Getting segment fault on intel MacOS. #174

Closed RoastedGoose closed 1 year ago

RoastedGoose commented 1 year ago

Getting segment fault on intel MacOS. After “sudo make install” and simply called “initPairing()”, it caught exception “exc bad accss code exc I386 gpflt.” when running “mulUnitN()”. While the original build test works fine.

What is the CPU? What are the compiler options to build?

RoastedGoose commented 1 year ago

x86-64 intel i5 with clang++. Just follow the build method below: For x86-64 Linux and macOS. mkdir build cd build cmake .. make Then “sudo make install”. Create a new cpp file and include <mcl/bls12_381>, and link mcl and gmp libraries when compiling.

Okay, I verified the problem. It reproduces on only Intel Mac with CMake. There is no problem on the other intel Linux, M1 Mac and intel Mac with Makefile. I'll investigate the reason, but could you please use libmcl.a built by make for a while?

RoastedGoose commented 1 year ago

make works, thanks!

Hello, is this(cmake) fixed? I got the problem again on my mac intel.

Please show me what kind of code you build and how you build it.

The following commands go well.

mkdir build
cd build
cmake .. -DMCL_BUILD_TESTING=ON -DMCL_BUILD_SAMPLE=ON
make -j
bin/bls12_test
...
clang -v
