For the jq_state used by the jq utility, the JQ_LIBRARY_PATH attribute will always be set, but, in general, it is possible that it might not be. If it is not set, jq_get_lib_dirs() will return jv_invalid(). That is not good, because some code in linker.c expects it to always returns an array. This patch makes jq_get_lib_dirs() return an empty array if JQ_LIBRARY_PATH is not set to prevent problems. This issue made OSS fuzz trigger failed assertions every time it tried to compile a script that uses "include". Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=61796
jq
jq is a lightweight and flexible command-line JSON processor akin tosed,awk,grep, and friends for JSON data. It's written in portable C and has zero runtime dependencies, allowing you to easily slice, filter, map, and transform structured data.

Building from source
Dependencies
- libtool
- make
- automake
- autoconf
Instructions
git submodule update --init # if building from git to get oniguruma
autoreconf -i # if building from git
./configure --with-oniguruma=builtin
make -j8
make check
sudo make install
Build a statically linked version:
make LDFLAGS=-all-static
If you're not using the latest git version but instead building a released tarball (available on the release page), skip the autoreconf step, and flex or bison won't be needed.
