If I captured that correctly, i could submit a patch to README on how to do this statically?: ----------------- Building 'crash' statically (w/lzo2 support) ============================================ To attempt to build 'crash' statically with pretty common lzo2 support (used by 'makedumpfile'), the static library liblzo2.a is needed. However, this is not available in Fedora 24 .rpm packages :-(. To build it yourself, try: mkdir lzo2_temp cd lzo2_temp/ yumdownloader --source lzo-devel pm2cpio lzo-2.08-8.fc24.src.rpm | cpio -idv tar xf lzo-2.08.tar.gz cd lzo-2.08/ run ./configure if need-be make liblzo2.a Then after downloading the crash repo: https://github.com/crash-utility/crash.git Specify to build it statically in the crash/ directory by creating a file called LDFLAGS.extra with a couple of static flags: $ cat LDFLAGS.extra -static -static-libgcc and in crash/gdb-X.Y/Makefile at TOPLEVEL_CONFIGURE_ARGUMENTS variable add: --enable-static=yes (example: # The gcc driver likes to know the arguments it was configured with. TOPLEVEL_CONFIGURE_ARGUMENTS=./configure --with-separate-debug- dir=/usr/lib/debug --with-bugurl= --with-expat=no --with-python=no -- disable-sim --enable-static=yes) and back in the top crash/ directory build the whole thing with the lzo2 library: $ make lzo (adds to LDFLAGS.extra and creates CFLAGS.extra) > > > > Dave > > > > -- > > Crash-utility mailing list > > Crash-utility@xxxxxxxxxx > > https://www.redhat.com/mailman/listinfo/crash-utility > > -- > Crash-utility mailing list > Crash-utility@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/crash-utility -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
