Code around it by using `wcsncpy()` and `wcscat()` combined with a
manual length check. This should be enough to make YQ2 working on Win
XP again. Please note, that we don't support any Windows older than
10. However we still try to avoid breaking them.
Based on an idea by @ carlo-bramini, closes#994.
I was reported a strange problem were GL3 is crashing with SIGBUS while
enumerating the GL extensions. To me it looks like a problem in Nvidias
FreeBSD driver, which for some reason doesn't reproduce on my machine.
However it' hard to tell what exactly happens without a full backtrace
and the user is unable to provide one... For the future try to handle
SIGBUS to catch those problems.
For example, on Windows with AMDs drivers, GLES3 isn't supported,
so CreateSDLWindow() will fail. We should just try the regular GL3
renderer then instead of exiting with Com_Error()
Also make (Windows') Sys_Error() print to stdout (in addition to stderr),
so errors end up in stdout.txt as well (like all other messages).
Older ARM ABIs like Debian armel (ARMv5 EABI softfloat) don't use
or require a hardware FPU, so they can't execute the fmrx and fmxr
instructions. Only do this in hardfloat configurations that guarantee
VFP instructions are available.
The client might not be practically usable on ARM softfloat (although
nobody has reported that it isn't...) but the dedicated server is probably
fine, and ceasing to be able to build either would be a regression.

At least for LLVM / Clang the -fsanitize= option must be passed to the
linker before any objects or libraries, otherwise the sanitizers will
either noch link or are disfunctional. Split LDFLAGS into LDFLAGS for
flags and LDLIBS for librariers, pass LDFLAGS before any objects and
LDLIBS after all objects. While at it set RTLD_NODELETE so that shared
libs opened by dlopen() are never deleted from memory when building
with sanitizers.
Until 7.45 we supported adding non existent dirs to the search path,
8.00 bails out if it cannot at a dir. It turned out that some users
install the binary through their package management (SYSTEMWIDE is set),
but use local game data. This case was broken, because the SYSTEMDIR
doesn't exist. Fix this by marking the SYSTEMDIR as optional.
Closes#724.
Specify correct protection flags when calling mmap() on FreeBSD.
prot | PROT_MAX (prot) are the correct flags because just PROT_MAX
(prot) leaves current protection flags set to PROT_NONE which causes
segmentation fault when reading or writing to the mapped region.
Since 1a913eb we're calling realpath() on every dir and bail out if the
real path isn't available. If the game is started the first time, the
configuration dir doesn't exist at the first realpath() call and the
game errors out. Always create the configuration dir when determining
it's path.
This didn't happen on Windows because the configuration dir was created
when opening stdout.txt right after we entered main().
TODO: Sys_Mkdir() should grow at leas a little bit error handling. We're
silently ending up in -portable mode if the configuration dir couldn't
created.
Working with canonical fullpathes everywhere makes debugging easier.
And it will be used in a later commit to make sure, that each path is
added only once.
Normally stdout and stderr are buffered. In case of a crash the last
lines aren't written to the stdout.txt, making post mortem debugging
difficult. Forcing both FDs to unbuffered mode ensures that everything
gets written. The performance impact is negliable.
Even tough it is a multi user os, due to BeOs heritage and being backwards
compatible with, the desktop runs as root, thus its dog get eaten after all...
