lightning: new package GNU lightning is a library that generates assembly language code at run-time. https://www.gnu.org/software/lightning/ [Thomas: - Wrap list of architectures in Config.in - Introduce an explicit Config.in option for the disassembler support, since it needs both binutils and zlib, which may not be easy to guess. - Add hash file. - Bump to version 2.0.5. - Add patch to fix cross-compilation issues on ARM and x86 due to AC_RUN_IFELSE() tests. - Adjust license information: the library is actually under LGPLv3+, not GPLv3. There is a COPYING file with the text of the GPLv3 in the code base, but this license doesn't seem to be used in anything that is actually installed. - Add AUTORECONF = YES since we're now patching configure.ac. - Add missing dependency on zlib for the disassembler support. - Add a special LIBS=-lintl when enabling the disassembler support because binutils libraries use gettext functions, but they are not linked against libintl.] Signed-off-by: Paul Cercueil <paul@crapouillou.net> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

lightning: add -lintl only when needed Adding -lintl to LIBS causes a failure in the configure phase when using a toolchain which already has locale support because the intl library is not present in the staging area. We fix this by adding -lintl only when is needed. This is the configure error: checking whether the C compiler works... no configure: error: in `/br/output/build/lightning-2.0.5': configure: error: C compiler cannot create executables See `config.log' for more details This is the message in the config.log: configure:3351: /br/output/host/usr/bin/mips-linux-gnu-gcc -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 conftest.c -lintl >&5 /br/output/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/4.9.1/../../../../mips-linux-gnu/bin/ld: cannot find -lintl collect2: error: ld returned 1 exit status Fixes: http://autobuild.buildroot.net/results/280/28006ab35379a9b7f380d40b99a760bec1b69e84/ [Thomas: - Adjust the fix to not add a dependency on gettext: lightning doesn't depend on gettext. It is just that binutils libraries are linked against libintl when available, and we need to add -lintl explicitly in such cases.] Signed-off-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
