Hello, > I tried to run valgrind (3.3.1) on x86 target running. The package was > build and installed fine (just adapted the /usr/lib/valgrind/uclibc.supp to > ld-uClibc-0.9.29.so). But running valgrind gives: > > root@OpenWrt:/tmp# valgrind -d > --5329:1:debuglog DebugLog system started by Stage 1, level 1 logging > requested > --5329:1:launcher no tool requested, defaulting to 'memcheck' > --5329:1:launcher no client specified, defaulting platform to 'x86-linux' > --5329:1:launcher launching /usr/lib/valgrind/x86-linux/memcheck > valgrind: failed to start tool 'memcheck' for platform 'x86-linux': No such > file or directory
> What could be wrong? I tried to set VALGRIND_LIB, LD_LIBRARY_PATH and so on > but memcheck work start :( > > I'm lucky forward to any useful hints. After some resarch I found the reason: Valgrind was compiled with wrong flags: $(MAKE) -C $(PKG_BUILD_DIR) \ $(TARGET_CONFIGURE_OPTS) \ DESTDIR="$(PKG_INSTALL_DIR)" \ CFLAGS="$(TARGET_CFLAGS)" \ AM_CFLAGS_X86_LINUX="$(TARGET_CFLAGS) -I$(PKG_BUILD_DIR)/coregrind" \ AM_CFLAGS_AMD64_LINUX="$(TARGET_CFLAGS) -I$(PKG_BUILD_DIR)/coregrind" \ AM_CFLAGS_PPC32_LINUX="$(TARGET_CFLAGS) -I$(PKG_BUILD_DIR)/coregrind" \ AM_CFLAGS_PPC64_LINUX="$(TARGET_CFLAGS) -I$(PKG_BUILD_DIR)/coregrind" \ TOOL_LDADD_COMMON="$(LIBGCC_A) $(PKG_BUILD_DIR)/abort.a" all install I changed it to: $(MAKE) -C $(PKG_BUILD_DIR) \ $(TARGET_CONFIGURE_OPTS) \ DESTDIR="$(PKG_INSTALL_DIR)" \ CFLAGS="$(TARGET_CFLAGS) -m32 -mpreferred-stack-boundary=2 -O -g -Wmissing-prototypes -Winline -Wall -Wshadow -Wpointer-arith-Wstrict-proto" \ all install Now it works (I had to symlink /usr/lib/valgrind/x86-linux/uclibc.supp to /usr/lib/valgrind/x86-linux/default.supp): root@OpenWrt:~# valgrind ls ==4369== Memcheck, a memory error detector. ==4369== Copyright (C) 2002-2007, and GNU GPL'd, by Julian Seward et al. ==4369== Using LibVEX rev 1854, a library for dynamic binary translation. ==4369== Copyright (C) 2004-2007, and GNU GPL'd, by OpenWorks LLP. ==4369== Using valgrind-3.3.1, a dynamic binary instrumentation framework. ==4369== Copyright (C) 2000-2007, and GNU GPL'd, by Julian Seward et al. ==4369== For more details, rerun with: -v ==4369== ==4369== ==4369== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0) ==4369== malloc/free: in use at exit: 0 bytes in 0 blocks. ==4369== malloc/free: 0 allocs, 0 frees, 0 bytes allocated. ==4369== For counts of detected errors, rerun with: -v ==4369== All heap blocks were freed -- no leaks are possible.
