Report any problems encountered to the
github issue tracker.
(I also maintain a private database at work.)
Below are issues that users have encuontered, with solutions where known.
This page serves as a FAQ for issues that users have encountered.
Many of these issues are not bugs.
Please make sure you fulfill the requirements listed on the
Source page.
Awk
Several linux distros default to mawk as the baseline version
of awk. Unfortunately, mawk is horribly buggy and rejects valid input,
and has been blacklisted from support.
(Recent configure scripts will outright reject mawk.)
Either make sure some other POSIX-compliant awk (such as gawk) can be found
in your PATH, or explicitly pass AWK=good-awk to configure.
Ncurses/Readline
The configure script searches for tputs, a symbol needed by
readline and editline. If this symbol is not found, and assuming you
actually have the library installed, locate your ncurses
library and inspect the symbol table with nm
or objdump -T.
If ncurses is in a nonstandard location, pass the root directory to the
configure option --with-ncurses=PATH.
Update: This was fixed by checking for the symbol with C linkage
instead of C++ linkage, as of 2010-03-10.
Cygwin
Disclaimer: cygwin has not been tested for quite some time (used to work once),
but has not been actively tested. (Hint: get a real *nix OS)
Issues:
- fdopen symbol not found -- ignore the test that uses it, hackt doesn't really use it
GCC errors
Most of the diagnostics you may encounter are due to the extremely
anal-retentive warning flags that I compile with by default.
- old-style-cast rejected: This occurs when including C header files
into C++ sources. There's nothing that can be done to fix installed header
files so the only solution is to amend
CXXFLAGS with
-Wno-old-style-cast.
Make sure you are using a version of flex from 2.5.4 to 2.5.31.
Newer versions are known to fail horribly (crash) with HACKT (probably due to
the extreme hackery I perform on the generated code to make it re-entrant).
Some failed tests that you might see in the check.log
are considered "not real failures".
test/prsim/memstats32.prsimtest and
test/prsim/memstats64.prsimtest may differ from their
expected results due to different data-structure layout by the compiler.
Such differences are harmless.- Likewise,
test/quarantine/memstats32-mem-01.prsimtest and
test/quarantine/memstats64-mem-01.prsimtest
may fail for the same reason.
It was discovered that the installation of the shared libraries
in src/ may fail
(target: install-pkglibLTLIBRARIES)
because install-time re-linking is order-sensitive (known automake deficiency);
dependent libraries must be installed first.
Update: The ordering was fixed as of 2010-03-10.
