Since Wireshark v2.9.0rc0-2266-g7e88bb5e53, building fuzzing binaries is
better integrated in the Wireshark build system. While that change was
supposed to be backwards compatible, unfortunately the resulting fuzzer
binaries are dynamically linked due to how cmake caches library paths.
The very first cmake invocation must be invoked with -DOSS_FUZZ=ON.
Changes:
- Use ninja for better control of parallel linker jobs.
- Installing files (make install) is no longer needed.
- Avoid setting a long list of cmake options (BUILD_xxx=OFF).
- Remove fortify comment, it does not belong here.
- Remove lemon workaround, it is fixed since v2.9.0rc0-2273-gbb2caa2a9f.
I added auto-building fuzzshark to wireshark, to avoid oss-fuzz build being broken,
but it actually broke the build:
Step #3: CC tools/oss-fuzzshark/fuzzshark-fuzzshark.o
Step #3: CC tools/oss-fuzzshark/fuzzshark-StandaloneFuzzTargetMain.o
Step #3: CCLD fuzzshark
Step #3: /usr/bin/ld: epan/.libs/libwireshark.a(packet-ipsec.o): undefined reference to symbol 'gpg_strerror@@GPG_ERROR_1.0'
Step #3: //lib/x86_64-linux-gnu/libgpg-error.so.0: error adding symbols: DSO missing from command line
Step #3: clang-6.0: error: linker command failed with exit code 1 (use -v to see invocation)
Step #3: Makefile:1821: recipe for target 'fuzzshark' failed
