2016-09-26use a single libc and deduplicate threading codeWaldemar Brodkorb
Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance
2016-08-16linuxthreads: install libpthread_nonshared.aWaldemar Brodkorb
This is useful to build native gcc on targets supporting Linuxthreads instead of NPTL.
2016-06-23libs: install backward compatibility symlinksAlexey Brodkin
Simplify the switch from uClibc to uClibc-ng. Apps already built against uClibc-0.9.x.y require .so.0 libs to present on target which in case of current uClibc-ng is not the case and those apps could not be run. This change creates symlinks from .so.1 to .so.0 for most of other libs in the same way as it was done by 23e96d89b6ab "ldso: install backward compatibility symlink by default" Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Waldemar Brodkorb <wbx@uclibc-ng.org> Cc: Vineet Gupta <vgupta@synopsys.com> Cc: Anton Kolesov <akolesov@synopsys.com>
2016-05-18remove linuxthreads.new, rename linuxthreads.oldWaldemar Brodkorb
Linuxthreads.new isn't really useful with the existence of NPTL/TLS for well supported architectures. There is no reason to use LT.new for ARM/MIPS or other architectures supporting NPTL/TLS. It is not available for noMMU architectures like Blackfin or FR-V. To simplify the live of the few uClibc-ng developers, LT.new is removed and LT.old is renamed to LT. LINUXTHREADS_OLD -> UCLIBC_HAS_LINUXTHREADS

2014-10-03linuxthreads: fix compile error for non-MMUWaldemar Brodkorb
Otherwise you get following linking error, because of missing functions in libc.a: undefined reference to `__libc_enable_asynccancel' Fix by Thorsten Glaser while hacking session.

2010-04-22nptl: proper soname handlingNatanael Copa
Since sublevel releases are not ABI compatible we need to adjust the soname to include the sublevel version. This makes it possible to install ABI incompatible versions of the library side by side so clean upgrades are possible.

2008-10-18- do not list non-existing files in the threads prerequisitesBernhard Reutner-Fischer
2008-10-17- fix toggling thread implementation.Bernhard Reutner-Fischer
Previously the old headers were left in include/ leading to spurious compile failures. This is ugly as it can get (we resort to sneaking -L in for the moment) but good enough for now. The worst thing which can happen is that we ln these headers once per invocation of make, nothing more. If some installation of make(1) complains about the "-L" then wrap it in ifneq ($(findstring check-symlink,$(.FEATURES)),)

2008-06-04- strip the targets and not prerequisitesBernhard Reutner-Fischer
- tidy up PTHREADS_DEBUG_SUPPORT by using per-target STRIP_FLAGS for the few This fixes the spurious rebuilds bernd and vda were seeing with libpthreads.
2008-06-01A slight improvement over my previous commit which ensured we always rebuildBernd Schmidt
libc when one of the source files changes. Since there are more places which want to depend on $(libc), fix them all to use a new variable $(libc.depend), which contains the filename for which we have a rule.

2007-10-13- use the compiler-driver instead of the linkerBernhard Reutner-Fischer
- adjust setting flags accordingly to use (hardcoded, see below) -Wl, Potential improvements: *) --warn-unresolved-symbols should perhaps be used for all libs *) eventually rename LDFLAGS to CC_LDFLAGS *) probe for compiler driver's notion of flag to use for passing in linker flags (i.e. don't hardcode "-Wl,")
