Therefore, on mac, you need to recompile to generate the jnisigcheck.so file.

---

Compile jnisigcheck.so

---

Download and unzip tls_sig_api-src.tar.gz
into the src directory and view the Makefile

$ tar -zxvf tls_sig_api_src.tar.gz
$ cd tls_sig_api-src/src
$ vim Makefile

Makefile

CPP = g++
CC = gcc

clean:  
    -rm -f *.o *.so *.a tls_licence_tools TAGS $(TARGETS)

---

You can see that jnisigcheck.so is generated using make jni. After executing the command, jnisigcheck.so was not generated as we imagined, and some dependency libraries need to be resolved: jni_md.h, in the code ../linux/ $ (ARCH)/lib/jsoncpp/libjsoncpp.a ( $ ( ARCH)=64) and missing ../openssl-dynamic/lib/libcrypto.a files.

---

Solve the problem

Solve the problem of jni_md.h (copy jni_md.h)

$ cd $JAVA_HOME/include
$ sudo cp darwin/jni_md.h .

compile jsoncpp

$ brew install scons
$ cd tls_sig_api-src/jsoncpp-src-0.5.0
$ python /usr/local/bin/scons platform=linux-gcc

The result of the execution is that
linux-gcc-4.2.1/libjson_linux-gcc-4.2.1_libmt.a
linux-gcc-4.2.1/libjson_linux-gcc-4.2.1_libmt.dylib is generated in the libs directory

compile openssl

// 进入tls_sig_api-src目录
$ tar -zxvf openssl-1.0.2a.tar.gz
$ mv openssl-1.0.2a openssl_x86_64
$ cd openssl_x86_64
$ ./Configure darwin64-x86_64-cc -shared
$ make

This generates libcrypto.a in the current directory

Create a soft chain and
enter tls_sig_api-src/src

$ mkdir -p ../linux/64/lib/jsoncpp
$ ln -s `cd ..;pwd`/jsoncpp-src-0.5.0/libs/linux-gcc-4.2.1/libjson_linux-gcc-4.2.1_libmt.a ../linux/64/lib/jsoncpp/libjsoncpp.a
$ mkdir -p ../openssl-dynamic/lib/
$ ln -s `cd ..;pwd`/openssl_x86_64/libcrypto.a ../openssl-dynamic/lib/libcrypto.a

When creating a link, the source needs to fill in the absolute path, so there is the above cd ..;pwd.

Compile jnisigcheck.so

//在src目录下，执行一下命令，则生成`jnisigcheck.so`
$ make clean
$ make jni

At this time, there is a jnisigcheck.so file in the src directory. Change
jnisigcheckLibPath to "tls_sig_api-src/src/jnisigcheck.so", and
you can run it on mac.
