Error when compiling go-yara about go-yara

Thank you very much for your help and your awesome projects!

You seem to be conflating several things, cargo-cult style.

Since you seem to be fine with "tainting" your build environment by installing stuff to /usr that does not come from packages, try the following:

• pass --prefix=/usr to the configure run.
• don't copy yara.pc
• don't set CGO_* variables.
• Set -extldflags as described in the README for static builds.

Used the following command lines, I built the Linux binary successfully.

wget https://codeload.github.com/VirusTotal/yara/tar.gz/refs/tags/v4.2.2 -O v4.2.2.tar.gz
tar -zxvf v4.2.2.tar.gz
cd yara-4.2.2/ && ./bootstrap.sh
cd yara-4.2.2/ && ./configure --disable-shared --enable-static --without-crypto --prefix=/usr
cd yara-4.2.2/ && make && make install
export YARA_SRC=$PWD/yara-4.2.2
cd project && go env -w GO111MODULE=on && go env && go mod tidy
cd project && go build -ldflags '-extldflags \"-static\"' -tags yara_static -o ../../build/yara_engine

Still, I got a warning, is there anything more I should do?

Great.

Yeah, here things get more complicated. GNU libc is not intended to be linked statically, particularly name lookups (hostnames, usernames, DNS…) will not work.

If you can live with that, just do a static-only build of YARA as you are doing now and omit the -extldflags parameter to go.
