[Building MIRAI] wrapper.h:1:10: fatal error: 'z3.h' file not found

[hermanventer]

I believe this problem is already fixed on https://github.com/hermanventer/MIRAI, which should now be regarded as the source of truth for MIRAI since no-one at Meta seems interested in merging pull requests into this repo.

@hermanventer I tried with your fork and I got the same error.

It worked for me when I added the path of z3.h.

CPATH=/usr/local/Cellar/z3/4.9.1/include/ cargo install --locked --path ./checker

[hermanventer]

Could you append a full log of a session where you follow the installation instructions and it fails?

[garbervetsky]

@hermanventer This are the steps I followed:
./setup.sh everything looks fine.

From InstallationGuide.md:

For macOS the binary will have to be placed somewhere where it can be found and dynamically loaded by the Rust runtime.
You'll also need the z3 header files.

On an Intel Mac, do

sudo cp binaries/libz3.dylib /usr/local/lib
sudo cp include/*.h /usr/local/include

[garbervetsky]

Makes sense. I did copied the library but not the include files because is not in the instructions :-)
Thanks @hermanventer

Hi, where would I need to place the files on an ARM Mac?

[hermanventer]

This step is no longer required. You can just build MIRAI. See the current installation guide.

Hi @hermanventer, I'm installing the z3 package for another project I'm working with and have the same issue as above. I need some help because the /include files are not on the PATH I believe?

[hermanventer]

Z3 is now statically linked into MIRAI, so there is no dependency or interference from any other Z3 package you may have.
