Package: massivethreads
Version: 1.00-4
Severity: serious
Tags: patch experimental
Justification: FTBFS
User: [email protected]
Usertags: origin-ubuntu kinetic ubuntu-patch
Dear maintainer,
In Ubuntu the massivethreads package FTBFS because Ubuntu has moved to glibc
2.34 which includes a refactoring of the pthreads implementation:
[...]
libtool: compile: gcc -DHAVE_CONFIG_H -I. -Wdate-time -D_FORTIFY_SOURCE=2
-D_GNU_SOURCE -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -I/<<PKGBUILDDIR>>/include
-DMYTH_WRAP=MYTH_WRAP_DL -g -O2 -ffile-prefix-map=/<<PKGBUILDDIR>>=.
-fstack-protector-strong -Wformat -Werror=format-security -c
myth_wrap_pthread.c -fPIC -DPIC -o .libs/libmyth_dl_la-myth_wrap_pthread.o
[...]
/tmp/ccbMBQpP.s: Assembler messages:
/tmp/ccbMBQpP.s:27485: Error: symbol `sched_yield' is already defined
make[4]: *** [Makefile:852: libmyth_dl_la-myth_wrap_pthread.lo] Error 1
[...]
(https://launchpad.net/ubuntu/+source/massivethreads/1.00-4/+build/23574059)
With the help of Michael Hudson-Doyle, I've uploaded the attached
non-obvious patch to Ubuntu which fixes the build failure.
Debian currently only has glibc 2.34 in experimental, but of course will be
updating at some point.
Please consider including the attached patch in Debian.
Thanks,

+Description: hack around pthread_yield() definition for glibc 2.34 compat
+ glibc 2.34 treats pthread_yield() as a deprecated alias for sched_yield()
+ so in order to provide a wrapper around pthread_yield, some ASM magic
+ is required.
