Re: [Crash-utility] [PATCH] Makefile: crash multi-target and multithread compile support

Hi Tao Liu, Nice, I didn't think of this way. But some superfluous logs are emitted. $ make -j 8 warn lzo snappy zstd if [ -n "warn" ]; then \ ./configure -w -b; fi TARGET: X86_64 CRASH: 8.0.0++ GDB: 10.2 if [ -n "" ]; then \ ./configure -W -b; fi if [ -n "" ]; then \ ./configure -n -b; fi if [ -n "lzo" ]; then \ ./configure -x lzo -w -b; fi TARGET: X86_64 CRASH: 8.0.0++ GDB: 10.2 if [ -n "snappy" ]; then \ ./configure -x snappy -w -b; fi TARGET: X86_64 CRASH: 8.0.0++ GDB: 10.2 if [ -n "zstd" ]; then \ ./configure -x zstd -w -b; fi TARGET: X86_64 CRASH: 8.0.0++ GDB: 10.2 if [ -n "" ]; then \ ./configure -x valgrind -w -b; fi cc -c -g -DX86_64 -DLZO -DSNAPPY -DZSTD -DGDB_10_2 build_data.c -Wall -O2 -Wstrict-prototypes -Wmissing-prototypes -fstack-protector -Wformat-security cc -c -g -DX86_64 -DLZO -DSNAPPY -DZSTD -DGDB_10_2 diskdump.c -Wall -O2 -Wstrict-prototypes -Wmissing-prototypes -fstack-protector -Wformat-security ar -rs crashlib.a main.o tools.o global_data.o memory.o filesys.o help.o task.o build_data.o kernel.o test.o gdb_interface.o net.o dev.o bpf.o printk.o alpha.o x86.o ppc.o ia64.o s390.o s390x.o s390dbf.o ppc64.o x86_64.o arm.o arm64.o mips.o mips64.o sparc64.o extensions.o remote.o va_server.o va_server_v1.o symbols.o cmdline.o lkcd_common.o lkcd_v1.o lkcd_v2_v3.o lkcd_v5.o lkcd_v7.o lkcd_v8.o lkcd_fix_mem.o s390_dump.o netdump.o diskdump.o makedumpfile.o xendump.o lkcd_x86_trace.o unwind_v1.o unwind_v2.o unwind_v3.o unwind_x86_32_64.o unwind_arm.o xen_hyper.o xen_hyper_command.o xen_hyper_global_data.o xen_hyper_dump_tables.o kvmdump.o qemu.o qemu-load.o sadump.o ipcs.o ramdump.o vmware_vmss.o vmware_guestdump.o xen_dom0.o kaslr_helper.o CXXLD gdb make: 'lzo' is up to date. make: 'snappy' is up to date. make: 'zstd' is up to date. With "@if" and "configure -q", we can reduce the former half ones, but also multiple executions of configure can be removed with this way. +ifeq ($(findstring warn,$(MAKECMDGOALS)),warn) +CONF_TARGET_FLAG += -w +endif +ifeq ($(findstring Warn,$(MAKECMDGOALS)),Warn) +CONF_TARGET_FLAG += -W +endif ... warn: all Warn: all ... What do you think? But even with this way, "make: 'lzo' is up to date." is still emitted. $ make -j 8 warn lzo snappy zstd TARGET: X86_64 CRASH: 8.0.0++ GDB: 10.2 cc -c -g -DX86_64 -DLZO -DSNAPPY -DZSTD -DGDB_10_2 build_data.c -Wall -O2 -Wstrict-prototypes -Wmissing-prototypes -fstack-protector -Wformat-security cc -c -g -DX86_64 -DLZO -DSNAPPY -DZSTD -DGDB_10_2 diskdump.c -Wall -O2 -Wstrict-prototypes -Wmissing-prototypes -fstack-protector -Wformat-security ar -rs crashlib.a main.o tools.o global_data.o memory.o filesys.o help.o task.o build_data.o kernel.o test.o gdb_interface.o net.o dev.o bpf.o printk.o alpha.o x86.o ppc.o ia64.o s390.o s390x.o s390dbf.o ppc64.o x86_64.o arm.o arm64.o mips.o mips64.o sparc64.o extensions.o remote.o va_server.o va_server_v1.o symbols.o cmdline.o lkcd_common.o lkcd_v1.o lkcd_v2_v3.o lkcd_v5.o lkcd_v7.o lkcd_v8.o lkcd_fix_mem.o s390_dump.o netdump.o diskdump.o makedumpfile.o xendump.o lkcd_x86_trace.o unwind_v1.o unwind_v2.o unwind_v3.o unwind_x86_32_64.o unwind_arm.o xen_hyper.o xen_hyper_command.o xen_hyper_global_data.o xen_hyper_dump_tables.o kvmdump.o qemu.o qemu-load.o sadump.o ipcs.o ramdump.o vmware_vmss.o vmware_guestdump.o xen_dom0.o kaslr_helper.o CXXLD gdb make: 'lzo' is up to date. make: 'snappy' is up to date. make: 'zstd' is up to date. Is there any way not to print these messages? Thanks, Kazu
