Hi, I'm hunting some race condition in my plugins which produce a segfault in libc or libavahi (still searching the right packages with debug symbols, race condition may be related to having to dbus-mainloops in dbus2vdr and avahi4vdr, but I don't know yet). While investigating this I found something about the option "-pthread" of g++.
According to g++'s manpage this will set the right options for the preprocessor and compiler so the program can use the pthreads lib. Especially it will set -D_REENTRANT and -lpthread etc. vdr seems only to use -lpthread and no other pthread-specific options. I'm not an expert on this topic, so I would like to know if someone can shed some light on this. Makefile may than be patched with: ========== --- a/Makefile +++ b/Makefile @@ -14,12 +14,12 @@ CFLAGS ?= -g -O3 -Wall CXX ?= g++ -CXXFLAGS ?= -g -O3 -Wall -Werror=overloaded-virtual -Wno-parentheses +CXXFLAGS ?= -g -O3 -Wall -Werror=overloaded-virtual -Wno-parentheses -pthread CDEFINES = -D_GNU_SOURCE CDEFINES += -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -LIBS = -ljpeg -lpthread -ldl -lcap -lrt $(shell pkg-config --libs freetype2 fontconfig) +LIBS = -ljpeg -ldl -lcap -lrt $(shell pkg-config --libs freetype2 fontconfig) INCLUDES ?= $(shell pkg-config --cflags freetype2 fontconfig) # Directories: ========== Recompiled vdr and plugins do run as before (haven't solved my segfault). What do you think? Lars. _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
