execution test

All in the libstdc++ section.

I have not investigated the reason for these failures, but they appear to be related.

Replying to bdubbs@…:

All in the libstdc++ section.

I cannot tell for sure those tests are run, since they do not appear in the log if they do not fail. We can compare the number of tests. I have:

                === libstdc++ Summary ===

# of expected passes            11668
# of expected failures          66
# of unsupported tests          296

There are two new languages: "brig" (​http://www.hsafoundation.com/hsa-foundation-announces-results-of-innovative-open-source-project/ and "jit" (​https://gcc.gnu.org/wiki/JIT). I do not understand exactly what they do (specially jit), so I am not sure I want to include them. I'll mention them in the "Command Explanations".

Fixed at r18694

[bdubbs@…]

It looks like LFS runs the same number of tests:

      === libstdc++ Summary ===

# of expected passes    11663
# of unexpected failures   5
# of expected failures     66
# of unsupported tests     296

The only difference is the unexpected failures in LFS.

[Pierre Labastie]

Actually, those tests only fail when run as root (as stated in the book). The reason is that they tests accessibility to files, and root has to much privs.
